Background and purpose Current large-bore catheters can be easily and safely placed in the intracranial vessels for the stabilization of microcatheters in several neurointervention scenarios. We considered that a novel 3.4 French catheter (TACTICS, Technorat Corporation, Aichi, Japan) might be useful for intermediate/distal access in a triaxial system. Here, we present our initial experience using the TACTICS catheter for treatment of intracranial aneurysms. Materials and methods A total of 35 endovascular coils were placed to embolize unruptured intracranial aneurysms of the anterior circulation using the TACTICS catheter between December 2016 and November 2017...

INTRODUCTION: Renal replacement therapy in end-stage kidney disease relies on dialysis in low-income countries. This maintenance treatment needs a reliable vascular access and is done through central venous catheter or creation of A-V fistulas. Several types of A-V fistulas can be done but due to some individual conditions, those possibilities may be exhausted rapidly. CASE PRESENTATION: A 31 year old female was diagnosed with an end stage renal disease for which she was prescribed maintenance dialysis...

BACKGROUND: Patients' intra and post procedural comfort, quick recovery, as well as procedure success, are key elements for choosing the right arterial access site. Radial artery access has been of increasing interest since it was first described. Advanced treatments of coronary lesions, from primary percutaneous interventions during ST elevation myocardial infarction cases to chronic total occlusion cases, have been increasingly done through the radial access. Distal left trans radial artery (dlTRA) is a new technique first described by Kiemineij...

Posterior cerebral artery (PCA) aneurysms can be technically challenging lesions due to the intricacy of perforating branches and the relationship to cranial nerves and the brainstem. Fusiform aneurysms of the perimesencephalic segment of the PCA are a rare finding which does not favor direct clip occlusion or reconstruction. In such cases, proximal parent vessel occlusion is an option for aneurysm treatment. Extracranial-intracranial (EC-IC) bypass can be used to revascularize beyond the lesion when considering proximal occlusion...

Coronary angiography and percutaneous coronary intervention using the radial approach are becoming more frequent. Pronounced guide catheter manipulation in cases with tortuous access routes may lead to severe catheter kinking or knotting. The purpose of this review article is to present several techniques to resolve radial access catheter knots and kinks. First, simple maneuvers such as gentle traction, rotation, and guidewire advancement can often resolve minor kinking; however, complex loops and kinks are often not reversible with these simple maneuvers...

PURPOSE: Central catheter placement is one of the most commonly performed procedures by pediatric surgeons. Here, we present a case series of patients where central access was obtained at our institution with the utilization of a novel ultrasound-guided technique. This series represents the first of its kind where the native, parent vessels were inaccessible, resulting in a challenging situation for providers. METHODS: A retrospective chart review was performed in pediatric patients (0-17 years) at a tertiary care institution between July 2012 and November 2017 on all central line procedures where ultrasound was utilized to cannulate the brachiocephalic or superior vena cava in face of proximal occlusion...

Percutaneous coronary intervention (PCI) of mammary artery bypass grafts through a trans-radial (TR) approach can present unique challenges, including coaxial vessel engagement of the guiding catheter, adequate visualization of the target lesion, sufficient backup support for equipment delivery, and the ability to reach very distal lesions. The GuideLiner catheter, a rapid exchange monorail mother-in-daughter system, facilitates successful interventions in such challenging anatomy. We present a case of a patient undergoing PCI of a right internal mammary artery (RIMA) graft via TR access in whom the graft could not be engaged with any guiding catheter...

Transcatheter aortic valve implantation was performed on a 78-year-old patient. Elective circulatory support with cardiopulmonary bypass was planned because of left ventricular function impairment and hemodynamic instability. Limited vascular access was due to a severe atherosclerotic aorta distal to the origin of the left carotid artery. The right arm was the only safe vascular access site. However, at least 2 vascular access sites for angiographic catheter and inflow of circulatory support were required. An arterial inflow line equipped with a side arm was developed to enable single access to the right axillary artery to be used for the above purposes...

Successful replantation of distal digital segments necessitates the establishment of sufficient outflow to minimize congestion and progressive tissue necrosis. In cases where only arterial anastomosis is feasible, an artificial outlet must be provided to maintain physiological requirements until microvenous circulation regenerates. This can be accomplished using any number of "exsanguination techniques" designed to facilitate egress through ongoing passive blood loss. Although reportedly effective, these measures are imprecise and carry a substantial risk of infection, scarring, and/or uncontrolled hemorrhage...
