Pseudoaneurisma humeral secundario a punción arterial inadvertida / Brachial artery pseudoaneurysm secondary to inadvertent arterial puncture

RESUMEN Los pseudoaneurismas de la arteria humeral son infrecuentes, pero pueden asociarse a complicaciones de alta morbilidad como la isquemia de miembro superior. Comunicamos un caso de pseudoaneurisma humeral en el pliegue del codo, que se presentó como tumor pulsátil con leve disminución de la temperatura y parestesias en la mano homolateral de un año de evolución, debido a una punción arterial inadvertida durante la venopunción para extracción de sangre. Se trató con éxito mediante resección quirúrgica más reconstrucción vascular con bypass húmero-cubital y bypass húmero-radial ambos con vena safena. Se discuten las diversas opciones terapéuticas disponibles para los pseudoaneurismas humerales considerando las características anatómicas y la sintomatología del paciente.

ABSTRACT Brachial artery pseudoaneurysms are rare but can be associated with severe complications as ischemia of the upper extremity. We report a case of a brachial artery pseudoaneurysm in the crease of the elbow presenting as a pulsating mass with progressive growth over the past year. The ipsilateral hand was sightly cold and presented paresthesia. The lesion was due to inadvertent arterial puncture during venipuncture. The pseudoaneurysm was successfully treated with surgical resection and vascular reconstruction with a brachial to ulnar artery bypass and brachial to radial artery bypass with saphenous vein graft. The different therapeutic options available for brachial artery pseudoaneurysms are discussed, considering the anatomic characteristics and patients' symptoms.

Intrauterine upper limb thrombosis: an unusual presentation

Intrauterine thrombosis with extremity ischemia presenting at birth in a newborn is a rare event. A 29 year old mother, 2nd gravida with one first trimester spontaneous abortion delivered a 33week gestation male preterm baby. On Examination, the entire left upper limb was ischemic and edematous with an absent flow on Doppler USG. Low molecular weight heparin (LMWH) was started after which gradually the limb turned pink with good volume pulsations. Thrombophilia mutation studies revealed the heterozygous state for the MTHFR (C677T) mutation only in the mother. Prompt diagnosis and early treatment has a favourable outcome in cases of intra-uterine thrombo-embolism.
