Occupational dose and associated factors during transarterial chemoembolization of hepatocellular carcinoma using real-time dosimetry: A simple way to reduce radiation exposure.

Transarterial chemoembolization is the standard treatment option for intermediate-stage hepatocellular carcinoma (HCC). However, during the interventional procedure, occupational radiation protection is compromised. The use of real-time radiation dosimetry could provide instantaneous radiation doses.

Endovascular Aneurysm Repair for Abdominal Aortic Aneurysm: A Comprehensive Review.

Abdominal aortic aneurysm (AAA) can be defined as an abnormal, progressive dilatation of the abdominal aorta, carrying a substantial risk for fatal aneurysmal rupture. Endovascular aneurysmal repair (EVAR) for AAA is a minimally invasive endovascular procedure that involves the placement of a bifurcated or tubular stent-graft over the AAA to exclude the aneurysm from arterial circulation. In contrast to open surgical repair, EVAR only requires a stab incision, shorter procedure time, and early recovery.

Change in Perfusion Angiography During Transcatheter Arterial Chemoembolization for Hepatocellular Carcinoma Predicts Short-Term Outcomes.

The purpose of this study is to quantitatively assess perfusion reductions occurring in hepatocellular carcinoma (HCC) during transcatheter arterial chemoembolization (TACE) using 2D perfusion angiography and to evaluate the relationships between various 2D perfusion angiography parameter changes and short-term tumor response. This prospective study included 172 patients (144 men and 28 women; mean [± SD] age, 65.4 ± 10.

Successful Transjugular Intrahepatic Portosystemic Shunt with Embolization Subsequent to Endoscopic Variceal Band Ligation for Bleeding Anorectal Varices.

Anorectal variceal bleeding is a rare occurrence; however, in such event, it could be fatal due to large size and high blood flow rate of varices. However, to date, there is no standardized treatment modality. Although endoscopic treatment can be provided, in cases of recurrent anorectal variceal bleeding, other therapeutic modalities for hemostasis are necessary.

Personalized acupuncture treatment with Sasang typology.

The Sasang typology, traditional Korean personalized medicine, divides people into four Sasang types and suggests type-specific medical herbs and acupuncture for more safe and effective treatment. The main idea of Sasang typology seems relatively simple; however, the Sasang type diagnosis and type-specific treatment in clinical situation has been difficult for the clinicians and researchers. This study provided clinical procedures of type-specific Tae-Geuk Acupuncture (TGA) therapy along with basic understandings on Sasang typology and clinical indices for Sasang type differentiation.

Inferior vena cava filter insertion through the popliteal vein: enabling the percutaneous endovenous intervention of deep vein thrombosis with a single venous access approach in a single session.

Purpose: We aimed to evaluate the efficiency of placing an inferior vena cava (IVC) filter through the same popliteal vein access site used for percutaneous endovenous intervention in patients with extensive lower extremity deep vein thrombosis.

Methods: This retrospective study included 21 patients who underwent IVC filter insertion through the popliteal vein over a three-year period. Patient medical records were reviewed for the location of the deep vein thrombosis, result of filter removal, and total number of endovascular procedures needed for filter insertion and recanalization of the lower extremity venous system.

Iliac Vein Stent Fracture Due to a Migrated Retrievable Vena Cava Filter.

We report a case of iliac vein stent fracture due to hooking by a migrated retrievable inferior vena cava filter in a 55-year-old woman with acute deep venous thrombosis related to May-Thurner syndrome.

Noninvasive biomarkers for acute hepatotoxicity induced by 1,3-dichloro-2-propanol: hyperpolarized 13C dynamic MR spectroscopy.

The purpose of this study was to investigate the cellular metabolite change for acute hepatotoxicity induced by 1,3-dichloro-2-propanol (1,3-DCP) in rats and its correlations with the enzyme levels.

Intra-Arterial Thrombolysis after Full-Dose Intravenous tPA via the "Drip and Ship" Approach in Patients with Acute Ischemic Stroke: Preliminary Report.

According to the "drip and ship" concept, patients who are not responsive to intravenous tissue plasminogen activator (IV-tPA) at a community hospital may be candidates for subsequent intra-arterial (IA) thrombolysis at a comprehensive stroke center. We elucidated the efficacy and safety of combined IV/IA thrombolysis via the drip and ship approach. We retrospectively reviewed patients with acute ischemic stroke who underwent combined IV/IA thrombolysis between March 2006 and June 2009.

Fracture of a Tempofilter II: an initial case report.

Tempofilter II is a device that is used for pulmonary embolism prophylaxis. Since the appearance of the Tempofilter II following withdrawal of the Tempofilter I, it has been reported that the Tempofilter II is safe, effective and useful. Here we report on the first case of a fracture of one leg of the filter and this leg was embedded in the inferior vena cava wall in a 62-year-old man with deep vein thrombosis.

Retrograde Tempofilter II™ placement within the superior vena cava in a patient with acute upper extremity deep venous thrombosis: the filter stands on its head.

The Tempofilter II is a widely used temporary vena cava filter. Its unique design, which includes a long tethering catheter with a subcutaneous anchor, facilitates the deployment and retrieval of the device. Despite this, the Tempofilter II has been used only in the inferior vena cava of patients with lower extremity deep venous thrombosis.
