ABSTRACT

Objective Compared with the effect of thromboembolectomy assisted with intraoperative digital subtraction angiography (DSA) and traditional method,evaluate the value of intraoperative DSA on surgical procedures for acute lower limb arterial embolism. Methods Sixeight cases of traditional thromboembolectomy to take on the operation (group A) and 72 cases under the DSA operation (group B)were analyzed during January 2005 to December 2009, Comparing two sets of operation (time, the amount of bleeding and the ankle brachial index changes before and after the surgery , amputations rate). Results The operation time of group B [(76 ±17) min] was less than that of group A [(95 ± 22) min, t =5. 736, P ＜ 0. 01] ; the amount of bleeding of group B [(83 ± 35 ) ml] was significantly less than group A [(102 ± 58 ) ml, t = 2. 362, P ＜ 0. 05]; The difference of ABI in group B after the operation than before (0. 32 ±0. 08) than that in group A(0. 25 ±0. 12) had remarkably improved ( t =2. 33, P ＜0. 05) ;there were 8 patient amputations in group A and 2 in group B ( u = 2. 06 , P＜ 0. 05 ); there were 2 patients died in group A and one in group B ( P ＞ 0.05 ). Conclusion Thromboembolectomy assisted with DSA can be accurate assessment of the arteries embolism position, elevate the success rate in the operation ,reduce the rate of amputation saws.
