Question

A child of four months old has a hernia and is preparing for surgery. A blood clotting mechanism issue was detected, with Factor XI at 49.8 and Factor XII at 33. What disease could the child possibly have?

Answer

The symptoms and laboratory test results you described lead doctors to consider the possibility of hemophilia in the child. Hemophilia is a genetic bleeding disorder characterized by prolonged bleeding time after minor injuries. The disease is generally incurable, and the key to treatment is to prevent bleeding, regional hemostasis, and prompt supplementation of clotting factors. It is recommended to go to a regular professional hospital for examination and treatment.
