INTRODUCTION: Currently, venography is the standard diagnostic method to examine veins before implementing access, which is invasive in nature. Computerized tomography venography (CTV) can simultaneously indicate deep and superficial venous systems in the upper extremity and their relation to the surrounding anatomical structures; however, its diagnostic value in the detection of central venous disease has yet to be defined. The aim of this study was to determine the diagnostic value of CT venography compared to venography in the diagnosis of stenosis and the occlusion of subclavian veins and the superior vena in renal failure patients...

Maintenance of central venous access in patients with chronic medical conditions such as short bowel syndrome demands forethought and ingenuity. We describe an innovative technique for re-utilizing central venous access sites in patients who have chronic central venous access needs. Records of patients undergoing this technique were reviewed between August 2012 and December 2015. The technique involves "cutting-down" to the sterile fibrous tunnel that naturally forms around tunneled catheters. The fibrous sheath is then isolated and controlled much as would be done for a venous "cut-down...

INTRODUCTION: One of the frequent complications suffered by patients with chronic renal failure is the lack of vascular access due to venous thrombosis. This means that the transplant surgeon must have a detailed knowledge of the intra-abdominal venous system, and other alternative surgeries, at the time of performing the renal graft implant, in order to ensure a good venous drainage. PRESENTATION OF THE CASE: This article provides a case report regarding a patient with no vascular access and with surgical difficulties at the time of the kidney transplant, in whom a renal-portal venous drainage was performed with very good outcome...

BACKGROUND: Totally implantable venous access ports (TIVAPs) are used for prolonged central venous access, allowing the infusion of chemotherapy and other fluids and improving the quality of life of children with cancer. TIVAPs were developed to reduce the infection rates associated with central venous catheters; however, infectious events remain common and have not been fully investigated in pediatric oncology patients. PROCEDURE: A retrospective cohort was formed to investigate risk factors for central line-associated bloodstream infection (CLABSI) in pediatric cancer patients...

BACKGROUND: Intradialytic hypotension (IDH) has a dramatic impact on the main outcomes of dialysis patients. Early warning of hemodynamic worsening during dialysis would enable preventive measures to be taken. Blood oxygen saturation (SO2) is used for hemodynamic monitoring in the critical care setting and may provide useful information about IDH onset. AIM: To evaluate whether short- and medium-term variations in the SO2 signal (ST-SO2var, MT-SO2var,) during dialysis are a predictor of IDH...

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...

BACKGROUND: Hemodialysis as an efficient therapy for advanced CKD is the most used treatment modality all over the world. Even though primary AVF is widely accepted as a best permanent vascular access in hemodialysis patients, up to 60% of all fistulas fail to mature. The pathogenesis of early fistula failure is not very well understood. Many general and local factors are involved: patient's age, sex, primary renal disease, small vessel's diameter, presence of accessory veins, prior venipunctures, surgical skill, genetics, etc...

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...

INTRODUCTION: Chronic venous disease (CVD) of the lower limbs is a common problem. It is more prevalent in women than in men and has a significant impact on patients' quality of life (QoL) and on the healthcare system. The aim of this study was to evaluate the efficacy of sulodexide in adult patients with CVD of the lower limbs and its effect on patients' QoL. METHODS: Patients with CVD were treated with sulodexide [250 LSU (lipasemic units) twice daily] for 3 months in a setting of real-life clinical practice...

PURPOSE: Dialysis settings have generally improved over the last decades, but the vascular access setting did not see significant advances and experienced a progressive worsening in epidemiology and clinical features. The aim of the study was to describe and compare evolution of vascular access in Italy over time. METHODS: A national survey implemented in Italy last year is presented and compared to a previous survey performed in 1998. Present survey collected data from almost 50% of centers involved in vascular access...

Native arterio-venous fistulae (AVF) are vascular access of first choice for chronic hemodialysis. However, AVF are also associated with many adverse events like: primary or secondary failure, infection, lymphedema, stenosis, thrombosis, and ischemia of distal extremities. The most common ischemia related complications of AVF are: ischemic neuropathy and steal syndrome with its consequences like pain and peripheral necrosis. Ischemic muscle contracture is a rare complication of AVF. Herein, we are reporting a case of Volkmann's ischemic contracture developing after creation of brachiocephalic AVF...

OBJECTIVE: There is an increasing number of procedures that traditionally were performed in the inpatient setting that are now becoming office-based procedures. These include peripheral endovascular procedures such as angiograms, angioplasties, dialysis access interventions, and treatment for venous insufficiency. We chose to evaluate the feasibility, safety of inferior vena cava (IVC) filter placement in the office-based setting. METHODS: All procedures were performed using local anesthesia, and ultrasound guidance for puncture...

When peritoneal dialysis is inapplicable, chronic hemodialysis (HD) becomes the only available treatment option in small children. Due to small patient size, central venous catheters (CVC) are mainly used for vascular access. Over the past 4 years, four children weighing less than 15 kg received chronic HD in our unit. A total of 848 dialysis sessions were performed. Altogether, 21 catheters were inserted. In all but one occasion, uncuffed catheters were used. Catheter revision was performed 15 times during the study period, either due to infection or catheter malfunction...

INTRODUCTION: Peripherally inserted central catheters (PICCs) are a popular alternative to central venous lines. PICCs can provide reliable long-term access for intravenous fluids, antibiotics and total parenteral nutrition. Multiple factors can contribute to difficult PICC removal including adherent fibrin and thrombus formation around the catheter. We discuss a novel endovascular retrieval technique to remove tightly adherent PICCs. CASE PRESENTATION: A 42-year-old male with history of chronic pancreatitis requiring intravenous pain medications, presented with right upper extremity single lumen PICC that could not be removed by standard techniques...

BACKGROUND: Hypothetically, psychotic disorders could be caused or conditioned by immunological mechanisms. If so, one might expect there to be peripheral immune system phenotypes that are measurable in blood cells as biomarkers of psychotic states. METHODS: We used multi-parameter flow cytometry of venous blood to quantify and determine the activation state of 73 immune cell subsets for 18 patients with chronic schizophrenia (17 treated with clozapine), and 18 healthy volunteers matched for age, sex, BMI and smoking...

BACKGROUND: For patients with end-stage renal disease who are not candidates for fistula, dialysis access grafts are the best option for chronic haemodialysis. However, polytetrafluoroethylene arteriovenous grafts are prone to thrombosis, infection, and intimal hyperplasia at the venous anastomosis. We developed and tested a bioengineered human acellular vessel as a potential solution to these limitations in dialysis access. METHODS: We did two single-arm phase 2 trials at six centres in the USA and Poland...

Access to the circulation is an "Achilles' heel" of chronic hemodialysis. According to the current guidelines, autologous arteriovenous fistula is the best choice available. However, the impossibility of immediate use and the high rate of non-matured fistulas place fistula far from an ideal hemodialysis vascular access. The first attempt at constructing an angioaccess should result in functional access as much as possible. After failed attempts, patients and nephrologists lose their patience and confidence, which results in high percentage of central venous catheter use...

Chronic venous insufficiency is a prevalent disease that frequently leads to development of venous leg ulcers. While a number of evidence-based clinical practice guidelines have been developed that provide guidance for clinicians when caring for patients with chronic venous insufficiency, they lack adequate detail concerning selection and application of compression for prevention and management of venous leg ulcers. In order to address this need, the WOCN Society appointed a task force to develop an algorithm for compression for primary prevention, treatment, and prevention of recurrent venous leg ulcers in persons with chronic venous insufficiency...
