A 42-year-old man with a history of sudden onset of severe headache followed by consciousness disturbance was brought to our hospital. Radiological examinations revealed subarachnoid hemorrhage, associated with rupture of a left vertebral artery dissecting aneurysm. Initially, internal trapping was attempted via the ipsilateral vertebral artery. However, the microcatheter could not be navigated through the true lumen to the distal side of the vertebral artery. Subsequently, therefore, the guiding catheter was placed in the right vertebral artery, and the microcatheter was retrogradely navigated successfully through the lesion to the proximal side of the left vertebral artery. Finally, the lesion was completely embolized with electrodetachable coils without complications. However, the patient died after the operation because of deterioration of the general condition. The postmortem examination revealed how an intimal flap had interfered with the antegrade navigation of the microcatheter in the lesion. The present case showed that endovascular treatment for a vertebral artery dissecting aneurysm via the contralateral vertebral artery may be a useful option in cases where antegrade navigation of the microcatheter via the ipsilateral vertebral artery is found to be difficult.

The authors report the rare case of a 58-year-old man with segmental arterial mediolysis (SAM) with associated intracranial and intraabdominal aneurysms, who suffered subarachnoid hemorrhage (SAH) due to rupture of an intracranial aneurysm. This disease primarily involves the intraabdominal arterial system, resulting in intraabdominal and retroperitoneal hemorrhage in most cases. The patient presented with severe headache and vomiting. The CT scans of the head revealed SAH. Cerebral angiography revealed 3 aneurysms: 1 in the right distal anterior cerebral artery (ACA), 1 in the distal portion of the A1 segment of the right ACA, and 1 in the left vertebral artery. The patient had a history of multiple intraabdominal aneurysms involving the splenic, gastroepiploic, gastroduodenal, and bilateral renal arteries. He underwent a right frontotemporal craniotomy and fibrin coating of the dissecting aneurysm in the distal portion of the A1 segment of the right ACA, which was the cause of the hemorrhage. Follow-up revealed no significant changes in the residual intracranial and intraabdominal aneurysms. An SAH due to SAM with associated multiple intraabdominal aneurysms is extremely rare. The authors describe their particular case and review the literature pertaining to SAM with associated intracranial and intraabdominal aneurysms.

Background Double origin of the posterior inferior cerebellar artery (DOPICA) has been rarely reported in the literature, with a reported incidence of 1.45%. In contrast, a high concurrence rate of DOPICA and vertebral artery dissecting aneurysm has been reported. Clinical presentation A 61-year old woman presented with vomiting and diplopia with preceding headache. Magnetic resonance imaging (MRI) showed fresh infarction of the left lateral medulla and a vertebral artery dissecting aneurysm of the left vertebral artery. The next day, she exhibited transient loss of consciousness and worsening of headache, and MRI depicted subarachnoid hemorrhage. Four-vessel digital subtraction angiography showed a posterior inferior cerebellar artery (PICA) arising both intracranially and extracranially from the left vertebral artery. Although the dissecting lesion involved the V3 and V4 portion, it did not involve an extracranially originating PICA. Internal trapping of the V3 and V4 portion was chosen as the extracranial channel was expected to supply the PICA territory. This procedure was safely performed. Conclusion Early endovascular intervention should be considered in the treatment of dissecting aneurysm of vertebral artery associated with DOPICA for patients with relatively long lesions even in unruptured cases.

Abstract OBJECTIVE AND IMPORTANCE Dural arteriovenous fistulae (DAVFs) not directly shunting into the cavernous sinus are an infrequent cause of visual dysfunction. An unusual case of a tentorial DAVF associated with visual symptoms related to dysfunction of the anterior and posterior visual pathway is presented. CLINICAL PRESENTATION A 38-year-old woman with a history of long-standing bilateral proptosis experienced a sudden onset of headache and visual disturbances. Ocular examination revealed bilateral episcleral and retinal venous congestion, optic disc paleness, right superior homonymous quadrantanopsia in both eyes, and concentric narrowing of the visual field of the right eye. Angiography revealed a DAVF supplied by a falx branch arising from the left vertebral artery and both middle meningeal arteries, which drained directly into the markedly dilated vein of Galen via the basal vein of Rosenthal and the cavernous sinus into both superior ophthalmic veins. INTERVENTION Endovascular treatment was performed in two consecutive sessions by transarterial embolization with n-butylcyanoacrylate, which resulted in occlusion of the fistula and complete clinical cure, confirmed at the 6-month follow-up examination. CONCLUSION Various neuro-ophthalmological findings may be caused by an arteriovenous lesion remote from the optic organ as a result of rerouting of venous drainage compromising the visual pathway at different locations. Transarterial embolization of a DAVF may result in complete cure if advantageous arterial anatomy allows for flow control and occlusion of the fistulous connection with liquid adhesives.

Spontaneous vertebral artery dissecting aneurysm has been increasingly attributed as a major cause of focal neurological deficits due to vertebrobasilar artery ischemia or subarachnoid hemorrhage (SAH). Although the development of spontaneous vertebral artery dissecting aneurysm (VADA) is rare, de novo VADA after treatment of contralateral vertebral artery (VA) is more less frequently observed. There are only a few reports related to de novo VADA after treatment of the contralateral VA in the medical literature. The mechanisms responsible for de novo dissection after treatment of unilateral VADA are still not clearly understood. In this manuscript, we report an unusual case of a patient with a de novo VADA after placement of a pipeline embolization device (PED) stent on the contralateral VA along with a thorough review of the literature. A 42-years old male patient was referred to the hospital with sudden onset of dizziness, nausea, and vomiting. Initial digital subtraction angiography (DSA) images demonstrated a VADA in the fourth segment of the left VA without the involvement of the posterior inferior cerebellar artery (PICA). There were no significant abnormalities found in the right vertebral artery. He underwent an endovascular pipeline embolization to treat the dissecting aneurysm (DA). Surprisingly, follow-up DSA imaging 14 months after the initial treatment showed a segmental dilatation and narrowing of the right VA, which suggested a de novo VADA on the right side that had occurred postoperatively. This was followed by a tent-assisted coil embolization therapy for occluding this de novo VADA. This patient showed an uneventful postoperative course with no neurological abnormalities. In addition to hemodynamic stress changes, the unique clinicopathological features of dissecting aneurysms may contribute significantly to the pathogenesis of de novo VA dissection. Given that VA in VADA patients may be vulnerable on both sides, it is important to consider the risk of de novo dissection after initial aneurysm treatment. The bilateral vertebral artery has to be carefully observed when treating any VADA patient to prevent any complications.

The central type of Tapia’s syndrome is an extremely rare presentation, characterized by unilateral paralysis of the vagal and hypoglossal nerves, contralateral hemiparesis, or hemihypesthesia. This report describes a case of a middle-aged patient who developed central Tapia’s syndrome due to a right vertebral artery dissecting aneurysm (VADA). The patient complained about swallowing difficulty and odynophagia. Right vocal cord paralysis, mild tongue deviation to the right side, left hypesthesia, and decreased temperature sensation with left hemiparesis were observed in neurologic exams. A right VADA and compression of the medulla oblongata due to the VADA were diagnosed on magnetic resonance imaging. Endovascular flow diversion of the right VADA was performed. After 1 year, all neurological symptoms and vocal cord paralysis were nearly resolved, but left hypesthesia remained with decreased nociception. We present and discuss how a VADA caused those symptoms and propose endovascular flow diversion as a treatment option.

Összefoglaló. Az agyi érrendszer elzáródásos panaszai elsősorban felnőttkorban jelentkeznek, nem ritkák azonban gyermekek esetében sem. A gyermekkori stroke gyakorisága 2,5/1 000 000 fő; ilyenkor általában az arteria carotis interna vagy az arteria cerebri media érintett. Az ischaemiás stroke-ok 25%-a a hátsó keringési rendszer területén keletkezik. Az arteria vertebralis extracranialis szakaszának stenosisa 18%-ban a jobb oldalon, 22,3%-ban a bal oldalon észlelhető. Esetünkben egy 7 éves kisfiú kórtörténetét mutatjuk be, aki facialis paresis, súlyosbodó ataxia és somnolentia tüneteivel került egy megyei kórház gyermek intenzív osztályára. A készült kontrasztos koponya angiográfiás MR-vizsgálaton akut ischaemiás elváltozások voltak láthatók, valamint sejteni lehetett, hogy a bal oldali arteria vertebralis gracilisabb; a hypoplasia azonban csak a beteg egyetemi centrumba kerülése után, az ott elvégzett, a nyaki erekre is kiterjedő TOF - (time of flight) angiográfia és nyaki ultrahang készítését követően bizonyosodott be. A beállított gyógyszeres kezelések hatására az ischaemiát okozó artériás thrombus feloldódott, majd megkezdődött a rehabilitáció folyamata, melynek során a beteg állapota nagymértékben javult. A gyermek kórházba kerülése előtt hónapokkal észlelt, magatartás- és figyelembeli zavarainak romlása felveti a már korábban bekövetkező átmeneti ischaemiás periódusok lehetőségét is. A hátsó keringési rendszert érintő stroke-ok etiológiája változó, többször kerültek már leírásra különböző háttérrel. Esetünkben a fejlődési rendellenesség – ’bow hunter’ szindróma tűnik a legvalószínűbbnek. A készült dinamikus nyaki ultrahangvizsgálat is erre utaló eredményt adott. Időintervallumon belül szóba jöhet az arteria vertebralis thrombosis kezelése endovascularis módszerek segítségével is. Ennek kivitelezhetősége érdekében azonban fontos a mielőbbi pontos diagnózis felállítása a megfelelő képalkotó vizsgálatok segítségével és a betegnek a kezelésére felkészült centrumba juttatása. Orv Hetil. 2021; 162(47): 1902–1907. Summary. Cerebrovascular obstruction primarily affects adults, but it is not uncommon in children either. The incidence of childhood stroke is 2.5/1 000 000 population, usually affecting the internal carotid artery or the middle cerebral artery. The posterior circulatory system is involved in 25% of ischemic strokes. Stenosis of the extracranial section of the vertebral artery is demonstrated in 18% on the right side and 22.3% on the left side. We present the case history of a 7-year-old boy who was admitted to the pediatric intensive care unit of a county hospital with symptoms of facial palsy, progrediating ataxia and somnolence. Contrast-enhanced angiographic MR images of the skull revealed acute ischemic lesions and suggested stenosis of the left vertebral artery, then it was confirmed by TOF (time of flight) angiography of vessels of the neck and cervical ultrasound examination. The arterial thrombus causing ischaemia was eliminated by drug treatment and the rehabilitation process could be started. The patient’s condition improved considerably following that. Deterioration in behavioral and attentional problems of the patient, which had been realised months prior to hospitalisation, raises the possibility of earlier ischemic periods. The etiology of strokes affecting the posterior circulatory system has been described with different backgrounds. In the presented case, a developmental disorder – bow hunter’s syndrome seems to be the most likely one. The result of dynamic cervical ultrasound examination also supported this theory. Treatment of vertebral artery thrombosis with endovascular methods may also be considered within a time interval. However, to make it feasible, it is important to establish an accurate diagnosis as soon as possible by appropriate imaging studies, and to transfer the patient to a specialised center.
