Popliteal vascular compression in a normal population

High-Resolution HLA-A Typing in Normal Iranian Population

Background: Human leukocyte antigen (HLA) gene is a highly polymorphic region. HLA typing is required to match patients and donors for transplantation; therefore, development of HLA registries is necessary for finding HLA match donors. HLA system is highly informative, and numerous studies have been conducted on HLA allele distribution in different populations. Methods: In this study,...

Popliteal cyst rupture in normal knee joints.

Vascular claudication in a young patient: popliteal entrapment syndrome.

Popliteal artery entrapment syndrome is an important, albeit infrequent, cause of severe disability among young adults and athletes with anomalous anatomic relationships of the musculotendinous structures surrounding the popliteal artery. We report a case where duplex ultrasonography and dynamic magnetic resonance arteriography was used to diagnose popliteal artery entrapment. We used a posteri...

Distal sciatic nerve compression by a popliteal artery aneurysm.

A 77-year-old man developed progressive sensory and motor symptoms in the right lower leg. Examination showed neurological deficits in the distribution of the right tibial and common peroneal nerves. Swellings in both popliteal fossae were palpated. Investigation showed these to be large thrombosed aneurysms. On surgical examination on the right, the aneurysm was found to be compressing the dis...

Intra-vascular leiomyoma of the popliteal vein.

A large mass in the popliteal fossa was found to be a leiomyoma of the popliteal vein with portions of tumour both inside and outside the vein. This is only the second recorded case of a benign smooth muscle tumour of a peripheral vein.
