Peroperative proof of patency of microvascular anastomoses.

An experimental model is described for end-to-end and end-to-side anastomosis involving rabbit femoral vessels. In this experimental situation the ultimate test of patency is transection beyond the anastomosis. Against this the micro-electromagnetic flow probe has been evaluated using 17 rabbits and 24 procedures. Likewise the directional Doppler has been evaluated with 13 rabbits involving 22 procedures. The condition of the anastomosis could always be accurately assessed by the directional Doppler but not always by the electromagnetic flow probe.

The precise technique of end-to-side microvascular anastomosis with a suitable experimental model.

In order to perform extracranial to intracranial microrevascularisation a good end-to-side microvascular anastomosis technique is the first essential. The rabbit femoral vessels are similar in size to the human cortical branches of the middle meningeal artery and superficial temporal artery and an easy technique of end-to-side anastomosis of these vessels is described. This pays particular attention to proof of patency until the last stitch is applied. Assessment of patency in all three directions is checked by the directional Doppler or the electromagnetic flow probe.

The value of the electromagnetic flow probe in experimental and clinical microvascular anastomosis.

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.
