PURPOSE: Balloon guide catheters (BGCs) are used in endovascular treatment (EVT) for ischemic stroke. Previous literature did not distinguish between BGC use with and without inflated balloon. This study aims to compare outcomes between non-BCG and BGC use with and without inflated balloon during EVT. METHODS: Patients who underwent EVT for anterior circulation ischemic stroke between September 2020 and February 2023 were analyzed. Patients were divided into three groups: non-BGC, BGC with inflated balloon, or BGC without inflated balloon...

PURPOSE: This experimental study was designed to compare radial forces between the central portion and both ends of balloon catheters when dilating stenosis. MATERIALS AND METHODS: Three balloon catheters of 6 and 8 mm in diameter and of variable length were tested: Mustang, Conquest, and Genoss PTA. Cylindrical modules to position balloon catheters and install the measuring tip during radial force measurements were made using a 3D printer. The measuring tip created 20% stenosis at the inner lumen...

Tissue ablation techniques have long been used in clinical settings to treat various oncologic diseases. However, many of these techniques are invasive and can cause substantial adverse effects. Histotripsy is a noninvasive, nonionizing, nonthermal tissue ablation technique that has the potential to replace surgical interventions in various clinical settings. Histotripsy works by delivering high-intensity focused ultrasound waves to target tissue. These waves create cavitation bubbles within tissues that rapidly expand and collapse, thereby mechanically fractionating the tissue into acellular debris that is subsequently absorbed by the body's immune system...

AIMS AND OBJECTIVES:  To determine the predictive value of Emergency Surgery Score (ESS) with regard to mortality and morbidity rates of patients undergoing emergency laparotomy. METHOD: The ESS ranging from 0 to 29 is an extensive risk calculator based on 22 variables including important parameters like demographics, preoperative treatment, comorbidities, and laboratory values. Twenty patients who underwent emergency laparotomy were preoperatively assessed and ESS was calculated for each...

INTRODUCTION: High-flow priapism is rare, uncontrolled arterial inflow, preceded by penile or perineal trauma and arterial-lacunar fistula. There are several ways to treat high-flow priapism, i.e., conservative management, the use of ice packs, mechanical decompression, surgery, and super-selective arterial embolization. Embolization is currently widely accepted in patients who fail from conservative management. This study aimed to report the use of Gelfoam and microcoil embolization in recurrent high-flow priapism compared to PVA embolization...

OBJECTIVE: To assess the clinical impact of regular whole-body magnetic resonance imaging (WBMRI) surveillance in myxoid liposarcoma patients. METHODS: This was a retrospective cohort study of myxoid liposarcoma patients who underwent at least one WBMRI at our institution between October 2006 and December 2020. The effect of WBMRI on clinical management, namely treatment modification or additional diagnostic investigations was studied. A standardised WBMRI surveillance protocol was instituted in 2015...

NCRP Commentary No. 33 'Recommendations for Stratification of Equipment Use and Radiation Safety Training for Fluoroscopy' defines an evidence-based, radiation risk classification for fluoroscopically guided procedures (FGP), provides radiation-related recommendations for the types of fluoroscopes suitable for each class of procedure, and indicates the extent and content of training that ought to be provided to different categories of facility staff who might enter a room where fluoroscopy is or may be performed...

Videofluoroscopic swallowing study (VFSS), alongside flexible endoscopic evaluation of swallowing, represents the gold standard for diagnosing swallowing disorders and to determine severity, pathophysiology, and effective interventions, including texture modification. The clinical swallowing examination and assessment supplements these instrumental methods and serves as the basis for the modules of swallowing diagnostics. The adaptation of food and drink consistencies in dysphagia management has become widespread...

BACKGROUND: The indication of laparoscopic liver resection (LLR) for treating large hepatocellular carcinoma (HCC) is controversial. In this study, we compared the short-term and long-term outcomes of LLR and open liver resection (OLR) for large HCC. MATERIAL AND METHODS: We searched eligible articles about LLR versus OLR for large HCC in PubMed, Cochrane Library, and EMBASE and performed a meta-analysis. RESULTS: Eight publications involving 1,338 patients were included...

BACKGROUND: Hepatic artery infusion pump (HAIP) with floxuridine/dexamethasone and systemic chemotherapy is an established treatment regimen, which had been reported about converting 47% of patients with stage 4 colorectal liver metastasis from unresectable to resectable.1,2 To this effect, HAIP chemotherapy contributes to prolonged survival of many patients, which otherwise may not have other treatment options. Biliary sclerosis, however, is a known complication of the HAIP treatment, which occurs in approximately 5...

OBJECTIVE: Oral submucous fibrosis (OSF) is a chronic, insidious, progressive mucosal disease that may be affected by mutations in the Wnt/β-catenin signaling pathway. Panax notoginseng saponins (PNS) is a powerful anti-fibrosis agent; however, its effect and mechanism in treating OSF remain unclear. This study investigated the effect and mechanism of PNS treatment for OSF. STUDY DESIGN: Arecoline was used to induce OSF models in vivo and in vitro, which were then treated with PNS...

BACKGROUND: Limb-shaking transient ischemic attack (LSTIA) is a rare neurological condition which presents with involuntary jerky movements of the arm or leg, often because of carotid stenosis or occlusion. Due to the rarity of the condition, the epidemiology of LSTIA is poorly understood and the disease is frequently misdiagnosed. There is no standard treatment to date. The purpose of this study is to provide an overview of the epidemiology of LSTIA and its current treatment options...

Breast cryoablation is a minimally invasive image-guided percutaneous procedure to treat fibroadenomas and early-stage breast cancer utilizing liquid nitrogen or argon gas to create extremely cold temperatures that devitalize targeted tissue. Although more long term data are needed, this outpatient procedure is well tolerated and carries minimal risks, including non-target thermal injury that can be mitigated by careful planning and proper technique. Building a sustainable breast cryoablation service in a radiology practice poses several practical considerations, such as training proceduralists, purchasing equipment, recruiting patients, and understanding the revenue cycle...

BACKGROUND: Catheter-directed thrombolysis (CDT) for acute iliofemoral deep venous thrombosis (DVT) is an endovenous interventional therapy that can quickly remove the acute thrombus, thereby improving the clinical outcomes of proximal DVT. However, instrumentation of extensive fresh thrombus may be associated with iatrogenic pulmonary embolism (PE). Therefore, we aimed to compare CDT's safety, complications, and perioperative embolic (PE) insults for acute iliofemoral DVT, with and without an IVC filter...

METHODS: A retrospective observational study was conducted between 2014 and 2021 at a single institution...

PURPOSE: The treatment of cardiovascular diseases requires complex and challenging navigation of a guidewire and catheter. This often leads to lengthy interventions during which the patient and clinician are exposed to X-ray radiation. Deep reinforcement learning approaches have shown promise in learning this task and may be the key to automating catheter navigation during robotized interventions. Yet, existing training methods show limited capabilities at generalizing to unseen vascular anatomies, requiring to be retrained each time the geometry changes...
