Persistência da veia ciática

Abstract: CONTEXTO: Durante um período da vida embrionária, a veia ciática é a principal coletora do membro inferior. Na embriogênese vascular, há diferenciação dos angioblastos em um plexo vascular primitivo, com posterior remodelagem e expansão. Consequentemente, durante esse processo, podem ocorrer anomalias. Quando ocorre persistência da veia ciática, esta pode se comunicar com a veia safena parva ou com a veia poplítea durante seu percurso, anastomosando-se com a veia perfurante superior e com a veia circunflexa me… Show more

“…Persistent sciatic vein is considered a rare congenital anomaly [4]. As observed by us, the 5% frequency of this anomaly corresponds with recent results of 6.25% obtained during analysis of lower limbs from 16 cadavers [3].…”

“…PSV can be present unilaterally [5,[13][14][15] or bilaterally, [5,7,11,12] and can occur as a single large vein [4,12] or a network of veins. [4,5] It can also present concurrently with a persistent sciatic artery.…”

“…[2,5,6] When present, the PSV can assume any of the three forms as described by Cherry et al [5] as; complete type (arises from the popliteal vein or its tributaries, ascends along the sciatic nerve, and terminates in the internal iliac vein), upper type (arises from the muscular veins of the upper thigh, runs along the sciatic nerve and terminates in the internal iliac vein) or the lower type (limited to the distal thigh, arises from the popliteal fossa, and terminates in the deep femoral vein). [5,7,8] We present here a case of a unilateral large complete PSV and discuss the epidemiology, anatomy, diagnosis and management of PSV.…”
