Catheter-Directed Thrombolysis for Acute Superior Mesenteric Artery Occlusion: A Case Report

Acute mesenteric ischemia (AMI) is the sudden onset of small intestinal hypoperfusion, commonly due to thromboembolic obstruction of mesenteric vessels. Due to nonspecific symptoms at presentation, diagnosis can often be delayed until the condition rapidly progresses. Additionally, these factors likely contribute to AMI's high mortality rate, highlighting the importance of early diagnosis and intervention. Traditionally, AMI is managed with open abdominal surgery (e.g., embolectomy, bowel resection). However, alternative treatment methods have evolved, including endovascular techniques such as thrombolysis, which offer targeted therapy while preserving bowel integrity. The following case presents the management of a patient with mild mesenteric ischemia treated with the lesser-utilized catheter-directed thrombolysis.
