A 58-year-old man was admitted due to a 4-month history of colicky right upper quadrant pain, intermittent fever, anorexia and weight loss. A contrast-enhanced CT scan of the abdomen showed an encapsulated, peripherally enhancing focus occupying the right liver lobe exhibiting capsular rupture and extension to the walls of the hepatic flexure. He immediately underwent emergency ultrasound-guided percutaneous catheter drainage and cultures of the purulent fluid later revealed Escherichia coli A colonoscopy was then performed which showed a pinpoint opening with draining pus at the hepatic flexure...

Joren Maeremans, Pieter-Jan Palmers, Joseph Dens
BACKGROUND During antegrade dissection re-entry (ADR) of chronic total occlusions (CTO), the first-generation Stingray catheter requires the use of large-bore guides (sheathless 7.5 Fr or 8 Fr), which increases the risk for access site-related complications and compromises radial approaches. Smaller guiding sizes necessitate long guidewires (e.g., 300 cm) or guidewire extensions for catheter advancement or removal. However, friction between guides and the Stingray catheter can result in unstable guidewire position or unintentional removal...

BACKGROUND: Endovascular recanalization of a completely occluded proximal internal carotid artery (ICA) with underlying stenosis may be challenging owing to a possible thrombotic component. This is especially true when the landing zone for a balloon-tipped guiding catheter (BGC) at the bulb portion is insufficient. Sequential application of the balloons of a BGC and an angioplasty catheter may prevent thromboembolism during revascularization. This study analyzed the safety and effectiveness of this relay-balloon technique...

Identifying the site of vascular bleeding in fatal cases of traumatic basal subarachnoid hemorrhage (TBSAH) is important, but can be very difficult to achieve when there is extensive blood clot in the posterior cranial fossa. Post mortem angiography in these circumstances has been reported previously but with mixed results, and is rarely used in current practice within the United Kingdom. We have developed a simple and effective post mortem angiography method, using fluoroscopy and clear modern contrast medium, suitable for use in the autopsy room...

An 86-year-old female patient with a history of bypass surgery was admitted for recurrent dyspnea and chest pain on exertion. She underwent coronary angiography showing high-grade saphenous vein graft stenosis supplying the right coronary. During an attempt to perform percutaneous intervention, saphenous vein graft to the right coronary artery was injured by the guide catheter resulting in dissection with thrombus formation but with normal distal blood flow. The procedure was abandoned since she had normal distal flow and also due to a fear of causing extension of the dissection with further manipulation...

It is difficult to treat large internal carotid aneurysms with simple surgical clipping. Here, we present a retrograde suction decompression (RSD) procedure for large internal carotid aneurysms using a balloon guide catheter combined with a blood-returning circuit and a superficial temporal artery to middle cerebral artery (STA-MCA) bypass.All patients underwent an STA-MCA bypass before the temporary occlusion of the internal carotid artery (ICA). A 6-French sheath was inserted into the common carotid artery (CCA), and a 6-French Patrive balloon catheter was placed into the ICA 5 cm past the bifurcation...

BACKGROUND: Percutaneous coronary intervention (PCI) procedures are increasingly performed on complex tortuous and heavily calcified coronary lesions. The GuideLiner® catheter (Vascular Solutions, Inc. Minneapolis, MN) is a rapid exchange guide catheter extension system. There is paucity of data about the efficacy of this device in complex PCI. Therefore, we aim to report the indications, success, and efficacy of GuideLiner use in treating complex lesion subset in the present study. METHODS: We collected data from all patients in whom the GuideLiner was used to facilitate PCI between April 1, 2011 and December 31, 2014 at a tertiary referral center in Toronto, Canada...

In minimal invasive image guided catheterization procedures, physicians require information of the catheter position with respect to the patient's vasculature. However, in fluoroscopic images, visualization of the vasculature requires toxic contrast agent. Static vasculature roadmapping, which can reduce the usage of iodine contrast, is hampered by the breathing motion in abdominal catheterization. In this paper, we propose a method to track the catheter tip inside the patient's 3D vessel tree using intra-operative single-plane 2D X-ray image sequences and a peri-operative 3D rotational angiography (3DRA)...

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...

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.

Surgical patients with pulmonary hypertension present a significant challenge to the anesthesiologist. Continuous perioperative monitoring of pulmonary artery (PA) pressure is recommended and most often accomplished with a PA catheter. Placement of a PA catheter may be difficult or contraindicated, and in these cases, transesophageal echocardiography is a useful alternative to monitor dynamic PA physiology. In this case, we used intraoperative transesophageal echocardiography to detect changes in peak PA pressure and guide clinical treatment in a patient with pulmonary hypertension and an extensive PA aneurysm undergoing partial nephrectomy...

Cases in which an anomalous single coronary trunk arises from the ascending aorta are extremely rare. In percutaneous coronary intervention for the lesion of a coronary artery anomaly, several problems may occur, including selection of a guide catheter, insufficient backup force, and difficulties of stent delivery. The GuideLiner catheter, which is a coaxial guide extension having the advantage of rapid exchange, facilitates coronary intervention for complex lesions. We report a case of angina having a lesion in the left anterior descending artery of a single coronary trunk arising from the ascending aorta...

Due to the aging population undergoing percutaneous coronary intervention (PCI), interventional cardiologists are confronted daily with treatment of lesions with complex anatomy. Despite improvements in stent devices and PCI techniques, these lesions remain a challenge in terms of procedural success. Guide-extensions (GE) are coaxial "mother and child" catheters employed to facilitate device delivery but they can be used in many different complex scenarios. A comprehensive review of the possible applications of GE and of the GuideLiner™ (GL), the most widely used GE device, is missing...

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...

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...

Pulmonary artery catheters have been extensively used for hemodynamic assessment over the past several decades. We present a case that highlights the management of a known, but rare and catastrophic complication of pulmonary artery catheter based therapy. An elderly lady with acute decompensated heart failure, severe pulmonary hypertension, and atrial fibrillation on anticoagulation had a pulmonary artery catheter inserted for hemodynamic monitoring. Subsequently, the patient developed acute hemoptysis and damped pulmonary artery pressure waveforms during inflation of the catheter tip balloon...
