“…1) Multiple aneurysms and wall irregularity have been described as the primary characteristics of SAM. 7) In the present case, histopathology showed that chronic inflammatory cells, such as lymphocytes and plasma cells, were sparsely present in the adventitia, and EVG staining revealed fragmentation and a decrease of elastic fibers in the tunica media. Honestly speaking, we expected to confirm SAM, but the histopathology did not reveal SAM, atherosclerosis, and infection but for the fragmentation and degeneration of elastic fibers.…”

Middle colic artery aneurysms are rare and most have been reported with rupture or symptom. We report the successful elective treatment of a middle colic artery aneurysm without symptom, which is very rare. It failed to perform transcatheter arterial embolization for anatomical reasons, and, thus, the patient, a 77-year-old man, underwent surgical resection in spite of a history of laparotomy. Although a common cause of middle colic artery aneurysms is segmental arterial mediolysis, the present pathological findings indicated that fragmented or degenerated elastic fibers may also play an important role like aortic aneurysms.

“…14 From this etiology, this disease is also called "segmental mediolytic arteriopathy," but now the name "SAM" is the most frequently used. According to a review of 20 cases of SAM involving abdominal splanchnic arteries by Takagi et al, 15 SMA occurs in middle-aged to elderly people (range, 39-87 years) of both sexes, usually involves more than one visceral artery, and most frequently, branches of the celiac axis. The current case was compatible with these cases.…”

Middle-colic artery aneurysm associated with segmental arterial mediolysis, successfully managed by transcatheter arterial embolization: Report of a case

et al. 2009

An aneurysm of the middle-colic artery, associated with segmental arterial mediolysis (SAM), is a rare condition. This report describes a case of a middle-colic artery aneurysm that was associated with SAM. A 57-year-old man was admitted to our hospital because of severe abdominal pain. A rupture of a middle-colic artery aneurysm was diagnosed by computed tomography, and angiography showed that it may have been associated with SAM. The ruptured aneurysm was successfully treated with transcatheter arterial embolization. Transcatheter arterial embolization might be one of the best treatments for such a complicated aneurysm occurring in a visceral artery.

“…Segmental arterial mediolysis is a rare vascular disease characterized by a lytic process of the media, leading to formation of arterial gaps and aneurysms, arterial dissection and thrombosis 1,2 . The disease is more frequent in middle‐aged and elderly patients and usually affects abdominal muscular arteries 1,3–6 . The most common clinical presentation is sudden cardiovascular collapse after aneurysm rupture and intra‐abdominal hemorrhage and/or acute abdomen consequent to the bowel ischemia due to arterial dissection or thrombosis 1–3,7 , 8 .…”

Bilateral extensive cerebral infarction and mesenteric ischemia associated with segmental arterial mediolysis in two young women

Segmental arterial mediolysis (SAM) is a rare non-atherosclerotic non-inflammatory vascular disease that affects mainly muscular arteries of the splanchnic and cerebral territories. Reported herein are two cases of SAM in young women with fatal outcome. One of the patients had an atypical form of the disease, which primarily affected small intestinal submucosal and subserosal arteries, and resulted in acute mesenteric ischemia. The other had bilateral brain infarction with SAM of internal carotid arteries (ICA). Pathological examination of both cases did not reveal the cause of blood flow disturbance: large mesenteric branches of the former and ICA of the latter were free of either dissection or thrombosis; in addition, small intestinal arteries of the first patient did not show signs of vasculitis. These findings suggest that unusual pathways of arterial occlusion and dissection may occur in the context of SAM.
