Aortic Morphology Following Endovascular Repair of Acute and Chronic Type B Aortic Dissection: Implications for Management

Life table plotting cumulative survival (%) against time (months), in patients having undergone endovascular repair for acute (AAD) or chronic aortic dissection (CAD). The numbers of patients at risk at each time point are given in tabular form. The cumulative survival for patients with CAD is significantly worse that for patients with AAD (P=0.015, Kaplan Meyer).

Life table plotting cumulative false lumen thrombosis rate at the mid point of the endovascular stent (%) (a) and below the level of the endograft (b) against time (months), in patients undergoing endovascular repair for acute (AAD) or chronic aortic dissection (CAD). The numbers of patients at risk at each time point are given in tabular form.

Bar graph plotting mean short axis diameter of the thoracic aorta, false lumen and true lumen at the level of the endograft (a) and below the level of the endograft (b) against time (months after procedure; Pre-diameter before endovascular repair, Post-immediately after repair). Values given are median with interquartile range and range. The separate graphs represent values for acute aortic dissection (AAD) and chronic aortic dissection (CAD). The numbers at each time point are equivalent to Fig. 2.

Graph illustrating the percentage of patients having undergone endovascular repair of an acute aortic dissection (a) and chronic aortic dissection (b) that demonstrated enlargement, reduction or stasis in the maximum short axis diameter of the descending thoracic or abdominal aorta at varying time intervals after treatment. Enlargement and reduction were defined by a change of more than 5mm from the pre-treatment CT. Numbers of patients in each category are given.
