RESUMO
BACKGROUND: Inadvertent placement of a port-a-catheter in an artery during central venous cannulation is rare and can result in devastating complications. Although traditional closure devices have been employed as prompt and adequate treatment, more innovative devices such as collagen plugs are being studied for their efficacy. CASE: We report a case involving a 63-year-old woman who was treated with chemotherapy for recurrent metastatic uterine leiomyosarcoma. During port-a-catheter placement, puncture of the subclavian artery occurred. Vascular surgery and interventional radiology consultation was obtained, wherein an Angio-Seal device was used to seal the exit from the subclavian artery. Angio-Seal placement was successful and the patient has since become clinically stable and was then discharged. CONCLUSION: Subclavian artery puncture is rare but can occur due to the close proximity between the subclavian artery and vein. Prompt vascular surgery and radiology consultation is necessary. Although traditional manual compression and closure devices have been effective at restoring hemostasis, collagen seals or plugs may be more viable to treat this precarious situation.
