Splenic Artery Embolization for Treatment of Iatrogenic Kasabach-Merritt Phenomenon Following Failed Endovascular Splenic Artery Aneurysm Repair

Abstract

Stent grafts are utilized to treat and exclude visceral arterial aneurysms while preserving flow through the vessel. Stent-associated thrombocytopenia is a rare complication not typically seen with modern stents. The following case describes the clinical presentation of stent kinking and consumptive coagulopathy. Stent-associated microangiopathic hemolytic anemia was inferred from protracted workup and exclusion of alternative diagnoses. Despite the risk of arterial puncture in the setting of profound thrombocytopenia, the patient was successfully treated with stent embolization with near immediate rebound in platelet count. This case report documents the presentation of rare stent-associated thrombocytopenia leading to challenging diagnostic evaluation and necessitating high-risk intervention.

Endovascular Coil Embolization of a Large Ruptured Splenic Artery Aneurysm: A Case Report

“…The versatility of endovascular repair is also evident in its application to complex and anomalous SAAs. Cases involving SAAs with anomalous origins or those associated with systemic conditions like lupus have been successfully managed using endovascular approaches [4,5]. This adaptability is crucial, considering the diverse presentations of SAAs.…”
