コイル塞栓術を施行した破裂脳動脈瘤の連続46例を80歳以上(A群)と80歳未満(B群)に分類し、治療成績と予後に関する因子について検討した。その結果、A群は12例、B群は34例であった。A群はB群に比べ症候性脳血管攣縮の発生頻度が有意に高く、腰椎ドレナージ挿入の頻度が有意に低かった。退院時のmodified Rankin Scaleが0-2を予後良好例、3-6を予後不良例としたところ、予後良好例は10例、予後不良例は36例であった。予後良好例はA群0/12例(0%)、B群10/34例(29%)で、A群で有意に少なかった。症候性脳血管攣縮が予後不良に関与する割合はA群4/12例(33%)、B群1/24例(4%)で、A群で有意に高かった。

Ethmoidal dural arteriovenous fistulas (AVFs) are rare intracranial lesions associated with a high risk of intracranial hemorrhage. In particular, this entity with reflux drainage directly into the ophthalmic vein is extremely rare. We report a case of ethmoidal dural AVF with direct drainage of the superior ophthalmic vein (SOV) and inferior ophthalmic vein (IOV), successfully treated by endovascular surgery. A 58-year-old man presented with progressive diplopia. Angiography and contrast-enhanced CT showed an ethmoidal dural AVF supplied via the bilateral anterior ethmoidal arteries and venous drainage through the left SOV and IOV. A transarterial approach through the bilateral anterior ethmoidal arteries was used to place the microcatheter close to the fistula site. After intra-arterial embolization with 20% N-butyl cyanoacrylate, the dural AVF was completely occluded. In patients with good vascular access, endovascular transarterial embolization may be an effective and less invasive treatment strategy for ethmoidal dural AVF.

BACKGROUND: We describe a case of a very unusual complication following a coiling procedure in which the patient developed transient unique cerebral and cerebellar lesions. Lesions were examined not only by magnetic resonance imaging (MRI) but also by positron emission tomography-computed tomography (PET-CT) and proton magnetic resonance spectroscopy ((1)H-MRS). CASE PRESENTATION: A 33-year-old woman presented an incidental 3.7 × 3.3-mm unruptured cerebral aneurysm (CAn) in her basilar artery, which was successfully coiled with balloon assistance. A follow-up brain MRI at 1 and 2 months showed a gradual increase in several white matter hyperintense lesions in the left cerebellar, bilateral occipitotemporal and left parietoccipital lobe during fluid-attenuated inversion recovery (FLAIR). These were the only lesions associated with perfused CAn. However, the patient did not show any additional symptoms such as visual disturbance throughout the entire course. (11)C-methionine-PET (MET-PET) showed an obvious increase in methionine uptake in the lesion corresponding to enhanced areas with gadolinium-enhanced MRI. MRS showed a decrease in the N-acetylaspartate/creatine (NAA/cr) ratio and a slight elevation of the choline/creatine (cho/cr) ratio and a lactate peak in the lesion. A follow-up MRI at 6 and 12 months showed a gradual decrease in the initial hyperintense lesions in FLAIR without any treatment. CONCLUSION: We present a case of an unusual complication after a coiling procedure. Although it is difficult to identify this etiology without a pathological examination, it is importance to increase awareness of such a potential complication arising from coiling procedures, because interventional procedures have become the first choice of treatment for cerebrovascular diseases in many countries.

Spinal dural arteriovenous fistulas (S-dAVFs) are rare vascular malformations of the spine. We experienced a case that presented with rapidly progressive brainstem dysfunction due to venous congestion of cervical dAVFs. A 56-year-old man diagnosed with cervical dAVF four years prior presented with gait disturbance and abnormal thermal nociception on his right side. In addition to the high-intensity lesion from the lower pons to the medulla oblongata on T2-weighted magnetic resonance imaging, diffusion-weighted imaging demonstrated cerebral infarction of the left ventrolateral medulla oblongata. Left vertebral angiography revealed that a feeding artery supplied by the radicular artery at the C4 level formed a fistula with the dilated ascending anterior perimedullary vein. We made a diagnosis of venous congestion due to cervical dAVFs. Numbness on the left upper limb occurred five days after the first symptom. Subsequently, hemiparesis on the left upper limb and swallowing disturbance occurred two weeks after the first symptom. The patient underwent surgical ligation of the dilated abnormal vein, with gradual improvement of his symptoms. Myelopathy due to venous congestion of S-dAVFs usually progresses slowly for several years. However, this case report warns about the possibility that some cases of S-dAVF with rapidly exacerbated symptoms may require prompt therapy.
