One-Stage Revascularization to the Ipsilateral Middle Cerebral Artery and Contralateral Anterior Cerebral Artery Territories.

BACKGROUND

Patients with multiple intracranial atherosclerotic stenoses often present with hemodynamic instability in 2 remote regions without a reciprocal vascular network. In this situation, revascularization to each region may be required.

METHODS

In this report, 2 patients who had coexisting unilateral middle cerebral artery (MCA) and contralateral anterior cerebral artery territory ischemia were treated by using ipsilateral superficial temporal artery (STA)-radial artery graft-contralateral A3 bypass and ipsilateral STA-MCA bypass in one stage.

RESULTS

Postoperatively, the bypass conduit was well established, and the patients' hemodynamic instability was improved.

CONCLUSIONS

In patients with severe hemodynamic instability in the remote unilateral MCA and contralateral anterior cerebral artery regions, as in our 2 cases, ipsilateral STA-MCA and ipsilateral STA-radial artery graft-contralateral A3 bypasses in one stage can be a treatment option.
