Angioplasty of the Superior Gluteal Artery in 34 Patients With Buttock Claudication

PurposeTo evaluate the performance of balloon angioplasty in the treatment of superior gluteal artery (SGA) lesions and the factors influencing results.MethodsBetween April 1997 and June 2012, 217 patients were treated for disabling buttock claudication. Of these, 34 (15%) consecutive patients (30 men; mean age 70±9 years) underwent angioplasty for 44 SGA origin lesions (5 bilateral): 24 stenoses and 20 occlusions. Standardized follow-up included clinical examination at 1 and 6 months and annually thereafter; angiography or computed tomography was obtained in cases of recurrent buttock claudication.ResultsAngioplasty was successful in 31 patients; 3 of the 20 SGA occlusions could not be recanalized. Twenty-four (59%) SGAs were treated without a stent (14 stenoses and 10 occlusions), while 10 stenoses and 7 occlusions were stented. There were no instances of SGA rupture, occlusion, or pseudoaneurysm. Two recanalizations were complicated with contrast extravasation in the buttock without consequence. Over a...
