Carotid Artery Aneurysm-Induced Mediastinal Hematoma Leading to Airway Compression-A Rare Complication of Internal Jugular Vein Puncture.

Abstract

Carotid artery puncture is a common complication of internal jugular vein (IJV) catheterization. However, there are few reports about an aneurysm from the carotid artery that can develop into an occult mediastinal hematoma, leading to airway compression. In this case study, we present the case of a 71-year-old male who experienced an aneurysm and delayed mediastinal hematoma, ultimately resulting in airway compression after right jugular line insertion. Our findings highlight the importance of not only addressing local hematoma formation at the puncture site promptly, but also recognizing the potential for aneurysm extension into the mediastinum and the formation of an occult hematoma, which can lead to airway compression. Additionally, we provide a summary of landmark technique precautions that can help reduce the occurrence of such severe complications.
