    Notes: Abstract. Popliteal artery entrapment (PAE) syndrome is an uncommon congenital anomaly seen in young adults causing ischemic symptoms in the lower extremities. It is the result of various types of anomalous relationships between the popliteal artery and the neighboring muscular structures. The purpose of this study was to define the role of MR imaging combined with MR angiography in the diagnosis of PAE cases. Four cases with segmental occlusion and medial displacement of popliteal artery in digital subtraction angiography (DSA) examinations were diagnosed as PAE syndrome by MR imaging and MR angiography. The DSA and MRA images are compared. All of the cases showed various degrees of abnormal intercondylar insertion of the medial head of the gastrocnemius muscle. The MR images showed detailed anatomy of the region revealing the cause of the arterial entrapment. Subclassification of the cases were done and fat tissue filling the normal localization of the muscle was evaluated. The DSA and MRA images demonstrated the length and localization of the occluded segment and collateral vascular developments equally. It is concluded that angiographic evaluation alone in PAE syndrome might result in overlooking the underlying cause of the arterial occlusion, which in turn leads to unsuccessful therapy procedures such as balloon angioplasty. Magnetic resonance imaging combined with MR angiography demonstrates both the vascular anatomy and the variations in the muscular structures in the popliteal fossa successfully, and this combination seems to be the most effective way of evaluating young adults with ischemic symptoms suggesting PAE syndrome.

    Reconstruction of the microtic external ear in adults using porous polyethylene implant (1996)

    Notes: Abstract Autogenous rib cartilage and many other materials have been used for external ear reconstruction. Although the most commonly used material is the former, harvesting, carving and shaping are problems. Recently, porous polyethylene implants have proved to be useful for ear reconstruction. Ten ear reconstructions were performed in adults using porous polyethylene implants over the last two years. The patients were treated in two stages. First, the material was implanted and at the second stage the ear was elevated and the lobule was transposed. Both stages were performed under local anesthesia. There were three exposures which were managed without implant removal. One infected implant was salvaged by irrigation with antibiotics. All reconstructions were accepted as pleasing by the patients.
