    Clinical & Coding Specifications

    Clinical Context

    A 58-year-old male with a history of central venous catheter placement presents with acute swelling and pain of the right upper extremity and neck. Duplex ultrasound demonstrates an occlusive thrombus of the right subclavian vein with impaired venous outflow and progressive arm edema despite systemic anticoagulation. The vascular surgery team schedules an open thrombectomy via a neck incision to access the subclavian vein, remove the clot, and restore flow; a Fogarty catheter may be used intraoperatively for extraction. Typical workflow: preoperative evaluation and imaging (ultrasound, venography), informed consent, general anesthesia, transverse or oblique neck incision, exposure of the subclavian vein, thrombectomy with or without catheter-directed techniques, intraoperative hemostasis and possible venoplasty, wound closure, postoperative monitoring for bleeding, anticoagulation management, and follow-up venous duplex to confirm patency.
