Marfan Syndrome: new diagnostic criteria, same anesthesia care? Case report and review.

BACKGROUND

Marfan's Syndrome (MFS) is a disorder of connective tissue, mainly involving the cardiovascular, musculoskeletal, and ocular systems. The most severe problems include aortic root dilatation and dissection. Anesthetic management is vital for the improvement on perioperative morbidity.

CASE REPORT

61-year-old male with MFS, presenting mainly with pectus carinatum, scoliosis, ectopia lens, previous spontaneous pneumothorax and aortal aneurysm and dissection submitted to thoracoabdominal aortic prosthesis placement. Underwent routine laparoscopic cholecystectomy due to lithiasis. Important findings on preoperative examination were thoracolumbar kyphoscoliosis, metallic murmur on cardiac exam. Chest radiograph revealed Cobb angle of 70°. Echocardiogram showed evidence of aortic mechanical prosthesis with no deficits.

DISCUSSION

Preoperative evaluation should focus on cardiopulmonary abnormalities. The anesthesiologist should be prepared for a potentially difficult intubation. Proper positioning and limb support prior to induction is crucial in order to avoid joint injuries. Consider antibiotic prophylaxis for subacute bacterial endocarditis. The patient should be carefully positioned to avoid joint injuries. Intraoperatively cardiovascular monitoring is mandatory: avoid maneuvers that can lead to tachycardia or hypertension, control airway pressure to prevent pneumothorax and maintain an adequate volemia to decrease chances of prolapse, especially if considering laparoscopic surgery. No single intraoperative anesthetic agent or technique has demonstrated superiority. Adequate postoperative pain management is vitally important to avoid the detrimental effects of hypertension and tachycardia.
