BACKGROUND: Our initial experience using the two-stage aspiration technique (TSAT) with proximal flow arrest by a balloon guiding catheter is presented. In TSAT, aspiration is applied with the 5MAX ACE and also with the 3MAX catheter with a Penumbra aspiration pump, while arresting proximal flow by balloon inflation. METHODS: In patients treated with TSAT, clinical data including National Institutes of Health Stroke Scale (NIHSS) score at admission and the modified Rankin Scale (mRS) score at discharge, as well as procedural data including the Thrombolysis in Cerebral Infarction (TICI) score, procedural time, and complications were analyzed...

Dissection of the internal carotid artery (ICA) is a rare condition that accounts for a significant proportion of ischemic strokes in young adults. Iatrogenic dissection as a complication of neurointerventional procedures is a traumatic dissection which has been reported relatively rare in the literature. In this report, a case of dissection of the ICA is reported that was caused by repetitive movement of the balloon guiding catheter during stent-assisted thrombectomy (SAT), resulting in occlusion of the ICA...

Stent-grafts are widely used for the treatment of various conditions such as aortic lesions, aneurysms, emboli due to coronary intervention procedures and perforations in vasculature. Such stent-grafts are manufactured by covering a stent with a polymer membrane. An ideal stent-graft should have a biocompatible stent covered by a porous, thromboresistant, and biocompatible polymer membrane which mimics the extracellular matrix thereby promoting injury site healing. The goal of this protocol is to manufacture a small caliber stent-graft by encapsulating a balloon expandable stent within two layers of electrospun polyurethane nanofibers...

We encountered a case of blow-out type coronary perforation at the calcified stenosis of left anterior descending artery. First, we started immediate balloon tamponade through the initial guiding catheter (GC) with a GuideLiner(®) catheter. Next, we introduced a second GC with a GuideLiner(®) catheter and successfully deployed a covered stent. Two sets of the GC with GuideLiner(®) catheter facilitated us to simultaneously perform temporary hemostasis with balloon tamponade and rapid delivery of a covered stent...

Plaque rupture causes acute coronary syndromes and stroke. Intraplaque oxidized low density lipoprotein (oxLDL) is metabolically unstable and prone to induce rupture. We designed an intravascular ultrasound (IVUS)-guided electrochemical impedance spectroscopy (EIS) sensor to enhance the detection reproducibility of oxLDL-laden plaques. The flexible 2-point micro-electrode array for EIS was affixed to an inflatable balloon anchored onto a co-axial double layer catheter (outer diameter = 2 mm). The mechanically scanning-driven IVUS transducer (45 MHz) was deployed through the inner catheter (diameter = 1...

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...

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)...
