Iliac anatomy and the incidence of adjunctive maneuvers during XXXX repair.

PURPOSE: Challenging iliac anatomy remains an important issue during @entity439 repair (EVAR), and it is known that the length of the common iliac artery (CIA) is shorter in Asians than in Western groups. We analyzed both the iliac anatomy and the incidence of adjunctive maneuvers to overcome iliac artery-related difficulties during EVAR. METHODS: Seventy-four EVARs were performed for @entity1028 between January 2010 and March 2013. @entity1 demographic data, iliac anatomical characteristics (presence of @entity1029 , iliac artery diameter and length, and iliac tortuosity), and adjunctive iliac artery maneuvers were reviewed retrospectively. RESULTS: Mean CIA length was 52.8 mm (range, 6.6-98.0 mm) on the right and 56.3 mm (range, 0-94.8 mm) on the left. CIA length was >= 20 mm, except in one @entity1 with bilateral short CIAs. Forty @entity1 (54%) had a CIA @entity439 , and 18 had @entity439 on both sides. Iliac adjunctive procedures were performed in 38 @entity1 (51%) as follows: 23 internal iliac artery (IIA) embolizations or ligations, seven IIA revascularizations, 16 external iliac artery (EIA) balloon angioplasties or stenting, one EIA patch angioplasty, one EIA interposition, two femoral endarterectomies with patch angioplasty, and nine femoro-femoral bypasses after EVAR with an aorto-uni-iliac device. Technical success for the adjunctive iliac procedures was achieved in all @entity1 . CONCLUSION: Short CIA length was uncommon. Although many @entity1 had access-related difficulties, most were overcome by an endovascular or hybrid technique. Liberal use of iliac adjunctive procedures can facilitate EVAR.
