OBJECTIVE. The purpose of this article is to define the role of splenic embolization in trauma patients and in patients presenting for treatment of thrombocytopenia and portal hypertension. This article reviews the indications, technical considerations, outcomes, and complications of splenic artery embolization.
OBJECTIVE. In the United States, more than 250,000 patients with end-stage renal disease are dialyzed through arteriovenous fistulas (AVFs). The three most common AVFs are the radiocephalic fistula, the brachiocephalic fistula, and the brachial artery–to–transposed basilic vein fistula. Although many potential access site stenoses can and do occur within any given fistula, each fistula has a characteristic site of stenosis. This article will discuss the characteristic site of stenosis for each type of fistula including the effects of stenosis at that site on fistula function, and their treatment.
OBJECTIVE. The purpose of this article is to describe the indications for and approach to image-guided percutaneous ablation of renal tumors.
OBJECTIVE. The practice guideline of the American Association for the Study of Liver Diseases currently recommends transarterial chemoembolization (TACE) for the treatment of intermediate-stage hepatocellular carcinoma (HCC). The use of transarterial radioembolization (TARE) using 90Y microspheres is not formally recommended. This article discusses the current clinical applications of TACE and TARE and compares the clinical utility of these techniques for various subpopulations of patients with HCC.
OBJECTIVE. The purpose of this article is to review the roles of angiography, embolization, and various ancillary techniques in evaluating and managing gastrointestinal hemorrhage.
OBJECTIVE. This article reviews the development of transarterial chemoembolization (TACE) in Japan, particularly ethiodized oil–based conventional TACE, from historical, strategic, and technical points of view. We also present the current status of standardized conventional TACE.
OBJECTIVE. The objective of this study was to standardize our image acquisition protocol for CT-guided biopsy procedures.
OBJECTIVE. The purpose of this article is to review clinical applications and technologic development of MRI-guided percutaneous interventions performed in closed-bore MRI scanners.
OBJECTIVE. The purpose of this study was to evaluate the diagnostic yield and accuracy of CT-guided percutaneous biopsy of anterior mediastinal masses and assess prebiopsy characteristics that may help to select patients with the highest diagnostic yield.
OBJECTIVE. The purpose of this study was to evaluate the utility of radionuclide perfusion lung scanning in the evaluation of primary pulmonary vein stenosis (PVS) in pediatric patients by comparing it with angiography.
OBJECTIVE. The purpose of this study was to identify the prevalence of occult nodal metastases on routine ultrasound examination of internal mammary (IM) nodal basins in patients with breast cancer.
PURPOSE: Direct superficial femoral artery (SFA) antegrade puncture is a valid alternative to common femoral artery (CFA) access for peripheral vascular interventions. Data investigating vascular closure device (VCD) hemostasis of distant SFA 6F access are limited. We aimed to investigate the safety and effectiveness of the Starclose SE® VCD for hemostasis, following direct 6F antegrade SFA access distal to the femoral head.
PURPOSE: We aimed to evaluate patterns of local tumor progression (LTP) after radiofrequency ablation (RF ablation) of colorectal cancer liver metastases (CRCLM) and to highlight the percentage of LTP not attributable to lesion size or RF ablation procedure-related factors (heat sink or insufficient ablation margin).
PURPOSE: The classic symptoms and signs of carotid cavernous sinus fistula or cavernous sinus dural arteriovenous fistula (AVF) consist of eye redness, exophthalmos, and gaze abnormality. The angiography findings typically consist of arteriovenous shunt at cavernous sinus with ophthalmic venous drainage with or without cortical venous reflux. In rare circumstances, the shunts are localized outside the cavernous sinus, but mimic symptoms and radiography of the cavernous shunt. We would like to present the other locations of the arteriovenous shunt, which mimic the clinical presentation of carotid cavernous fistulae, and analyze venous drainages.
PURPOSE: We aimed to investigate the safety and functionality of tunneled transhepatic hemodialysis catheters in chronic hemodialysis patients.
