In Reply.— Adventitial tears of the vertebral arteries during a breach or otherwise difficult delivery may well result in hypoplasia of the vertebral arteries as suggested by Yates.1 It is doubtful, however, that such an injury would result in the anomalous cerebral vascular supply demonstrated in our patient.2 It seems more likely that the origin of the right posterior cerebral artery from the right internal carotid may represent persistance of the fetal vascular pattern. This concept might be supported by the absence of the posterior communicating artery.

Objective: The purpose of this study was to explore the effect of endovascular therapy on posterior communicating artery-infundibular dilatation aneurysms. Methods: A total of 15 patients with ruptured aneurysms caused by posterior communicating artery-infundibular dilatation who were treated in our neurosurgical center from January 2015 to December 2018were included in this study. They were performed with bilateral internal carotid angiography and vertebral angiography and treated with endovascular method. The modified Rankin Scale (mRS) was used for clinical follow-up for 18 months. Results: There were 10 patients in the posterior communicating artery-infundibular dilatation aneurysms with non-fetal posterior cerebral artery. Among them, 8 patients were treated with coil-alone embolization. Immediate imaging showed infundibular dilation residual in 6 cases and no contrast filling in either infundibular dilation or aneurysm in 2 case. Another 2 were treated with stent-assisted coiling embolization, and immediate imaging showed no contrast filling. Of the 5 patients in posterior communicating artery-infundibular dilatation aneurysms with fetal posterior cerebral artery, 4 were only coiled in the aneurysm sack with contrast filling in infundibular cones, and 2 were treated with stent assisted coiling. Among the 10 patients with non-fetal posterior cerebral artery, 3 showed recurrence, 4 showed stable images, 2 were also stable with no contrast filling in infundibular dilation or aneurysm and 1 was lost to follow-up. Among the 5 patients with fetal posterior cerebral artery, 1 showed stable images, 3 showed recurrence and 1 was lost to follow-up. Conclusions: For posterior communicating artery-infundibular dilatation aneurysms with non-fetal posterior cerebral artery, stent-assisted coiling of aneurysm embolization combined with occlusion of cones is effective to prevent or reduce recurrence.

ObjectiveHeading disorientation is a type of pure topographical disorientation. Reported cases have been very few and its underlying mechanism remains unclear. We report an unusual presentation of a 60-year-old man with recurrent transient heading disorientation heralding an acute posterior cerebral artery infarction.DesignCase report.ConclusionAcquired injury to the right retro-splenial region can result in a specific variant of topographical disorientation known as heading disorientation that may present as an atypical transient ischaemic attack-like symptom heralding acute cerebral infarction.

We report the case of a patient with subarachnoid hemorrhage and three aneurysms arising from the posterior communicating artery (Pcomm)-P1 complex, treated with endovascular coiling and competitive flow diversion. The largest and likely ruptured Pcomm aneurysm was treated with traditional coiling. Two smaller potentially ruptured aneurysms arose from the distal right posterior cerebral artery (PCA) P1 segment. After a failed attempt to treat with conventional flow diversion across the PCA-P1 segment, the P1 aneurysms were successfully treated with competitive flow diversion distal to the PCA-P1 segment from Pcomm to the P2 segment. Over 12 months, competitive flow diversion redirected flow to the right PCA territory via the internal carotid artery-Pcomm-P2, reducing the size of the PCA-P1 segment and obliterating the P1 aneurysms. Competitive flow diversion treatment should be considered for aneurysms occurring at the circle of Willis when traditional methods are not feasible. Herein, we introduce a novel classification for competitive flow diversion treatment.

ABSTRACT: We studied the arterial circle in the brain of five specimens of the Alouatta belzebul primate. The material had the arterial system perfused (water at 40°C), injected with stained latex (Neoprene 650), fixed in aqueous formaldehyde solution (10%) and dissected for vessel verification. The arterial circle of this primate is composed of two vascular systems: the vertebra-basilar and the carotid ones, which anastomose to close the arterial circuit. In the caudal portion of the arterial circle, there are the vertebral arteries and their branches: the rostral spinal artery and the caudal inferior cerebellar artery. The anastomosis of the vertebral arteries gives rise to the basilar artery. It presented an anatomical variation at the beginning of its path, forming a double basilar artery, called arterial island. In its course, it emitted branches giving rise to the rostral inferior cerebellar artery, the pontine arteries, the rostral cerebellar arteries, the satellite rostral cerebellar arteries and its terminal branch, the caudal cerebral artery, which presented itself in two segments: the pre-communicating one and post-communicating, joining the internal carotid artery and originating the caudal communicating artery. This group of arteries and anastomoses enclose the caudal portion of the arterial circle. From the right and left internal carotid arteries begins the rostral portion of the arterial circle, which consists of the right and left rostral cerebral arteries and the right and left middle cerebral arteries. The rostral cerebral arteries anastomose into a single trunk, giving rise to the interhemispheric artery, and in A. belzebul and Sapajus libidinosus, the rostral communicating artery is absent. The interhemispheric artery goes to the midbrain region and the corpus callosum knee divides into pericalous artery and callosarginal artery, which will supply the pre and post-central regions of the cerebral hemispheres of this species, as well as other non-human and human primates. It is noted that in the first part of the left rostral cerebral artery, there is a direct inosculation between the recurrent branch of the rostral cerebral artery and left middle cerebral artery to supply the entorhinal region. This fact also occurs in Pongo spp. The middle cerebral artery travels along the lateral sulcus where it emits several superficial branches to irrigate the superior and inferior lateral cortical regions of the frontal, parietal and temporal lobes. It is not part of the arterial circle but is the terminal branch of the internal carotid artery. A. belzebul can be considered to depend on two sources of supply to the brain: the vertebra-basilar and carotid systems, contributing to the intervention of veterinarians during clinical and surgical procedures in other primates, as well as the preservation of wild animals.

We report on a patient with visual agnosia for line drawings and silhouette pictures following cerebral infarction in the region of the right posterior cerebral artery. The patient retained the ability to recognize real objects and their photographs, and could precisely copy line drawings of objects that she could not name. This case report highlights the importance of clinicians and researchers paying special attention to avoid overlooking agnosia in such cases. The factors that lead to problems in the identification of stimuli other than real objects in agnosic cases are discussed.

Posterior Communicating Artery Aneurysm

There are many potential anatomical variations in the connection between the internal carotid artery and the posterior circulation through the posterior communicating artery (PCoA). We describe the endovascular treatment of an aneurysm arising near the origin of the PCoA belonging to a transitional type posterior cerebral artery. Coil embolization subsequently resulted in thrombo-occlusion of the adjacent PCoA causing thalamic infarction even though sufficient retrograde flow had been confirmed pre-operatively by Allcock's test.

The analysis of medical histories of 129 patients aged 20 to 59 years, who suffered acute cerebrovascular disorders (AСVD) of the ischemic type (IT), and participated in ATO-JFO was carried out. Anomalies of cerebral arteries were found in all of them. A significant role of hypoplasia of the right posterior cerebral artery, aplasia of the posterior connective, left anterior cerebral and anterior connective, as well as pathological S-shaped tortuosity of the internal carotid artery, hypoplasia of the vertebral arteries and their combinations in the development of acute cerebrovascular disorders in ATO members was established.
