Background: Surgical resection remains the treatment of choice for primary, secondary liver cancer and a number of benign liver lesions. Complications are mainly related to blood loss. Radiofrequency-assisted liver resection (RF-LR) has been proposed in order to achieve minimal blood loss during parenchymal transection.
Patients And Methods: Between May 2005 and April 2007, 46 consecutive patients with various hepatic lesions underwent RF-LR using Radionics, Cool-Tip System. There were 28 men and 18 women with median age 65 years (range 54-76 years). Twelve major and 34 minor hepatectomies were performed for various diseases: hepatocellular carcinoma (n=19), metastatic carcinoma (n=23), focal nodal hyperplasia (n=2) and intrahepatic cholangiocarcinoma (ICC) (n=2). Hepatic inflow occlusion was not used.
Results: No perioperative death was documented. Median blood loss was 100ml (range 30-300cm(3)). Blood transfusion was required postoperatively in one patient. Median transection time was 35min (15-60min). Three patients developed biliary fistulas, four patients pleural effusions, one patient hyperbilirubinemia, two pneumonia and four wound infection. The median postoperative hospital stay was 6 days (range 4-10 days). In a median 12 month follow-up (range 3-24 months), four patients with colorectal metastases (CRM) and one patient with ICC developed recurrence.
Conclusions: Cool-Tip RF device provides a unique, simple and safe method of bloodless liver resections and is indicated in cirrhotic patients with challenging hepatectomies (segment VIII, central resections).

Endothelial-specific knockout of the scramblase TMEM16F impairs in vivo clot formation.

Objective: Loss of function of the phospholipid scramblase (PLS) TMEM16F results in Scott Syndrome, a hereditary bleeding disorder generally attributed to intrinsic platelet dysfunction. The role of TMEM16F in endothelial cells, however, is not well understood. We sought to test the hypothesis that endothelial TMEM16F contributes to hemostasis by measuring bleeding time and venous clotting in endothelial-specific knockout (ECKO) mice.

Background: Computed tomography angiography of the head (CTAH) is not routinely obtained during the initial evaluation of patients with traumatic intracranial hemorrhage (ICH); however, it is useful for diagnosing vascular pathologies that may have led to the bleed. The aims of this study were to identify traumatic ICH patient characteristics on presentation that are associated with positive CTAH findings to elucidate which ones should prompt a CTAH and compare outcomes of patients with positive and negative CTAH findings.
Methods: This is a retrospective cohort study of 522 patients who had blunt traumatic ICH and subsequently received CTAH between January 1, 2017, and January 1, 2022.
Higher Risk Renal Angiomyolipomas: Surveillance Remains a Safe Management Option.

Urology Service, Department of Surgery, Memorial Sloan Kettering Cancer Center, New York, New York.
Purpose: This retrospective study furthers our understanding of risk factors associated with hemorrhage and intervention in renal angiomyolipomas (R-AMLs), particularly in larger tumors (≥ 4 cm) and in childbearing-age (CBA; younger than 50 years) women. The objective was to refine risk stratification and optimize patient management.
Methods: Review of our institutional database identified patients with radiographic R-AML from 1997 to 2023.

Thalamic hemorrhage is a type of intracerebral hemorrhage with high disability and mortality rates. Because of its deep bleeding location, irregular shape of the hematoma, and compression of the third ventricle, it is not suitable for craniotomy. This paper reports a case of a 63-year-old male patient who sought medical attention for left-sided basal ganglia and thalamus hemorrhage that broke into the ventricles.

Importance: The net clinical effect of early vs later direct oral anticoagulant (DOAC) initiation after atrial fibrillation-associated ischemic stroke is unclear.
Objective: To investigate whether early DOAC treatment is associated with a net clinical benefit (NCB).
Design, Setting, And Participants: This was a post hoc analysis of the Early Versus Late Initiation of Direct Oral Anticoagulants in Post-Ischaemic Stroke Patients With Atrial Fibrillation (ELAN) open-label randomized clinical trial conducted across 103 sites in 15 countries in Europe, the Middle East, and Asia between November 6, 2017, and September 12, 2022, with a 90-day follow-up.
