BACKGROUND: Heparin saline (HS) is theoretically superior to normal saline (NS) for maintaining the patency of central venous catheters (CVCs), but the comparative efficacy of them remains controversial. The aim of this systematic review and meta-analysis was to assess the efficacy of NS versus HS in the maintenance of the patency of CVCs in adult patients. METHODS: We searched PubMed, Embase and the Cochrane library databases. Randomized controlled trials (RCTs) evaluating the use of NS vs...

Seung Kwon Kim, Bryan G Belikoff, Carlos J Guevara, Seong Jin Park
We propose an algorithm for management after transjugular intrahepatic portosystemic shunt (TIPS) placement according to clinical manifestations. For patients with an initial good clinical response, surveillance Doppler ultrasound is recommended to detect stenosis or occlusion. A TIPS revision can be performed using basic or advanced techniques to treat stenosis or occlusion. In patients with an initial poor clinical response, a TIPS venogram with pressure measurements should be performed to assess shunt patency...

PURPOSE: Multi-phase post-mortem computed tomography angiography (MPMCTA) is a new diagnostic tool, used in forensic pathology. On the one hand, this technique allows a better and direct visualization of vascular and solid organ lesions. On the other hand, the invasiveness of the procedure-which requires surgical denudation (inguinal and/or cervical) and the insertion of surgical cannulas-leads to many relatives refusing scientific autopsies. Our hypothesis states that a minimally-invasive procedure combining interventional radiological techniques with MPMCTA (replacement of surgical cannulas by radiological catheters) will improve the approval rate of scientific autopsies by families...

Chronic Mesenteric Ischemia (CMI) presenting as acute abdomen can be treated percutaneously. An endovascular intervention has surpassed surgical revascularization over the past decade due to its lesser perioperative complication rate. Trans-femoral approach of revascularising is limited by its difficulty in coaxial alignment of the guiding catheter and hence, brachial artery and recently the radial approach have been utilized for mesenteric artery revascularisation for over a decade. Here by we report a case of chronic mesenteric ischemia having total occlusion of two and 70% occlusion of one of the three mesenteric vessels...

BACKGROUND: The incidence of contrast-induced acute kidney injury is strongly related to the amount of the given contrast. Our objectives were to evaluate the efficacy and safety of coronary sinus aspiration (CSA) procedure to reduce the volume of the given contrast and attenuate the risk of contrast-induced acute kidney injury. METHODS AND RESULTS: The study included 43 patients with type 2 diabetes mellitus and renal impairment (creatinine 1.5-3 mg/dL) who were candidates for coronary angiography...

INTRODUCTION: Peripheral venous catheters (PVC) are medical devices most frequently used during hospital care. Although the frequency of specific PVC-related adverse events (PVCAEs) has been reported, the global risk related to the insertion of this device is poorly estimated. The aim of this study is to determine the incidence of PVCAEs during the indwell time, after catheter removal, and to identify practice-mirroring risk factors. METHODS: A prospective observational study was conducted as a part of a research project, called CATHEVAL, in one surgery ward and four medicine wards from three public general tertiary care hospitals in Northern France that were invited to participate between June-2013 and June-2014...

BACKGROUND: Neonatal intensive care units (NICUs) commonly utilize peripherally inserted central catheters (PICCs) to provide nutrition and long-term medications to premature and full-term infants. However, little is known about PICC practices in these settings. PURPOSE: To assess PICC practices, policies, and providers in NICUs. METHODS: The Neonatal PICC1 Survey was conducted through the use of the electronic mailing list of a national neonatal professional organization's electronic membership community...

OBJECTIVES: Percutaneous ostium secundum atrial septal defect (ASD II) closure has become the standard of care for treatment of congenital ASD II in adults. Nevertheless, patients are frequently ineligible for this technique due to challenging morphology. In such cases, closure via minimally invasive cardiac surgery (MICS) is an appropriate treatment option. The aim of this study is to compare outcomes of MICS and use of a percutaneous Amplatzer septal occluder (ASO) device for treatment of ASD II in adults...

A 56-year-old male Patient presented 27 days after a liver transplantation (LT) with fever and hyperbilirubinemia. He underwent CT examination resulting in a diagnosis of right hepatic artery (HA) occlusion with hepatic bilomas. Once placed a long right femoral 6F introducer at the origin of the HA, a 0.014" guidewire was advanced over the thrombus, in a segmental branch. A 4MAX (Penumbra, Alameda, USA) catheter was advanced and withdrawn under constant aspiration until complete clot removal was achieved. Follow-up CT and D-US assessments at 12 months demonstrated regular HA patency and bilomas reduction...

Modern, minimally invasive techniques used to treat deep venous thrombosis, such as percutaneous mechanical thrombectomy (PMT) and catheter-directed thrombolysis, have gained worldwide acceptance. PMT has the advantage of speed and is also associated with improved outcomes, shortened hospital stays, and low complication rates. The main complications associated with PMT have been primarily due to iatrogenic vascular damage resulting in perforation, embolic occlusion, and arteriovenous fistula formation; to date, there has been no publication in the literature describing complications resulting from device failure...

OBJECTIVES: The aim of this study was to directly compare the hemodynamic effects of 2 contemporary percutaneous mechanical circulatory support devices in a porcine model of acute myocardial infarction. BACKGROUND: Percutaneous support devices offer the ability to unload the ischemic left ventricle, but the comparative hemodynamic effects of contemporary platforms are unclear. METHODS: Yorkshire swine (mean weight 76 ± 2 kg; n = 7) were instrumented with a left ventricular (LV) pressure-volume (PV) catheter and subjected to a 2-h coronary occlusion...

Bleeding gastric varices (GV) are managed by cyanoacrylate glue injection with transjugular intrahepatic portosystemic shunt (TIPSS) as modality for treatment failure. Ulcer can form at the site of glue injection over GV and it can cause bleeding. Treatment approach for such bleed is not well described. Balloon-occluded retrograde transvenous obliteration (BRTO), TIPSS, and devascularization remain the treatment options in this scenario. BRTO is an endovascular procedure where a balloon catheter is inserted into a draining vein of GV, and the sclerosant can be injected into the varices through the catheter during balloon occlusion...

Calcium and iron overload participate in the mechanisms of ischemia/reperfusion (I/R) injury during myocardial infarction (MI). Calcium overload induces cardiomyocyte death by hypercontraction, while iron catalyses generation of reactive oxygen species (ROS). We therefore hypothesized that dexrazoxane, an intracellular metal chelator, would attenuate I/R injury. MI was induced in pigs by occlusion of the left anterior descending artery for 1 hour followed by 2 hours reperfusion. Thirty minutes before reperfusion either 5 mg/ml dexrazoxane (n = 5) or saline (n = 5) was infused intravenously...

BACKGROUND: Reperfusion of large vessel occlusions in acute stroke can improve patient outcomes. The purposes of this study were to assess the safety and efficacy of the Penumbra 5MAX ACE catheter for revascularization of large vessels and to compare its cost to the cost of stent retrievers. METHODS: In this retrospective, single-center case review study, data were captured on consecutive patients treated with the Penumbra 5MAX ACE as first-line therapy during an 11-month period...

INTRODUCTION: The direct aspiration first pass technique (ADAPT) has been introduced as a rapid and safe endovascular treatment strategy in patients with ischemic stroke. OBJECTIVE: To determine the technical feasibility, safety, and functional outcome with ADAPT using the new large-bore 6F SOFIA Plus catheter. METHODS: A retrospective analysis of prospectively collected data from six university hospitals was performed. The following parameters of all acute stroke procedures (June 2015- January 2016) using the SOFIA Plus catheter were analyzed: accessibility of the thrombus with the catheter, recanalization success (Thrombolysis in Cerebral Infarction ≥2b), time to recanalization, procedure-related complications...
