[A new variant of the popliteal artery compression syndrome].

The authors describe a new variant of the popliteal artery across the lateral head of the gastrocnemius muscle. Therefore a new more simple classification is proposed: type I-III. A further differentiation in subgroups as Ia, IIa according to Insua has no clinical value. A posterior approach to the popliteal artery gives a detailed view of the anatomic structures such as muscle and band origin. A medial incision should be chosen if crural reconstruction is expected.
