Síndrome de atrapamiento poplíteo / Popliteal entrapment syndrome

El síndrome del atrapamiento de la arteria poplítea, es una entidad nosológica no muy frecuente que afecta no solo a la arteria,sino también el componente venoso y nervioso de los segmentos situados a nivel del hueco poplíteo. Es una patología originada porla compresión de estas estructuras por elementos musculoesqueléticos situados en esta región anatómica que pueden ocasionar unasintomatología mas o menos intensa por la lesión de las estructuras que se comprimen. Existen diferentes formas anatómicas loque soporta una clasificación morfológica. Es preciso realizar el diagnostico diferencial con otros procesos en base a la clínica y lasdiferentes pruebas de imagen que suelen ser fundamentales y decisivas para el diagnóstico. La base del tratamiento es la liberación de la zona eliminando los elementos estructurales compresivos. (AU)

Popliteal artery entrapment syndrome is a rare nosological entity that affects not only the artery, but also the venous and nervouscomponent of the segments located at the level of the popliteal fossa. It is a pathology caused by the compression of these structuresby musculoskeletal elements located in this anatomical region that can cause more or less intense symptoms due to the injury of thestructures that are compressed. There are different anatomical forms which supports a morphological classification.It is necessary to carry out the differential diagnosis with other processes based on the clinic and the different imaging tests thatare usually fundamental and decisive for the diagnosis. The basis of the treatment is the liberation of the area, eliminating the compressive structural elements. (AU)

Digital-image analysis of the angiographic patterns of the popliteal artery in patients with aorto-iliac occlusive disease (Leriche syndrome).

Angiographic patterns of the popliteal artery are of great clinical relevance in vascular surgery below the knee. Using radiological, digital and statistical methods the variants and Luminal diameters of the popliteal artery branching in 46 men and 30 women with Lerich syndrome were studied. Statistical analysis did not reveal any gender or syntopic dimorphisms (P > or = 0.05). In subtype IA (87.5%) the anterior tibial artery and the short type of posterior tibioperoneal trunk were found. In subtype IB (2.63%) an arterial trifurcation was observed. In subtype IC (1.97%) the posterior tibial artery and the short type of anterior tibioperoneal trunk were seen. In two subtypes: IIA-1 (1.32%) and IIA-2 (0.66%) the anterior tibial artery and the long type of posterior tibioperoneal trunk were found. In subtype II B (5.92%) the long type of anterior tibioperoneal trunk and the posterior tibial artery were observed. The symmetry of the left and right poptiteal patterns was seen in two most frequent subtypes: I A (r1 = 0.80) and II B (r2 = 0.83). Either the anterior or posterior tibial artery had a smaller diameter than the coexisting tibioperoneal trunk (P<0.01). In a trifurcation the luminal diameters formed a decreasing sequence of the following arteries: anterior tibial, posterior tibial and peroneal. The angiometric analysis of luminal diameters showed the predominant vessel in each subtype: anterior tibioperoneal trunk (IC, IIB), posterior tibioperoneal trunk (IA, IIA-1, IIA-2) and anterior tibial artery (IB).
