PURPOSE: To describe a maneuver to facilitate percutaneous arteriovenous fistula creation during venous arterialization procedures in patients with no-option critical limb ischemia. TECHNIQUE: Following a failed arterial recanalization attempt, a balloon catheter is passed up to the tip of the guidewire. Venous access is gained distally, a 4-F sheath is antegradely passed, and a 4-mm GooseNeck snare is advanced through it. A fluoroscopic view that overlaps the snare and the inflated balloon is obtained...

INTRODUCTION: Stent retriever combined with aspiration, or the 'Solumbra technique', has recently emerged as one of the popular methods of mechanical thrombectomy (MT). However, the variations in understanding and implementation of the Solumbra technique have not been reported. METHODS: An 18 part anonymous survey questionnaire was designed to extract information regarding technical variations of MT with a focus on the Solumbra technique. The survey link was posted on the Society of Neurointerventional Surgery (SNIS) website in 'SNIS connect'...

Prostaglandins and intracervical catheters are similarly effective for cervical ripening and for an induction of labour (IOL). Studies comparing the combined use with either method alone have administered repetitive doses of prostaglandins vaginally, which may increase the risk of tachysystole and chorioamnionitis. These disadvantages may be offset by co-administering a single dose of prostaglandin. Women (n = 110) planned for IOL, ≥37 weeks of gestation and with a Bishop Score of ≤6 were randomised into two groups: intracervical Foley catheter alone or combined with dinoprostone gel (0...

OBJECTIF: Balloon catheters for labor induction at term after previous cesarean section is an alternative option to iterative cesarean section. The aim of this study was to analyze the maternal and neonatal outcomes of the trial of labor after cesarean (TOLAC) in women with unfavorable cervix and balloon catheter induction, 2 years after introduction of this process. METHODS: Unicentric observational study of women with term cephalic singleton, unfavorable cervix (simplified Bishop score<5) after TOLAC using double-balloon catheter...

BACKGROUND: Abernethy malformation is an extremely rare congenital malformation characterised by an extrahepatic portosystemic shunt. Children with Abernathy malformation can develop hepatopulmonary syndrome (HPS) with pulmonary arteriovenous fistulas (PAVF) or pulmonary hypertension. PAVF manifests as central cyanosis with effort intolerance. We report a case of PAVF in a Ten-year-old Boy. Persistent symptoms identified Abernathy malformation as the cause of progressive symptoms and current understanding of this rare malformation is reviewed...

OBJECTIVE: To compare the effect of misoprostol combined with a cervical single or double-balloon catheter versus misoprostol alone for labor induction of singleton pregnancies with an unfavorable cervix. METHODS: Systematic review and meta-analysis of randomized controlled trials (RCTs) regarding the comparison of two schemes for labor induction of singleton cephalic pregnancies with a Bishop score ≤7 and no contraindication for vaginal delivery. Six research databases were searched for articles published in all languages up to 10 May 2018 comparing misoprostol (oral or vaginal) in combination with a cervical placed single or double balloon catheter versus misoprostol treatment alone...

OBJECTIVES: To describe the efficacy and safety of stent-retriever thrombectomy in infants with thrombosis of the superior vena cava (SVC) and innominate vein. BACKGROUND: Thrombosis of the SVC and of the innominate vein is a potentially life threatening complication in infants during intensive care treatment following major surgical procedures. To avoid reoperations, we evaluated interventional revascularization by stent-retriever thrombectomy. METHODS: From 2015 to 2017, five infants were diagnosed with acute thrombosis of the SVC and innominate vein following major cardiac or pediatric surgery...

INTRODUCTION: The use of intragastric balloons (IGB) for the treatment of obesity has been increasing significantly, with data confirming its effectiveness with low complication rates. Adjustable balloons are not widely available for use in all countries, including the USA. In this video, we demonstrate a unique technique in which a conventional nonadjustable balloon is modified to an adjustable balloon to improve weight loss. METHODS: A 35-year-old woman with a BMI of 36...

BACKGROUND: The Swan-Ganz catheter is a reliable method used to monitor hemodynamics in intensive care units. Pump-controlled retrograde trial off is a new weaning test for veno-arterial extracorporeal membrane oxygenation in recent years. The objective of this report is to describe a case in which pulmonary artery flotation catheter hemodynamic monitoring in combination with pump-controlled retrograde trial off was sufficient for veno-arterial extracorporeal membrane oxygenation weaning...

A variety of pathologies lead to pulmonary hypertension (PH), which is defined as a mean pulmonary artery pressure exceeding 25 mmHg at rest. To further diagnose and manage PH, patients undergo repeated right heart catheterizations (RHC) wherein a Swan-Ganz catheter is advanced into a branch of the pulmonary artery and a balloon is inflated to wedge the catheter tip. This article illustrates a protocol whereby pulmonary artery endothelial cells (PAECs) may be harvested from the balloon tips of Swan-Ganz catheters after RHC, and purified with an anti- CD146 affinity column technique to purify putative PAECs...

Restrictions on the conventional evaluation of diastolic function has been recognized especially under various loading conditions. Recently, new noninvasive ventricular vortex indexes have been introduced and are expected to reflect the cardiac function. Physiologically, there is a hypothesis that intraventricular pressure difference (IVPD) is related to the formation of vortexes. IVPD and the vortex indexes were simultaneously measured and the relationship between the two was investigated. To verify the possibility of diastolic vorticity as an index of diastolic relaxation, a correlation between diastolic vorticity and Tau, load dependency of vorticity was examined...

Balloon-occluded transarterial chemoembolisation (B-TACE) is an intraarterial transcatheter treatment for liver cancer. In B-TACE, an artery-occluding microballoon catheter occludes an artery and promotes collateral circulation for drug delivery to tumours. This paper presents a methodology for analysing the haemodynamics during B-TACE, by combining zero-dimensional and three-dimensional modelling tools. As a proof of concept, we apply the methodology to a patient-specific hepatic artery geometry and analyse two catheter locations...

INTRODUCTION: When women with a previous cesarean section and an unfavorable cervix have an indication for delivery, the choice is to induce labor or perform a cesarean section. This study aims to assess the effectiveness and safety of a balloon catheter as method of induction of labor in women with one previous cesarean section and an unfavorable cervix compared to an elective repeat cesarean section. MATERIAL AND METHODS: We performed a prospective cohort study in 51 hospitals in the Netherlands on term women with one previous cesarean section, a live singleton fetus in cephalic position, an unfavorable cervix and an indication for delivery...

BACKGROUND: Current guidelines for the treatment of Clostridium difficile infections (CDIs) recommend vancomycin enemas for patients with adynamic ileus. There is significant variability in guideline recommendations for vancomycin dose and enema volume and whether a retention enema should be used. The most recent (2017) guidelines from the Infectious Diseases Society of America/Society for Healthcare Epidemiology of America recommend rectal instillation of 500 mg of vancomycin in 100 mL of physiologic saline every 6 hours as a retention enema...

INTRODUCTION: The Solitaire stent retriever registry showed improved reperfusion, faster procedure times, and better outcome in acute stroke patients with large vessel occlusion treated with a balloon guide catheter (BGC) and Solitaire stent retriever compared with a conventional guide catheter. The goal of this study was to evaluate whether use of a BGC with the Trevo stent retriever improves outcomes compared with a conventional guide catheter. METHODS: The TRACK registry recruited 23 sites to submit demographic, clinical, and site adjudicated angiographic and outcome data on consecutive patients treated with the Trevo stent retriever...
