OBJECTIVES: Surgery for vascular anomalies can occasionally fail to relieve symptoms, especially when severe tracheobronchial malacia persists. We studied outcomes in children who underwent airway stenting for severe post-surgical airway malacia and tested known clinical and surgical prognostic factors. METHODS: Among 257 children evaluated for tracheobronchial vascular compression, we reviewed the clinical charts for the 59 patients (23%) who underwent surgery...

BACKGROUND: Transcatheter techniques are emerging for left atrial (LA) decompression under venoarterial extracorporeal membrane oxygenation (VA-ECMO). We aimed to assess whether balloon atrioseptostomy (BAS) is a safe and efficient strategy. METHODS: All patients who underwent percutaneous static BAS under VA-ECMO at four tertiary institutions were retrospectively reviewed. RESULTS: From 2000 to 2014, BAS was performed in 64 patients (32 adults and 32 children)...

We have repaired a unilateral absent pulmonary artery(UAPA) using a prosthetic graft with a ring. Case 1 was a 1-month old girl. The right pulmonary artery(RPA) was anti-anatomically reconstructed with a 4 mm ePTFE graft. In postoperative year 1, however, the graft became stenosed due to compression by the ascending aorta. We reversed the stenosis with a 6 mm stent by percutaneous transluminal angioplasty. Case 2 was 6-year old boy. His RPA was anatomically reconstructed with a ringed 5 mm ePTFE graft when he was 5-months old...

Management of pulmonary atresia with ventricular septal defect (PA-VSD) in the neonatal period presents numerous challenges. Endovascular stenting of the ductus arteriosus or of a collateral vessel in ductal-dependent pulmonary circulation as an alternative to the Blalock-Taussig (BT) shunt has become increasingly popular in the last decades. The utilization of the reverse Szabo (anchor-wire) technique for single collateral vessel stenting in a case of PA-VSD is described.

Hybrid stage I palliation combines cardiothoracic surgery and interventional transcatheter procedures for treatment of hypoplastic left heart syndrome. The approach is an alternative to the Norwood procedure, the traditional first stage of surgical palliation. Hybrid stage I palliation involves placing bilateral branch pulmonary artery bands and a patent ductus arteriosus stent through a median sternotomy, performed without cardiopulmonary bypass. The purpose of the bands is to control blood flow to the lungs and protect the pulmonary bed while the stent sustains systemic cardiac output...

BACKGROUND: Options for cardiac valve replacement in children are limited to fixed-diameter prostheses that do not accommodate for somatic growth. An externally stented bovine jugular vein graft has been modified for surgical valve replacement in pediatric patients, with the intention of subsequent valve expansion in the catheterization laboratory as the child grows. METHODS: Pediatric patients at a single institution who underwent surgical implantation of an expandable bovine jugular vein valve between 2010 and 2014 were reviewed retrospectively...

Managing a patient scheduled for bronchoesophageal fistula repair is challenging for the anesthetist. If appropriate ventilation strategy is not employed, serious complications such as hypoxemia, gastric distension, and pulmonary aspiration can occur. We present the case of a 62-year-old man with a bronchoesophageal fistula in the left main stem bronchus requiring the insertion of a Y-shaped tracheobronchial stent through a rigid bronchoscope, under general anesthesia. We successfully managed this intervention and herein report this case to demonstrate the effectiveness of underwater seal gastrostomy tube drainage used in conjunction with high-frequency jet ventilation during bronchoesophageal fistula stenting...

BACKGROUND: Congenital anomalies of the coronary arteries(CAs) are rare and are often diagnosed incidentally during a conventional coronaryangiography. Recently, the incidence of these congenital defects is on the rise particularly after the introduction of the electrocardiography (ECG) gated coronary computed tomographic angiography (CCTA). This innovative radiological screening modality has led to the most precise mapping of the course of the CAs on Computed Tomographic Scan. The aim of the study is to determine the prevalence and describe theCAscongenital anomalies and their variations in Kuwaiti population at a single institution experience...

Congenitally corrected transposition of the great arteries is a rare abnormality accounting for approximately 1% of clinically apparent congenital heart disease. Age at time of diagnosis and survival rate vary and depend on associated anomalies, including pulmonary stenosis, ventricular septal defect, atrial septal defect, atrioventricular block, and atrioventricular valve regurgitation. Reported cases of corrected transposition of the great arteries with single coronary ostium anomaly and atrial septal defect are very rare...

UNLABELLED: Atherosclerotic renal artery stenosis is an increasingly recognized medical problem especially in elderly patients. It commonly occurs with systemic manifestations including hypertension (HTN), chronic kidney disease (CKD) or atherosclerotic diseases including coronary or peripheral artery disease. Significant renal artery stenosis may result in HTN, ischemic nephropathy, however it is still in debate about the benefit of revascularization. Although several randomized controlled trials including Angioplasty and Stenting for Renal Artery Lesions (ASTRAL) and Cardiovascular Outcomes in Renal Atherosclerotic Lesions (CORAL) study has failed to reveal a significant benefit of angioplasty, angioplasty with medical therapy is increasingly accepted in some patients with certain clinical conditions...

OBJECTIVE: Carotid interventions are important in helping to reduce the risk of stroke for patients with high-grade carotid artery stenosis; however, subclinical cerebral microemboli can occur during these procedures. Associations have been found between the incidence of microemboli and postoperative decline in memory. We therefore sought to determine whether this decline persisted long-term and to assess changes in other cognitive domains. METHODS: Patients were prospectively recruited under an Institutional Review Board-approved protocol at a single academic center...

The present study was aimed at assessing initial results of hybrid operations in obstructive lesions of the iliac-femoral veins in patients with post-thrombotic disease (PTD). Hybrid operations [open endovenectomy from the common femoral vein (CFV) with creation of an arteriovenous fistula + stenting of iliac veins] were performed carried out in a total of eleven patients with PTD. Of these, there were 7 men and 4 women aged from 34 to 52 years (mean age - 42.8±7 years). All patients had severe-degree chronic venous insufficiency (CVI)...

Failing Fontan physiology in univentricular hearts manifest with protein-losing enteropathy, plastic bronchitis, low cardiac output, and recurrent effusions. Transcatheter creation of fenestration in a failing Fontan may be useful in alleviating the symptoms by improving the cardiac output. It is traditionally achieved by puncturing through the conduit from femoral or jugular venous access. In the absence of good venous path, transhepatic access provides a direct route for needle puncture of the conduit. If marked intimal ingrowth into the conduit results in increasing rigidity and makes the conduit nonyielding, alternative approaches may be needed...

Double-J (DJ) stents are the main tools used in urological practice for prevention and treatment of obstruction. Stenting is also mandatory after complicated ureteroscopy or TUL (Transureteral Lithotripsy). Known complications are upper migration of DJ stents into the kidney and lower migration to the bladder. In a man with an impacted right lower ureteral stone, a DJ stent was placed because the ureteroscope was not passed from an intramural ureter. We reported a very rare complication of DJ ureteral stent placement with intravascular migration to the pulmonary arteries, which was removed percutaneously through the right femoral vein under fluoroscopic guidance...

A 94-year old female presented with sharp right flank pain. Imaging demonstrated herniation of the right renal pelvis and proximal ureter into a large diaphragmatic hernia. She underwent ureteral stent placement with resolution of her symptoms. Congenital diaphragmatic hernias can cause a variety of pulmonary, cardiac, and gastrointestinal symptoms. This is one of only three cases in the literature of unilateral kidney obstruction due to herniation of the renal pelvis and proximal ureter into a Bochdalek-type diaphragmatic hernia...
