Rescue Nuss procedure for inferior vena cava compression syndrome following posterior scoliosis surgery in Marfan syndrome.

PURPOSE: Scoliosis surgery in Marfan syndrome is common, even in the presence of a funnel chest. However, to date, no case has been reported with acute intra-/postoperative decompensation caused by vena cava compression following posterior spinal derotation and fusion.
METHODS: A 15-year-old male patient with Marfan syndrome, a funnel chest and severe scoliosis was treated with surgery for the spinal deformity. Intraoperatively, the patient developed a clinically relevant compression of the inferior vena cava with severe circular depression. Postoperatively, a cava compression syndrome with severe pleural effusion, ascites and enormous swelling of the lower limbs was developed. A conservative treatment of the symptoms, consisting of thoracic drainage and negative fluid balance, failed. Subsequently, the patient was transferred to pediatric intensive care unit for further treatment. Echocardiography and a CT scan demonstrated cava compression syndrome. A rescue Nuss procedure of the funnel chest deformity was performed since conservative treatment failed. The clinical course proceeded without complications and with a decrease in clinical symptoms of inferior inflow congestion. The patient was discharged after almost 3 weeks.
CONCLUSION: The problem of congenital stenosis of the inferior vena cava in Marfan syndrome has not yet been investigated. In the case of simultaneously existing funnel chest and scoliosis in Marfan syndrome, an interdisciplinary discussion is required to decide whether a repair of the funnel chest should be performed first in order to prevent a clinically relevant compression syndrome. For the detection of a preoperatively relevant stenosis of the inferior vena cava, an MRI or thoracic/abdominal CT should be used preoperatively.
