Successful endovascular treatment for thrombotic in-stent iliac occlusion with in-house-devised optimo®-Like embolic protection system

Abstract

Introduction: In practical settings of endovascular treatment,wesometimes encounter difficulties in treating lesions with massive thrombi, which may cause distal thromboembolism. Case Presentation: We encountered a case of severe critical limb ischemia involving in-stent iliac occlusion with massive thrombi. We had to overcome the critical issue of how to treat the massive thrombi in the iliac artery while avoiding thromboembolism. Therefore, we devised a very simple but possibly very useful protection system without any special devices based on the concept of the Optimo® balloon-tipped occlusion catheter. Conclusions: Although various endovascular treatment (EVT) devices and techniques have since been developed, little tips and tricks during EVT procedures are sometimes markedly useful.
