| Description | Aim: To present own experience with quantitative flow measurement (flowmetry) of parent and branching arteries during surgical treatment of cerebral aneurysms. Material and methods: Intraoperative flowmetry enables quantitative blood flow measurement in ml/min on the basis of integration of the ultrasound beam transit time difference. Between 1/2011 and 5/2013, quantitative blood flow measurement of parent and branching arteries was performed in 23 patients during cerebral aneurysm surgery. The mean age was 52.1 years (30-73). Incidental aneurysms were present in 19 cases; four patients had subarachnoid hemorrhage (Hunt-Hess I in two and Hunt-Hess II in two). Location: middle cerebral artery aneurysm - 16 patients, anterior communication artery aneurysms - four patients, posterior communication artery aneurysm - two patients, and distal anterior cerebral artery aneurysm - one patient. Size of the aneurysm: small (7 mm) in 10 patients, middle (8-14 mm) in nine patients, large (15-24 mm) in three patients and giant ( 25 mm) in one patient. Results: Thirty-day postoperative results: good recovery in 21 cases and moderate disability in two cases. No postoperative ischemia was recorded in the group of patients. A significant perioperative blood flow decline was recorded in four patients; this was due to vasospasm in two and the flow normalized after papaverin administration. Clip correction was necessary in two patients (8.7%) followed by normalization of the flow. Conclusions: Quantitative blood flow measurement contributes to improved perioperative safety in cerebral aneurysms surgery. Role of flowmetry is irreplaceable in detection of parent and45 branching artery stenosis/occlusion. |
