AVMs is not a neoplasm, but a congenital developmental anomalies.$^{5)}$ In oral and maxillofacial area, the high recurrence rate and more facial disfigurement give a difficult problem to surgen and patient.$^{8)}$ Conventional treatment modality nowadays is presurgical embolization and surgical resection. In treatment planning, we consider the possibility of complete surgical resection and the esthetics of soft tissue reconstruction. But, two things are very difficult to achieve. We present a patient with AVMs in left upper lip, he had presurgical embolization with Ivalon and Bucrylate, and conservative surgical procedure. So we present this possible treatment modality.

Mandibular arteriovenous malformations(AVM) are relatively rare and potentially life threatening lesions. Surgical treatment consists of wide resection of the mandible, which is difficult and potentially hazardous due to significant blood loss during surgery. Therefore, some authors advocate that transvenous embolization may be a safer and more effective method in the treatment of mandibular AVM. We report a treatment case of mandibular AVM in a 9-year-old-girl for episodes of spontaneous bleeding for 6 days using by selective transarterial embolization, direct puncture embolization and microcoil embolization.

Arteriovenous malformations of the face and scalp are uncommon. We report a patient with facial AVM feeding from external carotid artery. This 26-year old man presented with an arteriovenous malformation involving left forehead. The patient first noted a coin-sized lesion on the site 20 years previously after blunt trauma which progressively enlarged. Surgical resection of AVM was performed after ligation of feeding artery.

The arteriovenous malformation (AVM) is an anomaly of capillary development that results from direct connection between branches of artery and vein without intervening capillary bed. The neurogenic tumors have a tendency to various types of degeneration. Recently, we experienced a 73-year old man with a mass in left supraclavicular area. The intraoperative findings showed severe adhesions with cervical plexus, like a neurogenic tumor. Finally, the mass was revealed as AVM. We report a unique disease pattern with a literature review.

Cervicomedullary junction arteriovenous malformation(AVM) is extremely rare. The authors present a case of a cervicomedullary junction AVM in a 31-year-old woman presenting with recurrent intraventricular hemorrhage (IVH). Magnetic resonance imaging revealed the AVM(of a size of approximately $2{\times}2.5{\times}4cm$) extending from a lower medulla to C2-3 level. Vertebral angiography demonstrated a tightly coiled vascular mass with multiple feeders (radiculomedullary arteries) and irregular-shaped aneurysm at distal part of feeder originating at right C-1 level. The patient underwent superselective embolization of upper nidus and the aneurysm. The pertinent literature is reviewed, and diagnostic and therapeutic implications are discussed.

After surgical operation in patients with arteriovenous malformation (AVM), normal pressure perfusion breakthrough (NPPB) is one of the major complications. Brain perfusion SPECT with acetazolamide stress was known to be useful to evaluate the vascular reserve in several neurological and neurosurgical conditions. The authors performed acetazolamide brain perfusion SPECT in patients with AVM and compared the brain perfusion in the post-operative clinical courses. The acetazolamide brain perfusion SPECT was helpful in defining the prognosis of the patients with AVM. We describe 4 patients with AVM who had acetazolamide brain perfusion SPECT to examine the prognosis.

본 논문에서 뇌동정맥기형에 대해 포톤나이프로 정위적 방사선 수술을 시행한 후 방사선학적으로 10명의 환자중 6례에서 완전 폐색, 4례에서 부분적 폐색을 보였으며, 특히 3cm이하의 작은 뇌동정맥기형 7례중 6례에서 완전 폐색을 보였다(완전 폐색율 : 85.7%). 모든 환자에서 방사선 수술로 인한 방사선학적 합병증의 발병은 없었다. 신경학적으로도 모든 환자에서 방사선 수술 전에 보이던 증상들이 호전을 보였다. 포톤나이프 방사선 수술 시스템은 이미 실험적으로 안정성이 검증된 것으로 이 논문에서 임상적으로 방사선 수술의 안정성 및 정확성을 다시 확인할 수 있었다. 정위적 방사선 수술은 지금까지 치료 불가능했던 부위에 생긴 병소, 수술이나 다른 치료방법으로 완전 제거에 실패한 경우, 노인환자나 다른 내과적 질환으로 수술이 어렵거나 수술적 치료를 거부하는 환자에서도 좋은 치료 방법으로 사용되어지며, 특히 뇌 중요부위나 심부병변에 위치한 경우 또는 최대직경이 3cm 이하의 소 동정맥기형으로 발견 당시 출혈량이 많지 않고 신경학적 결손이 경미한 환자에서 좋은 적응증이 되리라 사료된다.

Parasplenial arteriovenous malformations(AVMs) are rare vascular malformations which have distinct clinical and anatomical features. They are situated at the confluence of the hippocampus, isthmus of the cingulate gyrus and the gyrus occipitotemporalis medialis. These lesions are anterior to the calcarine sulcus and their apex extends towards the medial surface of the trigonum. Posterolaterally, these lesions are in close proximity to the visual cortex and optic radiation. The objectives in the surgery of parasplenial AVMs are complete resection of the lesions and preservation of vision. These objectives must be achieved with comprehensive understanding of the following anatomical features :1) the deep central location of the lesions within eloquent brain tissue ; 2) the lack of cortical representation of the AVMs that requires retraction of visual cortex ; 3) deep arterial supply ; 4) deep venous drainage ; 5) juxtaposition to the choroid plexus with which arterial supply and venous drainage are shared. A 16-year-old female student presented with intraventricular hemorrhage from a right parasplenial-subtrigonal AVM. The lesion, fed by posterior cerebral artery and drained into the vein of Galen, was successfully treated by the inter-hemispheric parietooccipital approach. To avoid visual field defect a small incision was made on precuneus anterior to the calcarine sulcus. In this report, the authors describe a surgical approach with special consideration on preservation of visual field.

We experienced a case of patient of incomplete spinal cord injury following slipping off his clothes. He had complications : both leg paresisㆍboth arm weaknessㆍurine disturbanceㆍboth leg & arm sensory disorder . We could treat these complications with the methods of medical treatments ; acupunctureㆍmoxa therapyㆍherb-medicationㆍelectro-acupuncture & muscle exercises. We obtained results that motor grade and muscle atrophy were improved.

The arteriovenous malformation, an uncommon lesion, is a direct communication between an artery and a vein that bypasses the intervening capillary bed. The authors experienced two cases of arteriovenous malformation in 17-year-old and 18-year-old female patients who had suffered from mandibular pain and gingival bleeding. As a result of careful analysis of clinical and angiographic radiological examinations, we diagnosed them as arteriovenous malformations, and the results were as follows : 1. Main clinical symptoms were dull pain and gingival bleeding on the mandibular body area, and reddness, pain on palpation, thrill and palpitation in the lesional sites were also observed. 2. Radiographically, well-defined radiolucent lesions with multiple osteolytic defects were observed. In radio-nuclide scan, increased uptakes of radioisotope were observed in the lesional sites. 3. Increased venous shunt supplied by the facial, lingual and inferior alveolar arteries was observed in angiography. After embolotherapy was performed, no recurrence was reported during 3 to 6 months follow up.
