Newer developments of extra-anatomic bypass

We have analyzed our eight year experience with more than 200 instances of extra-anatomic bypass and have made certain observations. Extra-anatomic bypass provides an acceptable alternative to extensive direct intra-abdominal and intrathoracic vascular reconstructive procedures. This is particularly true in high risk patients and in the presence of infection. While axillobifemoral bypass is widely known and used, other types of extra-anatomic bypass are emphasized. These are axillary-axillary, axillopopliteal, axillotibial and axillofemoral bypass under local anesthesia. Technical factors, such as the type of graft, the course of the bypass and ancillary techniques to improve the long term patency, are also discussed herein.
