  • Title: Acute aortocaval fistula in association with ruptured aortic aneurysm.
    Author: Vohra R, Carrim A, Groome J, Leiberman DP.
    Journal: J R Coll Surg Edinb; 1991 Jun; 36(3):161-3. PubMed ID: 1920228.
    Abstract:
    Eight cases of aortocaval fistula are described. In all of them operation was performed with repair of the fistula and replacement of the aneurysm by a prosthetic graft. In seven cases the cause was rupture of an atherosclerotic aneurysm but one case followed rupture of a re-entrant dissecting aortic aneurysm. A fistula is most easily recognized by the sensation of a palpable thrill over the aorta during operation together with systemic venous congestion and a high central venous pressure before aortic clamps are applied. Diagnosis of the fistula before surgery or its recognition during operation and before opening the aorta usually leads to a successful outcome.
