1/4. Embolization of a life-threatening mandibular vascular malformation by direct percutaneous transmandibular puncture.vascular malformations of the mandible are uncommon, but often present with significant hemorrhage. Transarterial vessel occlusion has become a valuable primary or adjunctive treatment for such lesions, as well as for most other symptomatic congenital and acquired head and neck vascular anomalies. Permanent embolic obliteration of the malformation requires placement of occlusive material directly into the nidus (core) of the lesion. Prohibitively complex proximal vasculature may prevent successful catheter positioning and lead to failure of traditional embolotherapy. Even optimal placement of arterial embolic material may fail to fully obliterate the nidus, allowing eventual restoration of flow to the lesion due to arterial recanalization. Under such circumstances it may be possible to obliterate the malformation and control lesional hemorrhage by occlusion of the malformation or its venous drainage by direct percutaneous mandibular puncture. In our case, multiple transarterial embolizations failed to sufficiently manage a symptomatic vascular malformation. Successful embolotherapy was performed via direct puncture of the venous side of the malformation through the mandibular cortex. venous thrombosis induced concomitant occlusion of abnormal arteriovenous shunts, resulting in long-term control of life-threatening oral hemorrhage.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/4. Infra red coagulation for bleeding mucosal telangiectasia.The technique of infra red coagulation is well suited to the destruction of superficial blood vessels in the skin and/or mucosal surfaces. A method is described here for the destruction of resistant bleeding telangiectasia of the palate and lip in Osler-Weber-Rendu syndrome.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/4. life-threatening hemorrhage from placement of a dental implant.This report focuses on a potentially fatal hemorrhage arising from dental implant placement in the mandible. Anatomic considerations of the lingual artery and its divisions in the floor of the mouth are discussed. In addition, various methods of controlling bleeding from the floor of the mouth are reviewed. The case presented is unusual in that intraoral ligation of the transected vessel was possible despite the presence of massive sublingual, submental, and submandibular hematomas as well as severely distorted anatomy. This case represents a severe complication resulting from a seemingly minor oral surgical procedure. Those performing endosteal implant placement should be knowledgeable in the management of such complications.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/4. Oral injury caused by fellatio.A 34-year-old Caucasian woman is presented with a circular hemorrhagic lesion located on the soft palate and caused by fellatio. The lesion consisted of erythema, petechiae, dilated blood vessels and vesicles. It healed in a few days. No evidence of the major clinical alternatives such as thrombocytopenia, venereal disease, candida infection or pathomimia were found. Injuries due to fellatio must be considered as an etiological factor to hemorrhagic changes of the oral mucosa, and with a positive history, patients can be spared from other investigations.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
