## TL;DR

An 88-year-old woman with rare SIDSMA experienced hemorrhagic shock and was successfully treated with endovascular therapy.

## Contribution

This case report highlights a rare complication of SIDSMA leading to hemorrhagic shock and its successful endovascular treatment.

## Key findings

- SIDSMA was diagnosed via CT angiography in an 88-year-old woman.
- The patient progressed from acute abdominal symptoms to hemorrhagic shock.
- Endovascular treatment successfully managed the condition after fluid resuscitation.

## Abstract

Spontaneous isolated dissection of the superior mesenteric artery (SIDSMA) is a rare condition, particularly when complicated by hemorrhagic shock. This case report describes the discovery of SIDSMA in an 88-year-old woman through CT angiography. The patient initially presented with acute abdominal pain, nausea, and diarrhea, which later progressed to hemorrhagic shock. After fluid resuscitation, the patient underwent successful endovascular treatment.
