“…This rare vasculopathy predominantly affects the abdominal visceral arteries, but it can also involve cerebral, renal and epicardial coronary arteries. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] Individuals with abdominal SAM are usually middle-aged and elderly and the main clinical presentation is acute abdominal hemorrhage or intestinal ischemia consequent to arterial dissection and/or to arterial rupture secondary to loss of the media and aneurysm or pseudoaneurysm rupture. 1,3,5,7,8,17 However, some patients present with asymptomatic aneurysms.…”

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.

“…4) However, ECA aneurysms are considerably less common than intracranial aneurysms, which most often occur as a traumatic pseudoaneurysm of the anatomically vulnerable superior temporal artery. 9) In our case, the ECA aneurysm might have resulted from iatrogenic injury in the course of multiple interventional procedures for treatment of severe vasospasm.…”

A 30-year-old man presented with an aneurysm of the left posterior inferior cerebellar artery manifesting as subarachnoid hemorrhage and cerebellar infarction. Angiography demonstrated string-of-beads sign typical of fibromuscular dysplasia (FMD) in the extracranial carotid and vertebral arteries. The aneurysm and the parent artery were successfully embolized with Guglielmi detachable coils. Severe vasospasm developed 1 week after admission, and was treated several times by selective injection of vasodilator. A new aneurysm of the left external carotid artery became evident 1 month later, whereas only slight dilation had previously been apparent. This angiographic sequence demonstrated a new arterial dissection. Despite the possibility of damage to the artery during multiple catheterizations, arterial wall changes caused by FMD appear to have been primarily responsible. This case emphasizes the need for particular care in performing vascular interventional procedures in the presence of FMD.

“…In addition, given that the true aneurysms occur in younger patients, it must be assumed that there are other causes. According to some authors congenital defect of the vessel wall also has a role in the development of true aneurysms, as well as segmental arteriopathic amyloidosis (17) or non-specific temporal arteritis (5). Differentiation whether it is a true or pseudo aneurysms is only possible by histopathological analysis.…”

Aneurysms of the temporal superfi cial artery (TSA) are very rare clinical entity. From 1861 to the present day, is described less than 200 cases. e most common cause of these aneurysms is so called blunt head trauma but there are described many cases of iatrogenic aneurysms, very rarely, aneurysms arise spontaneously. We report a case of 17-yearold patient with spontaneously formatting aneurysm of TSA.ree months prior to admission, he noticed the existence of tumefaction localized frontotemporal on the right side. MSCT angiography of blood vessels of the scalp showed an aneurysm on the frontal branch of TSA diameter of 15 mm. e aneurysm was resected with uneventful postoperative course. PH fi ndings pointed to a true aneurysm. Treatment protocol for the aneurysms of the TSA include clinical monitoring, compression of the aneurysm, the injection of thrombin, endovascular treatment and surgical resection. Surgical resection has proven to be a safe and eff ective treatment modality and still is the method of choice.
