A year after her first childbirth, she presented with headache, recurrent scleritis, hypertension, bilateral absent lower limb pulses and right femoral bruit. CT angiogram revealed concentric thickening of the aorta and complete occlusion of the infrarenal aorta, with a saccular aneurysm 18 mm in diameter in the distal thoracic aorta at the T10 level. She was started on immunosuppressants and antihypertensives. During the current pregnancy, she received multidisciplinary care and underwent an elective LSCS with intrauterine contraceptive device (IUCD) placement at term under spinal anaesthesia. Postoperatively, nitroglycerine infusion followed by oral labetalol was administered for hypertension. She was discharged on day 10 with regular follow-up.
