“…We used the term SAD when there was presumable occlusion of the AchA or its branches without any evidence of carotid disease or cardiogenic embolism. However, as AchA itself is not a deep perforating artery, its occlusion might not be regarded as an SAD in a strict sense [14]. Nevertheless, we used the term in this study partly because AchA is still a small artery arising from the large ICA [6], and partly because previous authors have also described this condition as SAD [6,18] or small vessel occlusion [1].…”

“…The heterogeneous results of the clinical features and stroke mechanisms in previous studies may in part be due to the different proportion of pure PLIC lesions included in the studies. Indeed, cardioembolisms or LAD have been considered important stroke mechanisms in studies on patients with lesions extending beyond the PLIC [1,6,14]. …”

“…All MRI images were reviewed, and patients having infarction in the AchA territory were assessed using the model by Tatu et al [15], with particular attention to those with symptomatic lesions on the PLIC. pAchA infarction was diagnosed when the DWI-identified lesion was confined to the lower part of the PLIC (below the level of the thalamus), as the superior part and the genu portion of the PLIC receive the blood supply mainly from the lenticulostriates [12,13,14]. On the contrary, dAchA infarction was diagnosed when patients had additional lesions in other parts of the AchA territory, including at least one of the following structures: the LGB, the crus cerebri, and the medial temporal lobe [10] (fig.…”

“…Furthermore, vascular imaging workup was not complete [1,3,6,7,10,11]. More importantly, although the posterior limb of the internal capsule (PLIC) is mainly supplied by AchA, there is anatomical variation in the vascular supply, and the PLIC may also be supplied by perforators arising from the middle cerebral artery (MCA) [12,13,14]. Thus, unless other areas such as the medial temporal area or the lateral geniculate body (LGB) are concomitantly involved, we cannot be absolutely certain that lesions limited to the PLIC are due to AchA occlusion.…”

Background: Studies investigating the clinical features and stroke mechanisms of anterior choroidal artery (AchA) infarction have reported inconsistent results. This may be partly due to different degrees of inclusion of patients with isolated posterior limb of the internal capsule (PLIC) lesions, which may be supplied by lenticulostriate arteries rather than AchA. The purpose of this study was to investigate clinical features and stroke mechanisms of AchA infarction, with particular attention to the above problem. Methods: We evaluated patients with AchA infarction assessed with diffusion-weighted imaging and magnetic resonance angiography, who were admitted to the Asan Medical Center from July 2001 to April 2011. Probable AchA (pAchA) infarction was diagnosed when the lesions were confined to the lower part of the PLIC, while definite AchA (dAchA) infarction was diagnosed when the lateral geniculate body, the uncus, or the cerebral peduncle were concomitantly involved. We assessed imaging findings, stroke mechanisms, and clinical features, and investigated the differences between patients with dAchA infarction and those with pAchA infarction. Results: We identified 127 patients with AchA infarction: 34 with dAchA infarctions, 90 with pAchA infarctions, and 3 without PLIC lesions. The most important stroke mechanism was small artery disease (SAD), followed by large artery disease (LAD). In patients with LAD, distal internal carotid artery (ICA) disease was a relatively important cause of stroke. The dAchA group, as compared with the pAchA group, was more frequently related to cardioembolism (12 vs. 2%, p = 0.03), distal ICA steno-occlusion (35 vs. 2%, p = 0.001), severe neurologic deficits (higher National Institute of Health Stroke Scale scores and more severe limb weakness), and less often associated with SAD (56 vs. 78%, p = 0.02). Conclusion: In general, SAD was the most important stroke mechanism for AchA infarction followed by LAD. However, dAchA infarction and pAchA infarction differ in that the former was more often associated with cardioembolism, distal ICA steno-occlusion, a worse clinical status and less often associated with SAD than the latter. The different proportion of patients with pure PLIC lesions included in previous studies may have led to inconsistent and confusing results, which should be considered to gain a proper understanding of AchA infarction.

“…In 1916, John Sebastian Bach Stopford (1888-1961), a professor of anatomy in Manchester, discussed and reviewed the study of brainstem vascularization by following in Duret's footsteps and providing commentary [26] . As for Alexander Kolisko (1857-1918) working in Vienna, in 1891 he contested the carotid origin of the anterior choroidal artery as described by Duret in 1874 [27,28] , who pioneered vascular neurology in France in the early 20th century, added details to and completed the description of brainstem and diencephalon circulation initiated by Duret 50 years earlier [31][32][33][34] .…”

Henri Duret (1849-1921) was a surgeon whose training started in the laboratory of Jean-Martin Charcot and Alfred Vulpian at La Salpêtrière in 1874. Using injections of colored gelatine, Duret was the first to describe the distribution of supply arteries in the brainstem and then in the cortex. His descriptions correlated irrigated territories, infarcted zones and secondary neurological deficits. He focused his 1878 thesis on experimental studies of brain trauma and localized the origin of disturbances in autonomic function and vigilance to the brainstem. He linked these disturbances to microhemorrhages affecting the medulla and pons, which are now known as Duret hemorrhages. Over 40 years, he authored numerous publications on digestive and gynecological surgery and on teaching in these areas. In 1905, another of his innovative works was published, which covered brain tumours, their clinical manifestations, the pathophysiological consequences of intracranial hypertension and the corresponding surgical treatments. This little-known treatise is in fact a pioneering work in neurosurgery, published well before the more familiar works of Victor Horsley and Harvey Cushing.

Brain infarcts and the aging hippocampus does anatomy fit the hypothesis?

The article by Wu and colleagues 1 arguing that hippocampal formation is targeted differentially by diseases of late life is interesting and deserves careful consideration. They posit 2 that diabetes and brain infarcts may affect different regions of the hippocampus, therefore suggesting different mechanisms that are involved, with vascular anatomy and supply playing different roles in the case of brain infarcts. There are some questions regarding anatomy and brain infarct recovery we would like to investigators to clarify. We would like the authors to further clarify the topographic patterns of infarcts seen in their sample. The study consisted of 240 subjects; 74 of these subjects had brain infarcts. This subgroup was further divided into 2 groups: Group 1, infarcts in a vascular territory supplying the hippocampal formation; and Group 2, infarcts in other vascular territories. This was done to test the hypothesis that "CA1 dysfunction may occur only when infarcts occur in a vascular territory that also supplies the hippocampal formation, namely the anterior choroidal and posterior choroidal arteries." As we shall elaborate below, the blood supply of the hippocampal formation is complex. 2The anterior choroidal artery (ACha) originates mostly from the internal carotid artery, whereas the posterior choroidal artery (PCha) originates from the proximal posterior cerebral artery.3 Thus, an embolus or thrombus at the origin of these arteries can cause dysfunction of the medial temporal lobe structures. There are also several anastomoses involving the ACha, with branches of middle cerebral artery (MCA), posterior cerebral artery (PCA), and the posterior communicating artery. 4 Analysis of infarct patterns suggests, however, that the hippocampus is infrequently involved by ACha infarction. 5,6 This may be a result of this area being supplied by both the ACha and hippocampal arteries, or the complex anastomoses involved. Moreover, the ACha supplies as far anteriorly as the posterior putamen and posterior limb of the internal capsule and, controversially, as far superiorly as the posterior paraventricular corona radiata region. 5,6 In the paper by Wu et al, the absence of disclosure of the topographic patterns of brain infarcts leads to uncertainty as to whether structures such as the lentiform nucleus or corona radiata were affected in Group 1. Our topographic analysis suggested that these regions are most involved typically in MCA occlusion. 7We also seek clarification about what constituted Group 2 infarcts and whether relevant topographic differences existed between Groups 1 and 2. Such detail would greatly assist our understanding of their findings.We would also like to know why the authors considered the ACha and PCha as most relevant to the hippocampus, given that the posterior cerebral artery and its hippocampal branches are the principal suppliers to this region.2,3 The medial temporal lobe encompasses the hippocampus, entorhinal cortex, subiculum, and dentate gyrus, and these areas all have the same source of ...
