AUF: arterioureteral fistula; CIA: common iliac artery; DJ: double J; EIA: external iliac artery; IIA: internal iliac artery; NBCA: N-butyl cyanoacrylate; PCN: percutaneous nephrostomy.

PURPOSE This study aimed to evaluate the technical success rate, complications, and radiation doses of ultrasound- and fluoroscopy-guided percutaneous nephrostomy (PCN) in patients with a nondi- lated renal collecting system. METHODS Over a 10-year period, 50 patients were referred for PCN of 60 kidneys with a nondilated renal collecting system. The patients included 22 males and 28 females with a mean age of 63.2 years (range: 35-87 years). The most common reason for PCN in these patients was p

Background/Aims: We studied the impact of socioeconomic status (SES) on mortality in hepatocellular carcinoma patients and analyzed the effect of SES on initial treatment allocation. Methods: A cohort study was conducted using data from the National Health Insurance Service- National Sample Cohort of Korea. A total of 3,032 hepatocellular carcinoma patients who were newly diagnosed between January 2003 and December 2013 were included. Income level was categorized as Medical Aid and ≤30th, 31st-7

Background The inferior phrenic artery (IPA) is the most common extrahepatic feeder for hepatocellular carcinoma (HCC) during transhepatic arterial chemoembolization (TACE). Purpose To compare the incidence of diaphragmatic weakness in patients with HCC after TACE of the right IPA conducted using either N-butyl cyanoacrylate (NBCA) or gelatin sponge particles. Material and Methods Medical records of 111 patients who underwent TACE of the right IPA using NBCA were retrospectively reviewed and com

PURPOSE: To evaluate if the mechanical injection of saline is effective in restoring patency of a totally implantable venous access port (TIVAP) with an intraluminal occlusion. MATERIALS AND METHODS: From January 2017 to June 2019, 64 cases of dysfunction of a TIVAP were referred to interventional radiology. Among these, 16 cases showed normal function of the TIVAP, 19 cases the showed the appearance of a fibroblastic sheath, and 29 cases showed intraluminal occlusion. Mechanical recanalization

STUDY QUESTION: What are the maternal and neonatal outcomes of second delivery in women who underwent uterine artery embolization (UAE) during their first delivery? SUMMARY ANSWER: Women who underwent UAE during their first delivery exhibited higher risks of placental problems, preterm births, and postpartum hemorrhage (PPH) in second delivery and the second offspring also showed increased risk of major congenital malformations, admission to the neonatal intensive care units (NICU), necrotizing

BACKGROUND: The optimal antiplatelet regimen after standard endovascular aneurysm repair (EVAR) in patients without atherosclerotic cardiovascular disease remains uncertain. Clinical guidelines offer limited recommendations, and data specific to this population are sparse. This study aimed to compare the efficacy and safety of single versus dual antiplatelet therapy (DAPT) in patients undergoing standard EVAR for abdominal aortic aneurysms without established atherosclerotic cardiovascular disea

Purpose: To assess the safety and feasibility of intentionally positioning the catheter tip in the right atrium (RA) without an abutment during implantation of a totally implantable venous access port (TIVAP). Materials and Methods: We enrolled 330 patients who had undergone TIVAP implantation between January and December 2016 and postoperative chest CT. The TIVAP was placed using the single-incision technique to access the axillary vein directly from the incision line. To position the catheter

The purpose of this study is to investigate strategies for peripherally inserted central catheter (PICC) placement in patients with venous steno-occlusive lesion (VSOL). We performed a retrospective cohort study in adults with central or peripheral VSOL who underwent PICC placement procedures from January 2015 to December 2018. Four different strategies [selecting alternative pathway/over the wire (SAP/OTW), percutaneous transluminal angioplasty (PTA), re-puncture in ipsilateral arm (RIA), and c

: Noncompaction of ventricular myocardium, once thought to represent a rare cardiomyopathy, is being diagnosed with increased frequency. It is often accompanied by various congenital heart diseases. Coexisting valvular anomalies are an emerging issue that requires further investigation in patients with noncompaction cardiomyopathy, because they can increase the potential for adverse clinical events. This article describes the case of a 45-year-old male diagnosed with left ventricular noncompacti

Duodenal variceal bleeding is a rare but potentially life-threatening complication of portal hypertension, frequently associated with abnormal portosystemic collateral pathways. We present a case of successful plug-assisted retrograde transvenous obliteration (PARTO) performed for duodenal varices draining into the right gonadal vein via a mesocaval shunt in a patient with hepatocellular carcinoma and liver cirrhosis. Despite severe angulation and tortuosity of the shunt, a strategic approach in
