Savitz SI, Ronthal M, Caplan LR. A case of medulla oblongata compression by tortuous vertebral arteries presenting with spastic quadriplegia .
10: 1075-5. Vertebral artery medulla compression syndrome (VAMCS) is a very rare condition manifesting as different neurological focal deficits. 6. He noticed weakness of both legs and gait disturbance at the age of 58 years and his symptoms progressively worsened during the following several months. The clinical features can be transient or permanent, can be motor, cerebellar or vestibular. Recent clinical experience suggests that this condition may be clinically under-appreciated and that patients with vascular compression of the brainstem are being misdiagnosed. Much less is known about vertebral artery compression of the medulla. BACKGROUND Intracranial arteries in the subarachnoid space may compress the brain parenchyma and cranial nerves. To describe a series of patients with vertebral arteries compressing the medulla oblongata. A case of medulla oblongata compression by tortuous vertebral arteries presenting with spastic quadriplegia. In this study, we report five new patients with magnetic resonance angiographic findings of a tortuous large ectatic VA causing compression and distortion of the medulla oblongata. Dilated tortuous dominant V4 segment of the left vertebral artery compressing the medulla and cervico-medullary junction, still with no underlying signal abnormality of the medulla. Takashi Kamada, Takahisa Tateishi, Tamayo Yamashita, Shinji Nagata, Yasumasa Ohyagi, Jun-ichi Kira. Vertebral artery compression syndrome. We report a 58-year-old man showing spastic paraparesis due to medulla oblongata compression by tortuous vertebral arteries. In some rare circumstances, compression of the medulla So far, only 12 sporadic cases of medulla oblongata compression caused by an ectatic and tortuous vertebral artery (VA) have been described (10, 11, 15, 18, 19, 25, 27, 34, 39, 42, 44). Much less is known about vertebral artery compression of the medulla. Vertebral artery compression of the medulla. No definite cranial nerve compression or vascular looping on thin slice T2 images. The symptoms related to a tortuous vertebral artery and some techniques for surgical treatment are discussed. Savitz SI(1), Ronthal M, Caplan LR. This patient also had increased signal on T2-weighted imaging studies within the right medial medulla, representing either wallerian degeneration or damage from branch artery occlusion or compression (Figure 4C).
So far, only 12 sporadic cases of medulla oblongata compression caused by an ectatic and tortuous vertebral artery (VA) have been described (10, 11, 15, 18, 19, 25, 27, 34, 39, 42, 44). Much less is known about vertebral artery compression of the medulla. Surgical treatment was effective. 2019. Front Neurol. In 1985 Jannetta [ref. The left vertebral artery distal to the origin of the posterior inferior cerebellar artery was then sectioned, decompressing the medulla oblongata. Takashi Kamada, Takahisa Tateishi, Tamayo Yamashita, Shinji Nagata, Yasumasa Ohyagi, Jun Ichi Kira. Takashi Kamada, Takahisa Tateishi, Tamayo Yamashita, Shinji Nagata, Yasumasa Ohyagi, Jun Ichi Kira. INTERVENTION: In both patients, the compressed medulla oblongata was treated by detaching the vertebral artery from the medulla oblongata, shifting it, and anchoring it to the nearby dura mater. ... and prior reports have concentrated on the pressure effects of basilar artery ectasia. 2013 Volume 53 Issue 5 … Compression most commonly occurs at the ventrolateral surface of medulla. Much less is known about vertebral artery compression of the medulla. BRAINSTEM COMPRESSION SYNDROME CAUSED BY VERTEBROBASILAR DOLICHOECTASIA ... was performed with left vertebral artery exposure. In this study, we report five new patients with magnetic resonance angiographic findings of a tortuous large ectatic VA causing compression and distortion of the medulla oblongata. Vertebral artery compression of the medulla. Much less is known about vertebral artery compression of the medulla. In all cases he found a vascular compression on the left ventral side of the medulla oblongata, mostly caused by an elongated vertebral artery or a PICA loop. The vertebral artery and the medulla were separated by insertion of a Teflon sponge in between them (Fig 2 and Fig 3). 63: 234-41. Department of Neurogy; Research output: Contribution to journal › Article. The dura was opened and the tortuous vertebral artery was found in a groove over the medulla. Most arterial compressive lesions have been attributed to dolichoectasia in the vertebral-basilar system, and prior reports have concentrated on the pressure effects of basilar artery ectasia.
Prospective case studies. Magnetic resonance imaging clearly revealed the vascular compression in these patients. Keywords: tortuous vertebral artery, spastic paraparesis, microvascular decompression procedure. Postoperatively, both patients are Author information. In the case of chronic ataxia with combined medullar sings, medulla compression caused by vertebral artery dolichoectasia needs to be included in the differential diagnosis encompassing cerebellar atrophy, stroke or drug overuse. Arch Neurol.
The case of a 36-year-old male with symptomatic brainstem compression by vertebral artery (VA) treated by means of microvascular decompression (MVD) and a review of the literature is presented. JOURNALS FREE ACCESS.
