ABSTRACT

Thrombectomy is a routine or common practice for treating organized portal vein thrombosis (PVT) during liver transplantation. However, this procedure is often performed in a blinded fashion and can result in insufficient thrombectomy or devastating consequences such as injury to the retropancreatic portal vein where prompt repair is very difficult. To overcome these drawbacks for blind thrombectomy, we herein describe a new technique that makes complex thrombectomy safe and easy under direct ultrasound vision. This procedure is readily available and highly reproducible and can be used as the standard procedure for treating extensive PVT.

ABSTRACT

A 13-year-old boy was presented to the Department of Neurosurgery, Saiseikai Fukuoka General Hospital for further examinations concerning abnormal findings in the skull radiogram taken when he struck his head. His physical features showed some characteristics the same as those of pycnodysostosis as follows--proportionate dwarfism, prominent forehead, short spoon-shaped fingers, bilateral exophthalmos. A skull radiogram revealed widely open cranial sutures with no healing of the fracture and craniotomy which was performed for an acute epidural hematoma 6 years ago. Furthermore, the mandible was hypoplastic with a virtual loss of mandibular angle. CT of the soft tissues showed somewhat dilated cortical sulci and ventricles without any structural abnormalities in the brain. CT of bone algorithm revealed specific characteristics of this disease. The paranasal sinuses were quite hypoplastic. Especially in the maxillary sinuses, frontal sinuses and mastoid air cells, none of developments of sinuses were noted, even though the middle and internal ear seemed to be normal. Moreover, the ethmoid and sphenoid sinuses were noted, although their developments were poor. The appearance of skull base was normal, including the inlets and outlets of cranial nerves or vessels and synchondroses. However, the density of the skull base, especially in the diploe, was higher than normal in Hansfield number. Furthermore, detailed measurements of skull base demonstrated that the skull base itself was also dwarfism. Pycnodysostosis is a generalized skeletal disease whose cardinal features are moderate generalized osteosclerosis and dwarfism. However, the detailed observation on the cranium by CT has not been reported. In our study, the development of sinuses in bones with intramembranous ossification are worse than that with endochondral ossification.(ABSTRACT TRUNCATED AT 250 WORDS)
