Objective: To evaluate the safety and efficacy of ethylene vinyl alcohol (EVOH) copolymer for the treatment of a variety of peripheral vascular pathologies. Results: Between October 2010 and October 2017, 43 patients who underwent total 54 EVOH embolization procedures for the treatment of peripheral vascular pathologies were included. The cases...

Creative, visionary, problem-solving “pioneers” in medicine established what we call today “minimally invasive procedures.” This chapter is but a brief summary of the highlights of the history of vascular and nonvascular interventional procedures. The chapter is by no means comprehensive, but an attempt has been made to emphasize some of the key ev...

Management of the high-risk obstetric patient is multidisciplinary. Interventional radiologists are an important part of that team, utilizing catheter-based techniques such as embolotherapy, etc. At times such therapies can be lifesaving, especially in the clinical setting of massive postpartum hemorrhage. This chapter provides an overview of these...

Transcatheter embolotherapy of the spermatic vein in males is a minimally invasive therapeutic option in the management of the male varicocele. Indications for treatment include pain, infertility/subfertility, and the presence of a varicocele in a male child or adolescent with testicular atrophy on the side of the varicocele. This chapter presents...

We examined the barriers and perceptions of using a 1-step daily disinfectant and ultraviolet light for environmental cleaning using an anonymous Likert scale survey. Results indicated that environmental services workers believe that cleaning is important for infection prevention and that ultraviolet light and 1-step daily disinfectant cleaner are...

Purpose: The aim of this project was to construct a low-cost customizable simulation system of aneurysms in the circle of Willis and its branches. Materials and Methods: DICOM images from an MRA head were used to create a Stereolithography model of the circle of Willis using Materialise InPrint. A desktop 3-D printer utilizing fused deposition mode...

Purpose: The purpose of this study was to monitor tumour blood flow with power Doppler ultrasound following antiangiogenic therapy with bevacizumab in order to optimally time the application of radiofrequency (RF) ablation to increase ablation diameter. Materials and methods: Athymic nude mice bearing human hepatocellular carcinoma xenografts we...

This study was undertaken to investigate the effect of paclitaxel and bevacizumab on the therapeutic efficacy of (90)Y-labeled B3 monoclonal antibody, directed against Le(y) antigen, for the treatment of Le(y)-positive A431 tumors implanted subcutaneously in the right hind flank of nude mice. When the tumor size reached ~200 mm(3), the mice receive...

Drug dose painting”: Heat-deployed liposomal doxorubicin during image-guided tumor ablation with radiofrequency or high-intensity focused ultrasound

When studying the binding of ligands to macromolecules immobilized at a surface, the question arises whether the surface binding sites are heterogeneous, as one might expect considering many factors such as intrinsic surface roughness, nonuniform density distribution of polymeric linkers and nonuniform chemical attachment producing different protei...

Once a homogeneous ensemble of a protein ligand is taken from solution and immobilized to a surface, for many reasons the resulting ensemble of surface binding sites to soluble analytes may be heterogeneous. For example, this can be due to the intrinsic surface roughness causing variations in the local microenvironment, nonuniform density distribut...

The objective was to create an inexpensive, portable, and accurate absorptive radiation force balance to measure acoustic powers of up to 100 watts generated by the high intensity focused ultrasound (HIFU) transducer. This paper describes the process of making an effective absorbing target with commercially available ingredients. Four different abs...

This paper describes a technique to improve the locomotion of a miniature crawling robot, (Heart Lander) that uses suction to adhere to the surface of the beating heart. During locomotion, maintaining a vacuum seal with at least one of the suction pads is crucial. A new algorithm was developed to analyze data from pressure sensors monitoring the su...

PURPOSE/AIM Medical schools are continuously struggling with ballooning IT budgets while trying to offer students access to computer based learning. Inexpensive DICOM viewers and anonymous HIPAA compliant radiology image data sets are widely available and provide low cost tools for first year medical student education in clinical anatomy and radiol...
