A clinical analysis of six cases of mandibular central hemangioma Hu Shunguang Guang Dong Med (China) 1992:257-8 This paper describes six cases of central mandibular hemangioma, All the patients were relatively young, aged 5-28 years. They all had had severe bleeding after extraction or spontaneously. Four
vein. Nine dogs had their external and internal jugular vein ligated. Two dogs were left that way, while seven dogs had a polytetrafluoroethylene (PTFE) vessel prosthesis replacing the lost part of the internal jugular vein. The following observations were made: 1) The caliber of the contralateral internal vein became 1.5-2 times bigger after unilateral ligation of both jugular veins. 2) A significant increase of intracranial pressure occurred after bilateral ligation. 3) All dogs with the PTFE prosthesis survived, but the two dogs without died within 2-3.5 h. Histopathologic examination of the brains confirmed
the diagnosis of increased intracranial pressure. 4) A significant decrease of intracranial pressure was seen after restoration of venous drainage by the PTFE prosthesis. 5) The vessel prostheses were all patent when the dogs were killed. This study showed that vessel repair after (SBRND) by P T F E vessel prosthesis may be of practical value for some patients with advanced head and neck cancer. PEI-KUN LO
of them were in shock. All patients had some swelling of the mandible, and the overlying gingival mucosa was bluish purple. Radiographs showed expansion of the mandible with diffuse, osteolytic, multilocular destruction. The mandibular canal was widened and expanded downward. The mandibular foramen was also widened. All tumors were limited to one side of the mandible. Ligation of the external carotid artery did n o t stop the bleeding. Therefore, ligation of the inferior alveolar artery was
done by dissecting the lingual periosteum after identifying the neurovascular bundle. This measure stopped the bleeding in all cases. In five cases, the mandibular lesion was curetted, and, in one case, a continuity resection was done. The method described may be recommended for patients with central hemangioma that present with uncontrollable bleeding. PEI-KUN LO
