coarctation of aorta a congenital heart defect consisting of localized deformity of the tunica media of the aorta, causing narrowing (usually severe) of the lumen of the vessel
 Coarctation of the aorta. Flow patterns are normal but are diminished distal to the coarctation. Blood pressure is increased in vessels leaving the aorta proximal to the coarctation. From Betz et al., 1994.

We chose endovascular stenting technique to dilate the juxtaductal CoA of thoracic aorta, avoiding the relatively long time of cross-clamping at thoracic aorta, which is essential for the traditional surgical technique to treat the coarctation. To our knowledge, this is the first case featuring primary TEVAR to the CoA immediately followed by surgical decompression of spinal epidural hemorrhage in the emergent setting.
Pre and post coarctation aortic pressures were recorded.
[6] Foetal mortality rate also increases and can reach upto 20% as uterine perfusion decreases distal to coarctation end.
Pulmonary outflow tract obstruction and aortic coarctation occur in about 5 % cases.
Transcatheter stent implantation, preferably covered stent, is shown to be safe and efficient in treatment of this disease and was used successfully even in near-atretic coarctation cases.
When a coarctation is proximal to the left subclavian artery, systolic blood pressure is higher in the right arm than in the left arm [3].
All patients underwent aortic arch (AA) reconstruction via median sternotomy with coarctation resection and aortoplasty with autologous pulmonary
A diagnosis of severe post ductal coarctation of aorta was made and Balloon aortoplasty was planned for the patient.

Of the 131 collateral findings, 15 in 15 patients (prevalence: 2%) were classified as significant and deserving further diagnostic work-up: mediastinal lymphadenopathy/mass (6/15), lung nodule/mass (3/15), aortic coarctation (2/15), breast nodule (1/15), complex renal cyst (1/15), hepatic mass (1/15), and solid renal mass (1/15).
