BACKGROUND: Endovascular coil embolization is an accepted treatment option for intracranial aneurysms. However, the coiling of aneurysms with an incorporated artery (IA) poses a high risk of IA occlusion. Here we report our experience of endovascular coil placement using a technique that avoids IA occlusion in aneurysms with IAs. METHODS: Over a 6-year period, 185 patients harboring 206 intracranial aneurysms underwent endosaccular coiling. Forty-two of these patients with 45 aneurysms were treated by coil placement to avoid IAs occlusion...

Rotational vertebral artery occlusion (RVAO) is a well-documented surgically amenable cause of vertebrobasilar insufficiency. Traditionally, patients have been imaged using dynamic rotational angiography. We report a case of RVAO in which intraoperative indocyanine green angiography (ICGA) was used to confirm adequate surgical decompression of the VA. A 57-year-old female who presented with multiple episodes of syncope provoked by turning her head to the right. Rotational dynamic angiography revealed a dominant right VA that became occluded at the level of C5/6 with head rotation to the right...

Vertebrojugular fistulas have been described in the literature associated with blunt or penetrating injury and iatrogenic or spontaneous development. Its presentation may be broad and may include symptoms of radiculopathy, vertebrobasilar insufficiency, tinnitus, and bruit. However, so far, no direct cardiac complications had been reported. Here, we describe a case of an 86-year-old female who suffered a C5 vertebral fracture secondary to a ground-level fall that was initially treated conservatively due to the onset of new severe atrial fibrillation...

Vertebrobasilar insufficiency (VBI) provoked by physiological head rotation is known as rotational vertebral artery syndrome (RVAS) or Bow Hunter syndrome. RVAS most often occurs at C1-2 level with head rotation and presents with symptoms of VBI. Several previously published studies have reported RVAS at subaxial sites (V2 segment), however, tumor-induced RVAS has never been reported. The authors report the first case of RVAS at V2 segment due to compression from a spinal tumor. A 71-year-old man presented with symptoms of dizziness provoked by head rotation or neck extension...

BACKGROUND: Rotational vertebral artery occlusion is a rare syndrome characterized by vertebrobasilar insufficiency secondary to position-dependent occlusion of the vertebral artery. Most cases reported in the literature have been attributed to osteophytic compression, either from the occipital condyle or within the transverse foramen. However, vertebral artery dissection secondary to motion in the setting of anomalous anatomy has not been reported. CASE DESCRIPTION: To the authors' knowledge, rotational vertebral artery occlusion and dissection secondary to anomalous entrance into the transverse foramen have never been reported...

BACKGROUND: Tortuous or occluded vertebral arteries (VAs) can make the endovascular treatment of vertebrobasilar insufficiency impractical. Bypass surgery is an option, but a craniotomy of the posterior fossa is complicated when physiologic vessels must be abandoned. We report 3 cases of refractory vertebrobasilar insufficiency with different presentations requiring problematic approaches in which the patients were treated by different hybrid strategies. CASE DESCRIPTION: Patient 1 had severe stenosis of right VA ostium with right V1 segment tortuosity and was treated by right VA ostium transposition during which the proximal subclavian artery was blocked by a balloon guide catheter...

Bow hunter's syndrome (BHS) is a rare cause of vertebrobasilar insufficiency that occurs when the vertebral artery (VA) is occluded on rotation of the head and neck. This dynamic occlusion of the VA can occur anywhere along its course after it arises from the subclavian artery. Although most cases are associated with compression by osteophytes, cervical spondylosis, or lateral disc herniation, BHS has a highly variable clinical course that depends on the patient's specific anatomy. Therefore, it may be important for clinicians to be aware of anatomical variants that predispose individuals to BHS...

BACKGROUND: Revascularization of the upper posterior circulation (UPC), including the superior cerebellar artery (SCA) and posterior cerebral artery (PCA), may be necessary as part of the surgical treatment of complex UPC aneurysms or vertebrobasilar insufficiency. The existing bypass options have relative advantages and disadvantages. However, the use of a superficial temporal artery graft (STAg) in a bypass from the internal maxillary artery (IMA) to the UPC has not been previously assessed...

Vertebrobasilar insufficiency leading to posterior circulation infarcts caused by congenital hypoplasia of the bilateral transverse foramina at the C2 level, affecting the caliber and flow of the bilateral distal cervical vertebral arteries in an adult, has not been previously reported. A 41-year-old male presented with episodic dizziness for a period of 1 year prior to consultation. Computed tomography angiography of the head and neck demonstrated congenital hypoplasia of the bilateral C2 transverse foramina, with absence of the vertebral arteries in each of the foramina and collateral reconstitution of diminutive intracranial vertebral artery segments...

A dissecting aneurysm of the vertebral artery in the extracranial portion is a rare pathology. It may either have a symptom-free course or induce a clinical picture of vertebrobasilar insufficiency. To the main methods of surgical treatment belong endovascular techniques and resection of an aneurysm with shunting of the V3 segment of the vertebral artery. Presented in the article is a clinical case report regarding successful surgical management of a dissecting aneurysm of the extracranial portion in a young woman presenting with a clinical course of vertebrobasilar insufficiency and treated by means of ligation of the vertebral artery in the V1 segment and autovenous shunting from the external carotid artery to the V3 segment of the vertebral artery...
