# Ruptured isolated spinal artery aneurysms: a rare manifestation of an arterial dissecting disease

## TL;DR

This paper presents two cases of ruptured spinal artery aneurysms and reviews their rare condition and treatment approaches.

## Contribution

The paper contributes two clinical cases of ruptured ISAAs and a literature review on their management and pathophysiology.

## Key findings

- Two cases of ruptured posterior spinal artery aneurysms were successfully treated with surgery and embolization.
- Literature review highlights the unclear pathophysiology and non-standardized treatment of ISAAs.
- The paper emphasizes the rarity and challenges in managing isolated spinal artery aneurysms.

## Abstract

Isolated spinal artery aneurysms (ISAAs) are a rare cause of intracranial and spinal hemorrhages with unclear pathophysiology and natural history and non-standardized management strategies. We hereby present two cases of ruptured ISAAs of posterior spinal arteries treated with open surgery and embolization, respectively. Case presentations are followed by a comprehensive literature review on ISAA pathophysiology, natural history, and management strategies.
