Objective To compare the advantages and disadvantages between double Perclose ProGlide crossing suture and traditional suture for the closure of 20F or 22F access points so as to provide a basis for selecting appropriate approach to repair the puncture points in endovascular aortic repair. Methods Between June 2007 and May 2011, 103 patients (115 common femoral arteries) underwent endovascular aortic repair using sheaths of 20F or 22F (outer diameter); double Perclose ProGlide crossing suture was performed for closure of puncture sites in 57 cases (64 common femoral arteries) (double Perclose group) and traditional suture in 46 cases (51 common femoral arteries) (traditional group). There was no significant difference in age, gender, or disease duration between 2 groups (P gt; 0.05). Results The operation time, blood loss, and hospitalization days of double Perclose group were significantly better than those of traditional group (P lt; 0.05). Ecchymoma in inguinal region and lymphatic leakage occurred in 5 cases (5 common femoral arteries) and 2 cases (2 common femoral arteries) of double Perclose group respectively, in 2 cases (2 common femoral arteries) and 6 cases (8 common femoral arteries) of traditional group respectively; no significant difference was found in the rate of the early complication between double Perclose group and traditional group (7.8% vs. 15.7%, χ2=1.76, P=0.19). The technique success rate of double Perclose group was 96.9% (62/64), and was 100% (51/51) in traditional group, showing no significant difference (χ2=0.31, P=0.50). All patients were followed up, 2-19 months (mean, 15 months) in double Perclose group and 2-18 months (mean, 14 months) in traditional group. Pseudoaneurysm occurred in the puncture region at 3 months in 1 case (1 common femoral artery) of double Perclose group, and incision and suture therapy was performed; no arteriostenosis or pseudoaneurysm occurred in other cases; and the rate of mid-term complication was 1.6% (1/64) in double Perclose group and was 0 in traditional group, showing no significant difference (P=1.000). Conclusion Double Perclose ProGlide crossing suture has the same effectiveness to traditional surture in repairing the puncture point with 20F or 22F, but it is superior to traditional suture in reducing operation time, blood loss, and hospitalization days.
Objective To investigate the early effectiveness of total percutaneous endovascular aneurysm repair (TPEVAR) in treating asymptomatic abdominal aortic aneurysm (AAAA) by comparing with surgical femoral cutdown endovascular aneurysm repair (SFCEVAR). Methods Between January 2010 and May 2011, 41 cases of AAAA were treated with TPEVAR in 26 cases (TPEVAR group) and with SFCEVAR in 15 cases (SFCEVAR group). The maximum tumor diameter ranged from 3.5 to 9.2 cm (mean, 5.7 cm) in TPEVAR group, and ranged from 3.5 to 10.0 cm (mean, 6.9 cm) in SFCEVAR group. There was no significant difference in gender or age between 2 groups (P gt; 0.05). Results All patients underwent EVAR successfully. The patients were followed up 6-23 months (mean, 13.5 months). No significant difference was found in the outer diameters of the delivery system for main body and iliac leg, operation time, contrast media dosage, hospitalization days, or postoperative hospitalization days between 2 groups (P gt; 0.05). The patients of SFCEVAR group had more bleeding volume and longer ICU stay than patients of TPEVAR group (P lt; 0.05). The incidence of minor complication was 7.7% (2/26) in TPEVAR group and 33.3% (5/15) in SFCEVAR group, showing no significant difference between 2 group (χ2=4.42, P=0.08); the incidence of major complication in SFCEVAR group (20.0%, 3/15) was significantly higher than that in TPEVAR group (0) (χ2=5.61, P=0.02). Conclusion TPEVAR shows safer and more effective than SFCEVAR in treating AAAA.
ObjectiveTo evaluate the short-and long-term results of hybrid procedures in the treatment for aortic arch lesions. MethodsFrom October 2002 to March 2011, 28 patients with thoracic aortic aneurysms or dissections involving the aortic arch were treated with hybrid endovascular treatment in our center. Twenty-two males and 6 females were in the series. The mean age of the patients was 68 years old. Of 28 patients, 15 were atherosclerotic thoracic aortic aneurysms and 13 were thoracic aortic dissection. Follow-up protocol consisted of computed tomography (CT) angiograms or ultrasound was performed in 3, 6, and 12 months, and annually thereafter. The main goal was to evaluate the operative mortality, morbidity, and the longterm survival of these patients. ResultsHybrid procedures included 12 totalarch transpositions, 3 left common carotid artery (LCCA)left subclavian artery (LSA) bypass, 11 right common carotid artery (RCCA)LCCA-LSA bypass, 2 RCCA-LCCA bypass. The technical success rate was 92.9% (26/28). The complications occurred in 10 patients (35.7%). Operative mortality was 7.1% (2/28). The apoplexia rate was 7.1% (2/28). The time of followup was (36±3) months. The patency rates of 1-year, 3-year, and 5-year were 100%, 92.9% (26/28), and 85.7% (24/28), respectively. The survival rates of 1-year, 3-year, and 5-year were 89.3% (25/28), 71.4% (20/28), and 60.7% (17/28), respectively. ConclusionsThe short-and long-term results with hybrid procedures in the treatment for aortic arch diseases are satisfactory. Further reducing the complications is the key to increase the survival rate.
ObjectiveTo explore the effectiveness of thoracic endovascular aortic repair (TEVAR) for blunt thoracic aortic injury (BTAI) with hostile stent-graft proximal landing zone. MethodsA retrospective analysis was made on the clinical data of 13 patients with BTAI with hostile stent-graft proximal landing zone treated by TEVAR between December 2007 and December 2014. There were 10 males and 3 females with the mean age of 44 years (range, 24-64 years). The imaging examination indicated Stanford type B aortic dissection in 7 cases, pseudoaneurysm in 3 cases, aneurysm in 1 case, and penetrating ulcer in 2 cases. According to the partition method of thoracic aortic lesion by Mitchell, 8 cases underwent stent-graft with left subclavian artery (LSA) coverage, 3 underwent chimney stents for LSA, and 2 for left common carotid artery (LCCA). In 2 cases receiving chimney TEVAR involving LCCA, one underwent steel coils at the proximal segment of LSA to avoid type II endoleak and the other underwent in situ fenestration for endovascular reconstruction of LSA. ResultsAll TEVAR procedures were successfully performed. The mean operation time was 1.8 hours (range, 1-3 hours); the mean intraoperative blood loss was 120 mL (range, 30-200 mL); and the mean hospitalization time was 15 days (range, 7-37 days). No perioperative death and paraplegia occurred. The patients were followed up 3-30 months (mean, 18 months). Type I endoleak occurred in 1 case during operation and spontaneously healed within 6 months. Hematoma at brachial puncture site with median nerve compression symptoms occurred in 1 case at 3 weeks after operation; ultrasound examination showed brachial artery pseudoaneurysm and thrombosis, and satisfactory recovery was obtained after pseudoaneurysmectomy. No obvious chest pain, shortness of breath, left upper limbs weakness, numbness, and dizziness symptoms were observed. Imaging examination revealed that stentgraft and branched stent remained in stable condition. Meanwhile the blood flow was unobstructed. No lesions expanded and ruptured. No new death, bacterial infection, or other serious complications occurred. ConclusionAccording to Mitchell method, individualized plan may be the key to a promising result. More patients and further follow-up need to be included, studied, and observed.
