Background: Very small intracranial aneurysms, generally considered to be those 3 mm in diameter or smaller, pose particular technical challenges for endovascular surgeons. For this reason, very small aneurysms have been excluded from many relevant studies. The aim of our research was to establish the risk factors for the occurrence of stroke complications after endovascular embolization of ruptured and unruptured small intracranial aneurysms. Methods: During the period of 2009–2023, our team performed endovascular embolizations of intracranial aneurysms in 1567 patients across four different centers within the territory of Serbia and Montenegro. Within the total number of patients mentioned, aneurysms of less than 4 mm were treated 185 times, with 119 ruptured and 66 unruptured. Results: In the group of 119 patients with ruptured small intracranial aneurysms, 19 (16%) patients had ischemia after the endovascular treatment, 6 (5%) patients had minor neurological deficits, while 13 (10.9%) patients had major neurological deficits, of which 6 (5%) patients died. In the group of 66 patients with unruptured small intracranial aneurysms, 7 (10.6%) patients had ischemia after the endovascular treatment, 5 (7.6%) patients had minor neurological deficits, and 2 (3.03%) had major neurological deficits. Multivariate binary logistic regression showed that the risk factors for the occurrence of ischemia were the patient’s age, smoking and alcohol consumption. The type of endovascular treatment used also had a statistically significant effect on the development of ischemia. Conclusions: Understanding the influence of possible risk factors for the occurrence of ischemic insult after embolization of small intracranial aneurysms is of great importance. By recognizing them, periprocedural complications can be reduced to a minimum. © 2024 by the authors.

Aneurysms of the temporal superficial artery (TSA) are very rare clinical entity. From 1861 to the present day, is described less than 200 cases. The 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. Three 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. The aneurysm was resected with uneventful postoperative course. PH findings 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 effective treatment modality and still is the method of choice. © 2019, University of Kragujevac, Faculty of Science. All rights reserved.
