Ulnar Artery Thrombosis: A 6-Year Experience

ABSTRACT: Thrombosis of the ulnar artery can be a cause of significant morbidity. Most often  a consequence of blunt trauma to the hypothenar eminence of the hand, it may be attributable  to one traumatic event or to repetitive insults. Surgery is often required. We reviewed the  presentation and diagnosis of ulnar artery thrombosis and evaluated the effectiveness of  treatment by ulnar artery excision with interposition vein grafting. Retrospective chart analysis  from 1989 to 1995 at the Medical Center of Central Georgia showed that nine patients
(eight male, one female) were treated for ulnar artery thrombosis. Three had associated ulnar
artery aneurysms. Eight of the nine were treated with artery excision and interposition vein  grafting. Four also received stellate ganglion blocks before surgery. One was treated with stellate ganglion blocks alone. All patients had symptomatic relief and resolution of physical  findings. We conclude that ulnar artery thrombosis can be managed with ulnar artery excision and interposition vein grafting when conservative measures fail.
