[Answered]: Exercise 1: PREOPERATIVE DIAGNOSIS: Thyroid…

Exercise 1: PREOPERATIVE DIAGNOSIS: Thyroid nodule, right lobe POSTOPERATIVE DIAGNOSIS: Thyroid cyst, right lobe PROCEDURE: Aspiration with possible resection or ethanol injection DESCRIPTION: The patient is taken to the operating room where she was given general anesthesia. A roll was placed under the shoulder to extend the neck. The right neck and chest were prepped with Chloraprep and draped in sterile fashion. The patient was intubated and monitored intraoperatively because the nodule/cyst was identified at a volume of over 15 mL on ultrasound and found near the laryngeal nerve. Using ultrasound guidance to identify the largest loculation of the cyst, 18 ml of fluid was aspirated and sent for rapid cytological evaluation. The results returned as benign and, therefore, no dissection was indicated. Further ultrasound suggested that the largest loculation of the cyst could be safely injected and the decision was made to perform percutaneous ethanol injection for sclerosis of the cyst. 15 mL of 95% ethanol was injected into the cyst using ultrasound guidance. Anesthesia was reversed and the patient was taken to recovery in satisfactory condition. Questions: 1.1. How many procedures are represented in this report and what are they? 1.2.
