A 55-year-old man presented with difficulty breathing, chest pain, and disturbance of consciousness, and was transferred to our hospital. Initial whole body CT revealed a diffuse subarachnoid hemorrhage(SAH)with severe pulmonary edema that was considered neurogenic in origin. He received controlled ventilation under sedation and conservative care for the SAH. One day after the onset of the SAH, his left pupil suddenly became dilated to 6mm, with no reaction to light. Head CT showed no new bleeding. Subsequent CT angiogram revealed a right internal carotid-posterior communicating artery aneurysm(IC-PC AN)with a posterior-lateral projection; however, no vessel abnormality was observed in the left anterior or posterior circulations...

Two cases of ruptured blood blister-like internal carotid artery aneurysms for which low flow bypass was sufficient to attain successful treatment of trapping are reported. In the acute stage of rupture, it is troublesome to perform accurate examinations of tolerance to ischemia like balloon occlusion test(BOT)for estimating the required amount of bypass flow. In our cases, X-ray angiography perfusion(XAP)analysis was introduced, which could be performed in a couple dozen seconds without room-to-room transfer of patients, following the ordinary examination of diagnostic digital subtraction angiography...

A nearly 80-year-old man with a history of radiotherapy (RT) and total laryngectomy for laryngeal cancer 25 years previously presented with a rapidly growing mass on the right side of his neck. A huge pseudoaneurysm (pseudoAN) was detected at the right carotid bifurcation, though angiography performed four years previously had shown total occlusion of the internal carotid artery. Stent-assisted coil embolization enabled aneurysm sac shrinkage. Clinicians must be aware that the stump of an arterial occlusion associated with RT can change into a pseudoAN over the long term and must provide follow-up in such cases...

A traumatic internal carotid artery (ICA) aneurysm is rare and difficult to treat. Trapping of ICA is commonly performed owing to the difficulty of directly approaching ICA aneurysms. Recently, coiling the aneurysm itself was recommended if possible. However, it is controversial which of methods are best to completely treat aneurysm. We present the case of a 74-year-old man, who had experienced a head injury 8 years previously, with recurrent severe epistaxis. An ICA aneurysm was detected on computed tomography...

BACKGROUND: Ophthalmoplegia secondary to a traumatic dissecting aneurysm in the cavernous segment of internal carotid artery (ICA) is a relatively rare entity. Anticoagulant or antiplatelet therapy is the preferred treatment option for carotid dissections. However, endovascular interventions are noninvasive and alternative methods to surgery, especially in cases of aneurysms that do not respond to medical therapy. CASE REPORT: We report of a 19-year-old man presenting with left-sided, total ophthalmoplegia after a traffic accident...

Background Double lumen balloon catheters (DLBCs) are currently used in the treatment of intracranial aneurysms, especially when involving balloon or stent-assisted coiling. The existing DLBCs allow the delivery of self-expandable stents but do not offer the possibility to deploy flow-diverters. Despite the increasing use and success of flow-diverters, there have been numerous reports of procedural complications such as early in-stent thrombosis or delayed distal embolization. It seems that these complications can be avoided by correct stent positioning and adequate wall apposition, achieved either by manoeuvres with the microguidewire and/or microcatheter or by performing balloon angioplasty following an exchange guidewire manoeuvre...

The introduction of flow diverting stents, particularly for treatment of petrous to supraclinoid internal carotid artery aneurysms, has greatly impacted endovascular treatment of intracranial aneurysms. Despite their high efficacy, complications, such as ischemic events, distal hemorrhage, or problems with stent deployment, remain a significant concern. We present the first reported case of acute distal migration of a Pipeline Embolization Device (PED). A 24-year old female underwent elective placement of a PED for treatment of a left paraclinoid internal carotid artery aneurysm...

Background Intracranial wide-neck aneurysms at the arterial bifurcations, especially in the aneurysms where the bifurcating branches emanate directly from the base of the aneurysm, have been particularly difficult on which to perform endovascular treatment. The 'Y'-configuration, double stent-assisted coil embolization is an option for the treatment of these difficult aneurysms, allowing the closure of the aneurysm, preserving the parent arteries. Material and methods In a nine-year period, 546 intracranial aneurysms in 493 patients were treated at our center by endovascular approach...

Concomitant occurrence of severe extracranial large vessel stenosis and an ipsilateral intracranial aneurysm is often detected incidentally, but the optimal therapeutic strategy is not clear. Several reports have investigated whether simultaneous carotid artery stenting and coil embolization, or multi-stage therapy is better. These treatment strategies are still controversial because simultaneous therapy will decrease the risk of aneurysm rupture, but may also increase the risk of thromboembolic complications...
