Major vessel invasion, particularly involving the portal and superior mesenteric veins, poses significant challenges during the radical resection of hepatobiliary and pancreatic cancers. Oncovascular surgery is essential for curative outcomes, and often requires portomesenteric vein reconstruction. Techniques, such as lateral venorrhaphy, patch repair, end-to-end anastomosis, and interposition grafting, have been employed.

A 25-year-old female presented with a congenital painless growing mass on the right side of her neck with symptoms of tinnitus and difficulty breathing. Imaging revealed an aneurysm of the internal jugular vein reaching a maximum diameter of 9.2 cm, shifting the trachea and right thyroid lobe to the left side.

Article Synopsis
- The aim of the study was to create a reproducible animal model of tricuspid regurgitation (TR) using a self-expanding nickel-titanium stent.
- The experiment involved 10 pigs, 7 in the experimental group undergoing TR induction through stent implantation, while 3 served as controls without the stent.
- Results showed significant changes in cardiac structure and function in the experimental group, indicating successful model establishment with no fatalities, making this approach effective for further research on right ventricular issues.
New evidence for baroreflex and respiratory chemoreflex mediated cerebral sympathetic activation in humans.

The brain is highly innervated by sympathetic nerve fibres; however, their physiological purpose is poorly understood. We hypothesized that unilateral cerebral norepinephrine (NE) spillover, an index of cerebral sympathetic nerve activity (SNA), would be elevated when engaging the baroreflex [via lower-body negative pressure (LBNP; -20 and -40 Torr)] and respiratory chemoreflexes [via carbon dioxide (CO) administration (+8 Torr)], independently, and in combination. Twelve young and healthy participants (5 females) underwent simultaneous blood sampling from the right radial artery and internal jugular vein.

We describe a case of orbital cellulitis with abscess formation following eyebrow piercing complicated by internal jugular vein thrombosis and subretinal abscesses requiring enucleation with orbital abscess drainage. The popularity of body piercing is increasing and physicians should be familiar with the possibility and management of vision-threatening complications of facial piercing. Following left eyebrow piercing, a 20-year-old female experienced increasing periorbital swelling, erythema, chemosis, orbital pain, decreased vision, and concomitant fever, chills, and rhinorrhea.
