A refined percutaneous rhizotomy with DSA-guided ethanol for the second-line treatment of trigeminal neuralgia.

Background: Percutaneous rhizotomy is a group of techniques used to treat trigeminal neuralgia. Radiofrequency thermocoagulation (RF) and Chemical Rhizotomy (CR) using glycerol are among the most frequently used methods. We have recently refined Ethanol Rhizotomy (ER) under Digital Subtraction Angiography (DSA) guidance.

Safety and Efficacy of Liver Venous Deprivation Following Transarterial Chemoembolization Before Major Hepatectomy for Hepatocellular Carcinoma.

Objective: This study aimed to evaluate the safety and efficacy of liver venous deprivation (LVD) following transarterial chemoembolization (TACE) in patients with hepatocellular carcinoma (HCC).

Methods: Between January 2021 and December 2022, HCC patients indicated for hepatectomy with initial insufficient future liver remnant (FLR) underwent LVD after TACE to induce preoperative liver hypertrophy.

Results: Twenty-seven HCC patients with a median age of 55 years underwent LVD.

Multiple primary squamous cell carcinomas of the oral cavity: A cross-sectional study in vietnam.

Background: Multiple primary squamous cell carcinomas (MPSCs) of the oral cavity are very uncommon in clinical practice. This study describes the clinical features, imaging, and treatment characteristics of the oral cavity with MPSCs at the same time of diagnosis in our center. Besides, we review the literature and prior studies on MPSCs.

The impact of trans-arterial embolization on the result of chemoradiotherapy in oral cavity cancer.

Evaluation of the hemostatic effect of trans-arterial embolization on patients with advanced oral cavity cancer who had bleeding complications while undergoing definitive concurrent chemoradiotherapy (CCRT). Additionally, assess the effect of trans-arterial embolization on treatment response following concurrent chemoradiotherapy, as well as overall survival (OS) and progression-free survival (PFS) in the group of patients following the intervention. From September 2018-June 2021, a retrospective descriptive study was conducted on 16 patients with inoperable, locally advanced oral cavity cancer who received definitive concurrent chemoradiotherapy, experienced acute bleeding complications, and received selective intravascular intervention with various embolization materials at Vietnam National Cancer Hospital.

Hypovascular pancreatic neuroendocrine tumor with hepatic metastases: A case report and literature review.

Hypovascular pancreatic neuroendocrine tumors are uncommon pancreatic tumors and commonly misdiagnosed as pancreatic ductal adenocarcinoma or chronic mass-forming pancreatitis. The liver is the organ most commonly affected by neuroendocrine tumor metastases but hepatic neuroendocrine tumor metastases are quite difficult to discriminate from other hepatic metastases and primary hepatic tumors. We describe a case of a 47-year-old man with incidentally detected multiple hepatic lesions on ultrasound.

Non-functioning adrenocortical carcinoma.

Adrenocortical carcinoma (ACC) is a rare malignancy that arises from the adrenal cortex and can be classified as either non-functioning or functioning. A patient with non-functioning ACC may present no specific symptoms. Imaging analysis can provide some information to a clinician who suspects ACC, such as tumor size, density, washout, necrosis, hemorrhage, and calcification.

The Role of Shear Wave Elastography in the Discrimination Between Malignant and Benign Thyroid Nodules.

Background: Grayscale ultrasound (US) is the most common imaging modality for the assessment of thyroid nodules.

Objective: This research aimed to assess the value of using the elasticity index (EI), obtained using shear wave elastography (SWE), to discriminate between malignant and benign thyroid nodules.

Materials And Methods: A total of 86 patients (94 distinct thyroid nodules) were operated on at Vietnam National Cancer Hospital from June 2018 to June 2019.

The Value of CT and MRI for Determining Thymoma in Patients With Myasthenia Gravis.

The aim of the study was to evaluate the usefulness of computed tomography (CT) and magnetic resonance imaging (MRI) for differentiating thymoma from nonthymoma abnormalities in patients with myasthenia gravis (MG). A cross-sectional study of 53 patients with MG, who had undergone surgical thymectomy, was conducted at 103 Hospital (Hanoi, Vietnam) and Cho Ray Hospital (Ho Chi Minh City, Vietnam) during August 2014 and January 2017. The CT and MRI images of patients with MG were qualitatively and quantitatively (radiodensity and chemical shift ratio [CSR]) analyzed to determine and compare their ability to distinguish thymoma from nonthymoma abnormalities.
