Perioperative complications of interventional therapy for lower extremity arteriosclerosis obliterans / 中华普通外科杂志

ABSTRACT

Objective To evaluate the prevention and management for the complications in interventional therapy for the lower extremity arteriosclerosis obliterans (ASO). Methods In this study 207 ASO cases received interventional therapy. The relationship between complication rates and different TASC type and the influence of diabetes mellitus (DM) with coronary heart disease (CHD) on critical organs complication rates was analyzed. Results The intervention succeeded in 190 cases. There was 17 failures, including 13 procedure failures and 4 deaths due to postoperative critical organ complications. Among the complications there were puncture site hemorrhage in 12, pseudoaneurysm in 4, alimentary tract hemorrhage in 2, arteriorrhexis in 6, cerebral infarction in 8, acute heart failure in 9, respiratory failure in 13, renal failure in 6, thrombosis in 5 and blue-toe syndrome in 1. The intraoperative complication rate of femoral-political type (39.84%, 51/128) was high than that of aorta-iliac type (18.99%, 15/79) (P< 0.05). Those critical organ complication rates of patients with DM and patients with DM&CHD were 27.66% (13/47)and 24.49% (12/49)respectively, they were higher than that of patients without (5%, 2/40) (P<0.05). Conclusions The high complication rates during interventional therapy of ASO were because of misoperation and complicated pathological type and together with DM and CHD. These rates could be decreased when we treated DM and CHD before operation and chosen a reasonable method and shorten the duration of operation.
