CPT® Code 37619

The procedure described by CPT® Code 37619 involves the ligation of the inferior vena cava (IVC), which is a critical intervention aimed at preventing pulmonary embolism. This condition can arise when deep vein thromboses, or blood clots, migrate from the pelvis or lower extremities to the lungs, posing significant health risks. The ligation procedure is performed using an extravascular technique, which means that the ligation is done outside the vessel itself. Before the ligation, a cavogram is conducted to assess the vascular anatomy and to ensure that there are no existing thrombi within the IVC that could complicate the procedure. The surgical approach requires an incision in the abdomen to access the IVC, which is then carefully exposed and dissected from the surrounding tissues. The procedure involves either partially or completely interrupting blood flow through the IVC, followed by the placement of a suture ligature around the vessel. Additionally, the wall of the IVC may be plicated, a technique that creates folds around the vessel to narrow its lumen, further aiding in the prevention of blood clot migration. Finally, the abdominal incision is closed in layers to promote proper healing.
