1/229. Surgical management of angiographically occult spinal dural arteriovenous fistulae (type I spinal arteriovenous malformations): three technical case reports.

    OBJECTIVE AND IMPORTANCE: Spinal dural arteriovenous fistulae (Type I spinal arteriovenous malformations [AVMs]) have been recognized as a treatable cause of progressive myelopathy. The diagnosis and characterization of these lesions rest heavily on spinal angiography. CLINICAL PRESENTATION: We present three patients whose clinical presentations were consistent with a spinal dural AVM but whose spinal angiographic results were negative. INTERVENTION: The surgical treatment of these angiographically occult spinal AVMs is described. In retrospect, in each case, the feeding vessel to the AVM was injected but not seen. CONCLUSION: Some spinal dural arteriovenous fistulae will be angiographically occult. If the clinical and radiographic presentations strongly suggest the presence of an arteriovenous fistula, surgical exploration should be considered.

2/229. Multiple cerebral arteriovenous malformations (AVMs) associated with spinal AVM.

    The co-existence of multiple cerebral arteriovenous malformations (AVMs) and a spinal AVM is extremely rare. A 22-year-old man suddenly developed severe headache. Computed tomography (CT) scan showed intracerebral haemorrhage in the left occipital lobe. cerebral angiography revealed eight AVMs; four were in the right frontal lobe and two each were in the right temporal and left occipital lobe, respectively. A huge high-flow spinal AVM was found incidentally. He had no other vascular lesions such as hereditary haemorrhagic telangiectasia. A left occipital craniotomy was performed and the ruptured left occipital AVMs were removed. Further therapeutic treatment was refused. To our knowledge, except for one autopsy case, this is the first reported patient with multiple cerebral AVMs with a spinal AVM. We discuss the characteristics of this case and review reported cases with cerebral and spinal AVMs.

3/229. spinal cord arteriovenous malformations in two patients with hereditary hemorrhagic telangiectasia.

    We report two cases, in first cousins, of spinal arteriovenous malformations (AVMs) of the perimedullary fistula type and hereditary hemorrhagic telangiectasia (HHT). Spinal AVMs are a rare clinical presentation of HHT, but can be the first manifestation in a child with this disorder. The importance of considering a coexisting disorder of vascular dysplasia, such as HHT, when a child presents with a spinal AVM is discussed.

4/229. natural history of congenital arteriovenous fistula.

    There is no more difficult lesion to manage than congenital arteriovenous fistula. The advanced lesions are extremely vascular and unless they lend themselves to total excision, prompt recurrence is the rule. For the same reason, embolization is not successful and as the major feeding vessels are occluded, access to the tumor becomes more and more limited. In order to obliterate the tumor, it must be destroyed at the microvascular level. So far, only ethanol has proved effective in this regard, and this agent must be used conservatively to avoid excessive destruction of normal tissue and systemic damage.

5/229. Transcatheter embolization of arteriovenous malformations in Cowden disease.

    A patient with Cowden disease and multiple arteriovenous malformations (AVMs) that resulted in high output heart failure is described. Cowden disease is a familial syndrome characterized by endodermal, mesodermal and ectodermal dysplasia causing benign and malignant tumors of the skin, breast, gastrointestinal tract, and thyroid gland. Our patient had gastrointestinal polyposis, a right renal tumor, a left lung tumor, an adenomatous goiter, and typical dermatologic findings such as facial papules, acral keratosis, gingival papillomatosis and hemangiomas. AVMs were observed in the pelvis, cervical vertebra, liver, and right supraclavicular area. Transcatheter embolization was performed 7 times for the pelvic AVMs, but the effect decreased with repetition and the patient died of heart failure 2 years after the first embolization. The serum levels of tissue plasminogen activator (t-PA), platelet-derived growth factor (PDGF), hepatocyte growth factor (HGF), vascular endothelial growth factor (VEGF), and transforming growth factor beta1 were high, suggesting that these angiogenic molecules may play a role in the pathogenesis of AVMs in Cowden disease.

6/229. Tentorial meningioma encroaching the transverse sinuses and sigmoid sinus junction area associated with dural arteriovenous fistulous malformation: a case report.

    A 62-year-old woman was evaluated for tinnitis and headache. magnetic resonance imaging and angiography revealed the coexistence of a tentorial tumor encroaching the junction of the right transverse-sigmoid sinuses, and dural arteriovenous fistulous malformation (AVFM) of the right transverse sinus. AVFM was not manipulated at all during the surgery. The pathology was fibroblastic meningioma. Postoperatively, the dural AVFM completely disappeared on follow-up angiography. The fistulas were occluded also after surgery, even though there was no manipulation of the AVFM. It is suggested that the right dominant transverse-sigmoid sinuses are partially occluded by tentorial meningioma, developing the dural arteriovenous fistula of the right transverse sinus. An acquired origin of the dural AVFM was suggested in this case.

7/229. scimitar syndrome with pulmonary arteriovenous fistulas.

    Right abnormal pulmonary venous return into the inferior vena cava associated with abnormal fissure, dextrocardia, and systemic arterial supply of a variable degree, are the characteristics of the scimitar syndrome. We report on a patient in whom this rare syndrome was associated with pulmonary arteriovenous fistulas within the involved lung.

8/229. Pulmonary arteriovenous malformations: lung transplantation as a therapeutic option.

    Multiple pulmonary arteriovenous malformations (PAVM) constitute an uncommon cause of respiratory disability. They may lead to severe hypoxaemia via right-to-left shunts and are sources of substantial mortality and morbidity. Conservative surgical resection has been proposed as the treatment of choice. More recently, percutaneous balloon or coil embolization of the feeding vessels offered an efficacious and safe alternative therapy for patients whose fistulas are too numerous to excise. This study reports an unusual case of respiratory disability in a patient with multiple and microscopic pulmonary arteriovenous malformations who failed to respond to embolotherapy and who received a double lung transplantation with good initial outcome.

9/229. Congenital arteriovenous malformations of the face. Report of a case.

    arteriovenous malformations (AVM) are uncommon vascular abnormalities which can be either developmental defects present from birth, or acquired ones, secondary to trauma. They may cause local swelling and discomfort, and also may present a potential for severe bleeding. Traumatic AVM are usually single fistulous channels, whereas congenital lesions are most often multiple interconnections of vessels of varying caliber that result in a diffuseness which renders clini-al delineation and treatment difficult. The nature of the lesion is determined by the stage of development of the vascular system during which it develops. Congenital lesions range from finely channelled capillary hemangiomas to large-bore, high-flow A-V fistulas. Most lesions are not observed at birth, but become manifest later in life; minor trauma and endocrine change are implicated as the stimuli for the initiation of hemodynamic activity. The diagnosis is clinical, with confirmation by arteriography. The treatment has not been completely satisfactory in all cases. Surgical intervention has been used most often, but newer techniques include cryotherapy and muscle embolization.

10/229. Large intraosseous arteriovenous malformation of the maxilla - a case report with review of literature.

    Large intraosseous arteriovenous malformations (AVM) of the maxilla are rare lesions, which are probably hamartomas. We report a case of an 8-year-old child who presented with exsanguinating hemorrhage after an attempted dental biopsy. The management of dental intraosseous AVMs includes transarterial embolization and direct intralesional injection of liquid acrylic (NBCA). This approach avoids mutilating surgery and its sequelae in children. We present this case for its rarity and the intralesional use of acrylic glue in its management.
