Traumatic cerebral aneurysm after penetrating gunshot wound of the brain

A clinical case of traumatic cerebral artery aneurysm formation after a penetrating diametrical gunshot wound is presented. Based on data of primary primary and delayed cerebral angiography, intraoperative imaging of the arterial appearance, the evolution (emergence and growth) of a traumatic cerebral aneurysm within 14 days after wounding is traced. The clinical observation is of interest due to a combination of factors: the presence of an unrelated wound aneurysm in the same basin, available intraoperative images of the injured artery as the initial stage of traumatic aneurysm formation, and the possibility to trace angiographic stages of aneurysm formation. Two-stage surgical treatment was performed: removal of the wounding projectile and intravascular intervention (implantation of a flow-deflecting stent) at the level of the aneurysm. In the conclusion the clinical picture, radiological signs of penetrating cranial wounds characteristic for traumatic aneurysm formation, and their treatment tactics are discussed.
