[Pressure in intracranial saccular aneurysms in the presence of hypotension].
The pressure in saccular aneurysms of various localizations was studied in 6 patients during neurosurgical operations. The systolic, diastolic, mean, and pulse pressure in aneurysms with a wide neck corresponded to systemic pressure; in aneurysms with a narrow neck (3 patients) they were lower. In occlusion of the carotid artery on the neck, the pressure in the anurysms decreased. Pulsations disappeared in 3 patients. Fourteen patients with aneurysm of the internal carotid artery were followed-up for 2--17 years, after ligation of the carotid artery on the neck. There were no recurrent hemorrhages. Despite the clinical effect, however, due to possible complications this operation has limited indications (subclinoid aneurysms, refusal of patients to undergo intracranial operations).
