1/12. Arteriovenous malformation mimicking femoral osteolysis after total hip arthroplasty.We encountered a case of apparent progressive femoral osteolysis around a well-fixed cementless implant in a young patient. At the time of revision arthroplasty, massive hemorrhaging occurred during exposure and attempted femoral component extraction. Urgent packing of the exposed endosteum with polymethyl methacrylate controlled the bone bleeding. Emergent angiography confirmed an arteriovenous malformation with extensive proximal diaphyseal involvement directly at the site of osteolysis. This arteriovenous malformation was treated successfully with selective arterial embolization and second-stage resection. In retrospect, the index arthroplasty operative note indicated an excessive amount of blood loss, and prerevision radiographs showed osteolysis with uncharacteristic vascular markings. The presence of an osteolytic lesion in total hip arthroplasty should not be assumed to be attributed to polyethylene granuloma, and any atypical radiographic features should prompt further preoperative investigations.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/12. Intraoral vascular malformation and airway management: a case report and review of the literature.A patient with a large airway venous malformation underwent anesthesia for a tooth extraction. The procedure was uneventful until extubation, immediately after which complete airway obstruction resulted. After unsuccessful attempts to relieve the problem, the patient's trachea was reintubated. laryngoscopy showed that the venous malformation in the airway had enlarged and was responsible for the airway obstruction. Another attempt at extubation after corrective maneuvers was again unsuccessful. A tracheostomy was required, which was eventually removed after a complete recovery. Anesthesiologists must be concerned with any airway vascular abnormality. Most abnormalities involving the airway are either hemangiomas or venous malformations. The anesthesiologist must diagnose the problem correctly because even minor manipulation of a venous malformation may result in exsanguination, or the malformation may become engorged and compromise the airway.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
3/12. Osseous regeneration after embolization of mandibular arteriovenous malformation.A mandibular arteriovenous malformation (AVM) is rare, and unawareness of this condition can lead to catastrophic complications. Embolization is an effective means to treat these lesions. The osseous changes and long-term outcomes among the pediatric patients after embolization treatment remain unclear. We present a 6-year-old patient with mandibular arteriovenous malformation who had sustained hemorrhagic shock after a tooth extraction. She was referred to us after stabilization of the hemodynamic condition. The patient received transarterial and direct intralesional embolization. Local infection occurred 3 months after embolization, but was well controlled. Serial computed tomography and panoramic radiographs were performed during follow-up examinations. The imaging studies showed gradual obliteration of the vascular space followed by normal bone regeneration and remodeling. The processes were complete during a period of 2 years. There was no recurrence of the vascular malformation and no abnormal growth of the right side of the mandible after 4 years and 4 months of observation.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
4/12. Bilateral arteriovenous malformation of the mandible.Spontaneous bleeding from the molar gingiva may reflect the presence of a life-threatening vascular malformation. Sporadic reports of exsanguinating hemorrhage in the dental literature warn of the dangers of extraction, although deaths from unrecognized lesions or secondary to mandibular fracture still occur. Arteriovenous malformation (AVM) may be either unilateral or, less commonly, bilateral, and should be suspected in individuals with large lower facial hemangiomata. Two cases of near-exsanguinating hemorrhage from bilateral AVMs are discussed with the long-term management over a 3- to 20-year follow-up. The report underscores the failure of therapeutic embolization and the need for computed tomographic scanning as a corollary to angiography. A newer treatment with direct removal of the AVM and obliteration methods solves the hemorrhagic complications, reduces the potential for steal syndromes, and reduces the potential for recurrence.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
5/12. Fatality from central hemangioma of the mandible.Fatalities from central hemangiomas, including a new case, are reviewed. The importance of a thorough examination of young patients with suspicious gingival bleeding and mobile teeth before extraction is emphasized. The nature of the lesion and the methods of treatment are discussed. In the case reported, there were arteriovenous malformations in the soft tissues surrounding the mandible and a seemingly separate central mandibular lesion. The latter showed rapid growth throughout the mandible, ending fatally after spontaneous bleeding and extraction of the mandibular third molar. During the preceding three years, bilateral external carotid ligation had been performed and numerous conservative measures had been taken, including corticosteroid therapy, injections of Sotradecol, and telecobalt irradiation, all with little benefit.- - - - - - - - - - ranking = 2keywords = extraction (Clic here for more details about this article) |
6/12. Treatment of a central arteriovenous malformation of the mandible with cyanoacrylate: a 4-year follow-up.Large arteriovenous malformations of the jaws are relatively rare, potentially life-threatening lesions. When the lesion is not suspected, extraction of teeth can be fatal. The occurrence and treatment of arteriovenous vascular communications in the head and neck region have traditionally presented most perplexing problems. Traditional treatment has usually involved the obtaining of proximal and distal vascular control and surgical removal of the lesions, when feasible. This article presents a case that is of particular interest because it illustrates the successful use of cyanoacrylate as the only treatment for a large arteriovenous malformation of the left side of the mandible. A 4-year follow-up shows no evidence of the lesion and demonstrates complete regeneration of bone in the same area.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
7/12. Severe hemorrhage from an arteriovenous malformation of the mandible: report of case.A case of a potentially lethal arteriovenous malformation of the mandibular bone in a 6.5-year-old girl is reported. diagnosis is often difficult and the AVM may be discovered only when a tooth is extracted. The intent of the preceding report is to alert dental practitioners to the need for immediate control of abnormal bleeding from an extraction socket, because of the potentially lethal consequences. Failure to respond quickly to profuse bleeding of this type could result in the death of the patient by exsanguination.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
8/12. vascular malformations of the mandible (intraosseous haemangiomas). The importance of preoperative embolization. A study of 9 cases.Haemangiomas of the mandible are relatively rare arteriovenous malformations: 85 cases have been described since 1849. The severe risk of bleeding during tooth extraction or biopsy led us to describe the radiological and angiographic features of this condition. The afferent vessels are the inferior dental, the lingual, and the facial arteries. Preoperative embolization reduces the risk of bleeding at operation. Surgical treatment must assure the complete removal of the lesion. radiotherapy and vascular ligatures are useless and dangerous.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
9/12. Mandibular arteriovenous malformation diagnosed by MR and MRA: a case report.A case of mandibular arteriovenous malformation (AVM) is presented. Prompt diagnosis and appropriate management are essential due to massive bleeding or even death after dental extraction or biopsy. angiography remains the gold standard in detecting the lesion. Magnetic resonance (MR) imaging with spin-echo sequences reveals the vascular malformation as signal-void. MR angiography can demonstrate the nidus, dilated artery and vein. MR imaging and MR angiography can supplement angiography in the diagnosis of mandibular AVM.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
10/12. Arteriovenous malformation of the mandible: life-threatening complications during tooth extraction.This case illustrates how a vascular malformation can turn an ordinary tooth extraction into an emergency situation. arteriovenous malformations are rare and difficult to detect on radiographs. Early warning signs are discussed and surgical treatment is described.- - - - - - - - - - ranking = 5keywords = extraction (Clic here for more details about this article) |
