Abstract
Objective To assess CT angiography applied in clinical diagnosis of closed vascular injury.Methods A retrospective analysis was conducted to investigate the 24 cases of closed vascular injury who had been diagnosed by CT angiography from July 2005 to September 2007 in our hospital.Results CT angiography could accurately determinate the severity and location of closed arterial rupture and collateral circulation conditions.It revealed arterial occlusion in 16 cases, intra-luminal defects in 6 cases, and Pseudo-aneurysm in 2 cases.Surgical explorations for 20 patients found complete rupture of artery in 6 cases, incomplete rupture in 9 cases, endomembrane injury in 5 cases, and thrombosis in 4 cases.Of them, 12 cases received end-to-end anastomosis, 4 cases primary repair, and 4 cases saphenous vein transplantation.The postoperative blood circulation was normal.No functional abnormality was found in the followed-up for the 4 cases who had undergone conservative therapy due to fine collateral circulation.Conclusion CT angiography is valuable in diagnosing vascular injury and should be indicated for patients with suspicious vascular injury.
