A 74-Year-Old Man with Severe Comorbidities and Successful Abdominal Aortic Aneurysm Repair with Thoracic Segmental Spinal Anesthesia: A Case Report

Objective: Unusual or unexpected effect of treatment Background: Elderly patients with severe or multiple comorbidities can be at high risk for complications of general anesthesia. This report is of a 74 -year -old man with severe comorbidities, including ischemic heart disease (IHD) and chronic obstructive pulmonary disease (COPD), and successful abdominal aortic aneurysm repair with thoracic segmental spinal anesthesia. Case Report: The patient, aged 74, had previously been diagnosed with severe COPD and IHD. He was classified as American Society of Anesthesiology (ASA) grade IV, diagnosed with an abdominal aortic aneurysm (AAA) measuring 6 cm in diameter, and had to undergo surgical repair of the aneurysm with the insertion of a synthetic graft. Due to a shortage of beds in the ICU and the desire to avoid the complications associated with general anesthesia, the decision was made to proceed with thoracic spinal regional anesthesia, which is not a customary choice for this type of surgery. Spinal anesthesia was administered at the Th10-11 level, utilizing 8.5 mg of Bupivacaine, 50 mcg of Fentanyl, and 4 mg of Dexason. An epidural catheter was placed at the same level. The surgical procedure lasted 145 min and was successfully completed under regional anesthesia. Conclusions: This report has highlighted that developments in spinal thoracic anesthesia mean that this can be a successful alternative to general anesthesia in high -risk patients, even for major emergency surgery.
