Description
Summary:The persistent sciatic artery is an uncommon disease, considered an axial congenital vascular malformation due to the lack of involution of the sciatic artery during embryonic development. It may be associated with abnormalities in the development of the iliac, common femoral and superficial femoral arteries. Patients may be asymptomatic, or they could present chronic pain, such as sciatic neuralgia, caused by nerve damage, since it is close to the abnormal persistent vessel, or due to ischemic pain, as a result of a thrombosis or embolism of an aneurysm, which could compromise the viability of the limb. La arteria ciática persistente es una entidad poco frecuente, considerada como una malformación vascular congénita de tipo axial por falta de involución de la arteria ciática durante el desarrollo embrionario. Puede, o no, asociarse con alteraciones en el desarrollo de las arterias iliaca, femoral común y/o femoral superficial. Clínicamente los pacientes pueden ser asintomáticos, o pueden manifestar un dolor crónico tipo neuralgia ciática, por irritación nerviosa, al estar contigüidad con el vaso anómalamente persistente, o por dolor isquémico, al sufrir trombosis de un aneurisma que con relativa frecuencia suele desarrollarse en este vaso anómalamente persistente, o por embolia arterial distal, pudiendo llegar a comprometer la viabilidad de la extremidad.
