title: Complication of hybrid treatment in type B aortic dissection diagnosed by echocardiography.
abstract: This case illustrates an unusual and fatal complication after endovascular treatment of type B aortic dissection and highlights the role of echocardiography in the early diagnosis of complications. In this case, a patient with previous diagnosis of chronic type B aortic dissection and moderate aortic regurgitation underwent endovascular repair of the proximal descending aorta and conservative surgical correction of the aortic valve. On early postoperative, a transesophageal echocardiogram and aortic angiotomography demonstrated proximal endoleak by contrast extravasation around the proximal graft attachment site, causing compression of the stent in its middle portion, resulting in narrowing with reduced cross-sectional area.
