INTRODUCTION AND PURPOSE: The increasing number of patients undergoing hemodialysis and the limited number of access sites have resulted in an increasing number of techniques to maintain vascular access for hemodialysis. Thrombosed arteriovenous (AV) fistulas with large venous aneurysms have poor treatment results, with both endovascular and surgical techniques, leading to a high rate of definitive AV access loss. The purpose of this study was to review the feasibility and initial results of this novel endovascular treatment of thrombosed AV fistulas with large venous aneurysms...

INTRODUCTION: The peripherally inserted central catheters (PICCs) are vascular access devices (VAD) that are increasingly being used in the pediatric population. If a small vein caliber prevents positioning the catheter in the arm, the following step is to position the same catheter in the supraclavicular area, which can be defined as an off-label use or "atypical" approach, first described by Pittiruti. MATERIALS AND METHODS: We retrospectively reviewed PICC positioning with puncture-site in the supra-clavicular area ("atypical" PICC insertion) and then tunneled on the chest...

Ulnar arterial access for cardiac catheterization and intervention is an alternative approach compared with radial or femoral access. Ulnar access is infrequently performed since the radial artery is readily palpable and is commonly used worldwide to minimize vascular complications from femoral access. Nevertheless, ulnar access provides a suitable access site in patients who are poor candidates for femoral access, have pre-existing radial occlusion, radial artery hypoplasia or hyperplasia from prior radial artery procedures, radial stenosis, radial loops, radial tortuosity, small radial arteries, and/or have future need for radial graft for dialysis or coronary artery bypass graft...

BACKGROUND: Peripherally inserted central catheters (PICCs) represent a mainstay of intravascular access in the neonatal intensive care setting when long-term vascular access is needed. Ideally, PICCs should be inserted and maintained in a central position with the tip ending in the superior or inferior vena cava. This is not always achievable, and sometimes the tip remains in a peripheral location. Higher complication rates have been reported with non-central PICCs; however these findings have not been confirmed in a solely neonatal series and PICCs with tips in peripheral veins have not been studied...

The arteriovenous graft (AVG) is one of the major types of permanent vascular access used to provide hemodialysis. Complications encountered with AVG use include stenosis, infection, thrombosis, and pseudoaneurysm formation. Venous outflow stenosis along with frequent needle cannulation at the same site can lead to breakdown of the graft material, resulting in pseudoaneurysm formation. In the following case, we illustrate common management principles used to treat pseudoaneurysms. While stent-grafts have been utilized for pseudoaneurysm repair, stent-graft usage is not always optimal...

Radial access for primary percutaneous coronary intervention (pPCI) in patients with ST-elevation acute myocardial infarction (STEMI) is recommended in high-volume experienced centers. This study investigated whether radial access for pPCI is safe even in a low-volume center. We performed radial access for pPCI in 171 patients. Major adverse cardiac events (total death, myocardial infarction, stroke) rate was 1.2%. The overall incidence of bleeding complications was 2.4%; there was no vascular complication at the access site...

In pigs, the deep location of the common carotid artery and overlying sternomastoideus muscle in the neck has led to the recommendation for a surgical cutdown for common carotid access, as opposed to minimally invasive techniques for vascular access. We sought to determine if direct percutaneous common carotid artery access in piglets is attainable. Seventeen piglets were anesthetized and intubated. Under two-dimensional and color flow Doppler ultrasound guidance, a 21 gauge needle was utilized to access the right common carotid artery...

INTRODUCTION: In the 50 years since the first pancreas transplant performed at the University of Minnesota, the surgical techniques employed have undergone many modifications. Techniques such as retroperitoneal graft placement have further improved the ability to reproduce the physiology of the «native» pancreas. We herein present our experience of a modified technique for pancreatic transplant, with the organ placed into a fully retroperitoneal position with systemic venous and enteric drainage of the graft by duodeno-duodenostomy...

INTRODUCTION AND OBJECTIVES: Paravalvular leak (PVL) is a possible complication after prosthetic valve implantation. PVL can cause significant symptoms of congestive heart failure and/or hemolysis. Medical therapy is palliative and reoperation has a high mortality rate. Percutaneous transcatheter closure is a promising alternative for symptomatic patients at high surgical risk. We aim to review the efficacy and safety of percutaneous PVL closure in a consecutive series of patients referred to our center...

INTRODUCTION: Vascular closure devices (VCDs) are commonly used to achieve hemostasis of arterial access sites, but there is little comparative data on the variety of VCDs currently in clinical use. We reviewed the VCD experience at our institution to determine the safest and most effective VCD. MATERIALS AND METHODS: Retrospective analysis of 907 consecutive arterial procedures in interventional radiology from June 2012 to June 2014 was performed. Five VCDs were used: Angio-Seal (n = 478), FISH (n = 56), Mynx (n = 56), Perclose (n = 61), and Starclose (n = 68)...

BACKGROUND: Warfarin discontinuation with heparin bridging is a common practice in patients receiving warfarin prior to elective coronary angiography (CAG). The uninterrupted warfarin strategy has been suggested to be alternative option for patients with high thromboembolic risk. Therefore, we aimed to assess the safety of elective transfemoral CAG during uninterrupted warfarin therapy compared to heparin bridging. METHODS: This study was a randomized open-label design with blinded event evaluation...

Arteriotomy closure devices (ACDs) are routinely used for vascular closure during invasive cardiovascular procedures. They decrease time to hemostasis as well as length of stay. Major complications such as arterial ischemia and occlusion can be encountered in a minority of patients. We are describing a series of 3 patients with access site closure using Angio-Seal after coronary angiography who developed intermittent claudication within 2-3 weeks of follow-up. Access site thrombosis/stenosis in the CFA was found in all the three cases...

BACKGROUND: Peripheral Intravenous cannula (IV) is the most common vascular access device used to administer medications with the exception of medication or fluid with high or low PH or hyperosmolarity which may cause severe damage to small veins. The insertion of a peripheral intravenous cannula in newborn infants can be difficult. Appropriate veins with sufficient capacity to insert a cannula become less available throughout the hospital stay. Once a peripheral intravenous cannula is inserted, it is desirable that its patency can be maintained as long as possible...
