OBJECTIVE: The natural history of penetrating @entity1066 of the iliac arteries (PUIA) has not been previously described. The potential for degeneration into pseudoanerysm and @entity397 are feared complications. It is hypothesized that PUIA, similar to their thoracic aortic counterparts, signal impending vascular catastrophe. METHODS: A search of computed tomography (CT) angiography reports for the words, "penetrating @entity1066 " was performed. @entity1 with PUIA who underwent CT imaging from October 2010 to August 2011 were identified. Their clinical course was followed through December 2014. If @entity1 with PUIA had additional vascular pathology that necessitated intervention, it was performed. A prospective and retrospective review of the imaging was performed when possible. Associated iliac diameter and @entity1066 dimensions were measured for @entity1 with repeat imaging (n  = 22). Demographic characteristics were compared for @entity1 who were identified as having penetrating @entity1066 of the abdominal aorta. Mann-Whitney U, Fisher exact, and Pearson correlation coefficient tests were performed for statistical analysis. RESULTS: The calculated incidence of PUIA for @entity1 who underwent CT imaging was 0.3%. The age at the time of diagnosis was 70.7     10.0  years and the cohort included 28 male @entity1 (82.3%). Median clinical and imaging follow-up was 42.0 (range, 1-82) months and 40.5 (range, 1-77) months. Most @entity1 had a history of @entity101 (82.4%), @entity407 (76.5%), and @entity286 use (70.6%). Twenty-one @entity1 (61.8%) had concomitant @entity439 not necessarily associated with the PUIA. Although no PUIA @entity397 occurred, the population was sick because seven @entity1 (20.6%) were deceased at the study end. Only one individual presented with symptoms that could possibly be attributed to their PUIA. Repeat imaging was performed for 22 @entity1 (64.7%). The calculated median iliac artery diameter growth rate through the PUIA was 0.1 (range, 0-4.1) mm/y. CONCLUSIONS: PUIA are generally slow-growing and are found incidentally. Most @entity1 with PUIA were in their eighth decade with a history of @entity101 and @entity286 use. @entity1 with PUIA frequently have concurrent @entity449 that requires intervention. The mortality for this population was high, but was not caused by @entity397 of a PUIA.  Diameter changes noted in the PUIA during follow-up did not suggest @entity1066 treatment would improve survival.
