Abstract:
ObjectiveTo evaluate the value of transcranial Doppler (TCD) in pecutaneous transtuminl angioplasty and stenting (PTAS).MethodsThe index of hemodynamics, include mean peak flow velocity (Vm), systolic peak flow velocity (Vs), enddiastolic peak flow velocity (Vd), pulsatility index (Pi), resistance index (Ri) in 47 cases with the stenosis of the middle cerebral artery were investigated, while compared with that of intra arterial digital subtraction angiography (DSA). ResultsVs and Vm of 41 cases increased while the Pi reduced after operation, Ri had no change; Vs, Vm, Vd increased and Pi reduced with no reflow signal in 5 cases. Vs and Vm increased with Vd reduced in only 1 case. The accuracy rate with DSA in moderate or severe stenosis was 75% or 83% respectively. ConclusionTCD, as it's reliable, no-invasive, convenience and cheap, can play an important role in assessing the effect of PTAS in middle cerebral artery stenosis.
