Abstract: Pulmonary sequestration is a pulmonary malformation in which a portion of nonfunctioning bronchopulmonary tissue is separated from the rest of the lung parenchyma. We report the case of a 48-year-old woman with history of chronic pneumonia, studied with computed tomography and in whom we obtained three dimensional evaluation of the pathological structures.

Abstract: Patients with combined valvular-aortic disease undergo surgical reconstruction of the aortic root with a valved composite graft. Two of the techniques used to replace the aortic valve and ascending aorta are Bentall and Cabrol procedures. Cabrol surgical procedure uses a Dacron tube that enables coronary artery revascularization. Graft limb occlusion may however occur. Digital subtraction angiography, magnetic resonance angiography and multidetector computed tomography angiography are useful imaging methods for the evaluation of surgical-related complications. We report the case of a patient treated by the Cabrol technique, who was studied with contrast-enhanced multidetector computed tomography angiography to evaluate long-term post-surgical complications and coronary vessels patency.
