Mycotic Pseudoaneurysm: Clinical Course, Management and Prognosis.

Pseudoaneurysm of vessels (most common in arteries), in general, happens when a blood vessel wall is damaged leading to leakage of blood and its collection in the surrounding tissue, essentially resulting in a false aneurysm. These false collections can be problematic and can develop in any location. However, their most common clinical presentation is in the femoral arteries. These manifest especially following an endovascular intervention. Here, we discuss a case of a 73-year-old male whose in-hospital course was complicated by the development and subsequent infection of a pseudoaneurysm after he was admitted for sepsis from a UTI. We further highlight the pathophysiology related to the formation of a pseudoaneurysm, and the mechanism of action behind various treatment modalities used. The clinical course and possible treatment options may vary. However, a robust combination of early surgical management alongside medical management seems to provide the best outcome.
