Endovascular retrieval of an entrapped balloon in a tibial artery

Abstract

Balloon entrapment is a rare complication of angioplasty in calcified or recalcitrant lesions. A 65-year-old man with chronic limb-threatening ischemia underwent balloon angioplasty of his heavily calcified tibial arteries with a low-profile, tapered, compliant balloon. The balloon became entrapped within the posterior tibial artery and required multiple endovascular maneuvers to deflate and separate the balloon from the calcified arterial wall. This case report describes several adjunctive techniques for retrieval of an entrapped balloon in small, calcified arteries before consideration of surgical removal. These techniques allow for minimally invasive retrieval and continuation of endovascular treatment thereafter.
