3. Fig. 2
(A, B, C, and D). Sagittal image (A) of a major B-scan defect (heavy arrow). This intimal flap at the proximal anastomosis (B) demonstrated a focal increase in RA-PSV (3.1 m/sec). After revision RA-PSV (C) was decreased (1.1 m/sec) and follow-up angiogram (D) demonstrated a widely patent anastomosis. This patient was cured of hypertension.
