RESUMEN
We have studied the angiograms before and after arteriorrhaphy, which were performed on 20 cases at Busan National University Hospital. Among the cases, 15 were on upper extremity and 5 on lower extremity. The results obtained were as follows; 1. 8 cases among 19 on which angiogram were checked after arteriorrhaphy revealed the obstructive findings distal to injured vessels. 2. Necrosis did not occur following arteriorrhaphy for brachial artery, radial artery and ulnar artery and ulnar artery ruptures. On a cases of anterior tibial artery rupture, an A-K amputation was done due to progressive tissue necrosis. 3. Collateral circulations were very important pathway after brachial artery rupture and increased collateral circulations were showed on angiograms. 4. Localized thrombosis and hypertrophic vascular changes were found in 3 cases of re-exploration because of the obstruction after initial surgery.
