We reported a 21-year-old patient with strict descending aorta coarctation and small post-ductal patent ductus arteriosus, complicated with abortion and hypertension. The patient was successfully treated by endovascular stent-graft with a single cardiac catheterization. Endovascular stent-graft is an easy, safe, and reliable intervention for the treatment of strict descending aorta coarctation and small post-ductal patent ductus arteriosus.

Coarctation of the thoracic aorta is a common congenital heart disease (approximately 6-8%) and it is associated with other congenital cardiac defects, particularly bicuspid aortic valve, mitral valve abnormality, and ventricular septal defect . Rarely coarctation of the thoracic aorta may occur in combination with patent ductus arteriosus (PDA) -.
Endovascular stenting is rapidly becoming preferred intervention for the thoracic aorta disease, such as coarctation, aneurysm, and dissection. A recent study was shown that, primer angioplasty or stenting and surgical repair have similar efficacy for the treatment of aortic coarctation . Combination of aortic coarctation and PDA can be treated with therapeutic catheterization and several types of devices -.
Herein, we reported a case with descending aortic coarctation and PDA combination, which is successfully treated by using endovascular stent-graft on a single angiographic catheterization.
A 21-year-old white Turkish woman referred to our department for the investigation of new onset hypertension developed one week after a miscarriage. Past medical history was insignificant except for miscarriage and there was no history of hypertension before and during pregnancy period. Physical examination revealed weak femoral pulses and brachiofemoral delay. Right and left arm, and leg blood pressures were 190/110 mmHg, 140/90 mmHg, and 80/50 mmHg, respectively. A grade 3/6 systolic murmur was heard over the precordial and interscapular areas.
After the procedure, patient was monitored for 48 hours for possible complications and blood pressure control. Blood pressure was returned to normal limits as were the discrepancy between arm and legs. No anti-hypertensive medication was needed after the procedure and the patient was discharged with 300 mg acetyl salicylate. The patient was followed for eight months without any problem and on her last visit repeat catheterization showed no gradient across the grafted segment or evidence of PDA.
Coarctation of the thoracic aorta is a common congenital heart defect, and consists of the localized shelf in the posteriolateral aortic wall opposite to the ductus arteriosus . Complex coarctation is defined as coarctation in the presence of other important intracardiac abnormalities (e.g., ventricular septal defect, mitral stenosis and bicuspid aorta with stenosis). Simple coarctation refers to coarctation in the absence of such lesions and most common form detected de novo in adults . Complex coarctation and combination with patent ductus arteriosus was uncommon in adults and presented only in case reports [3, 4, 7]. Significant coarctation requires a gradient greater than 20 mmHg across the coarctation segment of angiography with or without hypertension. Our patient had a complex coarctation with post-ductal PDA and had a peak gradient of 102 mmHg. Unless treated coarctation has a poor prognosis and most patients die from stroke, coronary artery disease or sudden death by the fourth decade .
Aorta coarctation is an unusual cause of hypertension in pregnancy however 58% of patients with significant coarctation develop hypertension during pregnancy . Distally decreased blood pressure due to aortic stenosis causes placental hypoperfusion, therefore recurrent abortion is not uncommon in this population [10, 11].
A recent study suggested that primary angioplasty or stenting and surgical repair has similar efficacy in treating patients with native aorta coarctation . One approach is closure of PDA with coils or amplatzer duct occluder and correction of coarctation by balloon dilatation or stenting either simultaneously or sequentially [4, 13]. This technique can be used in pediatric population however in adults' serious complications like aneurysm, dissection, hematoma, and rupture of aorta may ensue .
More recently, percutaneous intraluminal stent-graft placement by transluminal catheter technique was introduced as an alternative intervention in two independent case reports [3, 5]. The aim of procedure is to close entry site of PDA. Both cases were successfully treated without any complication. In these reports, both PDAs were pre-ductal, one was being moderate the other one was large sized. Our case had a small-sized, post-ductal PDA and complete occlusion was achieved after percutaneous intraluminal stent-graft without any complication.
Transluminal endovascular stent-graft placement is an effective, easy to perform method for the treatment of aortic coarctation combined with post-ductal PDA even for adult patients. This technique has advantages of being far less invasive than surgery and reduced exposure time to fluoroscopy, therefore we believe that it would be widely preferred technique in the future for the correction of such anomalies.
Written informed consent was obtained from the patient for publication of this case report and accompanying images. A copy of the written consent is available for review by the Editor-in-Chief of this journal.
