Innominate vein stenosis or thrombotic occlusion can occur in dialysis patients. Central vein stenosis is a common problem in patients on dialysis. Placement of a central vein catheter for dialysis access increases the risk of central vein stenosis. Central vein stenosis sometimes can jeopardize the arteriovenous fistula and arteriovenous graft in the ipsilateral extremity unless recognized early and treated. We describe three patients with left innominate vein stenosis who were known case of chronic kidney disease on haemodialysis and had a left brachio-cephalic fistula and presented with unilateral facial and upper limb oedema...

Although vessel perforation rarely occurs during percutaneous transluminal angioplasty of a central venous stenosis, it can be a rapidly fatal complication when accompanied by pericardial tamponade. The present case report details our experience with this dangerous complication. It also highlights the risk factors for and the pathogenesis of central venous stenosis, the clinical findings associated with inadvertent vessel perforation during an intervention, and anesthetic management strategies for pericardial tamponade resulting from vessel perforation...

Central venous stenosis (CVS) is encountered frequently among hemodialysis patients. Prior ipsilateral central venous catheterization and cardiac rhythm device insertions are common risk factors, but CVS can also occur in the absence of this history. Chronic CVS can cause thrombosis with partial or complete occlusion of the central vein at the site of stenosis. CVS is frequently asymptomatic and identified as an incidental finding during imaging studies. Symptomatic CVS presents most commonly as an upper- or lower-extremity edema ipsilateral to the CVS...

Subtotal parathyroidectomy may be indicated in patients with chronic renal failure and tertiary hyperparathyroidism, a population at increased risk for central venous stenosis (CVS) due to repeated vascular access. Here we report a case of complete upper airway obstruction precipitated by subtotal parathyroidectomy with ligation of anterior jugular vein collaterals in a patient with occult CVS. This case demonstrates a previously unreported risk of anterior neck surgery in patients with chronic renal failure...

PURPOSE: We present a case of external iliac vein patch venoplasty to accommodate rescue vascular access via a PTFE loop arterio-venous fistula Graft (AVG) for a patient with multiple central venous stenoses. METHODS: A 35 year old female with anti-glomerular basement membrane antibody disease required rescue vascular access for haemodialysis. Repeated occlusion and/or thrombosis of long term central venous access canulae, to facilitate dialysis, had caused stenosis of brachiocephalic veins; right external iliac vein and occlusion of the left common iliac vein...

Hemodialysis remains the most commonly used RRT option around the world. Technological advances, superior access to care, and better quality of care have led to overall improvement in survival of patients on long-term hemodialysis. Maintaining a functioning upper extremity vascular access for a prolonged duration continues to remain a challenge for dialysis providers. Frequently encountered difficulties in clinical practice include (1) a high incidence of central venous catheter-related central vein stenosis and (2) limited options for creating a functioning upper extremity permanent arteriovenous access...

End stapler is one of the indispensable devices for pulmonary resections. Various surgical staplers are now available and appropriate types are selected to dissect pulmonary parenchyma, vessel, or bronchus. In this study, we retrospectively reviewed the patients who received pulmonary wedge resections using newly released curved stapler (Endo GIA Radial Reload with Tri-Staple technology). Between April 2013 and October 2014, 10 lesions from the 9 patients were resected using the curved staplers. The reasons for the application of the staplers were pleuro-pulmonary adhesion in 3 lesions and centrally location in 7 lesions...

OBJECTIVE: The purpose of this study was to evaluate the correlation between the dilatation of the spinal epidural venous plexus (SEVP) and the amount of epidural fat (EF). METHODS: Between January 2007 and January 2012, 116 patients with prominent EF and 116 control subjects without prominent EF were included in this study. On the lumbar MR images, we graded the amount of EF and counted the number of vertebrae to determine the longitudinal extent of the EF. We evaluated and classified the dilatation of the SEVP and the degree of central canal stenosis...

BACKGROUND: Graft stenosis may be associated with future graft failure. The purpose of this investigation was to compare graft stenosis between radial artery (RA) grafts and saphenous vein grafts (SVGs) at least 5 years postoperatively using the multicenter Radial Artery Patency Study (RAPS) data. METHODS: Two hundred thirty-four patients underwent late invasive angiography after coronary artery bypass operations. The study population consists of 163 patients with thrombolysis in myocardial infarction (TIMI) 3 flow of both the RA graft and study SVGs...

Once hemodialysis patients have exhausted all option for a permanent vascular access in both upper extremities, they are often relegated at many dialysis centers to permanent catheter dependence with all its attendant complications, including infections, frequent dysfunction, and central vein stenosis. This commentary makes the case that thigh grafts are a far superior alternative to dialysis catheters in many of these patients. Technical graft failure may occur in some patients due to severe femoral artery calcification, but screening for calcification by ultrasound or computerized tomography can reduce the likelihood of a technical failure...

Central venous stenosis is a well-known complication in patients with vascular access for hemodialysis. We report two cases involving patients on hemodialysis with arteriovenous fistulas who developed reversible unilateral conductive hearing loss secondary to critical stenosis of central veins draining the arteriovenous dialysis access. A proposed mechanism for the patients' reversible unilateral hearing loss is pterygoid venous plexus congestion leading to decreased Eustachian tube patency. Endovascular therapy was conducted to treat the stenosis and the hearing loss of both patients was returned to near normal after successful central venous angioplasty...

Venous anomalies are diagnostic and therapeutic challenges. Subclavian or superior vena cava stenosis can be developed and venous return can be achieved via cardiac veins and coronary sinus in patients with central venous catheter for long-term hemodialysis. These types of abnormalities are not extremely rare especially in patients with a history of central venous catheter placement. Detection of these anomalies and subclavian vein stenosis before the surgical creation of hemodialysis fistulae or tunneled central venous catheter placement may prevent unnecessary interventions in those patients...

A persistent left superior vena cava (PLSVC) is a rare, under-recognized congenital anomaly. The PLSVC is incidentally discovered during central venous access procedures when access is obtained from the left internal jugular vein. The vast majority of PLSVCs drain into the right atrium; however, it is critical to recognize a PLSVC that drains into the left atrium as it can predispose to systemic dispersion of emboli through bypassing the lungs. Additionally, PLSVC catheterization has also been previously reported to be associated with cardiac dysrhythmias, venous stenosis, coronary sinus thrombosis, cardiac tamponade, and cardiac arrest...

There is a correlation between central venous cannulation and the development of central venous stenosis. Minor retrosternal vein lesions can be easily missed. Computerized tomographic (CT) venography is the diagnostic procedure of choice. The aim of this study was to examine the complications after catheter implantation in patients with prior permanent catheter placement and to evaluate present diagnostic procedures performed prior to choosing permanent access site in order to reduce possible complications after catheter placement...

BACKGROUND: Obstruction of the iliocaval venous outflow tract is a common cause of acute and chronic venous symptoms. Percutaneous stenting is now frequently performed to alleviate obstruction in the central venous system. However, currently used stents were primarily designed for biliary or arterial indications and may not be optimal for use in the venous system. This study evaluated the safety and performance of a novel venous stent (NVS) designed specifically for venous applications in an in vivo venous animal model...

Central vein stenosis is common because of the placement of venous access and cardiac intravascular devices and compromises vascular access for dialysis. Endovascular intervention with angioplasty and/or stent placement is the preferred approach, but the results are suboptimal and limited. Primary patency after angioplasty alone is poor, but secondary patency can be maintained with repeated angioplasty. Stent placement is recommended for quick recurrence or elastic recoil of stenosis. Primary patency of stents is also poor, though covered stents have recently shown better patency than bare metal stents...
