We present a patient with spinal epidural arteriovenous fistula presented with subdural hematoma and progressive myelopathy. Transarterial embolization using NBCA results in complete obliteration of fistula without complication. The pathophysiology, angioarchitexture of the lesion and strategy for its cure would be discussed.

The devices and methods of endovascular recanalization therapy (ERT) have been rapidly developed and changed since PROACT II trial. Emerging as a treatment option in addition to intravenous or intra-arterial thrombolysis, mechanical thrombectomy is currently being further developed and investigated as a potential first-line and stand-alone treatment. This review highlights and summarizes the recent clinical series and trials of the available devices and methods of ERT focusing on the multimodal approach.

OBJECTIVE: The aim of this study was to evaluate the efficacy of endovascular therapy as a primary treatment for spinal dural arteriovenous fistula (DAVF). METHODS: The authors reviewed 18 patients with spinal DAVFs for whom endovascular therapy was considered as an initial treatment at a single institute between 1993 and 2006. NBCA embolization was considered the primary treatment of choice, with surgery reserved for patients in whom endovascular treatment failed. RESULTS: Surgery was performed as the primary treatment in one patient because the anterior spinal artery originated from the same arterial pedicle as the artery feeding the fistula. Embolization was used as the primary treatment modality in 17 patients, with an initial success rate of 82.4%. Two patients with incomplete embolization had to undergo surgery. One patient underwent multiple embolizations, which failed to completely occlude the fistula but relieved the patient's symptoms. Spinal DAVF recurred in two patients (one collateral development and one recanalization) during the follow-up period. The collateral development was obliterated by repeated embolization, but the patient with recanalization refused further treatment. The overall clinical status improved in 15 patients (83.3%) during the follow-up period. CONCLUSION: Endovascular therapy can be successfully used as a primary treatment for the majority of patients with spinal DAVFs. Although it is difficult to perform in some patients, endovascular embolization should be the primary treatment of choice for spinal DAVF.

Simultaneous occurrence of remote intracerebral hemorrhage (ICH) and intracranial aneurysmal subarachnoid hemorrhage is very rare. We report on a case of concurrent hypertensive ICH at the left thalamus and rupture of an intracranial aneurysm at the bifurcation of the single A2 segment of the anterior cerebral artery in a 64-year-old woman, which was clipped previously, with review of the literature. To our knowledge, this is the first case report demonstrating bleeding of previously clipped aneurysm with simultaneous hypertensive ICH. Hypertensive crisis following ICH seems to have provoked rupture of the residual aneurysm.

Thirthy-eighthy cases of abdominal aortic aneurysm(AAA) were surgically treated between January 1991 and December 1995 at the Dept. of Surgery, Chonnam University Hospital. Patients were divided into 20 elective cases and 18 emergency cases and analysed on the basis of sex, age, chief complaints, associated diseases, size of aneurysm, operating time, mortality and cause of death. The initial presentation was usually abdominal or back pain in elective cases, but palpable mass and abdominal distension in emergency cases were ruptured. There was no positive relationship between the size of AAA and the incidency of the rupture. There were no deaths in elective cases, but 12 ruptured AAAs died in 18 emergency cases(66.7%). Overall surgical mortality was 31.3%. The causes of death were postoperative bleeding(5), acute renal failure(3), myocardial infarction(3), and sepsis(1). For AAAs, surgical intervention is recommended and operation must be performed before rupture regardless of the size.

PURPOSE: To determine, by means of a phantom study, the distortion-related factors and appropriate iodine concentration for three-dimensional reconstruction rotational angiography. MATERIALS AND METHODS: Four phantoms were created: crossed metal rods, one metal rod, one contrast rod, and a contrast rod under water. Iodine concentrations were 300, 250, 200, and 150 Img/ml, respectively. For each phantom, rotational angiography was performed in the rotational, right-angled (90 degree to rotational), intermedial (45 degree), close to rotational (20 degree), and close to right-angled (70 degree) planes. Two-dimensional projection images were transferred to a workstation at which 3D images were produced using the volume rendering technique. Image quality in each plane was evaluated in terms of opacity, homogeneity, and margin sharpness, which were graded as low, intermediate or high by two neuroradiologists who used images obtained in the right-angled plane as the standard reference. The same assessors evaluated in terms of the same parameters, cross-sectional images obtained at the central, intermedial, and peripheral portions of one metal rod positioned in the right-angled, close to right-angled, and intermedial planes, and in order to compare the values at different sites, one neuroradiologist measured the horizontal and vertical diameters of each cut image. RESULTS: Three-dimensional images of all four phantoms were high quality in the close to right-angled and intermedial plane, but in the rotational and close to rotational plane were degraded. In particular, metal rod images obtained in the rotational plane were poor for all three items. In these two planes, image quality was better for the contrast rod than the metal rod, and at 200 and 250 Img/ml concentrations than at 300 and 150 Img/ml concentrations. There was no significant difference in image quality, nor in measured values of the diameter between cut images. CONCLUSION: A three-dimensional image was more distorted when a linear object was placed at a lesser angle to the rotational plane and when inherent X-ray attenuation was greater, a finding which must be closely related to the beam-hardening artifact. Distortion was least at 200-250 Img/ml of iodine concentration, the concentration thought to be most appropriate for in-vitro 3D angiography.
