Staged endovascular treatment for complicated type B aortic dissection

Abstract

BACKGROUND: A 40-year-old man presented with acute chest and back pain, hypertension and anuria. Two years previously he had been diagnosed with acute uncomplicated type B aortic dissection. Following conservative management, with aggressive antihypertensive therapy and analgesia, he was monitored with 6-monthly surveillance CT scans. These demonstrated a complicated type B dissection with renal and iliac malperfusion. INVESTIGATIONS: Multislice CT, transthoracic and transesophageal echocardiography, digital subtraction aortography. DIAGNOSIS: Acute-on-chronic type B aortic dissection, complicated by aneurysmal dilatation of the thoracic aorta and visceral malperfusion. MANAGEMENT: Antihyper..
