CPT® Code 75957

Endovascular repair of descending thoracic aorta (eg, aneurysm, pseudoaneurysm, dissection, penetrating ulcer, intramural hematoma, or traumatic disruption); not involving coverage of left subclavian artery origin, initial endoprosthesis plus descending thoracic aortic extension(s), if required, to level of celiac artery origin, radiological supervision and interpretation

The CPT® Code 75957 refers to the endovascular repair of the descending thoracic aorta, which is a critical procedure performed to address various vascular conditions. This procedure is indicated for patients suffering from conditions such as aneurysms, pseudoaneurysms, dissections, penetrating ulcers, intramural hematomas, or traumatic disruptions of the aorta. The endovascular approach allows for a minimally invasive repair, which is advantageous compared to traditional open surgical methods. The procedure involves the placement of an initial endoprosthesis, which is a type of stent graft, and may include additional descending thoracic aortic extensions if necessary, extending to the level of the celiac artery origin. During the procedure, radiological supervision and interpretation are essential components, ensuring that the placement of the endoprosthesis is accurate and effective. This includes performing angiography of the aorta and its branches prior to the deployment of the endovascular prosthesis, as well as fluoroscopic guidance throughout the procedure. The use of imaging techniques allows for real-time visualization of the aortic anatomy, facilitating the precise placement of guidewires, catheters, and the endovascular prosthesis itself. Additionally, intraprocedural angiography is conducted to confirm the correct positioning of the prosthesis, detect any potential endoleaks, and evaluate blood flow. The comprehensive nature of this procedure underscores its importance in managing complex aortic conditions while minimizing patient recovery time and associated risks.
