Treatment of Radiation Induced Arterial Occlusion: Importance of Extraanatomic Approach: Case Reports:

Radiation injury is an uncommon but increasingly important cause of arterial insufficiency. Radiation-in duced vascular compromise can threaten limbs once thought salvaged by radiotherapy in the course of treating neoplasms. Two cases of la tent arterial occlusion secondary to radiotherapy are reported. The alter ation of tissue architecture surround ing this type of arterial injury requires a different approach to vas cular repair afforded only by ex traanatomic bypass grafting.
