Abstract

Segmental arterial mediolysis is a rare disease characterized by idiopathic noninflammatory vasculopathy involving small to medium arteries. Here, we report a case of ruptured cerebral and abdominal aneurysms, which were successfully treated using emergency endovascular coil embolization. A 45-year-old male suffered subarachnoid hemorrhage caused by the rupture of the right vertebral artery dissecting aneurysm, which was treated using emergency endovascular coiling. Iatrogenic dissection of the left vertebral artery occurred during the procedure. A stent was placed, and antivasospasm therapy was initiated after operation. Eight days after admission, the patient experienced sudden hypovolemic shock because of an abdominal hemorrhage, which was diagnosed as the rupture of an aneurysm in the accessory middle colic artery and treated with urgent coil embolization. It is extremely rare for a subarachnoid and an abdominal hemorrhage to occur simultaneously during hospitalization. Here, owing to the vulnerability of the unaffected vertebral artery during the initial procedure, segmental arterial mediolysis was diagnosed.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.

Cajal Bodies & Gems

Cajal bodies or coiled bodies are dense foci of coilin protein. Gemini of Cajal bodies, or gems, are microscopically similar to Cajal bodies. It is believed that Cajal bodies play important roles in RNA processing while gems assist the Cajal bodies. Find the latest research on Cajal bodies and gems here.

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.
