| Abstract | Background: Human immunodeficiency virus (HIV) is a multisystem disease and is associated with vascular complications including aneurysm formation. HIV-associated aneurysms are well documented and may present in unusual locations with concerning features. However, the literature regarding aneurysms in HIV-positive patients is limited to case series with limited data regarding aneurysm patterns. Furthermore, several small series have documented poor outcomes with surgical repair. Thus, our aim was to investigate the characteristics, patterns, and repair of aneurysms in HIV-positive patients in a multicenter study. Methods: All patients with a diagnosis of aneurysms and HIV were retrospectively identified from 2013 to 2018 across 2 institutions. Comorbidities, HIV-related characteristics, aneurysm characteristics, and repair were reviewed. Results: There were a total of 104 HIV-positive patients with 129 aneurysms. The mean age at the time of diagnosis was 57.7 ± 10.3 years, 80.8% of patients were male, and 32.0% had a history of acquired immunodeficiency syndrome. The average time from HIV diagnosis to aneurysm diagnosis was 14.1 ± 10.1 years. There were 53 (41.1%) ascending aortic, 25 (19.4%) abdominal aortic, 14 (10.9%) cerebral artery aneurysms, 13 (10.1%) descending thoracic, 9 (7.0%) iliac, 6 (4.7%) femoropopliteal, 4 (3.1%) visceral, 3 (2.9%) axillosubclavian, 1 (0.8%) carotid, and 1 (0.8%) coronary artery aneurysms. There were 23 (22.1%) patients with aneurysms in multiple vascular beds, 10 (9.6%) saccular aneurysms, and 1 (0.8%) inflammatory aneurysm. There were 7 ruptures (cerebral, descending thoracic, and iliac), 3 type A dissections (ascending aorta), and 1 thrombosis (popliteal). There were 26 (25.0%) patients who underwent surgical repair. This included 8 endovascular aneurysm repairs for abdominal aortic aneurysms, 6 endovascular coiling, clipping, and stent procedures for cerebral aneurysms, 4 open ascending aorta repairs, 2 bypasses for popliteal artery aneurysms, 2 endovascular stents for axillosubclavian artery aneurysms, 1 open descending aortic aneurysm repair, 1 endovascular aneurysm repair for an iliac aneurysm, 1 endovascular coiling for a renal artery aneurysm, and 1 open repair of a femoral artery aneurysm. Perioperative complications were common at 46.2%, although mortality was low at 3.8%. Conclusions: Although aneurysms were widespread, most HIV-positive patients had large vessel aneurysms in this study. There was a high prevalence of saccular and multiple aneurysms, and repair was associated with low rates of mortality despite high rates of complications. Additional studies are necessary to characterize this rare entity. |
