Abstract:
A 65-year-old man with no-option chronic limb-threatening ischemia underwent percutaneous deep venous arterialization (pDVA). An arteriovenous fistula (AVF) was created using a modified venous arterialization simplified technique. During the balloon dilation of the AVF site, the venous puncture site was accidentally also dilated, resulting in massive bleeding. The angiographic bleeding was controlled by stent graft deployment, and the final angiography revealed good DVA flow. Two weeks post-pDVA, the patient developed right shin pain. Suspecting a subcutaneous hematoma and infection, extensive debridement was performed. The patient's wounds completely healed approximately 7 months after the pDVA.
Learning Objective:
Modified venous arterialization simplified technique (m-VAST) is a feasible technique for percutaneous deep venous arterialization; however, it may lead to unexpected complications. When performing m-VAST, the possibility of puncture site complications should be carefully considered.
