Technique for retrieval of a guidewire lodged in a vena cava filter.

A case in which the guidewire used to place a percutaneous jugular central line became entangled in the limbs of a Trapease inferior vena cava filter is presented. A 7F sheath introducer was fashioned into a monorail system to uncurl the wire's J tip and remove the wire without disturbing the filter's position. This report highlights an increasingly frequent clinical scenario and an inexpensive effective method for resolution.

Controlled tissue expansion with guided bone regeneration.

Guided tissue regeneration techniques are used to create new bone around implant defects and to augment edentulous ridges prior to implant placement. A new technique, tested successfully in baboons, utilizes soft tissue expanders prior to implant placement and tissue regeneration procedures.

Sonographic findings in traumatic hemobilia: report of two cases and review of the literature.

Hemobilia consists of an arteriobiliary fistula, usually due to central liver rupture with bleeding into the biliary tree. It is due to trauma in over 50% of cases, with an increasing incidence of iatrogenically caused hemobilia. The sonographic findings in two cases of traumatic hemobilia are presented and the literature is reviewed.
