title: [Application of intraoperative microvascular dopplerography in surgical treatment of arterial aneurysm of the brain].
abstract: The possibilities and results of the intraoperative microvascular dopplerography application in microsurgical exclusion of the brain arterial aneurysm (BAA) were estimated. The investigation was conducted during operative intervention in 30 patients, suffering hemorrhagic type of the brain acute blood flow disorder as a consequence of the BAA rupture. In an acute period (the first-14th day) 23 patients were operated, in the early restoration period (after 30th day)--7. Intraoperative express estimation of the blood flow have permitted to diagnose and to correct timely some typical technical complications, in particular, noncomplete BAA exclusion from the blood flow, the arterial lumen, containing the clipped aneurysm, stenosing; to reveal the arterial segments vasospasm objectively in the patients, operated on in an acute period of hemorrhage, and to diagnose a reactive spasm during manipulations on the arteries. All the patients, operated on in the early restoration period and 82.6% of patients, operated on in an acute period of subarachnoidal hemorrhage, have had reconvalesced. Application of the microvascular dopplerography secures objectivization, simplifies intraoperative estimation of the BAA radicality and the according arterial segments passability in the operative intervention zone, what promotes reduction of the ischemic complications rate and positively impacts the results of treatment.
