Few reports have described the successful treatment of stroke caused by acute vertebral artery (VA) origin occlusion by endovascular surgery. We describe the case of a 68-year-old man who experienced stroke due to left acute VA origin occlusion. Cerebral angiography showed that the left VA was occluded at its origin, the right VA had hypoplastic and origin stenosis, and the basilar artery was occluded by a thrombus. ⋯ A balloon-assisted guiding catheter was navigated through the stent and a thrombectomy was performed using the Penumbra system. The patient's symptoms gradually improved postoperatively. Balloon-assisted catheter guidance through a vertebral artery stent permitted a successful thrombectomy using the Penumbra system and may be useful for treating stroke due to VA origin occlusion.

Arterial ischaemic stroke is an important cause of morbidity in children. Timely diagnosis is necessary for acute stroke treatment but can be challenging in clinical practice. Due to a paucity of data there are no specific recommendations regarding the use of mechanical thrombectomy devices in current paediatric stroke guidelines. ⋯ No clinical improvement was seen after administration of intravenous thrombolysis. Subsequent mechanical thrombectomy with a second-generation stent-based thrombectomy device resulted in successful recanalization and clinical improvement. To our knowledge, this is the first report of mechanical thrombectomy in a child with acute embolic stroke caused by atrial myxoma.

We report our experience in treating the anterior condylar dural arteriovenous fistula (DAVF) and confirm the location of the coils in the follow-up images after successful endovascular treatment. We retrospectively reviewed the 14 patients with anterior condylar DAVF treated successfully in our institute. Twelve of them had CT or MR follow-up images. ⋯ We found 100% of the coils at the anterior condylar veins inside the hypoglossal canal, 54.2% at the lateral lower clivus, and only 14.2% at the anterior condylar confluence which is ventrolateral to the anterior orifice of the hypoglossal canal. Intravascular coiling is the treatment of choice in patients with anterior condylar DAVF. All the coils were found at the anterior condylar veins inside the hypoglossal canal after successful treatment.
