“…1, 2, 8-12 Reported operative mortality rates with elective open and endovascular repair are 3-6% and 0-1%, respectively. 1-4, 6, 9, 13, 14 However, the majority of these studies are from single institutions with small sample sizes The purpose of this national study is to identify epidemiologic trends in management and mortality for isolated iliac artery aneurysm and to evaluate the impact of the introduction of endovascular iliac aneurysm repair (EVIR) in the United States.…”

Objective Isolated Iliac artery aneurysms are rare, but potentially fatal. The impact of recent trends in the utilization of endovascular iliac aneurysm repair (EVIR) on isolated iliac artery aneurysm-associated mortality is unknown. Methods We identified all patients with a primary diagnosis of iliac artery aneurysm in the NIS from 1988 to 2011. We examined trends in management (open vs. EVIR, elective and urgent) and overall isolated iliac artery aneurysm related deaths (with or without repair). We compared in-hospital mortality and complications for the subgroup of patients undergoing elective open and EVIR from 2000-2011. Results We identified 33,161 patients undergoing isolated iliac artery aneurysm repair from 1988-2011: of which there were 9,016 EVIR and 4,933 open elective repairs from 2000-2011. Total repairs increased after introduction of EVIR from 28 to 71 per 10M US population (P<.001). EVIR surpassed open repair in 2003. Total isolated iliac artery aneurysm-related deaths, due to rupture or elective repair, decreased after the introduction of EVIR (4.4 to 2.3 per 10M US population, P<.001). However, urgent admissions have not decreased over this time period (15 to 15 procedures per 10M US population, P=0.30). Among elective repairs after 2000, EVIR patients were older (72.4 vs. 69.4 years, P=0.002) and were more likely to have a history of prior MI (14.0% vs. 11.3%, P<.001) and renal failure (7.2% vs. 3.6%, P<.001). Open repair had significantly higher in-hospital mortality (1.8% vs. 0.5%, P<0.001) and complications (17.9% vs. 6.7%, P<0.001), and a longer length of stay (6.7 vs. 2.3 days, P<0.001). Conclusions Treatment of isolated iliac artery aneurysm has increased since the introduction of EVIR and is associated with lower perioperative mortality, despite a higher burden of comorbid illness. Decreasing iliac artery aneurysm-attributable in-hospital deaths are likely related primarily to lower elective mortality with EVIR rather than rupture prevention.

“…The mid-term (36 months) primary graft patency rates in the open group and the EVIAR group were 100% and 95.6%-97%, respectively. In addition, the midterm (36 months) secondary intervention in the 2 groups was 0% and 11%-14%, respectively [28][29][30][31][32][33] . Endovascular repair for IIAA is safe and has similar intermediate-term outcomes to open repair.…”

“…However, minimally invasive procedures such as percutaneous thrombin injection and endovascular treatment by embolisation and stent-graft are increasingly used for the treatment of these lesions 2 3. US-guided compression, previously used in the management of some cases, has now generally been replaced by other more effective and practical techniques.…”

Pseudoaneurysms of the iliac arteries are extremely rare and can complicate trauma, surgical or interventional procedures. We report a case of pseudoaneurysm arising from the common iliac artery in a 37-year-old man which presented as a paravertebral collection. As the MRI appearance mimicked spondylodiscitis, a CT guided biopsy was requested. However, the presence of a signal void centre guided the radiologist to the correct diagnosis, which was later confirmed on contrast-enhanced CT. Following unsuccessful treatment by percutaneous thrombin injection, open surgery was performed which revealed a leaking aneurysm associated with a huge retroperitoneal haematoma. We present this case to highlight the importance of considering vascular lesions as a differential diagnosis in patients presenting with a mass or pressure symptoms in different parts of the body. Misdiagnosing such lesions as soft tissue tumours or abscesses may result in serious consequences.
