[Treatment Strategy for Aortic Arch Aneurysms to Minimize the Complications:Which should be Chosen, Endovascular Treatment or Open Repair?].

The technologies of endovascular treatment for aortic pathologies have progressed rapidly, and endovascular treatment for thoracic pathologies has gained widespread acceptance, and there has been a significant increase in the number of thoracic pathologies treated by thoracic endovascular aortic repair (TEVAR) over the last decade. The initial results of TEVAR such as operative mortality and morbidities have been good and acceptable. Therefore, indication of TEVAR has expanded along with the improvement of techniques and devices. However, as its mid-term and long-term results became available, complications including stroke, endoleaks and consequent aneurysm rupture have become apparent. Open repair is still the important treatment option because its results are acceptable and durable. This article provides an treatment strategy of aortic arch aneurysms to minimize the complications.
