Kissing Intravascular Balloon Lithoplasty and Endovascular Aortic Repair as a Treatment of Severe Distal Aorto-Iliac Occlusive Disease to Ensure a Safe Conduit to Facilitate Thoracic Endovascular Aort
Background: We describe a novel case of treating severe distal aorto-illiac occlusive disease and endovascular aortic repair with kissing endoluminal lithoplasty balloons. This ensured a safe conduit to facilitate thoracic endovascular aortic repair. Case Presentation: A patient with multiple comorbidities including coronary artery disease and peripheral artery disease (Rutherford 4 symptoms bilaterally) presented to the emergency room with chest pain and dyspnea on exertion. The patient was found to have a 3.5 cm descending thoracic aortic aneurysm, multiple penetrating aortic ulcers (PAU’s) within the descending thoracic aorta which was felt to be the cause of her chest pain along with heavily calcified occlusive aorto-iliac disease. The patient was deemed high surgical risk for open repair and the patient’s severe calcific distal aortic stenosis and bilateral severe ostial iliac stenosis was deemed a barrier for endovascular repair. Therefore, the patient was successfully treated with kissing balloon lithoplasty for lesion preparation of the heavy calcification and placement of an endovascular stent graft (EVAR) in the distal aorta, which ensured a safe conduit for thoracic endovascular aortic repair (TEVAR) procedure. Conclusion: As patients become more and more complex it is important to explore endovascular treatment options especially when surgical risk is high. Balloon lithoplasty and graft placement of calcified aorto-iliac bifurcation is a safe approach to develop a clear conduit for TEVAR.
