Case Reports
Anomalous Connection of Superior Vena Cava to Left Atrium-A Rare Congenital Cardiac Anomaly and Its Implications.
Exclusive drainage of superior vena cava (SVC) into the left atrium (LA) is one of the rare causes of right-to-left connection. Usually, this anomaly occurs in association with other cardiac defects, and is diagnosed in early childhood. ⋯ We describe a case of anomalous connection of SVC to LA with drainage of right upper pulmonary vein into SVC and its implications for the perioperative physician. The patient presented with dyspnea on exertion, cyanosis, and a past history of cerebral abscess.

Patients with cold agglutinin disease who undergo total hip arthroplasty (THA) are rarely encountered. Patients with cold agglutinin disease are very sensitive to cold ambient temperatures and require scrupulous perioperative body-temperature management. ⋯ Thus, perioperative management of patients with cold agglutinin disease undergoing THA requires more than just scrupulous systemic temperature management. Here, we present the successful perioperative management of a patient with severe cold agglutinin disease who underwent THA with a cemented stem.

Thoracic epidurals remain the optimal method for providing postoperative analgesia after complex open abdominal and thoracic surgeries. However, they can be challenging to both place and maintain, as evidenced by a failure rate that exceeds 30%.1 Proper identification of the epidural space and accurate placement of the catheter are critical in order to deliver effective postoperative analgesia and avoid failure.2,3 This case series investigated the difficulty in correctly identifying the proper vertebral level for thoracic epidural catheter procedures when performed in the lateral decubitus position.

We present a 54-year-old man who developed an unexpected thenar space compartment syndrome after robotic laparoscopic surgery, which was caused when the radial arterial pressure tubing was pulled too tightly around the base of the thumb while changing the surgical position. A conventional method of securing the tubing by looping it around the thumb appeared to be the primary cause. This complication went unnoticed during the surgery because the arm was tucked out of sight; there were no remarkable findings on monitoring. This case highlights the risks of looping tubing around the thumb, especially if continual inspection is not possible.

Case Reports
A Case Report of an Incidental Ultrasound Finding in a Suspected Malignant Hyperthermia Patient.
Malignant hyperthermia (MH) is a rare but life-threatening genetic disorder of the skeletal muscles triggered by inhalation anesthetics or succinylcholine. A 49-year-old female developed symptoms of MH shortly after a lumbar surgery. ⋯ On receiving dantrolene, her symptoms improved within 20 minutes; a subsequent ultrasound revealed no fasciculations. Although halothane contracture testing was not available, the fasciculations that resolved with dantrolene administration in a MH suspected patient opens up a new potential avenue of diagnostics.
