Introduction:The role of nurses in post-operative care after major surgery must follow well-established routines, as interdisciplinary communication is essential, directing care and minimizing the risk of adverse events, providing quality and safe care for the patient. Objectives: To deepen knowledge about nursing care in the postoperative period after descending thoracic aortic aneurysm repair. Methodology: Descriptive narrative research work, of a qualitative nature. The information contained in this work was obtained through a literature review. Results: Surgical treatment of descending thoracic aortic aneurysm has a high morbidity and mortality rate, endovascular treatment aims to exclude the aneurysm from circulation. The approach is performed percutaneously, generally via femoral access. After carrying out the procedure, the patient requires intensive care in the immediate post-operative period. For this surgery, specific care in the ICU is essential, mainly continuous monitoring of vital signs; monitoring the puncture site, monitoring bleeding; monitoring of lower limb ischemia; monitor lower limb mobility; monitor blood pressure signals, maintaining a target MAP of 80-100mmhg. Conclusion: It is understood that one of the main objectives of post-operative care for complex procedures is to prevent the occurrence of complications, thus requiring the nurse to have specific knowledge about the various surgeries, thus being able to interfere in the recovery, identify their main complications and act effectively to promote patient recovery.
