A systematic review of standardized methods for assessment of endograft sealing on computed tomography angiography post-endovascular aortic repair, and its influence on endograft-associated complications.

A systematic review of standardized methods for assessment of endograft sealing on computed tomography angiography post-endovascular aortic repair, and its influence on endograft-associated complications. Expert Rev Med Devices. 2019 Jul 13;: Authors: Schuurmann RCL, de Rooy PM, Bastos Gonçalves F, Vos CG, de Vries JPM Abstract Introduction: Although there is much attention for proper sizing of pre-operative anatomy before (thoracic) endovascular aneurysm repair ([T]EVAR), standardized assessment of endograft position and apposition at post-operative imaging is seldom addressed in the international guidelines. The highly detailed three-dimensional computed tomography angiography (CTA) volumes contain valuable information about the apposition of the endograft with the arterial wall and the position of the device relative to anatomical landmarks in the proximal and distal landing zones, which is currently hardly used. With proper assessment on CTA of the endograft after EVAR, the risk for future endograft-related complications may be determined, allowing patient-tailored, risk-stratified surveillance. Areas covered: This systematic review identified three standardized methods for assessing apposition or position of the endograft in the proximal or distal landing zone on CTA after (T)EVAR. Quantification of apposition and position, validation of measurement precision, and association with endograft-related complications were extracted....
