      Abstract:Objective: To investigate the application of hybrid procedure in treatment of complex aortic diseases. Methods: The clinical data of the 12 patients with complex aortic disease undergoing hybrid treatment from August 2007 to August 2012 were retrospectively analyzed. Of the patients, 9 cases had aortic dissection, and 3 cases had thoracoabdominal aortic aneurysm. The procedures included various prosthetic bypass graftings combined with endovascular covered stent placement. Results: Technical success was achieved in all patients. Proximal type I endoleak occurred in one patient with aortic dissection after operation, for which no treatment was given; one patients with aortic dissection died during perioperative period due to severe mediastinal infection; the rest of the patients recovered well after operation. Follow-up was obtained in 8 patients for 3 months to 2 years, and all of them were alive without endoleak or other complications. Conclusion: Hybrid procedure is a viable alternative to patients with complex aortic diseases.

      Abstract:Objective: To investigate the method of endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA) combined with iliac artery aneurysm. Methods: The clinical data of 35 patients with AAA and concomitant iliac artery aneurysm undergoing EVAR from August 2007 to March 2014 were retrospectively analyzed. The patients consisted of 9 cases complicated with unilateral internal iliac artery aneurysm, one case with bilateral internal iliac artery aneurysm, 14 cases with unilateral common iliac artery aneurysm (diameter larger than 18 mm) and 11 cases with bilateral common iliac artery aneurysm. The endovascular procedures performed included internal iliac artery embolization followed with stent coverage, simple stent coverage of the internal iliac artery aneurysm, use of a braided stent, and Sandwich technique for internal iliac artery endorevascularization. Results: All endovascular procedures were successfully performed, with an average operative time of (125± 40) min and blood loss of (173±65) mL. Intraoperative endoleak was observed in 8 patients (22.9%), including type I endoleak in 4 cases (2 from the proximal and 2 from the distal attachment site) which were all resolved after balloon dilatation, type III endoleak in one case which was resolved by dilatation plus adjunctive coil embolization, type II endoleak in 2 cases and type IV endoleak in one case, none of which received further intervention. Postoperative follow-up was conducted for 6 to 26 months in the 35 patients, during which time no aneurysmal rupture occurred; AAA enlargement was found in 2 cases 6 months after procedure, which was identified as distal type I endoleak by radiography and resolved by coil embolization, and no aneurysmal enlargement occurred in any of the remaining 33 cases. Conclusion: Ideal short-term results may be obtained in patients with AAA and concomitant iliac artery aneurysm by appropriate treatment of the internal iliac artery and then suitable endovascular techniques according to the diameter of the common iliac artery.

      Abstract:Objective: To systematically evaluate the efficacy of surgical and conservative treatment for small-diameter abdominal aortic aneurysm (AAA). Methods: The randomized controlled trails (RCTs) comparing surgical (endovascular aortic repair and open surgery) and conservative treatment for small-diameter AAA were collected by searching the national and international databases. After assessment of methodological quality of the included studies according to the Cochrane Reviewers’ Handbook criteria, Meta-analysis was performed by using RevMan 5.1 software. Results: Four RCTs were finally included, with a total of 3 314 patients, of whom 1 680 cases underwent surgical treatment and 1 634 cases underwent conservative treatment. Results of Meta-analyses showed no significance difference between the two groups of patients in all-cause mortality (SMD=0.97, 95% CI=0.68–1.38), aneurysm-related mortality (SMD=0.81, 95% CI=0.56–1.17), incidence of aneurysm rupture (SMD=0.49, 95% CI=0.09–2.54) and mortality within postoperative 30 d or during hospitalization (SMD=0.88, 95% CI=0.60–1.29) (all P>0.05). Conclusion: In treatment of small-diameter AAA, the outcomes between surgery and conservative treatment are similar. However, the clinical significance of this conclusion is uncertain, and the authors based on comprehensive analysis deem that small-diameter AAA still needs aggressive surgical treatment.

      Abstract:Objective: To investigate the indications, advantages and complications of using combined brachial and femoral approach for endovascular treatment of subclavian artery occlusion. Methods: Fifty-seven patients with subclavian arterial occlusive disease undergoing endovascular therapy via the combined approach in Department of Vascular Surgery, Xuanwu Hospital of Capital Medical University from January 2011 to June 2014 were reviewed. The pathological characteristics of the patients, success rate of operation, advantages of the combined approach, complications, and follow-up results were analyzed. Results: There was three lesion types among the patients, which included subclavian artery occlusion that failed to be recanalized by anterograde approach (31 cases), the stenosis or occlusion located in the opening of right subclavian artery (16 cases), and the distal subclavian artery stenosis or occlusion adjacent to the opening of the vertebral artery (10 cases). The success rate of endovascular treatment was 91.2% for the entire group, and puncture complications occurred in 3 cases. The stent patency rate at postoperative 6, 12, 24, and 36 months was 100%, 100%, 90% and 77.7%, respectively. Conclusion: For subclavian artery occlusion difficult to be recanalized by conventional approach, the combined approach can effectively improve the recanalization rate, with the advantages of helping to ensure the accuracy of stent positioning and reduce the occurrence of complications.

      Abstract:Objective: To investigate the short and medium term efficacy of Viabahn covered stent in treatment of arteriosclerosis obliterans of the lower limbs. Methods: The clinical data of 73 patients (73 affected limbs) with arteriosclerosis obliterans of the lower limb undergoing endovascular treatment from January 2013 to January 2014 were retrospectively analyzed. Of the patients, 32 cases underwent endovascular Viabahn covered stent placement (Viabahn stent group), and 41 cases received bare-metal stent placement (bare-metal group). The clinical outcomes between the two groups of patients were compared. Results: In Viabahn stent group compared with bare-metal stent group, the primary patency rate at postoperative 3 and 6 months showed no significant difference (96.8% vs. 90.2%; 87.5% vs. 75.6%, both P>0.05), but it was significantly increased at postoperative 9 and 12 months (84.4% vs. 63.4%; 75.0% vs. 51.2%, both P<0.05). Log-rank test result showed that the 12-month patency rate in Viabahn stent group was significantly higher than that in bare stent group (P<0.05). The ankle brachial index (ABI) at postoperative 12 months between the two groups had no significant difference (P>0.05). Conclusion: Viabahn covered stent placement following endovascular angioplasty has significant short and medium term efficacy in treatment of arteriosclerosis obliterans of the lower limbs, and it may be a therapeutic option for arteriosclerosis obliterans of the lower limbs with lesions close to, and especially those crossing over the knee joint.

      Abstract:Objective: To investigate the effectiveness and feasibility of subintimal angioplasty/stent placement through retrograde popliteal approach for long superficial femoral artery sclerotic occlusion with failed recanalization by conventional endovascular antegrade approach. Methods: The data of fifty patients with long superficial femoral artery sclerotic occlusions, in whom the guide wire and catheter failed to advance into the distal true lumen through the occlusive lesions by antegrade ipsilateral or contralateral femoral approach, and then underwent subintimal angioplasty by retrograde popliteal approach were analysed. Results: The immediate success rate of stent placement was 100%, with primary and secondary patency rate of 48.0% and 92.0% at 12 months. In all the patients, the ankle brachial index (ABI) was increased and Rutherford classification was improved significantly compared with those before operation (all P<0.05). Postoperative limb swelling occurred in 5 patients and popliteal pseudoaneurysm developed in 3 patients at 3 months after operation, which were all improved after treatment. Restenosis occurred after one year in 16 patients (32.0%). Conclusion: Subintimal angioplasty/stent placement through retrograde popliteal approach is effective and feasible in treatment of long superficial femoral artery sclerotic occlusion with failed recanalization after conventional endovascular antegrade approach.

      Abstract:Objective: To investigate the influence of renal capsule block on gastric myoelectrical activity and motility in rats, and provide a theoretical basis for using this method in treatment of gastrointestinal motor disorders. Methods: Thirty-six SD rats were equally randomized into 3 groups, and then underwent intraperitoneal injection of atropine, neostigmine or normal saline to create the models of gastrointestinal motor suppression (suppression group), gastrointestinal hyperactivity (hyperactivity group), or normal control (control group), respectively. Rats in each group underwent renal capsule block procedure by renal capsule injection of lidocaine. The gastric electrical activity and gastric residual rate in rats of each group were detected and compared. Results: Compared with control group after model creation, the average peak amplitude and cycle length of the electrogastrography were reduced, and gastric residual rate was increased significantly in suppression group, while the changes in these parameters in hyperactivity group were opposite to those in hyperactivity group (all P<0.05). After renal capsule block, all the parameters in control group showed no significant change compared with those before renal capsule block (all P>0.05), while the average peak amplitude and cycle length of the electrogastrography in suppression group were elevated and gastric residual rate was decreased significantly compared with the values before renal capsule block, and the average peak amplitude and cycle length of the electrogastrography in hyperactivity group were decreased and gastric residual rate was increased significantly compared with those before renal capsule block (all P<0.05). Conclusion: Renal capsule block exerts no obvious impact on normal gastric myoelectrical activity and motility, but has a bidirectional correction effect on abnormal gastric myoelectrical activity and motility.

      Abstract:Objective: To present and analyze the diagnosis and treatment of the delayed massive gastrointestinal hemorrhage caused by fistula formation between pseudoaneurysm of the celiac trunk branches and digestive tract following abdominal surgery. Methods: The clinical data of 5 patients from January 2013 to September 2014 who developed massive gastrointestinal hemorrhage after abdominal tumor surgery and were identified as fistula formation between pseudoaneurysm of the branches and digestive tract by angiography were analyzed. Results: Of the 5 patients, the average time to postoperative gastrointeatinal hemorrhage was 53.6 d; the pseudoaneurysm was located in the splenic artery in 2 cases, in the common hepatic artery in 2 cases and in the left hepatic artery in one case; 4 cases underwent embolization therapy after angiography, and one case underwent covered stent implantation. No severe postoperative complications or perioperative death occurred. Postoperative follow-up was conducted for 6 to 16 months, during which time, no rupture and hemorrhage of the pseudoaneurysm occurred, but there was sudden death of unknown cause in one case who had undergone common hepatic artery covered stent implantation. Conclusion: The fistula between pseudoaneurysm of celiac axis branches and digestive tract is a rare but fatal complication after abdominal surgery and its awareness should be enhanced. Angiography and endovascular repair are preferred for its diagnosis and treatment, and avoidance of iatrogenic injury may be critical for reducing the incidence of this condition.

      Abstract:Objective: To report the experience in diagnosis and treatment as well as the surgical complications of carotid body tumors (CBTs). Methods: The data of 24 CBT patients with a total of 30 CBTs treated from January 1999 to September 2012 were retrospectively reviewed. Of the patients, 6 cases had bilateral lesions, and 18 cases had a unilateral lesion. Results: All the 24 patients (30 CBTs) underwent surgical treatment that included simple tumor excision of 17 Shamblin I tumors, tumor removal plus external carotid artery resection of 7 Shamblin II tumors, and tumor removal plus partial internal carotid artery resection and reconstruction of 6 Shamblin III tumors. Tumors were completely removed in all the 24 patients, and no operative death occurred, Transient postoperative cranial nerve injury occurred in 5 cases (16.7%) and permanent postoperative cranial nerve damage occurred in one case (3.33%). Follow-up lasted for 1 year to 15 years, and no delayed complications or tumor recurrence occurred. Conclusion: Surgery is the most effective treatment for CBTs, and favorable outcomes may be obtained by appropriate surgical procedures decided according to the size of the tumor and the relationship between the tumor and its adjacent arteries.

      Abstract:Objective: To investigate the impact of operation for lower extremity superficial varicose veins on function of deep venous valves in patients with primary deep vein valvular incompetence (PDVI). Methods: The clinical data of 94 PDVI patients (95 limbs) undergoing surgery for superficial varicose veins of the lower extremity were retrospectively analyzed. The changes in deep venous valve function before and after operation were compared. Results: All the 95 limbs were definitely diagnosed to have PDVI by color Doppler ultrasonography before operation, in which according to CEAP classification, 31 limbs were classified as C2, 22 were C3, 25 were C4, 7 were C5, and 10 were C6, respectively. Results of color Doppler ultrasonography half a year after operation showed that valvular function returned to normal in 40 limbs (42.1%), improved in 21 limbs (22.1%), was unable to be determined in 23 limbs (24.2%), and the valvular incompetence was aggravated in 11 limbs (11.6%), 10 of which were classified as C5–6 by preoperative CEAP classification; the average valve closure time (VCT) and maximum velocity (Vmax) of the 95 limbs were all significantly decreased compared with preoperative values (both P<0.05). Conclusion: The valvular function of deep veins in PDVI patients may be improved to some extent after operation for lower extremity superficial varicose veins. However, for patients with C5–6 classification, the synchronous repair of deep vein valves is recommended because of the serious damage of their valvular function.

      Abstract:Objective: To investigate the vascular hemodynamic changes during the formation of obstructive membrane of the inferior vena cava (IVC) in Budd-Chiari syndrome (BCS) using computer simulation methods. Methods: The vascular model of BCS caused by membranous obstruction of the IVC was established based on MRA slice images, and then numerical simulation of hemodynamic parameter changes was demonstrated by using Ansys Fluent software. Results: The vascular model of BCS with membranous obstruction of the IVC was established successfully. The results of numerical simulation experiments demonstrated that during the formation of the obstructive membrane, there was a low flow speed region between the membrane and the region of confluence of the IVC and the three main hepatic veins, which increasingly enlarged with the extension of the membrane; with the development of the membrane, the low shear stress field located close to the IVC and the right hepatic vein was continuously amplified, and moreover, the shear stress gradually increased. Conclusion: The formation and development of the obstructive membrane of the IVC is a process of slow change, which may be closely related to alterations in shear stress of the wall of IVC.

      Abstract:Objective: To investigate the relationship between thyroid dysfunction and blood lipid level. Methods: Two hundred patients with thyroid function problems admitted during April 2013 to March 2015 were enrolled for the study, including 100 cases each with hyperthyroidism or hypothyroidism, and 80 participants undergoing health maintenance examination during the same period served as control. The levels of thyroid hormones and blood lipids in all subjects were measured, and the correlation between their levels was analyzed. Results: By univariate analysis, significant difference was found in all the studied thyroid hormones and blood lipids among the three populations (all P<0.05). Correlation analysis in patients with abnormal thyroid function showed that the level of thyroid stimulating hormone (TSH) had a positive correlation with the levels of total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), and apolipoprotein B100 (ApoB10) (r=0.695, 0.714, and 0.632); the level of free triiodothyronine (FT3) had a negative correlation with the levels of TC, LDL-C and ApoB100 (r=–0.769, –0.705 and –0.689); the level of free thyroxine (FT4) had a negative correlation with the levels of TC, LDL-C and ApoB100 (r=–0.728, –0.676 and –0.625) (all P<0.05). Conclusion: Thyroid dysfunction may cause blood lipid metabolic abnormity, which deserves attention in clinical practice.

      Abstract:As one of the life-threatening diseases in cardiovascular system, aortic dissection (AD) is an extremely dangerous condition with a complex pathogenesis. In recent years, the role of inflammatory reactions in the development of aortic dissection has increasingly attracted great attention, and many findings have shown that inflammatory reactions contribute greatly to the pathophysiology and outcomes of AD. In this article, the authors address the possible mechanisms for inflammatory reactions participating in the occurrence and development of AD, the relationship between markers of inflammation and diagnosis of AD, and the influence of inflammatory reactions on prognosis of different types of AD, as well as the current problems and future prospects.

    • Surgical treatment of abdominal aortic aneurysm associated with horseshoe kidney: essentials and difficulties

      2015, 24(6):870-841. DOI: 10.3978/j.issn.1005-6947.2015.06.021

      Abstract (221) HTML (0) PDF 1.14 M (570) Comment (0) Favorites

      Abstract:Abdominal aortic aneurysm (AAA) with concomitant horseshoe kidney (HSK) is a rare clinical entity. Special consideration to the abnormal anatomy of the kidney, such as the isthmus of the HSK straddling the aneurysm and the accessory renal arteries originating from the abdominal aorta, should be taken during its surgical treatment. Current treatment methods include open surgery (transabdominal or retroperitoneal), endovascular repair and hybrid surgery. But the indications and specific technical approach for those procedures remain inconclusive. In this paper, the authors present and analyze the essentials and difficulties in surgical treatment of this condition, so as to provide a reference for clinical practice.
