1/44. Treatment of mandibular arteriovenous malformation by transvenous embolization: A case report.BACKGROUND: arteriovenous malformations (AVMs) of the mandible are relatively rare and potentially life-threatening lesions. Treatment is usually difficult. This study presents a case with high-flow AVM of the mandible in which most of the AVM were occluded by transvenous coil embolization. methods: Transvenous embolization using several size 57 microcoils and 3 Gianturco coils was performed through a right femoral vein access. The small residual AVM was occluded by superselective transarterial injection of cyanoacrylate. RESULTS: angiography after embolization showed almost complete obliteration of AVM. Panoramic radiograph 2 years after treatment confirmed reossification. There was no recurrence of the symptoms in a follow-up evaluation 2 years later. CONCLUSION: Transvenous coil embolization may be a safer and more effective method in the treatment of mandibular AVM.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
2/44. Preparing a hemimandibulectomy patient for delayed reconstructive surgery.A rehabilitation device was designed and used before a reconstructive orthognathic procedure in an adult patient with a severe facial asymmetry. The asymmetry developed as a result of a left hemimandibulectomy in childhood. With this prototype device, the remaining hemimandible was gradually brought into its natural position and dynamics in order to accommodate a graft. The goals were to improve esthetics and function, reduce the chance of the remaining hemimandible not adapting to the graft, and reduce the risk of secondary TMJ pathosis after the mandibular reconstruction.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
3/44. Surgical technique for the treatment of high-flow arteriovenous malformations of the mandible.The high-flow intraosseous arteriovenous malformation is a problematic vascular lesion which may affect bone and the dentition. Variable clinical presentations of this anomaly have resulted in a gamut of treatment modalities being reported ranging from simple curettage, resection, radiotherapy, sclerosing injections, and various forms of embolization, to immediate replantation of the resected segments. Embolization techniques alone have not been universally successful and have often resulted in rapid development of collaterals from surrounding vessels. Definitive treatment has usually involved complete surgical resection (when feasible) either alone, or in combination with other modalities such as embolization. jaw resection, however, is deforming and leaves a defect often requiring subsequent reconstruction of the hard and soft tissues and replacement of any teeth lost with the resected segment. We report a surgical technique to treat mandibular arteriovenous malformations, which permits ligation of the feeding vessels and provides access allowing for complete removal of the intraosseous lesion. At the same time it not only prevents facial deformity by preserving the mandibular bone and oral soft tissue, but also, and more importantly, may preserve the dentition as well.- - - - - - - - - - ranking = 2keywords = mandible (Clic here for more details about this article) |
4/44. Endovascular management of a bleeding mandibular arteriovenous malformation by transfemoral venous embolization with NBCA.A 13-year-old boy presented with an arteriovenous malformation (AVM) involving the left mandible that bled after intraoral biopsy. The AVM was treated on an emergency basis by primary intravenous delivery of n-butyl cyanoacrylate after transfemoral catheterization, resulting in complete anatomic and clinical cure.- - - - - - - - - - ranking = 0.5keywords = mandible (Clic here for more details about this article) |
5/44. Arteriovenous malformation of the mandible.A recent case of a vascular malvormation involving the mandible prompted the review of this subject. There are less than 80 cases of this rare but serious disease reported in the literature. There is no accepted standard treatment, but recent contributions have improved the safety and effectiveness of therapy.- - - - - - - - - - ranking = 2.5keywords = mandible (Clic here for more details about this article) |
6/44. Arteriovenous malformation of the mandible: embolization and direct injection therapy.Arteriovenous malformation (AVM) of the mandible is a rare entity but one that can be potentially fatal as a result of massive hemorrhage. Traditional treatment involved extensive surgical resection of the mandible. With the advent of improved endovascular techniques, interventional radiology is now the best method to control active hemorrhage and ultimately cure these lesions. The authors describe three cases of successfully treated mandibular AVM by percutaneous and/or endovascular techniques.- - - - - - - - - - ranking = 3keywords = mandible (Clic here for more details about this article) |
7/44. Conservative treatment of arteriovenous malformations of the mandible.A modified technique is reported on the treatment of arteriovenous malformations in the mandibular body. The technique consists of highly selected embolization and piecemeal removal of the lesion through burred holes made in the cortex. This way the mandible and the teeth may be saved in selected patients.- - - - - - - - - - ranking = 2.5keywords = mandible (Clic here for more details about this article) |
8/44. Arteriovenous malformation of the mandible: review of literature and case history.vascular malformations of the jaws can lead to disastrous complications, but there seems to be no consensus as to their treatment. The literature presents the pathophysiology and clinical aspects of these lesions, as well as the divergent views of the authors. Treatment by catheterization and embolization, with direct transosseous injection of cyanoacrylate, appears to be the least harmful and most permanent treatment in certain conditions, as evidenced by the case of this 9-year-old patient having a high-flow mandibular vascular malformation- - - - - - - - - - ranking = 2.0031238464212keywords = mandible, jaw (Clic here for more details about this article) |
9/44. Craniofacial arteriovenous metameric syndrome (CAMS) 3--a transitional pattern between CAM 1 and 2 and spinal arteriovenous metameric syndromes.We report a rare case of craniofacial arteriovenous metameric syndrome (CAMS) 3 arteriovenous malformations of the mandible, left VIII nerve and petrous bone. The patient, a 19-year-old girl, presented with profuse gingival bleeding during a dental procedure and we diagnosed CAMS 3 during a pre-embolisation angiogram. The distribution of the vascular lesions suggests that CAMS 3 is intermediate CAMS 1 and 2 and spinal arteriovenous metameric syndrome (SAMS).- - - - - - - - - - ranking = 0.5keywords = mandible (Clic here for more details about this article) |
10/44. 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 = 0.5keywords = mandible (Clic here for more details about this article) |
