OBJECTIVE: To present a simple and affordable model able to properly simulate an ultrasound-guided venous access. DESIGN: The simulation was made using a latex balloon tube filled with water and dye solution implanted in a thawed chicken breast with bones. RESULTS: The presented model allows the simulation of all implant stages of a central catheter. The obtained echogenicity is similar to that observed in human tissue, and the ultrasound identification of the tissues, balloon, needle, wire guide and catheter is feasible and reproducible...

It is difficult to treat a thrombotic embolism in the common femoral artery or popliteal artery (POP A), i.e., the non-stenting zone. We report a new technique for the treatment of thrombotic embolism in the non-stenting zone using a self-expandable nitinol stent. Case 1 had an external iliac artery (EIA) occlusion that occurred over several months. A self-expandable nitinol stent was placed in the right EIA lesion via a retrograde approach using a distal 9-Fr balloon protection guide catheter in the right femoral artery...

We report a case of percutaneous coronary intervention in a bifurcation lesion involving left circumflex (LCx) artery and 2 major posterolateral (PL) arteries. The target LCx had diffuse long and severely calcified lesion with the acute takeoff angle from the left main. Despite adequate lesion preparation with rotational atherectomy and balloon angioplasty, the stent was not deliverable, even with deep intubation of 7Fr-guiding catheter. Conventional use of guiding extension catheter (GEC) would have required removal of a wire from at least one PL because of the device interference in the GEC...

BACKGROUND: While the uptake of transradial access site is growing, there are concerns about associated radial injury. We report a feasibility study of a technique that enables both 5Fr diagnostic and PCI cases to be undertaken without an arterial sheath using conventional diagnostic and guide catheters with a modified balloon assisted tracking (BAT) technique. METHODS: We performed a prospective single center pilot study to assess the feasibility and effectiveness of sheathless radial artery access and BAT to perform coronary angiography and angioplasty using conventional 5 Fr diagnostic and guide catheters...

The use of balloon guide catheters in acute ischemic stroke intervention has been associated with improved reperfusion rates and clinical outcomes. This technique acts by promoting flow arrest and subsequent reversal to capture the thrombus debris that may be generated during the clot retrieval process. However, to the best of our knowledge, the use of BGC to remotely aspirate and remove intracranial thrombus has not been previously described. We report a three case series of patients with acute ischemic stroke from supraclinoidal internal carotid artery occlusions treated with remote aspiration thrombectomy through a BGC placed at the cervical internal carotid artery, leading to complete reperfusion without the need for intracranial catheterization...

Coronary stent delivery can be extremely challenging in tortuous and calcified lesions especially when radial approach is chosen. Guide extension catheter is a useful tool for overcoming the inherent difficulties arising by the use of radial access in complex percutaneous interventions. We describe a technique for guide extension catheter system advancement by presenting two cases. This was performed stepwise by repeated distal balloon anchoring in the coronary artery of interest.

PURPOSE: Pleural pressure measured with esophageal balloon catheters (Peso) can guide ventilator management and help with the interpretation of hemodynamic measurements, but these catheters are not readily available or easy to use. We tested the utility of an inexpensive, fluid-filled esophageal catheter (Peso) by comparing respiratory-induced changes in pulmonary artery occlusion (Ppao), central venous (CVP), and Peso pressures. METHODS: We studied 30 patients undergoing elective cardiac surgery who had pulmonary artery and esophageal catheters in place...

BACKGROUND: An intact pilot balloon assembly is crucial to the proper function of a cuffed tracheal tube. Disruption of the pilot balloon, transection of the inflation line, or valve incompetence results in cuff deflation, which may lead to inadequate ventilation and aspiration of secretions. Such failures typically result in tracheal tube replacement, but this may be a safety risk if a difficult reintubation is anticipated. We recently encountered such a patient who remained intubated postoperatively and in whom the inflation line was transected, causing a large leak...

Balloon dilation was performed in two Rottweiler puppies with cor triatriatum dexter and clinical signs of ascites using transthoracic echocardiographic guidance. The dogs were positioned on a standard echocardiography table in right lateral recumbency, and guide wires and balloon catheters were imaged by echocardiographic views optimized to allow visualization of the defect. The procedures were performed successfully without complications and clinical signs were resolved completely in both cases. Guide wires and balloon catheters appeared hyperechoic on transthoracic echocardiography image and could be clearly monitored and guided in real-time...

PURPOSE: Existing intraoperative radiation therapy (IORT) techniques are criticized for the lack of image guided treatment planning and energy deposition with, at times, poor resultant dosimetry and low radiation dose. We pioneered a novel method of IORT that incorporates customized, computed tomography (CT)-based treatment planning and high-dose-rate (HDR) brachytherapy to overcome these drawbacks: CT-HDR-IORT. METHODS AND MATERIALS: A phase 1 study was conducted to demonstrate the feasibility and safety of CT-HDR-IORT...

OBJECTIVE: Percutaneous coronary intervention (PCI) for the heavily calcified coronary lesions remains a challenge, and the periprocedural complication rates of the transfemoral approach are high. This study was conducted to investigate the feasibility and long-term results of the transradial approach for rotational atherectomy (RA) prior to stent implantation via the transradial approach in patients with heavily calcified coronary artery lesions. METHODS: RA followed by stent implantation via the transradial approach was performed in 47 patients with severely calcified coronary artery lesions in this retrospectively case-control study...

Coronary perforation (CP) is a rare but potentially lethal complication of percutaneous coronary intervention (PCI). Management of CP is mainly conditioned by the extension of coronary rupture and location of the perforation. Successful treatment is highly affected by the operator's familiarity with tools and dedicated techniques to achieve prompt sealing of the disruption. We describe a "Balloon-Microcatheter" technique that may allow fast, safe, and effective management of CP with a single ≥ 6 Fr guiding catheter...

BACKGROUND: Successful reopening of epicardial coronary artery does not always mean optimal myocardial reperfusion in a sizable portion of patients, mostly because of no-reflow phenomenon. OBJECTIVES: We investigated whether local injection of adrenaline ± verapamil in the distal coronary bed is more effective than their intracoronary (IC) injection through the guiding catheter in the treatment of no-reflow phenomenon following percutaneous coronary intervention (PCI)...

OBJECTIVE: Mechanical thrombectomy (MT) for acute intracranial internal carotid artery (ICA) occlusion is often complicated by difficult revascularization and non-involved territory embolization possibly related with larger clot-burden. This study aims to evaluate the efficacy of proximal aspiration thrombectomy (PAT) using a balloon-tipped guide catheter for clot-burden reduction in such cases with period-to-period analysis (period 1 : standard MT without PAT; period 2 : PAT first, then standard MT for the remaining occlusion)...

The surgical management of urinary stone disease developed substantially over the past decades and advanced minimally invasive techniques have been successfully introduced into clinical practice. Retrograde ureteroscopy and ureterorrenoscopy have become the first-line option for treatment of ureteral and renal stones worldwide with high success rates allied with a low morbidity profile. In this review, we will discuss some key points in ureteroscopy for stone disease, such as the access to upper urinary tract, including balloon and catheter dilation; how to choose and use some disposable devices (hydrophilic versus PTFE guide wires, ureteral catheters, and laser fiber setting); and lastly present and compare different techniques for kidney or ureteral stone treatment (dusting versus basketing)...

: Robotic level III inferior vena cava (IVC) tumor thrombectomy was described recently. We present ongoing robotic advances in this arena in a case series of six patients with Mayo level II-III thrombi who underwent robotic caval thrombectomy, radical nephrectomy, and retroperitoneal lymphadenectomy. In four patients, proximal intra- or retrohepatic IVC control was obtained solely with an intracaval Fogarty balloon catheter; in one patient, robot-guided flexible cystoscopy of the IVC lumen was performed to rule out any residual or secondary skip thrombi...

BACKGROUND: Radiofrequency ablation (RFA) of ventricular tachycardia (VT) can fail because of inaccessibility to the VT substrate. Transarterial coronary ethanol ablation can be effective but entails arterial instrumentation risk. We hypothesized that retrograde coronary venous ethanol ablation can be an alternative bail-out approach to failed VT RFA. METHODS AND RESULTS: Out of 334 consecutive patients undergoing VT/premature ventricular contraction ablation, 7 patients underwent retrograde coronary venous ethanol ablation...

A 78year old woman was admitted with an acute coronary syndrome. She underwent coronary angiography via the left radial artery which was complicated by a guide catheter induced radial artery perforation confirmed by extravasation of contrast into the forearm. We used balloon assisted tracking and guide catheter tamponade to complete the angioplasty procedure via the radial artery and successfully seal the radial artery perforation. We describe a series of 7 cases where this technique was used to both treat radial artery perforation and to complete the angioplasty via the radial approach...

Coronary artery bypass graft perforation during percutaneous coronary intervention is a rare complication. Perforation of a left internal mammary artery (LIMA) graft due to a guide catheter extension system has not been described. We report the successful deployment of a polytetrafluoroethylene (PTFE)-covered stent to seal the LIMA graft perforation due to the guide catheter extension system. Percutaneous coronary intervention was performed for a culprit lesion of the distal left circumflex via the LIMA graft...
