Interventional endovascular treatments of dysfunctional arteriovenous (AV) access for hemodialysis can cause pain and discomfort to the patients. Ultrasound-guided brachial plexus block (BPB) is an alternative regional anesthesia method, but conventional BPB using ropivacaine or bupivacaine may long-lasting motor power loss, significantly reducing patient satisfaction. This study aimed introduce only 1% lidocaine, which induces sensory loss while minimizing block, evaluate efficacy safety...

To investigate the effectiveness of intraprocedural dual-phase cone-beam computed tomography (CBCT) in detecting hepatocellular carcinoma (HCC) during conventional transcatheter arterial chemoembolization (TACE) and its effect on improving treatment outcomes. Between November 2018 2019, data from 111 patients with unresectable HCCs (N = 263 lesions) were reviewed retrospectively. All had undergone baseline magnetic resonance imaging (MRI) scans within one month prior to procedure. Both...

In this report, we present a rare case of primary signet-ring cell carcinoma the appendix in 51-year-old woman with right lower quadrant pain. Since non-specific concentric appendiceal wall thickening was found radiologic evaluation, it misdiagnosed as non-tumorous appendicitis. An in-depth examination correlation between sonographic and histopathologic findings demonstrated that single markedly thickened hypoechoic layer well correlated diffuse infiltration tumor cells both submucosal...

Isolated left-sided portal hypertension is a rare clinical syndrome caused by splenic veno-occlusive disease. Splenic vein thrombosis and extrinsic compression causes proximal hypertension, the blood flows into superior mesenteric or through upper stomach's collateral vessels, such as short gastric, coronary, gastroepiploic veins. Open splenectomy recommended to treat gastrointestinal bleeding isolated hypertension. Interventional management could be clinically useful option for selected...

Supradiaphragmatic liver is a rare condition. Establishing an accurate preoperative diagnosis difficult. Operative exploration necessary to differentiate this lesion from intrathoracic masses, such as pleural based tumor, diaphragmatic tumor and peripheral lung tumor. However, with the aid of hepatocyte-specific magnetic resonance imaging contrast agent, gadoxetic acid (Gd-EOB-DTPA), functional hepatocytes in can be identified hepatobiliary phase, potentially allowing non-invasive diagnosis....

This study aimed to assess the effect of vessel size and flow characteristics on maturation autogenous radiocephalic arteriovenous fistulae (RCAVFs).We retrospectively reviewed records patients undergoing RCAVF creation at a single medical center from January 2013 December 2019. Operative variables were compared between whose matured those failed mature.Overall, 152 (33 whom women) with mean age 62.6±13.6 years underwent creation; functional was achieved in 123. No statistically significant...

This study aimed to validate the accuracy of peripherally inserted central catheter (PICC) length prediction formula using only anteroposterior chest radiographs (AP-CXR) and technical feasibility bedside ultrasound-guided PICC placement. included 156 Asian adult patients who underwent placement at three hospitals from September 2021 March 2022. The shortest straight-line distance cubital crease puncture point (CP) was measured first. Using a previous study, CP + estimated (eCL) calculated...

Cone-beam computed tomography (CBCT) has proven to be a safe and effective adjunctive imaging tool for interventional radiology. Nevertheless, limited studies have examined the application of CBCT in renal artery embolization (RAE). The objective this study is evaluate role intra-procedural decision-making RAE. This multicenter retrospective included 40 consecutive patients (age: 55.9 ± 16.5 years; male, 55%) who underwent during RAE from January 2019 2023. additional information provided by...

An iatrogenic graft-to-vein fistula is a rare complication with uncertain clinical significance that can occur due to repetitive needle injury traversing between vascular access graft and nearby vein.We present case of an arteriovenous (AVG) complicated by at the proximal cannulation zone thrombosed distal venous limb caused steno-occlusive lesion graft-vein (GV) anastomosis.Aspiration thrombectomy percutaneous transluminal angioplasty (PTA) was insufficient address high-flow...

Background and Objectives: The novel double-pigtail catheter (DPC) has an additional pigtail coiling at the mid-shaft with centripetal multiple side holes. aim of present study was to investigate advantages efficacy DPC in overcoming complications conventional single-pigtail catheters (SPC) used drain pleural effusion. Materials Methods: Between July 2018 December 2019, 382 effusion drainage procedures were reviewed retrospectively (DPC, n = 156; SPC without holes, 110; holes [SPC+M], 116)....

Transcatheter arterial embolization (TAE) is not common for hemorrhagic complications after gynecologic hysterectomy.To evaluate the effectiveness and safety of TAE hemorrhage hysterectomy diseases.This a retrospective, multicenter study, which investigated 11 patients (median age = 45 years) who underwent between 2004 2020.The median interval surgery angiography was one day (range 0-82 days). Hemodynamic instability massive transfusion were present in 6 (54.5%) 4 (36.4%) patients,...

Acute puerperal uterine inversion is a rare postpartum obstetric complication; however, without rapid diagnosis and appropriate management, it life-threatening. Substantial bleeding hinders the verification of partially inverted uterus, possibly delaying treatment. Herein, we present report 32-year-old female presenting with massive managed by artery embolization. The peculiar course bowing inferiorly along fundus during embolization could uncover inversion, which was not diagnosed physical...

Epipericardial fat necrosis (EPFN) is a relatively rare cause of acute chest pain, with only five pediatric cases having been reported in the English-language medical literature to date. EPFN can be diagnosed based on clinical symptoms pleuritic pain and classic CT features typically ovoid fatty lesions surrounded by rim or capsule mediastinal pericardial areas. Previous studies have that contrast-enhanced MRI detect typical signal changes adults EPFN. We report case using...

Abstract The aim of the current study was to determine prevalence anatomic variant in cephalic arch on preoperative mapping venography and evaluate patency rates predictors patients with brachiocephalic fistulas. retrospectively evaluated 1004 consecutive who underwent bilateral from July 2006 December 2018 a single center. overall 17.2% (173/1004). For analysis, 128 fistulas were divided into two groups: standard anatomy (SA) group ( n = 97) (VA) 31). There no significant differences...

The aim of this study was to evaluate the patency helical interwoven SUPERA stent for salvaging prosthetic arteriovenous (AV) grafts with rapidly recurrent thrombotic occlusion developed within a short time period after successful percutaneous transluminal angioplasty.
