BACKGROUND: Ventriculo-atrial (VA) shunt is a routine technique for the treatment of hydrocephalus. Correct position at superior vena cava-right atrium junction is generally assessed by X-ray. We herein present the first experience of an alternative, non-radiographic technique to assess the distal end of the VA-shunts through an electrocardiographic (EKG) method. Such a technique is mutuated from the very large experience on central-venous catheters (CVC) worldwide: the EKG-guided method is a common and validated alternative to the standard radiological control of the location of the tip of any CVC...

REVIEW
Kathleen M Lamb, Hitoshi Hirose
Venoarterial extracorporeal membrane oxygenation is a rescue therapy in patients with severe cardiopulmonary failure. Often, cannulation is done emergently and the femoral vessels are most readily accessible for venous and arterial access. Unfortunately, complications with arterial femoral access can lead to devastating complications, primarily related to limb ischemia. A coordinated protocol of diligent limb examination by trained intensive care unit staff, near infrared spectroscopy monitoring of limbs, and placement of a distal perfusion catheter at the time of femoral cannulation or when signs of ischemia develop, can lead to successful limb salvage...

BACKGROUND: As neurointerventionalists aim to treat occlusions in the ever more distal vasculature, off-label catheters (OLCs) have been adapted for aspiration thrombectomy. This may not be without its attendant risks. Recently issued, a letter from the FDA cautioned providers against using OLCs as substitutes for FDA-cleared aspiration thrombectomy catheters, especially in the distal vasculature. In light of this, we evaluated the efficacy and safety of OLCs used for aspiration thrombectomy in the distal vasculature at our institution...

INTRODUCTION: Central venous catheter (CVC) access is commonplace in intensive care units. Patients undergoing computed tomographic angiography require injection of contrast at high flow rates (4.5 mL/s), often CVC access is not used due to safety concerns. The CVC might rupture at high flow rates, resulting in CVC fragmentation and embolization or contrast extravasation.The objective of this study is to determine the pressure required to burst a CVC under static load and compare this to the pressure generated by injection of contrast at high flow rates (dynamic load) through the distal (16-g) lumen of a triple-lumen CVC...

The endovascular realm has steadily increased its footing in the treatment of the aorta and all of its territories since the foundational case in 1990 by Parodi. The aortic arch, however, continues to be one of the last bastions for treatment via open surgery, which remains the gold standard. Significant comorbidity and prior cardiac surgery prevent open surgery from being the only preferred option, allowing novel endovascular procedures to be considered. Since 1999, more advanced endovascular systems have been created by companies such as Cook Medical, Bolton Medical, Medtronic, Endospan, Gore Medical, and, recently, Kawasumi...

Introduction In traditional locations, the standard Blalock-Taussig shunt presents numerous technical difficulties for percutaneous intervention. We changed our strategy to a central type shunt (Laks-type) with end-to-side pulmonary and side-to-side aortic anastomosis. The aim of this study was to determine whether this modified strategy would allow easier percutaneous manipulation in patients with small pulmonary arteries. Methods All children with a stretchable central vascular graft who required any form of percutaneous intervention were prospectively enrolled in the study...

A 45-year old male with no prior cardiac history, presented with cardiogenic shock in the setting of an anterolateral ST elevation myocardial infarction. We first placed a 2.5 Impella for hemodynamic support, and proceeded with emergent percutaneous coronary intervention to the proximal LAD. Several hours following percutaneous coronary intervention (PCI), the patient became acutely hypotensive and an echocardiogram revealed the Impella catheter was kinked within the left ventricle. The patient was taken back to the cath lab for Impella adjustment; however, damage to the distal catheter required the Impella be exchanged...
