CPT® Code 34502

The procedure described by CPT® Code 34502 refers to the reconstruction of the vena cava, which is a major vein responsible for returning deoxygenated blood to the heart. This procedure is typically indicated in cases of malignant invasion, where cancerous growths compromise the integrity of the vena cava, necessitating resection and subsequent reconstruction. Other reasons for performing this procedure include the presence of saccular aneurysms, congenital malformations, or traumatic injuries that affect the vena cava. The specific approach to reconstruction is determined by whether the superior or inferior vena cava is involved and the precise location of the lesion, defect, malformation, or injury. During the reconstruction process, various techniques may be employed depending on the extent of the damage. For minimal defects, direct suture repair may be sufficient. In cases where a longitudinal resection is required, an interposition graft may be utilized to bridge the gap. If a segment of the vessel is excised, a tubular graft may be necessary to restore continuity. The surgical procedure involves careful exposure of the vena cava, and if the resection is due to malignant invasion, the surgeon will excise the lesion along with a margin of healthy tissue to ensure complete removal of cancerous cells. In instances of aneurysms, malformations, or traumatic injuries, the affected segment of the vena cava is removed, and the reconstruction is performed using techniques such as running sutures, vascular staplers, or grafts made from synthetic materials, bovine pericardium, or the patient's own pericardium. This comprehensive approach aims to restore the function of the vena cava while minimizing complications and ensuring patient safety.
