RESUMO
Objective To investigate the surgical diagnosis and treatment of late vitamin K deficiency intracranial hemorrhage caused by biliary atresia. Methods Clinical data of six cases of biliary atresia with late vitamin K deficiency intracranial hemorrhage were collected in the Department of Neurosurgery of Tianjin Children’s Hospital from January 2000 to December 2013. Data were analyzed to identify the biliary atresia as soon as possible in the treatment of intracranial hemorrhage and prolonged jaundice in children. Results Six cases (1 male, 5 female), mean age was (16.0±2.6) days, and were treated with external drainage of intracranial hematoma and infusion therapy. In the treatment, children were found jaundice exacerbation and doubted about biliary atresia. After consultation by general surgeons, children were transferred to the department of general surgery for further treatment at an average age of (29.1±1.2) days, and were diagnosed as biliary atresia by intraoperative cholangiography. Conclusion Pediatric neurosurgeon should have a sufficient understanding and make an early diagnosis to late vitamin K deficiency intracranial hemorrhage caused by biliary atresia, to avoid delaying the optimal treatment time of biliary atresia.
