The extension support guiding catheter has been used to perform complex percutaneous coronary intervention to increase back-up support for the guiding catheter or to ensure deep intubation for device delivery. However, because of its monorail design, advancement of the stent into the distal extension tubing segment is sometimes problematic. Although this problem is considered due to simple collision of the stent, operators have observed tangling between a monorail extension catheter and coronary guidewire in some patients...

Background: The incidence of healthcare-associated infections (HAIs) in the public health sector in South Africa is not known due to the lack of a surveillance system. We report on the challenges experienced in the implementation of a surveillance system for HAIs in intensive care units (ICUs). Methods: A passive, paper-based surveillance system was piloted in eight ICUs to measure the incidence of ventilator-associated pneumonia, catheter-associated urinary tract infection, and central line-associated bloodstream infection...

George Kassimis, Tushar Raina
Percutaneous coronary intervention (PCI) for the treatment of right coronary artery (RCA) ostial in-stent restenosis (ISR) can be challenging. The technical difficulties are compounded by excessive stent protrusion into the aorta, preventing coaxial engagement of the guiding catheter and wiring through the central stent lumen. Through this review, we aim to highlight the practical challenges encountered during the treatment of ostial RCA ISR through PCI and evaluate the various interventional techniques that have been used...

performing percutaneous coronary intervention (PCI) following transcatheter aortic valve implantation (TAVI) will become more frequent with the increasing use of TAVI in lower surgical risk populations. The ideal management strategy for coronary artery disease (CAD) in the setting of TAVI is not well defined and CAD is often left untreated prior to TAVI. Engaging the coronary ostia through the TAVI side cells can be challenging; techniques for rapid coronary cannulation, especially in the acute setting, need to be developed...

BACKGROUND: Atrioventricular (AV) nodal injury which results in cardiac conduction disorders is one of the potential complications of heart valve surgeries and radiofrequency catheter ablations. Understanding the topography of the AV conduction system in relation to the tricuspid and mitral valves will help in reducing these complications. METHODS: A tissue block of 3cmx4cm, which contain the AV node, bundle of His and the AV nodal extensions, was excised at the AV septal junction in 20 apparently normal human hearts...

PURPOSE: The in situ fenestration of a standard endograft is currently limited by difficulties in targeting the fenestration site under fluoroscopic control and by the lack of a safe method to perforate the graft. Evidence in the literature suggests the use of a 3 D electromagnetic navigator to accurately guide the endovascular instruments to the target and a laser to selectively perforate the graft. The aim of this work is to provide design guidelines to develop a sensorized catheter to guide the laser tool to the fenestration site and conduct preliminary testing of the feasibility of the proposed solution...

A 15-year-old boy with neurofibromatosis type 1 (NF1) was referred to us for central venous catheter insertion, and on ultrasound of the neck, he was found to have extensive involvement of the brachial plexus due to the nerve sheath tumour. Multiple hypoechogenic lesions resembling the internal jugular vein and internal carotid artery were visualised and could be differentiated from the vessels by Doppler ultrasound. The importance of analyzing sonographic images of nerve sheath tumours, which can mimic blood vessels, and the importance of Doppler ultrasound for guiding central venous catheters in such patients to avoid nerve injury are discussed in this case report...

Common femoral vein occlusion (CFVO) is frequently found in patients with chronic venous insufficiency. The iatrogenic form, secondary to either central catheter or surgery, is very rare but highly symptomatic. Classical compression therapy barely improves the clinical status of these patients, making them suitable candidates for an interventional procedure for venous recanalization. METHODS: We report here three consecutive cases of iatrogenic CFVO referred to our outpatient clinic because the disease had an impact on daily life activities...

BACKGROUND: In endovascular embolization of intracranial aneurysms, a tortuous cervical internal carotid artery can limit guiding catheter access to a sufficiently high position. Although intermediate distal access catheters can go beyond the tortuous segment of internal carotid arteries, they may increase the risk of procedure-related complications, require significantly complex technical procedures, and limit the use of adjunctive techniques. Using simple neck extension alone, we successfully improved guiding catheter access in 2 patients...

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...
