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.
