BACKGROUND AND OBJECTIVES: Central vein stenosis is considered to be common in patients on hemodialysis but its exact prevalence is not known. In this study, we report the prevalence of central vein stenosis in patients with CKD referred for vein mapping. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: We conducted a retrospective study of adult patients who had bilateral upper extremity venographic vein mapping from September 1, 2011 to December 31, 2015. Patients with and without stenosis were compared for differences in clinical or demographic characteristics...

Objective: To report the results of angioplasty with paclitaxel-coated balloons for the treatment of early restenosis of central veins in hemodialysis patients. Materials and Methods: Sixteen patients (9 men and 7 women; mean age 65.8 ± 14.4 years; range, 40-82 years) with 16 episodes of early restenoses of central veins within 3 months (median patency duration 2.5 months) were enrolled from January 2014 to June 2015. Ten native central veins and 6 intra-stent central veins were treated with double paclitaxel-coated balloons (diameter 6-7 mm) plus a high pressure balloon (diameter 12-14 mm)...

Cardiac rhythm disorder is frequently encountered in hemodialysis patients and is often treated with a cardiovascular implantable electronic device (CIED). The conventional CIED requires placement of transvenous leads resulting in subclinical central venous stenosis, which can adversely affect the successful creation of a permanent dialysis vascular access. The technological advancement of a leadless pacemaker provides an opportunity to implement a strategy to preserve central veins in patients with chronic kidney disease...

The right internal jugular vein (IJV) is an important access site for hemodialysis catheterization. Venous cannulation failure is usually caused by central venous stenosis and is rarely related to vessel malformation. We herein present a case of failure to place a tunneled hemodialysis catheter into the right IJV. The patient had an arteriovenous fistula in the right arm with inadequate flow and a history of multiple central venous catheterizations. The guidewire was repeatedly misplaced into the right subclavian vein (SV) regardless of the technique used...

Symptomatic obstruction related to malignant involvement of large veins may occur in central veins both in the thoracic and pelvic regions, and in the abdominal region of the body. Both cases represent a therapeutic challenge, and endovascular revascularization, consisting of angioplasty and stent placement, is safe and effective. Superior vena cava stenting has become widespread in the management of occlusive venous disease. The percutaneous placement of large expandable metal stents allows rapid restoration of normal blood flow in the majority of patients, thus improving symptoms...

INTRODUCTION: Recurrent central venous restenosis is problematic in patients with ipsilateral arteriovenous fistula. We report our experience using a drug-eluting stent for the treatment of recurrent central vein restenosis. CASE REPORT: A 60-year-old man consulted our hospital because of recurrent swelling of his left upper limb with radial-cephalic arteriovenous fistula that originated in the distal forearm. More than 3 years prior, two bare-metal stents were placed for the obstructed lesions in the left subclavian and brachiocephalic venous lesions, and repeated balloon angioplasty for recurrent in-stent stenosis was performed approximately every 3 months...

INTRODUCTION: Venous access is essential in patients with haemophilia for administration of factor concentrates. Peripheral venipuncture may be challenging, particularly in young children or during immune tolerance induction (ITI). Central venous access devices (CVADs) carry a significant risk for complications. An alternative for venous access is peripheral arteriovenous shunts (AVSs), but there is sparse documentation in the literature. The aim of this study was to document our experience with AVS over 12 years in 27 boys with severe haemophilia...

For arrhythmia treatment or sudden cardiac death prevention in hemodialysis patients, there is a frequent need for placement of a cardiac implantable electronic device (pacemaker, implantable cardioverter defibrillator, or cardiac resynchronization device). Leads from a cardiac implantable electronic device can cause central vein stenosis and carry the risk of tricuspid regurgitation or contribute to infective endocarditis. In patients with end-stage kidney disease requiring vascular access and cardiac implantable electronic device, the best strategy is to create an arteriovenous fistula on the contralateral upper limb for a cardiac implantable electronic device and avoidance of central vein catheter...

The objectives of central venous percutaneous transluminal angioplasty are to dilate the venous lesion and to extend the life of arteriovenous fistula for hemodialysis. It is reasonable to perform percutaneous transluminal angioplasty for central venous lesions if this interventional therapy is required to maintain stable dialysis therapy. However, the presence of large fresh thrombus at central venous lesion site represents a contraindication to percutaneous transluminal angioplasty unless the thrombus can first be removed by thrombectomy...

BACKGROUND: Significant stenoses in arteriovenous fistulae (AVFs) or arteriovenous grafts (AVGs) with limitation of flow and dialysis inadequacy should prompt consideration for fistuloplasty. We sought to identify fistulae, lesions, and patient-specific variables, which predict for outcomes after fistuloplasty. METHODS: Data were extracted retrospectively from a renal access database from 2011 to 2016 of patients undergoing fistuloplasty. Demographics, comorbidities, outcomes of intervention, and flow rates documented on preintervention and postintervention duplex were collected...

BACKGROUND: Construction of radiocephalic arteriovenous fistula (RC-AVF) results in successful hemodialysis (HD) in approximately 40% of end-stage renal disease patients. We investigated whether RC-AVF flow measured by ultrasound 30 days postoperative predicted successful HD. METHODS: In this prospective study, color Doppler ultrasound was used to measure cephalic vein outflow volume at 3 forearm sites at 1 and 3 months postoperatively. RESULTS: Of 45 consecutive patients screened for feasibility of RC-AVF by physical examination and US arterial and vein mapping, 41 were considered suitable for construction of RC-AVF...

BACKGROUND: Femoro-popliteal bypass is implemented to save limbs that might otherwise require amputation, in patients with ischaemic rest pain or tissue loss; and to improve walking distance in patients with severe life-limiting claudication. Contemporary practice involves grafts using autologous vein, polytetrafluoroethylene (PTFE) or Dacron as a bypass conduit. This is the second update of a Cochrane review first published in 1999 and last updated in 2010. OBJECTIVES: To assess the effects of bypass graft type in the treatment of stenosis or occlusion of the femoro-popliteal arterial segment, for above- and below-knee femoro-popliteal bypass grafts...

Superior vena cava (SVC) stenosis or thrombosis is a well-known complication of central venous catheterization for endocavitary treatments, hemodialysis, or chemotherapy. In cancer patients, these SVC lesions are often symptomatic due to intimal damage and chemotherapy toxicity. We report our experience with six patients treated between 2007 and 2012 via an endovascular approach (n=5) or a direct surgical approach (n=1). All patients had SVC syndrome with facial edema, headache and upper limb edema. In three cases, the catheter was in place when the clinical symptoms occurred...

Cardiac tamponade caused by perforation of the cardiac wall is a rare complication related to central venous catheter (CVC) placement. A 71-year-old female with a previous history of moderate aortic stenosis and kidney transplantation was admitted to hospital due to global heart failure and worsening of allograft function. Intensified hemodialysis was commenced through a CVC placed in the right subclavian vein. Chest radiography revealed catheter tip in the right atrium and no signs of pneumothorax. Thorough diagnostics outruled immediate life-threatening conditions, such as myocardial infarction and pulmonary embolism...

Peripherally inserted central catheter (PICC) migration into azygos vein (AV) is a rare complication. It is recognised only when catheter malfunction occurs or when patients develop associated complications. PICC migration into AV has been reported to be associated with various complications such as catheter malfunction, perforation, haemorrhage, thrombosis, infection and stenosis of AV. Pleural effusion and trachea-azygos fistulas have also been reported. We present a patient with recurrent migration of PICC into AV after an initial corrective repositioning during the same hospital stay...

BACKGROUND: Intimal hyperplasia has been historically associated with improper venous remodeling and stenosis after creation of an arteriovenous fistula. Recently, however, we showed that intimal hyperplasia by itself does not explain the failure of maturation of 2-stage arteriovenous fistulas. We seek to evaluate whether intimal hyperplasia plays a role in the development of focal stenosis of an arteriovenous fistula. METHODS: This study compares intimal hyperplasia lesions in stenotic and nearby nonstenotic segments collected from the same arteriovenous fistula...

Central vein stenosis/occlusion is a common well-described sequel to the placement of hemodialysis catheters in the central venous system. The precise mechanisms by which central vein stenosis occurs are not well known. Current concepts in central vein stenosis pathophysiology focus on the response to vessel injury model, emphasizing the process of trauma. A case of left brachiocephalic vein stenosis due to the insertion and function of a temporary right subclavian hemodialysis catheter is presented. The purpose of the manuscript is to emphasize that, with the introduction of a temporary subclavian hemodialysis catheter via the right subclavian vein apart from causing concurrent stenosis/infarction of the right subclavian and right brachiocephalic vein, it is also possible to cause stenosis of the left brachiocephalic vein (close to its contribution to the superior vena cava) although the catheter tip is placed in the correct anatomical position in the superior vena cava...

INTRODUCTION: Arteriovenous fistulae (AVF)-associated reactive angioendotheliomatosis (RAE) is a very rare entity (three previously reported cases in the literature) that can manifest as extremity wounds. RAE's etiopathology is unknown. CASE DESCRIPTION: We report a case of severe limb-threatening upper extremity wound with pathology-proven RAE. This lesion was previously refractory to standard wound care. There was no evidence of limb ischemia or steal syndrome, previously deemed to be the underlying cause of AVF-associated RAE in other reports...

Hemoptysis may occur in patients with pulmonary venous obstruction and prominent decompressing vessels in the airways adjacent to the affected pulmonary veins. The options for treatment of hemoptysis are limited, particularly when efforts to alleviate pulmonary venous obstruction have failed. Here we describe a patient with hemoptysis associated with stenosis of the central left upper pulmonary vein and occlusion of the central left lower pulmonary vein. The left upper pulmonary vein was dilated with balloon catheters and a vascular plug was placed in the left lower pulmonary artery...

BACKGROUND: Peripheral venous hypertension and microvascular injury have merged as central features of chronic venous disease. Peripheral venous pressure in the lower limb is controlled by central and peripheral mechanisms. In the current manuscript, we examine the role of peripheral factors, particularly conduit capacitance compliance, focal stenosis, and arterial inflow into the calf. METHODS: An experimental venous model using Penrose tubing as a venous analogue was used where the aforementioned parameters could be manipulated...
