Complications of iliac artery stent deployment

Abstract

Limb-threatening and life-threatening complications can be associated with iliac artery stent deployment. Stented iliac artery primary patency rates are affected by distal atherosclerotic occlusive disease and the position of the deployed stent within the iliac system. Stent reconstruction of severe iliac artery occlusive disease is feasible but should be thoughtfully selected.

Common femoral artery occlusive disease: Contemporary results following surgical endarterectomy

“…1,8 More recently, there have been reports of successful stent placements for disease in the CFA. 9,10 Most surgeons believe, however, that the potential problems of placing a stent in the CFA, including risk of stent fracture and intimal hyperplasia, 11,12 possible need to sacrifice collaterals provided by the profunda, and potential compromise in future surgical options in patients who often present with multilevel disease, outweigh the presumed advantages of an endovascular approach. In addition to PTA and stent placement, other modalities such as cryoplasty and atherectomy are being considered for treatment of occlusive disease in the CFA.…”

Venous stenting across the inguinal ligament

“…Stenting of arteries across moving joints, for example, is not recommended because of damage to the stents and more frequent development of intimal hyperplasia resulting in poorer patency. [5][6][7] There is a fear that this would also apply to venous stenting. Several factors affecting stent-outcome have been analyzed and reported in previous studies.…”

Two-Year Primary Patency Rates After Aortoiliac Occlusive Disease Endovascular Treatment

“…In the present study, we had no cases of either minor or major complications; therefore, we are unable to make any comparison between complication rates of angioplasty alone and angioplasty with stenting or between self-expandable and balloon expandable stents. Current literature suggests higher complications in iliac stenting (4% -19%) (20)(21)(22) compared to angioplasty alone (3% -7.9%) (23,24). In a study by Benetis et al in 2016, on the results of endovascular stenting between TASC II subtypes, the overall complication was reported to be 7.4% (25).…”
