OBJECTIVE The evaluation of the venous neurovasculature, especially the dural venous sinuses, is most often performed using MR or CT venography. For further assessment, diagnostic cerebral angiography may be performed. Three-dimensional rotational angiography (3D-RA) can be applied to the venous system, producing 3D rotational venography (3D-RV) and cross-sectional reconstructions, which function as an adjunct to traditional 2D digital subtraction angiography. METHODS After querying the database of Baylor St...

Percutaneous Central Venous Catheter (CVC) insertion using internal jugular and Subclavian veins routes is common procedure for all intensive care admitted patients and some patients in the ward as demand arises in central and referral hospitals of Botswana. This is a case report of a patient on whom a third attempt of re-inserting a CVC for fluid and total parenteral nutrition (TPN) was made. X-ray showed that left Subclavian inserted catheter was mis-directed to internal jugular vein of the same side creating discomfort to the patient...

Central venous oxygen saturation (ScvO2) in the superior vena cava is predominantly determined by cardiac output, arterial oxygen content, and oxygen consumption by the upper body. While abnormal ScvO2 levels are associated with morbidity and mortality in non-uremic populations, ScvO2 has received little attention in hemodialysis patients. From 1/2012 to 8/2015, 232 chronic hemodialysis patients with central venous catheters as vascular access had their ScvO2 monitored during a 6-month baseline period and followed for up to 36 months...

BACKGROUND: Lymphatic malformations (LMs) are low-flow congenital lesions that consist of cysts of varying size. Sclerotherapy with intralesional bleomycin and OK-432 has been reported to yield dramatically beneficial results for this disorder. However, inflammation-related symptoms are often seen after treatment with these sclerosing agents. On the other hand, polidocanol (POL) is reportedly associated with fewer allergic and inflammatory reactions. Up to now, however, very few reports have documented the use of POL microfoam for treatment of LMs...

OBJECTIVE: Anticoagulation remains the standard of care for line-associated upper extremity deep venous thrombosis (UEDVT). This treatment carries the risk of hemorrhagic complications, possibly more so in surgical patients. Considering the low-risk profile of UEDVT-which is associated with fewer, less severe pulmonary emboli than lower extremity deep venous thrombosis-current UEDVT treatment guidelines may be overly aggressive. The goal of this study was to review outcomes of line-associated UEDVT in critically ill patients and to define the efficacy of current treatment protocols in pulmonary embolism (PE) prevention while avoiding hemorrhagic complications...

OBJECTIVE: Current guidelines recommend thrombolytic therapy for iliofemoral deep venous thrombosis (DVT). Anticoagulation is the standard treatment for femoral-popliteal and tibial-level DVT. The objective of this study was to evaluate the efficacy of catheter-directed thrombolysis (CDT) using tissue plasminogen activator vs standard anticoagulation alone in patients with lower extremity DVT involving the femoral-popliteal segment. METHODS: A retrospective review was performed of patients referred to the vascular surgery service with lower extremity DVT from 2006 to 2015...

In this case report, we describe an unusual episode of bilateral submassive pulmonary embolism (PE) caused by a popliteal vein aneurysm (PVA). The development of PE stems from many risk factors including obesity (BMI³ 30 kg/m2), hypertension, cigarette smoking (greater than 25 cigarettes per day), increasing age, surgery, immobility, malignancy, and inherited thrombophilia. A PVA is a rare but significant cause of PE. A 28-year-old male presented to the emergency department with progressive shortness of breath...

Heparin has typically been used as a flushing or infusion solution for vascular lines in daily practice. However, several clinical trials have yielded controversial results about the benefits of heparin in maintaining peripheral venous catheters. The present meta-analysis was conducted to evaluate the efficacy of heparin on the patency profiles and complications in peripheral intravenous catheters. PubMed, Embase and Cochrane Central Register of Controlled Trials were searched up to February 2016 for randomized controlled trials comparing heparin with placebo in maintaining peripheral intravenous catheters...

Ultrasound (USG) guidance has long been used for guiding central venous catheterization. USG provides direct visualization of needle puncture through the skin into the vein. Most of the time USG guidance is just limited to puncturing of the vein and seeing guidewire entering the vein while malpositioning of catheter occurs after that which is seen later on while checking chest radiograph. Repositioning of catheter after that becomes not only difficult requiring repeated chest radiograph to reconfirm position of catheter but also increases chances of infection with repeated manipulations...

BACKGROUND: Many instruments for measurement of peripheral venous catheter (PVC)-related phlebitis are available, but no consensus exists on their applicability in clinical practice. This absence of consensus affects the ability to identify and compare proportions of PVCs causing phlebitis within and across hospitals as the range varies between 2% and 62% in previous studies. We hypothesised that the instruments' ability to identify phlebitis varies. The aim of this study is to illustrate the complexity of application of phlebitis instruments to a clinical dataset...

BACKGROUND Peripherally inserted central catheters (PICCs) are associated with central-line-associated bloodstream infections (CLABSIs). However, no tools to predict risk of PICC-CLABSI have been developed. OBJECTIVE To operationalize or prioritize CLABSI risk factors when making decisions regarding the use of PICCs using a risk model to estimate an individual's risk of PICC-CLABSI prior to device placement. METHODS Using data from the Michigan Hospital Medicine Safety consortium, patients that experienced PICC-CLABSI between January 2013 and October 2016 were identified...

BACKGROUND: Retained central venous catheter guidewires are never events. Currently, preventative techniques rely on clinicians remembering to remove the guidewire. However, solutions solely relying upon humans to prevent error inevitably fail. A novel locked procedure pack was designed to contain the equipment required for completing the procedure after the guidewire should have been removed: suture, suture holder, and antimicrobial dressings. The guidewire is used as a key to unlock the pack and to access the contents; thereby, the clinician must remove the guidewire from the patient to complete the procedure...
