An Analysis of Complications of Brachial and Axillary Artery Punctures

To examine the complications of brachial and axillary artery punctures and the precautionary measures taken to lower their incidences. Retrospective analysis of 266 cases of brachial and axillary artery punctures was performed for angiography or angioplasty between January 2009 and December 2013 at the Department of Vascular Surgery, Xuanwu Hospital, Capital Medical University. Complications and their causes were assessed. Among all brachial artery punctures (n = 140), there were complications in 3.6 per cent of cases, including local hematoma in 1.4 per cent, pseudoaneurysm in 0.7 per cent, acute arterial thrombosis in 0.7 per cent, and median nerve injury in 0.7 per cent. Among all axillary artery punctures (n = 126), there were complications in 10.3 per cent of cases, including local hematoma in 4.8 per cent, pseudoaneurysm in 0.8 per cent, acute arterial thrombosis in 0.8 per cent, acute venous thrombosis in 0.8 per cent, and nerve injury in 3.2 per cent. The incidence of complications was significantly lower in brachial axillary artery puncture compared with axillary artery puncture (P < 0.05). The main factors associated with complications might be patient's vascular condition, perioperative medication, anatomical features of the artery, puncture site, successful rate of first-attempt puncture, and bandage strength. Incidence of complications of brachial and axillary artery punctures could be lowered by strengthening the choice of indications, improving the perioperative managements, being fully aware of the anatomical characteristics of the brachial and axillary arteries, and applying the standardized techniques of puncture and compression hemostasis.
