[Surgical treatment of occlusive and stenosing lesions of brachiocephalic arteries].

The results of surgical treatment of patients with occlusive and stenosing lesions of brachiocephalic arteries implemented at Burdenko's Research Institute of Neurosurgery of the Russian Academy of Medical Sciences (RAMS) during 1999-2002 are described. A total of 164 operations were made in 128 patients. Different diagnostic methods and indications for various types of reconstructive and revascularization surgeries are under discussion.

[X-ray contrast filler for balloons at endovascular surgery (20 years of experience with original balloon filler)].

In 1984, the authors designed a X-ray contrast balloon filler polyacryl amide gel (PAAG) that has a polymerization rate of 1-3 min. PAAG has been used to fill over 5000 balloons for nearly 20 years. With this filler, recurrent anastomoses reduced by 1.

[Main anastomoses of external carotid artery branches with the beds of the internal carotid and the vertebral artery and a role of pharmacological tests in the determination of their functional value at tumor embolization].

In 21 patients with meningovascular tumors (meningiomas, angiofibromas, etc.), 53 vessels were tested during preoperative embolization of extracranial tumors. Two groups of drugs were superselectively intraarterially administered in turn--first barbiturates, such as thiopental sodium, 15-20 mg in 2 ml of sodium chloride solution, to detect anastomoses with cerebral vessels, then local anesthetics (lidocaine, 10-20 mg in 2 ml of sodium chloride solution, to reveal the vessels feeding cranial nerves.

[Experience with endovascular occlusion of cerebrovascular aneurysms by means of microspirals].

The paper summarizes the outcomes of endovascular treatment of 42 patients (19 males and 23 females) aged 24 to 68 years who had cerebrovascular aneurysms, 7 of them were operated on in the acute phase of subarachnoidal hemorrhage. There were small [n = 27 (61.4%)], large [n = 14 (31.
