Massive portal venous gas embolism after scuba diving.

Introduction: Portal venous gas from a diving injury is an infrequent finding and only a few cases are described. We report a case of severe decompression sickness (DCS) associated with a massive amount of gas in the portal and mesenteric veins.

Case Report: A 49-year-old man suffered from DCS after two deep dives on the same day.

Direct transoral approach to C2 for percutaneous vertebroplasty.

Percutaneous vertebroplasty was performed via a transoral route in a 70-year-old woman with a C2 metastasis of thyroid origin involving anterior vertebral elements. Complete pain relief was obtained after an uncomplicated minimally invasive procedure. This preliminary experience demonstrates that a transoral approach under fluoroscopic control can provide safe access to the upper cervical spine at C2 level.
