Method: This retrospective study analyzed the medical records of consecutive patients who underwent Double-J stent placement with the TTW technique at Asan Medical Center and Gil Medical Center between January 2016 and February 2023. Patient histories, reasons for employing the TTW technique, TTW pathways, and complications were reviewed.

Thyroid Artery Embolization for Tracheostomy Site Bleeding: A Report of Three Cases.

In this case report, the authors present three cases of post-tracheostomy site bleeding successfully treated using embolization, supplemented by CT and angiography images. This report highlights that embolization can be a viable alternative when surgical or endoscopic interventions fail or are not applicable in cases of post-tracheostomy bleeding.

Endovascular Treatment of Iatrogenic Iliac Vein Rupture during Total Hip Arthroplasty: A Case Report.

We present a case of iatrogenic iliac vein rupture with venous thrombosis during total hip arthroplasty that was endovascularly treated with the insertion of covered and uncovered stents, aspiration, and balloon maceration of the thrombus. We describe in detail, with a schematic diagram, an endovascular treatment method that can be performed under local anesthesia alone and explain how to overcome the situation when the diameter of the covered stent is inadequate to cover the iliac vein.

Renal abscess in a Lionhead rabbit due to and : A case report.

Background: In rabbits, renal abscesses (pus-filled sores) are rare and diagnosis remains challenging. Therefore, in this study, we aimed to determine the clinical manifestation and diagnostic tests associated with renal abscess identification in rabbits.

Case Description: A four-and-a-half-year-old castrated male Lionhead rabbit with a history of poor appetite and abdominal distension was admitted to the animal hospital.

Radiologic Insertion of a Covered Esophageal Stent Using the Rendezvous Technique: A Case Report.

In this report, we present a case of a radiotherapy-induced tracheoesophageal fistula treated with the fluoroscopy-guided insertion of a covered stent through the gastrostomy route using both the antegrade and retrograde approaches. The initial antegrade endoscopic and fluoroscopic stent insertion procedure failed due to severe esophageal stricture. Compared to the endoscopic approaches, fluoroscopy-guided radiologic procedures are generally less invasive and more successful because they allow for a better understanding of the anatomy outside the lumen during the procedure and enable the use of devices with smaller diameters.

Multi-approach assessment of groundwater biogeochemistry: Implications for the site characterization of prospective spent nuclear fuel repository sites.

The disposal of spent nuclear fuel in deep subsurface repositories using multi-barrier systems is considered to be the most promising method for preventing radionuclide leakage. However, the stability of the barriers can be affected by the activities of diverse microbes in subsurface environments. Therefore, this study investigated groundwater geochemistry and microbial populations, activities, and community structures at three potential spent nuclear fuel repository construction sites.

Temperature-dependent microbial reactions by indigenous microbes in bentonite under Fe(III)- and sulfate-reducing conditions.

Bentonite is a promising buffer material for constructing spent nuclear fuel (SNF) repositories. However, indigenous microbes in bentonite can be introduced to the repository and subsequent sealing of the repository develops anoxic conditions over time which may stimulate fermentation and anaerobic respiration, possibly affecting bentonite structure and SNF repository stability. Moreover, the microbial activity in the bentonite can be impacted by the heat generated from radionuclides decay.

Use of antegrade wire guidance for retrograde transjugular/transfemoral venous access in the treatment of dysfunctional hemodialysis access: A retrospective analysis.

Background: Transvenous access for endovascular treatment of dysfunctional hemodialysis (HD) access can be technically difficult in the retrograde selection of the HD access. This study aims to evaluate the efficacy of primary antegrade wire guidance in assisting transvenous access.

Methods: A total of 41 transvenous access procedures (17 with and 24 without antegrade wire guidance), performed between March 2019 and February 2023, were included.

[Interventional Management for Pelvic Trauma].

Traumatic pelvic injuries usually include high-energy crush injuries and are associated with significant morbidity and mortality. Mortality rates range from 6% to 15% and increase to 36%-54% in cases of fractures that result in increased pelvic volume. Therefore, retroperitoneal hemorrhage can spiral and progress to hemorrhagic shock.

Endovascular treatment of traumatic iliac venous injury combined with phlegmasia cerulea dolens in Korea: a case report.

Traumatic iliac venous injury is rare but can be fatal. Although surgical management is considered a primary treatment method, urgent treatment is required when deep venous thrombosis and subsequent phlegmasia cerulea dolens is combined. It is difficult to treat by surgical management, and pharmaceutic thrombolysis cannot be applied due to the trauma history.

Percutaneous creation of new bilioenteric anastomosis in a patient with accidentally failed hepaticojejunostomy.

If the cause of the bile leakage after hepaticojejunostomy is accidental non-anastomosis of one bile duct, it is unlikely that the leakage will resolve spontaneously, and reoperation may be necessary. However, if the patient has contraindications to surgery, other treatments should be considered. In this case report, we describe a new percutaneous tract creation between the isolated right bile duct and Roux-en-Y afferent jejunal loop in a patient who underwent hepaticojejunostomy, and the right bile duct was accidentally not anastomosed with the jejunal loop.

Early Gait Function After Lung Transplantation in Patients With and Without Pretransplant Extracorporeal Membrane Oxygenation Support.

Objective: We aimed to investigate the recovery of gait function, muscle strength, and the achievement of an independent gait after lung transplantation (LT) in patients with and without pretransplant extracorporeal membrane oxygenation (ECMO) support.

Methods: We retrospectively reviewed the medical records of 33 inpatients who underwent bilateral LT and received physical therapy. We assessed the Functional Ambulatory Category (FAC) and Manual Muscle Test (MMT) scores at baseline, 1 month, and 3 months of rehabilitation and the time it took to achieve a FAC score of 3 within 3 months of LT surgery in ECMO and non-ECMO patients.

Advanced virtual monoenergetic imaging algorithm for lower extremity computed tomography angiography: effects on image quality, artifacts, and peripheral arterial disease evaluation.

Purpose: To investigate the image quality of lower extremity computed tomography angiography (LE-CTA) using a reconstruction algorithm for monoenergetic images (MEIs) to evaluate peripheral arterial disease (PAD) at different kiloelectron volt (keV) levels.

Methods: A total of 146 consecutive patients who underwent LE-CTA on a dual-energy scanner to obtain MEIs at 40, 50, 60, 70, and 80 keV were included. The overall image quality, segmental image quality of the arteries and PAD segments, venous contamination, and metal artifacts from prostheses, which may compromise quality, were analyzed.

Activity-Stability Trends of the Sb-SnO@RuO Heterostructure toward Acidic Water Oxidation.

Accomplishments of enhanced activity and durability are a major concern in the design of catalysts for acidic water oxidation. To date, most studied supported metal catalysts undergo fast degradation in strongly acidic and oxidative environments due to improper controlling of the interface stability caused by their lattice mismatches. Here, we evaluate the activity-stability trends of in situ crystallized antimony-doped tin oxide (Sb-SnO)@RuO (Sb-SnO@RuO) heterostructure nanosheets (NSs) for acidic water oxidation.

Estimating postsurgical outcomes of patients with a single hepatocellular carcinoma using gadoxetic acid-enhanced MRI: risk scoring system development and validation.

Objectives: To develop and validate risk scoring systems using gadoxetic acid-enhanced liver MRI features and clinical factors that predict recurrence-free survival (RFS) of a single hepatocellular carcinoma (HCC).

Methods: Consecutive 295 patients with treatment-naïve single HCC who underwent curative surgery were retrospectively enrolled from two centers. Cox proportional hazard models developed risk scoring systems whose discriminatory powers were validated using external data and compared to the Barcelona Clinic Liver Cancer (BCLC) or American Joint Committee on Cancer (AJCC) staging systems using Harrell's C-index.

Artificial intelligence-based iliofemoral deep venous thrombosis detection using a clinical approach.

Early diagnosis of deep venous thrombosis is essential for reducing complications, such as recurrent pulmonary embolism and venous thromboembolism. There are numerous studies on enhancing efficiency of computer-aided diagnosis, but clinical diagnostic approaches have never been considered. In this study, we evaluated the performance of an artificial intelligence (AI) algorithm in the detection of iliofemoral deep venous thrombosis on computed tomography angiography of the lower extremities to investigate the effectiveness of using the clinical approach during the feature extraction process of the AI algorithm.

Imaging Findings of Peripheral Arterial Disease on Lower-Extremity CT Angiography Using a Virtual Monoenergetic Imaging Algorithm.

Peripheral arterial disease (PAD) is common in elderly patients. Lower-extremity CT angiography (LE-CTA) can be useful for detecting PAD and planning its treatment. PAD can also be accurately evaluated on reconstructed monoenergetic images (MEIs) from low kiloelectron volt (keV) to high keV images using dual-energy CT.
