Catheter thrombosis

Owain Thomas, Hampus Rein, Karin Strandberg, Ulf Schött
BACKGROUND: The risk of spinal haematoma in patients receiving epidural catheters is estimated using routine coagulation tests, but guidelines are inconsistent in their recommendations on what to do when results indicate slight hypocoagulation. Postoperative patients are prone to thrombosis, and thromboelastometry has previously shown hypercoagulation in this setting. We aimed to better understand perioperative haemostasis by comparing results from routine and advanced tests, hypothesizing that patients undergoing major upper gastrointestinal surgery would be deficient in vitamin K-dependent coagulation factors because of malnutrition, or hypocoagulative because of accumulation of low molecular weight heparin (LMWH)...

Blood-contacting devices, such as intravascular catheters, suffer from challenges related to thrombus formation and infection. Nitric oxide (NO) is an endogenous antiplatelet and antimicrobial agent. Exogenous release of NO from various polymer matrices has been shown to reduce thrombosis and infection of/on implantable medical devices. However, the clinical applications of such materials have been hindered due to factors such as NO donor leaching and thermal instability. In this study, a novel approach is demonstrated in which one lumen of commercial dual lumen catheters is dedicated to the NO release chemistry, allowing the other lumen to be available for clinical vascular access...

PURPOSE: To describe all post-insertion complications involving most used intravascular access, and to determine whether the use of a new-generation transparent dressing (3M™ IV Advanced) might reduce their number and impact on ICU patient outcomes. METHODS: Patients older than 18, with an expected length of stay ≥48 h and requiring at least one central venous catheter (CVC), arterial catheter (AC), haemodialysis catheter (HDC), pulmonary arterial catheters (PAC) or peripheral venous catheter (PVC) were randomized into two groups: a new-generation transparent dressing, or the hospital's classical transparent dressing, and were followed daily for any infectious and non-infectious complications...

Venous thromboembolism (VTE) is the second leading cause of death in patients with cancer. These patients are at an increased risk of developing VTE and are more likely to have a recurrence of VTE and bleeding while taking anticoagulants. Management of VTE in patients with cancer is a major therapeutic challenge and remains suboptimal worldwide. In 2013, the International Initiative on Thrombosis and Cancer (ITAC-CME), established to reduce the global burden of VTE in patients with cancer, published international guidelines for the treatment and prophylaxis of VTE and central venous catheter-associated thrombosis...

Injuries to blood vessels near the heart can quickly become life-threatening and include arterial injuries during central venous puncture, which can lead to hemorrhagic shock. We report 6 patients in whom injury to the subclavian artery and vein led to life-threatening complications. Central venous catheters are associated with a multitude of risks, such as venous thrombosis, air embolism, systemic or local infections, paresthesia, hemothorax, pneumothorax, and cervical hematoma, which are not always immediately discernible...

BACKGROUND: Breast reconstruction with microvascular free tissue transfer has become a widely used method. Despite a high rate of success, a compromised flap necessitating re-exploration can occur. Here, we introduce direct thrombectomy as a flap salvage technique, and compared the results with conventional thrombectomy. METHODS: A total of 488 patients who underwent breast reconstruction using a free transverse rectus abdominis myocutaneous flap between March 2009 and February 2014 were retrospectively analyzed...

OBJECTIVE: We evaluated the incidence of percutaneous superior vena cava catheter-related thrombosis and identified risk factors for developing the condition in patients undergoing cardiovascular surgery with cardiopulmonary bypass. METHODS: A total of 121 patients were evaluated. A percutaneous superior vena cava catheter was inserted into the right internal jugular vein during cardiovascular surgery with cardiopulmonary bypass. The right internal jugular vein was evaluated using ultrasonography, including cross-sectional area and velocity just before insertion of the percutaneous superior vena cava catheter (preoperative) and 24 hours and 48 hours after its insertion...

Poly(l-lactide) (PLLA) is the structural material of the first clinically approved bioresorbable vascular scaffold (BVS), a promising alternative to permanent metal stents for treatment of coronary heart disease. BVSs are transient implants that support the occluded artery for 6 mo and are completely resorbed in 2 y. Clinical trials of BVSs report restoration of arterial vasomotion and elimination of serious complications such as late stent thrombosis. It is remarkable that a scaffold made from PLLA, known as a brittle polymer, does not fracture when crimped onto a balloon catheter or during deployment in the artery...

BACKGROUND: Central venous access devices (CVADs) play an important role in the management of pediatric oncology patients; unfortunately, they are also associated with potentially serious complication rates. We hypothesized that, despite the significantly different disease courses typical of acute lymphoblastic leukemia and acute myelogenous leukemia, there would be identifiable risk factors for premature CVAD removal. METHODS: We retrospectively studied clinical characteristics and procedure records for all patients admitted with a leukemia diagnosis at our institution from May 2009 to July 2014...

Deep venous thrombosis (DVT) is a common disorder with a significant mortality rate. Successful endovascular treatment of acute DVT is most likely to be achieved in patients with recently formed thrombus, (<10-14 days) with acute iliofemoral DVT. Endovascular treatment options include: Catheter-directed thrombolysis (CDT), pharmacomechanical catheter-directed thrombolysis (PCDT), percutaneous aspiration thrombectomy (PAT), vena cava filter protection, venous balloon dilatation and venous stent implantation...

Children with malignancy require venous access that is reliable, safe and compliant on a long-term basis. There is little data available on utilization of totally implantable venous access devices (TIVAD) for long term chemotherapy in children in an Indian setting [1]. We report our long-term follow-up results of utilization of totally implantable venous access devices for long-term chemotherapy in children. This was a retrospective analysis of 122 children requiring long-term chemotherapy done between January 2008 and December 2013...

The obstruction of blood flow through the superior vena cava (SVC) into the right atrium may present as a severe clinical syndrome. One of the benign causes of SVC obstruction is the long-term use of indwelling catheters and wires, increasing the chances of SVC thrombosis. The treatment of the benign SVC syndrome is focused on achieving long-term durability and patency of the superior venocaval system and normal life expectancy. We report the successful surgical management of a patient with severe symptomatic SVC syndrome and emphasize technical details that might be of value in treating this challenging pathologic condition...

Venous thoracic outlet syndrome (VTOS) is uncommon but most frequently occurs in young, active, healthy patients. This condition typically presents as subclavian vein (SCV) effort thrombosis, also known as Paget-Schroetter syndrome. The pathophysiology underlying VTOS is chronic repetitive compression injury of the SCV in the costoclavicular space, resulting in progressive venous scarring, focal stenosis, and eventual thrombosis. Clinical evaluation includes a history and physical examination followed by catheter-based venography, for definitive confirmation of the diagnosis and initial treatment with pharmacomechanical thrombolysis...

BACKGROUND: Inferior vena cava (IVC) thrombosis may occur in patients with iliofemoral deep venous thrombosis (DVT), and its impact on thrombolysis outcomes is poorly defined. This study compared outcomes of patients undergoing thrombolysis for acute iliofemoral DVT with and without IVC involvement. METHODS: Patients who underwent thrombolysis for iliofemoral DVT between May 2007 and March 2014 were identified from a prospectively maintained database and divided into two groups: those with IVC involvement and those without...
