The Role of TCD in Assessing Postoperative Collateral Development and Long-Term Clinical Outcome in Moyamoya Disease.

ABSTRACT:

Aims

To explore the role of transcranial Doppler (TCD) parameters after encephaloduroarteriosynangiosis (EDAS) to identify collateral development in moyamoya disease (MMD) and assess the relationship between these collateral formations and long-term postoperative cerebrovascular events.

Methods

A retrospective analysis of 91 MMD patients who underwent EDAS. Patients were categorized into rich or poor collateral groups based on postoperative angiography. TCD was used to monitor changes in hemodynamic parameters pre-and post-surgery. The association between clinical outcome, TCD parameters, and the degree of collateral development was investigated.

Outcomes

Ninety-one patients were assessed, with 45 (49.0%) exhibiting rich collaterals and 46 (51.0%) showing poor collate
