The middle cerebral artery and its branches were examined in 110 adult and child brains under 6-40 magnification. The following results were obtained.The main stem of the left middle cerebral artery was larger and longer than that of the right. The anomalies of the middle cerebral artery occurred less frequently than anomalies of the other major intracranial arteries. In this study, only one case of duplication of the middle cerebral artery was encountered.The patterns of the branching of the middle cerebral artery could be classified into 3 types. Double trunk type was the most common one, occurred in 76.37±2.86%. Single trunk type and triple trunk type occurred in 12.73±2.24% and 10.90±2.10% respectively. The latter two types could be further classified into some subtypes.The cortical branches of the middle cerebral artery consisted of frontalis orbitalis, precentralis, centralis, postcentralis, parietalis inferior, temporalis polaris, temporalis anterior, temporalis media, temporalis posterior and gyri angularis arteries. Each of these branches were usually 1~2 in number, and could originate independently or in common trunk with other branches. The average outer diameter of these branches were larger than 1.0 mm, except the temporalis polaris artery.The central branches of the middle cerebral artery consisted of medial perforating arteries and lateral perforating arteries. The medial perforating arteries were short, small, and 2-3 in number. They usually originated from the main stem of the middle cerebral artery at right angle, and then ascended to penetrate the brain through the anterior perforated substance. The lateral perforating arteries were 2~3 in number too, but they were larger than the medial perforating arteries. They originated at an acute angle from the main stem of the middle cerebral artery, or from a point of division of the middle cerebral artery, and from one of the cortical branches of the middle cerebral artery. Immediately after arising from the middle cerebral artery, they always passed medially and upward in a recurrent direction to the parent vessel after which they turned upward and laterally to penetrate the anterior perforating substance.The clinical significances of the middle cerebral artery and its branches were briefly discussed.

在解剖显微镜下放大6~40倍观察了110例成人和儿童脑的大脑中动脉及其分支。大脑中动脉主干左侧较右侧稍粗而长,其变异少见,仅见到1例左侧双干。大脑中动脉的分支形式可分三型:主干型,计28侧,占12.73±2.24%;双干型,计168侧,占76.37±2.86%;三干型,计24侧,占10.90±2.10%。双干型和三干型又可分为若干亚型。大脑中动脉各皮质支通常为1~2支,可单独发起或与邻近支合干。除颞极动脉细小外,其余支在大脑外侧裂处成人的平均外径均超过1毫米,角回动脉和颞后动脉较粗,分别为1.51±0.03毫米和1.46±0.03毫米。内侧穿动脉多为2~3支,较细,绝大多数起源于大脑中动脉主干(占96.80±0.64%),少数发自大脑中动脉分叉处、上干和皮质支。多数呈直角发起,直接穿入前穿质。外侧穿动脉多数也是2~3支,较内侧穿动脉粗大。同一个标本上血管的粗度比较一致,故粗大的“Charcot大脑出血动脉”在本文未获证实。外侧穿动脉起源于大脑中动脉主干和分叉处者超过半数,在手术处理大脑中动脉瘤时应予注意,以免误伤。外侧穿动脉通常呈锐角发起,与主干逆行,先向内上方,再弯向外上方行达前穿质。

119 cases of cerebral embolism constituting for 4.5% of the total number of stroke are reported. The data obtained suggest that in a lot of patients the stroke resulted from rheumatic heart disease had mostly(79.8%) an acute onset. The mechanism of stepwise stroke occuring in 3 patients is discussed. Examination of the CSF was performed in 61 patients. RBC in CSF (range 26-8000/mm3) in 21 patients indicated that they originated from hemorrhagic infarcts. 13 patients 'underwent cerebral angiography, and occlusion of intracranial artery, presence of intracranial mass and vertebro-arterial spasm were respectively found in 8,3 and 1 cases, and among them only 1 case showed recanalization. Therefore,cerebral angipgraphy sometimes may be useful method in differential between cerebral embolism and cerebral thrombosis.

Fire hundred and twenty cases of operated intracranial aneurysm were analized about their location, shape, size, coexistent diseases, vascular spasm and bleeding. Carotid-posterior communicating artery aneurysm made up 53.6% whereas anterior communicating artery aneurysm, 16%. The most common shape was saccular type (64.6%) and the next, calabash-like (28.6%). The aneurysm with a local bulging is more prone to bleed. Ordinary aneurysms which are less than 15mm in size comprised 76% of all cases and were more probable to bleed than larger ones. The secondary hemorrhage might occur at any time after the first attack, the shortest interval being one day and the longest 18 years, but 40.55% occured 14 days after the primary hemorrhage. Vessel spasm most commonly appeared 6 to 15 days after the first attack and were confirmed by angiography in 30.71% of the cases. 64.96% of spasm are onthe parent vessel proximal to the aneurysm.A straight linear fronto-temperal incision with a 4cm bone window is sufficient to deal with most aneurysms of the circle of Willis e. g. anterior com., posterior com., middle cerebral and basilar aneurysms, especially useful in the case of multi-aneurysm. The most important step is to expose the pedicle of the aneurysm by way of sharp dissection that would reduce bleeding to its minimum. Only when the pedicle has been clipped the other operation can be taken. For trapping a giant aneurysm on a major artery an extracranial and intracranial artery anastomosis was performed as a preliminary precedure which proved effective to pervent neurological disorders. Copper wire was induced successively into twe giant aneurysms, another giant aneurysm of the basilar artery was clipped using an opposite side approach and the patient recovered smoothly from her previous neurological deficits.

本文分析了手术治疗的520例颅内动脉瘤的部位、形态、大小,并存疾患、动脉痉挛及出血情况。颈内一后交通支动脉瘤占53.6%,前交通支动脉瘤占16%。动脉瘤的形态以球形最多;其次是葫芦形。动脉瘤表面有局部膨出者最易出血。76%的动脉瘤大小为5~14mm,这种普通动脉瘤比大型及巨型的容易出血。第1次出血后任何时间皆有发生第2次出血的可能,46.55%的病人第2次出血是在第1次出血14天之后发生。动脉瘤出血后血管造影发现30.71%出现动脉痉挛,以出血后第6~15天最多,占同期造影的47.01%;64.96%的动脉痉挛发生于载瘤动脉近端。额颞直线切口及4cm~2骨窗可直接处理Willis氏动脉环的大多数动脉瘤,特别对其多发动脉瘤很有用。对重要动脉的巨型动脉瘤孤立前,行颅内-外动脉吻合。一例巨型基底动脉瘤由对侧夹闭瘤蒂成功。
