CPT® Code 34490

Thrombectomy is a surgical procedure aimed at removing a thrombus, or blood clot, from a blood vessel. In the context of CPT® Code 34490, this procedure specifically targets the axillary and subclavian veins, which are major veins located in the upper body. The procedure can be performed either directly or with the assistance of a catheter, and it involves making an incision in the arm to access the affected vein. The presence of a thrombus often occurs in areas where the vein may be narrowed or stenotic, leading to potential complications such as impaired blood flow. During the thrombectomy, the surgeon makes an incision to expose the vein, allowing for direct access to the thrombus. Vessel loops are strategically placed both above and below the thrombus to control blood flow during the procedure. The thrombus can then be removed through direct exposure, or alternatively, a catheter may be used to facilitate remote removal. This involves inserting a balloon catheter beyond the clot, inflating it, and then withdrawing it to capture and remove the thrombus. After the thrombus is removed, a venography may be performed to confirm that the vein is clear and patent, ensuring that no residual clot remains. It is important to note that CPT® Code 34490 is specifically used when the thrombus is removed via an arm incision, distinguishing it from other codes that may apply to different approaches or locations of thrombus removal.
