Replantation of the completely avulsed thumb using long arterial and venous grafts.

Long arterial and venous grafts (10-15 cm. in length) were used in the replantation of thumbs amputated by avulsion. All replanted parts survived and thrombosis requiring anastomotic revision did not occur in any of the cases. Based upon a consideration of different factors that may lead to the formation of thrombus in reconstructed vessels, a method is recommended for routine use in replantation of the thumb, with specific reference to avulsion injuries.
