Sixty-four patients with clinical diagnosis of cerebral thrombosis, subarachnoid hemorrhage, cerebral vascular malformation, and carotid arterial lesion, submitted to both caroted Doppler ultrasonographic detection (CDUD) and arteriography were analysed ( a total of 69 time-sides of carotid arteriography and 5 cases bilaterally).In contrast to arteriography the diagnosis was accurately establiahed by CDUD in 37 patients, including 28 normal carotids, 6 extracranial internal carotid occlusions, 2...

Sixty-four patients with clinical diagnosis of cerebral thrombosis, subarachnoid hemorrhage, cerebral vascular malformation, and carotid arterial lesion, submitted to both caroted Doppler ultrasonographic detection (CDUD) and arteriography were analysed ( a total of 69 time-sides of carotid arteriography and 5 cases bilaterally).In contrast to arteriography the diagnosis was accurately establiahed by CDUD in 37 patients, including 28 normal carotids, 6 extracranial internal carotid occlusions, 2 internal carotids narrowing by more than 50%, and 1 external carotid arteriovenous fistula. There were no false positive and no false negative in detection of internal carotid constriction by more than 50%.In cases of carotid arteries narrowing by less than 50%. dodichocarotid with minimal kinking and intracranial arterial obstructions, CDUD is of no use in diagnostic approach.

本文报道颈动脉多普勒超声检查与血管造影对比资料64例69侧次的结果。病例包括临床诊断为脑血栓形成、蛛网膜下腔出血和颈动脉病变者。以多普勒检查波形、波幅差率、舒末差率、颞浅动脉压迫试验及阻力指数作为观察指标,取得有关正常值。本法无损伤、迅速;对预内动脉狭窄超过50%以上、颈外动脉动静脉瘘、引起颅内血流增加的颅内病变的诊断有较大可靠性。

Nine cases were reported.The so-called “cerebrovascular disorders” misdiagnosedincluded 2 cases of SSAH,2 cases of cerebral vascular malformation,one cerebralhemorrhage,2 cases of cerebral infarction,one cerebellar hemorrhage and one par-kinsonian syndrome.The 9 pathological findings included 7 brain tumors,one cerebral abscess andone bilateral chronic subdural hematoma,while 7 case-histories of which were pre-sented in this article.Extrapyramidal symptoms have been known as a rare complication in chronicsubdural hematoma,however,the author has described a parkinsonian syndrome sub-sequent to bilateral subdural hematoma.The clinical features of parkinsonian syndrome might be caused by mechanicalcompression on the basal ganglion nuclei directly from the hematoma,or indirectlydue to distorsion or displacement of deep brain structures,or due to brain hernia-tion through the tentorial notch.Transient circulatory disturbances of basal ganglionstructures might be caused by the displacement of or compression on the anteriorchoroidal or posterior cerebral arteries.

我们治疗了9例被误诊为各种不同类型脑血管病的颅内占位性病变。本文代表性地报告其中7例,并结合国内外文献对其发生机制和误诊原因加以分析和探讨。在本文报告的病例中,有1例较为少见的双侧慢性硬膜下血肿,曾被误诊为震颤麻痹,我们参考近年国外文献报告,论述了产生的机制可能与基底节的移位或可能影响大脑后动脉和脉络膜前动脉的血循环而出现锥外系症状有关。

Cerebroangiographic and CT findings in 45 cases of cerebral microvascular malformations were analysed. Only 71.1% cases were shown by angiography and more than half lesions were supplied by a single artery (62.5%) and some of the arteries were dilatted the veins draining the malformations showed only filling in 40.6%. According to hemodynamics of cerebral vascular malformations we divided them into two types. Most of the microvascular malformations were of the lower blood flow and higher resistence...

Cerebroangiographic and CT findings in 45 cases of cerebral microvascular malformations were analysed. Only 71.1% cases were shown by angiography and more than half lesions were supplied by a single artery (62.5%) and some of the arteries were dilatted the veins draining the malformations showed only filling in 40.6%. According to hemodynamics of cerebral vascular malformations we divided them into two types. Most of the microvascular malformations were of the lower blood flow and higher resistence type. Most of the large vascular malformations were of the higher blood flow and lower resistence type. Miscellaneous findings were hematoma (6 cases), nodular mixed density (3 cases) and hypodensty (3 cases). 3 cases showed nodular enhancement. The characteristics of the images and their pathologic basis were discussed correlation between the operation and pathology findings was made. The mechanism of hemorrhage were discussed.

本文分析了45例经手术证实的脑微血管畸形病例的脑血管造影及CT扫描结果。脑血管造影对脑微血管畸形显示率为71.1%。畸形多为单根动脉供血(62.5%),且供血动脉增粗少见;引流静脉早现率较低(40.6%)。根据脑血管畸形血液动力学可分为高血流量低阻力型和低血流量高阻力型,脑微血管畸形多属后者。CT扫描脑内血肿6例,结节状、絮状混染密度影3例,低密度影3例、增强扫描仅3例见结节状强化。本文还对脑微血管畸形影像学特征、病理基础及破裂出血原因进行了探讨。
