Abstract

Background: Coarctation of aorta is narrowing of proximal descending aorta. Interventional procedures such as balloon angioplasty & stent implantation has been progressively in use as alternatives for surgery in increasing number of children with diagnosis of coarctation of aorta. The aim of this study was to evaluate the use of endovascular stent in children with coarctation of aorta.

Methods: We evaluated effectiveness and safety of stenting in all patients younger than 18 years old with coarctation and re-coarctation of aorta which treated by stenting between years 2004-9 at rajaei - heart centre in Tehran, Iran.

Results: we studied 53 patients younger than 18 years old with a follow up of six months. Totally 54 stents were implanted. Mean (±SD) age of the patients was 11.6±4.2yrs. Seventeen cases (32%) were younger than 10 years old, and 36 cases (68%) were 10 years and older. Mean (±SD) weight was 39.24±18kg. 16 cases weighting less than 25kg. Peak systolic pressure gradient (SPG) decreased from 46.26±17.07 to 1.03±0.19mmHg after procedure (p<0.001). There was no significant difference (p<0.001) in the gradient before and after stenting in the patients with native coarctation (Vs re-coarctation cases), less than 25 kg and under 10 years old groups. Complications developed in 44% of cases while dominantly were minor except in two cases re-dilatation of stent was not needed during six month of follow-up of the patients.

Conclusions: Stenting of coarctation of aorta can decrease complications and can be used safely in children weighing bellow 25kg and in children below 10yrs old.

Abstract

Background: Carotid endarterectomy (CEA) is a standard method for patient with significant carotid stenosis but direct surgical repair via carotid endarterectomy may not be a good option in some patients because of the overall health status that may make the surgery too risky. Carotid angioplasty and stenting (CAS), is a relatively new procedure for the treatment of carotid artery disease in patients who may not be fit enough to undergo surgery. In this investigation, we determined short- and long-term outcomes of stent angioplasty in high-risk patients for whom the risk of perioperative morbidity and mortality is high.

Methods: We have followed 82 consecutive symptomatic patients with a ≥50% and asymptomatic patients with a ≥70%- 80% carotid stenosis within 15.9 months of angioplasty and stenting in Baqiyatallah and Jamaran hospitals from 2008-2010. All the patients were considered poor surgical candidates by experienced surgeons and anesthesiologists upon pre-surgical consultation.

Results: This descriptive cross-sectional study was performed on 28 women and 54 men with a mean age of 69.7±9.2 years. The procedure was technically successful in 79 (96.3%) cases. There were 6 (7.3%) deaths, 5 (6.1%) strokes, 4 (4.9%) MIs and 4 (4.9%) TIAs during the follow-up period.

Conclusion: The clinical results during the short available follow-up period suggested stent angioplasty to be useful, effective, reliable and safe in the treatment of significant cervical carotid stenosis in high-risk patients. Further analytical investigations with longer follow-up periods for predicting risk factors are recommended.

Abstract
Background: Congenital nasolacrimal duct obstruction (CNLDO) is one of the most prevalent orbital diseases in children and treatment of recalcitrant cases is always challenging. The purpose of this study is to identify the effectiveness of balloon dacryoplasty and stenting in persistent congenital nasolacrimal duct obstruction following previous intubation of nasolacrimal duct.
Methods: Our study was an interventional study from January 2015 to January 2018 on 16 lacrimal systems of 11 patients (5 males and 6 females) with congenital obstruction of the lacrimal duct (CNLDO) and a history of unsuccessful probing and stenting, in Farabi Hospital of Tehran (affiliated to Tehran University of Medical Sciences). Children who presented to our hospital and had previously been probed with or without intubation by another surgeon first underwent reprobing and re-intubation with a Crawford tube. Endoscopy of the nasolacrimal system was performed in suspected cases of false stent passage or in the presence of a history indicating nasal pathology. Crawford's Monoka tube was removed after two months. Balloon dacryoplasty with intubation was performed as the third surgery in cases who did not respond to probing and stenting after 3-6 months. The success after six months was evaluated using fluorescein dye disappearance test (FDDT) and also the resolution of the patients' symptoms.

Results: The age of the patients was 67±35.01 months (range: 26-121). The site of the canalicular stenosis in our patients was in the common canaliculi or within 2-3 mm from it. After 6 months, surgery was successfully performed in 13 lacrimal systems (81.25%). One patient with congenital lacrimal duct obstruction and Down syndrome and two other patients did not respond to balloon dacryoplasty and stenting and subsequently underwent dacryocystorhinostomy (DCR).
Conclusion: Balloon dacryoplasty combined with Monocrawford intubation is an effective surgical procedure that should be considered in cases of congenital nasolacrimal duct obstruction who have not responded to the probing and stenting of the lacrimal system.
