OBJECTIVES: This study sought to obtain in vivo data on a new stent and delivery system specifically designed for implantation in infants with the ability to be enlarged to adult dimensions. BACKGROUND: There are no endovascular stents designed for or approved for use in infants, nor is there a stent capable of being implanted at infant vessel diameters and achieving adult size while maintaining structural integrity. The Minima stent was designed to address these needs...

Krzysztof Nowak, Mariusz Kusztal
Cardiovascular implantable electronic devices (CIEDs) are a standard therapy utilized for different cardiac conditions. They are implanted in a growing number of patients, including those with chronic kidney disease (CKD) and end-stage kidney disease (ESKD). Cardiovascular diseases, including heart failure and malignant arrhythmia, remain the leading cause of mortality among CKD patients, especially in ESKD. CIED implantation procedures are considered minor surgery, typically with transvenous leads inserted via upper central veins, followed by an impulse generator introduced subcutaneously...

BACKGROUND: Bypass surgery using a large saphenous vein graft, or another autologous venous graft, is a well-recognised treatment option for managing peripheral arterial disease of the lower limb, including chronic limb-threatening ischaemia (CLTI) and intermittent claudication, peripheral limb aneurysms, and major limb arterial trauma. Bypass surgery has good results in terms of limb preservation rates and long-term graft patency but is limited by the possibility of vein graft failure due to stenoses of the graft...

PURPOSE: Central venous stenosis (CVS) is usually a late-diagnosed clinical entity that is common in hemodialysis patients. It causes various problems ranging from hemodialysis difficulty to loss of the arterio-venous (A-V) fistula. In the present study, we aimed to determine the effect of drug eluting balloon while excluding the influence of other variable factors by evaluating the same individuals with plain and paclitaxel-eluting balloons. METHODS: This research was a prospective study of 18 symptomatic hemodialysis patients (age 50...

OBJECTIVE: Despite the widespread use of conventional percutaneous transluminal angioplasty (PTA), recurrence of cephalic arch stenosis (CAS), and low patency rate after PTA remain challenging problem. We aimed to identify the clinical predictors of recurrence of CAS and evaluate the effect of the access flow reduction on the fistula patency rate in patients with recurrent CAS. METHODS: In 1118 angiographies of 220 patients with CAS, access circuit patency rates after PTA and potential clinical predictors of recurrence of CAS were assessed...

Lower right internal jugular vein (RIJ) stenosis has been reported as a common cause of RIJ catheterization failure. However, the risk factors for lower RIJ stenosis in patients undergoing cardiac surgery is unclear. We reviewed the electronic medical records of all adult patients who had undergone cardiac operations in a single tertiary university hospital from January 2014 to January 2016. Patients were excluded if they were lack of preoperative contrast-enhanced chest computed tomography (CT) studies. Lower RIJ stenosis was defined as a ratio of cross-sectional area at the smallest level to cross-sectional area at the largest level less than 25%...

Central venous stenosis in hemodialysis patients rarely causes venous hypertension and intracranial hemorrhage. A 54 year-old male with right arm arteriovenous fistula was transferred to our institution in a comatose state following right parietal venous infarction. Fistulography showed right brachiocephalic vein (BCV) occlusion with reflux into the right transverse sinus and obstruction of left internal jugular vein outflow due to the styloid process. Balloon venoplasty of the right BCV occlusion failed to improve the patient's status because of the delayed diagnosis...

Central venous stenosis (CVS) refers to a significant stenosis of a large intrathoracic vein, such as the subclavian, brachiocephalic, or the superior vena cava (hemodialysis, HD). Percutaneous transluminal angioplasty (PTA) with or without stent placement has been the recommended as the preferred approach to CVS. A total of 10 consecutive HD patients with documented CVS over a 2-year time period from April 2017-April 2019 underwent percutaneous angioplasty and stent insertions under sedation. The procedure was performed by the interventional cardiologist in the institute...

OBJECTIVE: Central venous stenosis (CVS) is one of the most challenging complications in hemodialysis patients. Venous thoracic outlet syndrome (vTOS) is an underappreciated cause of CVS in a dialysis patient which may result in failed percutaneous intervention and loss of a functioning dialysis access. Limited data exist about the safety and outcome of first rib resection in HD patients, and results have been confounded by variable surgical approaches. The purpose of this study was to evaluate the safety, operative outcomes, and patency of the existing dialysis access after trans-axillary thoracic outlet decompression...

Here we describe the use of a VBX balloon expandable stent-graft (WL Gore, Flagstaff, AZ, USA) to treat a right brachiocephalic vein stenosis in a haemodialysis patient prior to ipsilateral upper limb arterio-venous (AV) fistula formation. Balloon expandable stent-grafts are unsuitable for treating peripheral fistula stenoses due to their susceptibility of being crushed. The right brachiocephalic vein is both relatively short in comparison to the left and is less susceptible to extrinsic compression and the use of such a device to treat stenosis here allows for very accurate placement and restoration of luminal diameter...

OBJECTIVE: This review examines the evidence regarding treatment of central vein obstruction (CVO) in the setting of ipsilateral haemodialysis access. The aim is to identify whether long-term venous patency following central vein stenting is superior compared to balloon venoplasty. To date, there are no evidence-based guidelines to direct management of CVO in the setting of ipsilateral haemodialysis access. METHODS: An extensive systematic database search was performed using Medline, Embase and Cochrane Databases to identify all articles published since January 2000 to November 2019 comparing the management of CVO with venoplasty and/or stenting in the setting of ipsilateral haemodialysis access fistulae/grafts...

Central vein stenosis and thrombosis are frequent in patients on haemodialysis for end-stage renal disease. Its management includes anticoagulation, systemic or catheter-directed thrombolysis, mechanical thrombectomy and percutaneous transluminal angioplasty (PTA). Use of mechanical thrombectomy in central vein thrombosis has been scarcely reported. We hereby report a case of right brachiocephalic vein thrombosis with underlying stenosis, which was successfully treated by mechanical thrombectomy followed by PTA and stenting...

BACKGROUND: Extracranial carotid artery stenosis is the major cause of stroke, which can lead to disability and mortality. Carotid endarterectomy (CEA) with carotid patch angioplasty is the most popular technique for reducing the risk of stroke. Patch material may be made from an autologous vein, bovine pericardium, or synthetic material including polytetrafluoroethylene (PTFE), Dacron, polyurethane, and polyester. This is an update of a review that was first published in 1996 and was last updated in 2010...

BACKGROUND: Portal hypertension commonly accompanies advanced liver disease and often gives rise to life-threatening complications, including bleeding (haemorrhage) from oesophageal and gastrointestinal varices. Variceal bleeding commonly occurs in children and adolescents with chronic liver disease or portal vein thrombosis. Prevention is, therefore, important. Randomised clinical trials have shown that non-selective beta-blockers and endoscopic variceal band ligation decrease the incidence of variceal bleeding in adults...

INTRODUCTION: Tunneled cuffed catheters (TCC) are generally used as a temporary means to provide hemodialysis (HD) until permanent arteriovenous access is established. However, certain complications are associated with use of TCCs such as infections, catheter malfunction/malposition or venous stenosis. Limited data is available on outcomes and long term complications associated with TCCs in our country. The aim of this study was to study the outcomes of TCCs and associated long term complications during the course of its usage...
