Revascularization of the Superficialized Brachial Artery

The superficialized brachial artery (SBA) is an important alternative vascular access for hemodialysis patients when autogenous vein fistula creation is not feasible. However, repeated puncture of the SBA can lead to severe complications such as aneurysm formation, pseudoaneurysm, and infection. This study aimed to review surgical strategies for revascularization and infection control in SBA aneurysms.

We retrospectively analyzed 8 cases of SBA aneurysms treated at our institution between November 2020 and June 2025. Patient demographics, comorbidities, surgical procedures, and outcomes were evaluated based on medical records and follow-up data.

Patients ranged in age from 43 to 81 years and had been on dialysis for an average of 19 years. Six aneurysms were ruptured, and 5 were associated with infection. Brachial artery bypass was the most common procedure, performed in 6 patients using autologous veins or prosthetic grafts. One patient underwent fistula closure with a bovine pericardial patch, and another received direct arterial anastomosis. In infected cases, autologous vein bypass or aneurysm resection with direct anastomosis was performed after thorough debridement. All patients maintained adequate dialysis access postoperatively.

Revascularization of the SBA using autologous vein bypass is effective for managing aneurysms, especially in infected cases. Careful infection control and individualized surgical planning are essential for maintaining safe dialysis access and preserving limb function.
