Takayasus's arteritis in pregnancy. Case report and literature review.

BACKGROUND AND OBJECTIVES Takayasus's Arteritis (TA) is a chronic, inflammatory, progressive, idiopathic disease that causes narrowing, occlusion, and aneurysms of systemic and pulmonary arteries affecting especially the aorta and its branches. During pregnancy, one should pay special attention to these patients. The objective of this report was to present the peripartum anesthetic care of a patient with TA and a review of the literature. CASE REPORT This is a 31-year old gravida who underwent exchange of the aortic arch and placement of a metallic aortic valve for TA four years ago. She had no complications during pregnancy, and she was admitted at 34 weeks of pregnancy for anticoagulation management. Elective cesarean section was performed at 39 weeks with continuous epidural anesthesia. Fractionated doses of local anesthetic were administered to guarantee slow installation of the blockade. The patient remained hemodynamically stable and was transferred to the ICU in the postoperative period. CONCLUSIONS Several complications can affect gravidas with TA. Careful patient evaluation, treatment of TA complications, and anestheticsurgical planning are fundamental. Maintenance of perfusion is the main concern in these patients, and neuraxial blocks may be used without harming the mother and fetus. In patients with compensated TA complications, monitoring does not differ from that routinely used in cesarean sections. Continuous epidural anesthesia with slow installation maintains hemodynamic stability and allows monitoring cerebral perfusion through the level of consciousness. To avoid postoperative hypoperfusion or hypertensive complications patients should be monitored in an intensive or semi-intensive care unit for 24 hours.
