[Endovascular embolization as a stage of preoperative preparation for improving surgical treatment of patients with inverted papilloma - a retrospective case series analysis. A clinical example of simultaneous endovascular embolization using navigation under the control of flat-detector computed tomography on a robotic angiographic complex and removal of an inverted papilloma in a hybrid operating room].

Unlabelled: Inverted papilloma (IP) is a sinonasal epithelial tumor that originates from Schneiderian membrane. A number of cellular factors associated with angiogenesis are involved in growth of IP, and causes an increased bleeding of the tumor. The main treatment is surgical removal of sinonasal papilloma.

[Otohematoma as manifestation of auricular arteriovenous malformation].

Arteriovenous malformation (AVM, arteriovenous dysplasia) is one of the variants of congenital vascular defects formed as a result of a defect in the development of the arterial and venous systems during ontogenesis with the formation of direct messages between vessels of different diameters. In this regard, high-speed shunting of blood from the arterial part of the vascular system to the venous through fistulas of various calibers occurs. This disease is characterized by a variety of clinical manifestations.
