摘要
Background There has been a trend towards favouring endovascular repair for much acute aortic pathology. We undertook a review of the literature to determine if an endovascular approach could complement the traditional treatment of aortocaval fistula (ACF), a rare complication of abdominal aortic aneurysm. Methods A literature search was undertaken on PubMed using appropriate search terms. Case series and reviews reporting presentation, diagnosis and operative management (open and endovascular techniques) of ACF were selected and discussed. Results Open surgical treatment of ACF has an associated morbidity and mortality mainly from excessive blood loss. Open repair mortality rates are reported around 30%, but some centres report far lower rates based on preoperative diagnosis of the ACF. These rates appear to be reduced when using endovascular repair in selected cases, with success rates of up to 96%. Reiteration of the importance of diagnosis of ACF preoperatively was the common denominator with both open and endovascular repair. Conclusions Endovascular exclusion appears to be an efficacious means of treating ACF and averting the significant blood loss commonly encountered in conventional repair of these lesions. However, some reviews have suggested equal success with open repair. There is limited available published literature on ACF management and outcome, and likely reporting bias attached to both open and endovascular results that are published. With a randomized controlled trial unlikely to occur, a prospective registry may provide better outcome data.
