Case Reports
Transesophageal echocardiography diagnosis of tricuspid obstruction by a vena cava tumour.
To present the anesthetic management for excision of a primary tumour of the inferior vena cava. ⋯ Tricuspid obstruction due to postoperative mobilization of a primary tumour of the inferior vena cava was diagnosed by transesophageal echocardiography. Perioperative management particularities of the primary tumour of the vena cava are discussed.

Comparative Study
Anesthesia for cerebral aneurysms: a comparison between interventional neuroradiology and surgery.
To review the anesthetic management of patients with cerebral aneurysms during treatment in the interventional neuroradiology (INR) suite compared with in the operating room. ⋯ There were some differences in the anesthetic management of patients undergoing endovascular treatment of a cerebral aneurysm compared with treatment in the operating room. The patients in the INR suite were sicker and somewhat older and they received less invasive monitoring, but the complication rate and outcome did not differ.

Case Reports
Anesthesia for Cesarean section and posterior fossa craniotomy in a patient with von Hippel-Lindau disease.
To describe the care of a pregnant woman with von Hippel-Lindau disease (VHLD) and intracranial mass lesions. ⋯ Patients with VHLD may have worsening of preexisting lesions or develop other lesions during pregnancy. Some asymptomatic lesions can increase the risk for anesthesia complications. These patients need comprehensive assessment before administration of anesthesia.

To compare the effectiveness of various laryngeal mask airway (LMA) sizes and their performance during positive pressure ventilation (PPV) in paralyzed pediatric patients. ⋯ Use of the LMA in smaller children results in more airway obstruction, higher ventilatory pressures, larger inspiratory leak, and more complications than in older children.

Case Reports
Ambulatory surgery for multi-ligament knee reconstruction with continuous dual catheter peripheral nerve blockade.
Major reconstructive surgery of the knee traditionally requires an extended hospital stay for pain management. Continuous peripheral nerve blockade is an alternative method of pain control but is seldom used in the ambulatory setting. This case illustrates the use of lumbar plexus and sciatic nerve peripheral catheters for major knee surgery using intermittent bolus dosing for outpatient analgesia. ⋯ The use of a lumbar plexus and sciatic nerve peripheral catheter offered an alternative to conventional pain control that worked well in the ambulatory setting. By providing prolonged unilateral lower limb analgesia, extensive knee surgery was performed that would normally require a hospital stay for pain control. Using a bolus dosing method the risk of local anesthetic complications occurring outside of the hospital with a continuous infusion was minimized.
