AIM: To investigate the success rates of endosonography (EUS)-guided biliary drainage (EUS-BD) techniques after endoscopic retrograde cholangiopancreatography (ERCP) failure for management of biliary obstruction. METHODS: From Feb/2010 to Dec/2016, ERCP was performed in 3538 patients, 24 of whom (0.68%) suffered failure to cannulate the biliary tree. All of these patients were initially submitted to EUS-guided rendez-vous (EUS-RV) by means of a transhepatic approach...

OBJECTIVES: Double-guidewire cannulation (DGC) for selective biliary access has been associated with increased risk of post-ERCP pancreatitis (PEP) in patients who have had pancreatic duct (PD) contrast injection. The objective of this study was to determine whether DGC increases PEP risk in standard risk individuals when controlling for procedural aspects such as PD contrast injection. METHODS: Consecutive adults with native papillae who underwent endoscopic retrograde cholangiopancreatography from 2009 to 2014 were retrospectively identified, and clinical data were collected...

We report a novel technique for retrieving an entrapped Gaia guidewires in severely calcified coronary chronic total occlusion (CTO) using a rotational atherectomy device. By successfully cutting the entrapped and untangled guidewire within the CTO with the use of a rotational atherectomy device, we could effectively remove the Gaia guidewire from the right coronary artery.

AIMS: We occasionally experience endovascular therapy (EVT) failure as a consequence of wire-crossing into the subintima for chronic total occlusion (CTO) in peripheral arteries. Although several reports have demonstrated the importance of accurate wire-crossing into the ostial site of the CTO true lumen to succeed, it is difficult to visualize the CTO ostium before wiring using angiography or intravascular ultrasonography (IVUS). Thus, we directly visualize the ostial sites of lesions and wire manipulation during EVT by angioscopy and evaluate the efficacy and safety of angioscopy-guided EVT under continuous infusion of saline (AGECIS) in peripheral arteries...

BACKGROUND: The successful recanalization rate of chronic total occlusion (CTO) lesions without retrograde collaterals available is always low. Intravascular ultrasound (IVUS) may be useful to guide the subintimal guidewire to re-enter the true lumen. We evaluated the clinical feasibility and efficacy of the IVUS-guided wiring re-entry technique for these complex CTO lesions. METHODS: Twenty consecutive patients (19 male, mean age: 65.3 ± 12.8 years) with both failed antegrade and retrograde approaches were enrolled...

Intra-abdominal injury is an uncommon complication of chest tube insertion. A 66-year-old man had empyema and underwent chest tube insertion for drainage. Massive hemorrhage occurred; the postprocedural radiograph showed the malpositioned chest tube in the mediastinum. Computed tomography scan showed that the tube's tip penetrated through the liver capsule and passed through the hepatic vein to the right ventricle. Hepatic tract embolization with coiling was performed during chest tube removal under a controlled condition with the hepatic tract occluded by a balloon catheter...

AIM: To compare the cannulation success, biochemical profile, and complications of the papillary fistulotomy technique vs catheter and guidewire standard access. METHODS: From July 2010 to May 2017, patients were prospectively randomized into two groups: Cannulation with a catheter and guidewire (Group I) and papillary fistulotomy (Group II). Amylase, lipase and C-reactive protein at T0, as well as 12 h and 24 h after endoscopic retrograde cholangiopancreatography, and complications (pancreatitis, bleeding, perforation) were recorded...

Lumen vessel sizing is important for optimization of interventional outcomes for treatment of vascular disease. The objective of this study is to develop an injection-less method to determine the lumen diameter, using multiple frequencies that eliminates the need for saline injections. We utilize the same electrical conductance devices developed for the two-injection method. A mathematical electrical model was devised to estimate the lumen area and diameter of the arteries. In vitro experiments were used to validate the method for various lumen diameters with both 5-5-5 (peripheral) and 2-2-2 (coronary) spacing conductance guidewires...

Collagen has been extensively used as a biomaterial, yet for tubular organ repair synthetic polymers or metals (e.g. stents) are typically used. In this study we report a novel type of tubular implant solely consisting of type I collagen, suitable to self-expand in case of minimal invasive implantation. Potential benefits of this collagen scaffold over conventional materials include improved endothelialization, biodegradation over time and possibilities to add bioactive components to the scaffold, such as anti-coagulants...

INTRODUCTION: With increasing use of percutaneous vascular procedures, access complications that present to a vascular surgeon increase. The most limb-threatening condition is acute limb ischaemia. Acute limb ischaemia is the most common vascular surgical emergency. In spite of recent advances in vascular surgery, it continues to carry a poor prognosis, if not early diagnosed and managed. METHODS: This is a case-report of 2 patients referenced to a vascular surgery emergency department of a tertiary hospital with late acute limb ischaemia...

BACKGROUND: Endoscopic ultrasound-guided hepaticojejunostomy (EUS-HJS) combined with antegrade stenting (AS) can proceed if patients are complicated with duodenal obstruction or surgical anatomy such as Roux-en-Y esophagojejunostomy. A novel plastic stent (Gadelius Medical Co. Ltd., Tokyo, Japan) that is designed to prevent stent migration into the abdominal cavity was made available in Japan. Here, we describe technical tips for EUS-HJS combined with EUS-AS using this plastic stent. TECHNICAL PRESENTATION: After the intrahepatic bile duct is punctured, the guidewire is inserted into the intestine across the bile duct obstruction site...

The right internal jugular vein (IJV) is an important access site for hemodialysis catheterization. Venous cannulation failure is usually caused by central venous stenosis and is rarely related to vessel malformation. We herein present a case of failure to place a tunneled hemodialysis catheter into the right IJV. The patient had an arteriovenous fistula in the right arm with inadequate flow and a history of multiple central venous catheterizations. The guidewire was repeatedly misplaced into the right subclavian vein (SV) regardless of the technique used...

Currently, there are more opportunities to treat patients complicated with critical limb ischemia (CLI), which is a very dismal medical condition associated with a high risk of major amputation, disability and death. Because CLI is usually caused by multi-level occlusive atherosclerotic disease, the condition of CLI induced by aorto-iliac occlusive disease (AIOD) alone is thought to be a rare pathological entity. We encountered a patient with severe CLI caused by solitary AIOD. Three vascular access routes were established and stiff guidewires retrogradely passed the occluded arteries on both sides...

There is an increasing rivalry between percutaneous transhepatic (PTBD) vs. endoscopic ultrasound-guided biliary drainage (EUS-BD) as rescue techniques after failed endoscopic retrograde cholangiography (ERC) access. While EUS-BD procedures hold a bright future, innovations in PTBD technique are still possible and clinically meaningful, at least so, under the a conceptual framework understanding PTBD as a bridging, anatomy-respecting technology for definitive biliary metal stenting. This, however, calls for successful PTBD internalization as a sine qua non...

BACKGROUND: Risk factors for postoperative cognitive decline after noncardiac surgery are multifactorial and poorly understood. Evidence suggests that perioperative microembolic damage to the brain on movement of wires and catheters during endovascular aortic procedures may play an important role. Endovascular aortic aneurysm repair requires invasive manipulation of wires and cannulas within the aorta, but research into cerebral emboli during aortic aneurysm repair and cognitive or neurologic injury is scarce and limited to thoracic aneurysms...

Endovascular reconstruction for carotid artery dissection (CAD) involving a highly tortuous segment of the cervical internal carotid artery (ICA) is challenging because the tortuous ICA may preclude navigation of large-profile carotid stents. Successful recanalization using low-profile neurostents has been reported in small case series only. We herein describe two patients with CAD of a tortuous segment who were successfully treated with large-profile carotid stents after straightening the ICA with a stiff peripheral microguidewire...
