RESUMEN
A novel technique for gaining IV access in a mouse model is presented. Using a cut-down approach, the facial vein is identified through an incision from anterior to the external auditory meatus to posterior to the lateral ispilateral canthus. A small gage needle (30gauge) may be inserted to inject medications. A high success rate (93%) as determined by direct visualization is achieved. The technique would prove especially useful for animals slated for kinematic testing as the incision does not interfere with the animal's ventral surface.

Invasive hemodynamic monitoring has become standard in the management of aneurysmal subarachnoid hemorrhage. This study is a retrospective analysis of 630 Swan-Ganz catheters placed in 184 patients with aneurysmal subarachnoid hemorrhage. Evaluation of complications demonstrated a 13% incidence of catheter-related sepsis (81 of 630 catheters), a 2% incidence of congestive heart failure (13 of 630 catheters), a 1.3% incidence of subclavian vein thrombosis (8 of 630 catheters), a 1% incidence of pneumothorax (6 of 630 catheters), and a 0% incidence of pulmonary artery rupture. In the management of patients with aneurysmal subarachnoid hemorrhage, invasive hemodynamic monitoring continues to be an important tool with acceptable complications.

Lipomas of the cerebellopontine angle are rare, although well described in the literature. A review of the literature with an emphasis on pathogenesis and management is presented.
