Case of Segmental Arterial Mediolysis

Area of Science:

• Vascular Medicine
• Interventional Radiology
• Gastroenterology

Background:

• Segmental arterial mediolysis (SAM) is a rare, non-inflammatory vascular disease.
• It primarily affects medium to large abdominal arteries.
• SAM can lead to severe complications like intra-abdominal hemorrhage.

Purpose of the Study:

• To report a case of Segmental arterial mediolysis (SAM) involving multiple abdominal arteries.
• To demonstrate the successful application of endovascular coil embolisation in managing a critical complication of SAM.

Main Methods:

• The study involved a patient diagnosed with SAM affecting the coeliac, splenic, renal, and gastroduodenal arteries.
• Endovascular coil embolisation was performed to treat a pseudoaneurysm in the gastroduodenal artery.

Main Results:

• The endovascular coil embolisation procedure was technically successful.
• The treatment effectively managed the bleeding pseudoaneurysm, resolving the acute complication.

Conclusions:

• Segmental arterial mediolysis (SAM) is a serious vascular condition requiring prompt management.
• Endovascular coil embolisation is a viable and effective treatment option for managing bleeding pseudoaneurysms secondary to SAM.
