The Gould Statham Blood Flowmeter Model SP 2204 has been used to assess microanastomosis in 25 superficial femoral arteries of rabbits. When a pulsatile wave form has been achieved this correlates with a satisfactory anastomosis and vice versa. The digital read out of estimated volume flow past the anastomosis made by this instrument will need further evaluation. We are persisting with the electromagnetic flow probe in the assessment of our clinical microvascular anastomoses at operation. Images Fig. 1. Fig. 2.
