Case Study: Spontaneous Rupture of an Internal Thoracic Artery Aneurysm - A Rare and Critical Emergency with Treatment Challenges

1

Internal thoracic artery aneurysms are rare and often asymptomatic until they rupture, leading to life-threatening conditions.
2

A 42-year-old woman presented with acute chest pain and was diagnosed with a ruptured left ITA pseudoaneurysm via CTA.
3

Emergency transcatheter arterial embolization successfully achieved hemostasis, followed by ultrasound-guided chest tube drainage.
4

The patient recovered without complications and was discharged 14 days post-operation, highlighting effective management.
5

This case emphasizes the importance of CTA in diagnosing ruptured ITA aneurysms and the role of endovascular therapy.
