A left brachiocephalic fistula failure associated with an anomalous drainage of the cephalic and its rescue. A case report. Rev. mex. angiol. [online]. 2023, vol.51, n.4, pp.134-138.  Epub 16-Abr-2024. ISSN 2696-130X.  https://doi.org/10.24875/rma.23000009.

Anatomical variants are relatively common findings, and venous stenosis could cause complications in vascular access for hemodialysis. The objective was to determine if endovascular treatment is possible to solve complications of vascular access with abnormal drainage in the cephalic arch. A 59-year-old woman referred to her hemodialysis center for evaluation of her failing left brachiocephalic arteriovenous fistula, which had been used without complications for 4 years. In the last month, she has presented signs of recirculation and elevated venous pressure. Dilation of the left cephalic vein and arterial pulses present were observed. Pulsatile left brachiocephalic fistula, without a thrill. A diagnostic phlebography was performed in which AVF patency was observed with an abnormal outlet in the external jugular vein, with signs of stenosis. The lesion was crossed, and simple angioplasty was performed. Venography demonstrated almost complete resolution of the stenosis. Five months after, the patient was on dialysis. We concluded that endovascular treatment is a valid option for the treatment of venous stenosis in anatomical variants.
