Mdct Assessment of Major Aorto-Pulmonarycollaterals
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 1
Abstract
Objective: To describe the importance of performing MDCT(Multidetector-row computed tomography) in the management of patients with pulmonary atresia-ventricular septal defect(PA-VSD) and to assess the variations in pulmonary arterial circulation, assessment of major aorto-pulmonary collaterals and other associated anomalies of the cardiovascular system. Methodology: MDCT with intravenous contrast was performed in three adult patients, two of them presented with cyanotic spells and one patient presented with dyspnoea. Various image reformatting techniques including maximum intensity projection (MIP) and curved multi-planar reconstruction(MPR) and volume-rendering technique (VRT) were used. Results: In these three patients, the main pulmonary arteries were congenitally absent, and the blood supply to pulmonary circulation was totally carried out by major aorto-pulmonary collateral arteries (MAPCAs). MDCT provided detailed road map for evaluation of MAPCAs, estimation of the number and site of origin, their diameters, courses, and the lobes of the lungs supplied by them. MDCT could provide an efficient road map to guide safe selective catheterization and could be a substitute for conventional angiography. Conclusion: The management plan of this particular congenital cardiac malformation is mainly determined by the morphology of main pulmonary arteries and the presence of extra-cardiac sources of pulmonary blood supply and the vasculature of the lung parenchyma is well assessed with MDCT which is the non-invasive imaging technique of choice in the detailed evaluation of this condition.
