Current status of thoracic aortic endograft repair

摘要: The optimal approach for the surgical repair of diseases thoracic aorta poses a challenging problem vascular and cardiothoracic surgeons. Thoracic aortic aneurysms (TAAs), Stanford type B dissections, penetrating ulcers, traumatic tears can all present in acute or chronic setting. majority these pathologies excluding trauma occur more commonly elderly medically debilitated. Frequent conditions patients with dissections include hypertension, coronary artery disease, obstructive pulmonary congestive heart failure. These comorbidities significantly worsen outcomes even preclude conventional open repair. Because often prohibitive operative risks involved thoracotomy advent endoluminal technology, endografting has emerged over last decade as viable alternative. Due to aging population most countries world increasing prevalence age, physicians will encounter higher frequency. incidence TAAs is estimated be high 10 cases per 100,000 people year, dissection affecting 9000 year United States alone [1–4]. Penetrating ulcers are much rare clinical entity, may develop into aneurysm at risk rupture if left untreated [5,6]. Traumatic tears, disease typically younger patients, encountered up 18% motor vehicle accidents, mortality rates 90% field, 40% 70% those who survive transport center [7,8]. For each
