Abstract
Coarctation of the aorta (CoA) is the most frequent congenital anomaly of the thoracic aorta, consisting of a narrowing usually located in the proximal descending aorta just distal to the left subclavian artery. Isolated coarctation can remain clinically silent until adolescence or adulthood, presenting as primary hypertension with symptoms like headache, leg fatigue and leg cramps. In CoA echocardiography is most useful in infants and children. In adults suprasternal notch view is most helpful; color Doppler can be used to localize the site of turbulence. Continuous wave Doppler can assess the pressure gradient. Multislice computed tomography (MSCT) angiography has recently been introduced as a noninvasive method in the detection and quantification of coarctation. The aim of the work to evaluate the role of multidetector computed tomography (MDCT) angiography in assessment of coarctation of the aorta. The study included 40 patients with suspected or confirmed aortic coarctation by echocardiography and clinical picture; they underwent MSCT angiography in the period from March 2017 and March 2018. The suitable patients were subjected to thorough history taking and clinical examination, echocardiography and MDCT angiography. Data were collected and analyzed after all 40 patients underwent echocardiography, multi-slice CT and surgical repair . The degree of stenosis was considered significant in 24 cases. All coarctations were diagnosed correctly by axial, multiplanar and three dimensional images with 100% sensitivity. Echocardiography missed the diagnosis of coarctation of aorta in 5 cases which was confirmed after these patients underwent surgical repair. In conclusion: MDCT angiography is the method of choice in preoperative morphologic assessment of coarctation of the aorta in pediatric and adult patients.
