In Myasthenia Gravis, thymectomy is indicated when a thymoma is present.

Explanation:
Thymic tumors can drive the autoimmune process seen in myasthenia gravis, so removing the thymus is indicated when a thymoma is present. A thymectomy removes the tumor and often reduces abnormal immune activity against acetylcholine receptors, which can improve MG symptoms and lessen the need for medical therapy. The other procedures target different conditions (carotid artery disease, spinal decompression, brain surgery) and do not address thymic tumors or MG pathology.
