| Abstract |
|
Direct pressure monitoring by means of an intra-arterial cannula has been considered benefit for assesment of the critically ill patients, safe conduct of controlled hypotension and obtaining arterial samples for blood gas analysis. Cannulation of the radial artery is commonly used, but in neurosurgical operation the upper part of the body is usually nut easily accessible to the anesthetist and this may lead to increase the frequency of dorsalis pedis arterial cannulation. Recently we have experienced the undesirable episode of toe amputation resulting from gangrene following dorsalis pedis cannulation in 62 year old female neurosurgical patient. Femoral angiography performed on the post-operative 27th day showed that neraly complete obstruction of the posterior tibial artery at the level of ankle joint, and progressive tapering of the peroneal artery blanches below the ankle joint. We suppose that dorsalis pedis arterial thrombosis and posterior tibial arterial occulusion would seem to be a contributing factor of foot gangrene. |
