Extensive Arterial Dissection: A Rare Multivascular Emergency.

Aortic dissection is a life-threatening vascular emergency associated with high morbidity and mortality. Clinical manifestations might include severe chest pain to neurological deficits, depending on the arterial segments involved. Extensive dissections involving multiple aortic segments and branch vessel occlusions, such as the carotid arteries, are rare and pose unique diagnostic and therapeutic challenges. We describe the case of a 64-year-old male, an active smoker with obesity, who presented to the emergency department with altered consciousness. He was found to have an extensive aortic dissection involving the ascending, arch, descending, and abdominal aorta, as well as occlusion of the right carotid artery. An urgent combined cardiothoracic and vascular surgical approach was undertaken. Despite suffering an ischemic stroke, the patient recovered successfully after a comprehensive rehabilitation program. This case underscores the importance of early recognition and a multidisciplinary strategy in managing extensive aortic dissection with neurological compromise. It highlights the potential of innovative surgical techniques and tailored rehabilitation to optimize outcomes in these complex cases.
