Abstract:
Objective To evaluate the variation of the blood flow in anterolateral femoral head by ligating different amount of extracapsular arteries. Methods Thirty six hips of 18 mongrel puppies were divided into A、 B、 C、 D and E groups. In group A, only one peripheral artery was ligated randomly. In groups B, C, D,and E, 2, 3, 4, and 5 peripheral arteries were respectively ligated. The blood flow in anterolateral femoral head in 18 mongrel puppies was measured before and after the ligation of the arteries by using of Hydrogen clearance technique. Results 1) The average blood flow in anterolateral femoral head was (0.1397?0.0515) ml?min-1?ml-1. 2) The mean blood flow in the anterolateral femoral head was slightly decreased after one to two of the extracapsular main arteries were ligated but there was no statistical difference. However, the mean blood flow was decreased significantly after more than three arteries were ligated. Conclusion 1) Hydrogen clearance technique is a quite simple, economic and reliable method for estimation of blood flow perfusion in various tissue. 2) The efficiency of blood supply of the anterolateral femoral head in puppies depends at least upon three of the major extracapsular arteries.
