Case Reports
Genicular Radiofrequency Ablation for Treatment of Post Total Knee Arthroplasty Posterior Thigh Pain: A Case Report.
We present a case of a 68-year-old woman with 6 months of chronic unilateral posterior thigh pain after a total knee arthroplasty. The patient's pain was refractory to various treatments. After appropriate diagnostic tests, a genicular nerve block and subsequent radiofrequency ablation were performed. These procedures provided substantial pain relief of her thigh pain at 3 months follow-up.

Ventricular Perforation During Open Surgical Balloon Expandable Mitral Valve Replacement: A Case Report.
A 79-year-old woman with severe mitral annular calcification was scheduled for mitral valve replacement. A SAPIEN 3 valve was implanted in mitral position using an open surgical approach. ⋯ Risk factors specific to the open surgical approach include a decompressed ventricle, decreased annulus to apical distance, and the absence of continuous fluoroscopic and echocardiographic imaging. These create a clinical scenario where risk of ventricular perforation is increased compared with traditional intravascular transcatheter valve delivery.

While an abundance of literature exists describing adverse reactions to vancomycin (eg, nausea, vomiting, red man syndrome, acute kidney injury), there is scarce evidence demonstrating vancomycin anaphylactic reactions requiring cardiopulmonary resuscitation. We report a case of a patient who had 2 separate preoperative episodes of cardiac arrest following vancomycin that occurred 4 weeks apart. Both episodes of anaphylaxis required cardiopulmonary resuscitation, which led to a successful patient outcome. We discuss identification and treatment of vancomycin-induced anaphylaxis.

Case Reports
Brachiocephalic Vein Perforation During Cannulation of Internal Jugular Vein: A Case Report.
We report a rare complication of right brachiocephalic vein perforation during ultrasound-guided cannulation of the right internal jugular vein (IJV) in a patient with a tortuous common carotid artery (CCA). We suspect that the tortuous CCA displaced the IJV, which caused misplacement of the J-tip guidewire into the subclavian vein. ⋯ This was diagnosed by videothoracoscopy. Anesthesiologists should be aware of the possibility of guidewire malposition during IJV catheterization in patients with a tortuous CCA.

Case Reports
Malignant Hyperthermia in a Morbidly Obese Patient Depletes Community Dantrolene Resources: A Case Report.
During resection of a duodenal carcinoid tumor, a 28-year-old morbidly obese woman developed suspected malignant hyperthermia. This hypermetabolic state posed a diagnostic challenge given the similar intraoperative presentation of carcinoid crisis and malignant hyperthermia. ⋯ Current dantrolene dosing recommendations are based on actual body weight despite a paucity of literature in obese patients. We speculate that the prolonged need for dantrolene redosing was from the continuous release of the volatile anesthetic from the patient's adipose tissue.
