Transvenous embolization is an effective method for treating dural arteriovenous fistulas (DAVFs) of the transverse-sigmoid sinus (TSS). However, in cases of complicated DAVFs, it is difficult to preserve the patency of the dural sinus. The authors describe the technical details of a new reconstructive technique using transvenous balloon-assisted Onyx embolization as another treatment option in a patient with an extensive and complex DAVF of the left TSS. A microcatheter and compliant balloon catheter were navigated into the left internal jugular vein and placed at the distal end of the DAVF in the transverse sinus...

BACKGROUND: Percutaneous procedures to treat common bile duct (CBD) stones typically require access via intrahepatic bile ducts. This study aimed to describe the outcomes of a percutaneous transcystic approach that expelled the CBD stones into the duodenum after percutaneous transcystic balloon dilation of the ampulla (PTCBDA) for high-risk patients who present with acute cholecystitis and CBD stones. METHODS: Patients diagnosed with acute cholecystitis and CBD stones who were deemed too high-risk for surgery or general anesthesia and were treated with PTCBDA and CBD stone removal between March 2010 and November 2015 were included for further analysis...

PURPOSE: Balloon Eustachian tuboplasty (BET) is a new treatment modality addressing chronic obstructive dysfunction of the Eustachian tube (ET). So far, BET has been deemed a safe procedure under general anesthesia with only minor adverse effects. However, individual cases of postoperative emphysema have been reported. In the present retrospective multicenter analysis we determined the incidence rate of this potentially life threatening complication after BET. METHODS: In total we collected data from 3,670 BET procedures performed on 2,272 patients in four tertiary care ENT departments...

Background: Central venous oxygen saturation (ScvO2) reflects the balance of oxygen delivery and consumption. Low ScvO2 indicates the presence of inadequate oxygen delivery, while high ScvO2 indicates reduced oxygen consumption and is sometimes associated with a high mortality rate in critically ill patients from dysoxia. Thiamine is an essential cofactor in cellular aerobic metabolism. Thiamine deficiency is more prevalent than was previously thought, and underlies severe conditions in critically ill patients...

In neonates requiring balloon aortic valvuloplasty, both anterograde and retrograde approaches are feasible. A recent comparison of these two approaches is lacking. A retrospective cohort study of neonates at a single center undergoing BAV from 9/00 to 7/14 was performed. Records were reviewed including pre- and post-intervention echocardiograms and catheterization data. Comparisons of acute efficacy and procedural safety were made based on type of approach utilized. Forty-two neonates underwent BAV. Eleven cases utilized exclusively an anterograde approach, while 31 included a retrograde approach (including 4 with both approaches used)...

Background Intracranial atherosclerotic disease may result in ischemic infarction and has a high rate of recurrent ischemic strokes despite medical therapy. Patients who fail medical therapy may undergo endovascular treatment with cerebral artery angioplasty and possible Wingspan stent placement. We present a unique case of Wingspan delivery microcatheter fracture that resulted in a retained foreign body and an endovascular salvage maneuver. Case description An elderly patient presented with an acute ischemic stroke due to a severe stenosis in the proximal left middle cerebral artery (MCA)...

Hemoptysis may occur in patients with pulmonary venous obstruction and prominent decompressing vessels in the airways adjacent to the affected pulmonary veins. The options for treatment of hemoptysis are limited, particularly when efforts to alleviate pulmonary venous obstruction have failed. Here we describe a patient with hemoptysis associated with stenosis of the central left upper pulmonary vein and occlusion of the central left lower pulmonary vein. The left upper pulmonary vein was dilated with balloon catheters and a vascular plug was placed in the left lower pulmonary artery...

AIMS OF THE STUDY: Induction of labour after previous caesarean section (CS) is a challenge for obstetricians due to the increased risk of uterine rupture. Common methods for labour induction are balloon catheters and oxytocin as they are considered safe. However, the effectiveness remains unclear as currently available data are limited. Therefore, we aimed to determine safety and effectiveness of balloon catheter or oxytocin for labour induction after CS. METHODS: We included 179 consecutive women with a previous CS and labour induction in this retrospective study...

OBJECTIVE: Urethral stenosis is a disease in which the lumen of the urethra becomes constricted by fibrosis. Such stenoses have been treated by urethral dilation using a bougie and optical internal urethrotomy (OIU). Recently, high-pressure balloon dilation (BD) has been developed as a new treatment method for urethral stenosis. The present study compared the effectiveness of urethral dilation by BD and OIU. METHODS: Twenty-two patients of urethral stenosis were treated at Yokohama City University Medical Center between 2005 and 2015...

Percutaneous coronary intervention for bifurcated anatomy, particularly at the proximal left coronary artery site, requires guide catheters (GC) of at least 6 french and preferably larger in diameter. We describe a new trans-radial approach more suitable for small artery size: the simultaneous use of both radial arteries for double cannulation of the LMCA with 5F GC: each GC will target either the LM/LAD or the LM/CX artery (or LM-LAD/LM-LAD-1st diagonal branch) stenoses. The technique successfully was applied to 5 cases...

Intravascular ultrasound (IVUS) is mainly used in PCI to treat complex lesions, such as left main bifurcation, chronic total occlusion and calcified lesions. Although IVUS yields useful information such as the presence of napkin-ring calcification, the role of IVUS in rotational atherectomy (RA) is not fully appreciated. Recently, since the deliverability and crossability of IVUS catheters have improved, IVUS should be attempted before RA. Even if the IVUS catheter cannot cross the lesion, IVUS provides information just proximal to the target lesion, which would be useful in the selection of the appropriate guidewire and burr size...

Occlusion balloon catheters of 5.2- or 6-French have been used for a few decades in various endovascular treatments of body trunk vascular lesions. However, these catheters may be difficult to place in cases of excessive vessel tortuosity, small vessels, and anatomic complexity. Recently, the introduction of the double lumen microballoon catheters for body trunk vascular lesions has allowed operators to advance them into more distal, smaller, and more tortuous vessels. Since the launch of the first generation microballoon catheters onto the market in Japan in 2011, the microballoon catheters have evolved and are now generally available for clinical use...

Dislodged intrabiliary drainage devices, including catheters, endoprostheses, and stents, may further impair drainage and cause various local reactions, vascular and gastrointestinal tract complications. Endoscopic approaches for management of plastic biliary endoprostheses have been extensively discussed. However, in rare cases of fracture of percutaneous transhepatic biliary drainage (PTBD) catheters, only a percutaneous transhepatic technique for retrieving should be applied to avoid further damage by its rigid fragment...

BACKGROUND AND STUDY AIMS:  Endoscopic papillary balloon dilation (EPBD) is a method of bile duct stone removal that has a better long-term outcome but a high risk of post-ERCP pancreatitis (PEP). Recent studies have suggested that 5-minute EPBD can reduce the incidence of PEP. This study aimed to examine the safety and effectiveness of longer duration EPBD compared with shorter duration EPBD (5 minutes vs. 15 seconds after disappearance of the waist of a dilation catheter). PATIENTS AND METHODS:  Patients without a history of endoscopic sphincterotomy or EPBD who underwent EPBD to remove bile duct stones were selected retrospectively from five centers...
