摘要:

&NA;The authors discuss 21 cases of large or surgically inaccessible internal carotid artery aneurysms treated with gradual occlusion of the cervical portion of the internal carotid artery. Eighty‐five per cent of the patients experienced relief or marked improvement of their symptoms after treatment. Two early cases developed postligation ischemic deficits that partially resolved. After the introduction of expansion of circulating blood volume and induced hypertension as adjuncts to graded carotid occlusion, no ischemic complications occurred.

摘要:

&NA;To evaluate the risk of definitive intracranial microsurgical aneurysm obliteration as a function of the timing of the operative intervention, we retrospectively reviewed 106 consecutive patients in good clinical condition who underwent such surgery. The patients who were operated upon within the first 8 days of their most recent subarachnoid hemorrhage formed the “early” group; the patients operated upon between the 9th and 31st day were considered to have undergone “late” surgery. On the basis of their clinical outcome the patients were allocated to one of four outcome categories (“good,” “fair,” “poor,” “death”) both at the time of their hospital discharge and at their most recent clinical re‐evaluation, a minimum of 6 months after discharge from the hospital. There was no significant difference in the operative mortality in each group (early surgery, 5%; late surgery, 4%); additionally, no significant difference was noted in the incidence of either intraoperative complications or postoperative morbidity. A suggestive but statistically insignificant increase in the incidence of postoperative cerebral ischemic events was seen in the “early” surgery group (8% vs. 4% for the “late” surgery group). The potential significance of these findings for the timing of intracranial aneurysm surgery is discussed.

摘要:

&NA;Cervical radiculopathy unaccompanied by pain or sensory disorder but manifested only by paresis, atrophy, fasciculation, and reflex loss is unusual. Three such cases are presented. Considerable diagnostic difficulty may arise in distinguishing patients presenting with these features from those who have primary motor neuron disease. Two additional case reports demonstrate that this distinction is not always possible. Diagnosis, management, and prognosis are discussed. Differentiation between motor neuron disease and spondylosis will avert needless surgery in the former group and will result in beneficial, sometimes curative surgery in the latter group.

摘要:

&NA;Four cases of acute hyperesthesia after spinal trauma are presented. An attempt is made to characterize the natural history of this syndrome. In the three cases with truncal sensory aberration, hyperesthetic zones developed only anteriorly. All four patients demonstrated spontaneous relief of pain within 2 weeks after injury. The pain was modified by transcutaneous stimulation in one case and byl‐dopa in another case. It is suggested that the “lesion” responsible for the hyperesthetic response is partial damage to dorsal root fibers at a point medial to the dorsal root ganglion.

摘要:

&NA;A flexible ventriculofiberscope was used to diagnose intraventricular pathological conditions in eight adult hydrocephalic patients. In each case the entire procedure was recorded on videotape for documentation, review, and teaching. Four representative cases are presented to illustrate the use and value of this technique.

摘要:

&NA;Two hundred eleven adult scapulae were examined and quantitative data pertaining to the dimensions of the suprascapular notch were obtained. Six types of suprascapular notch were observed. Transitions tended to occur between Types II, III, and IV. A classification function was developed utilizing the measured values of the dimensions of the suprascapular notch, which might help in assigning the scapulae to these transitional types. Dissections of the suprascapular area were performed in 15 cadavers. Static and dynamic relationships of the suprascapular nerve to the suprascapular foramen were examined.

摘要:

&NA;The suprascapular ligament seems to serve no defined function in the human. A comparative study was undertaken to elucidate its function. The suprascapular region was dissected in species representing seven existing primate families and six subprimate families. A striking dichotomy of pattern was observed. In the New World primates, the suprascapular ligament appeared to be continuous with the coracoclavicular ligament; the former merely served to increase the area of bony attachment of the coracoclavicular ligament. In the Old World monkeys and subprimate mammals, the suprascapular ligament was entirely absent. The human anatomy was comparable to that found in the New World primates. This dichotomy of pattern seems to be related to the function of the upper extremity in the different classes of mammals.

摘要:

&NA;Selected commercially designated temporary clips (Acland, Biemer, Kleinert‐Kutz, Variangle, and Yasargil) were applied for 1 hour to rat common carotid arteries. Scanning electron and light microscopic studies revealed varying degrees of endothelial damage. The authors believe that further improvements are needed in the design of temporary clips.

摘要:

&NA;The extent of a brain tumor or abscess in the cerebral hemispheres can be easily projected onto the scalp by using small radioactive markers. A positive uptake by the lesion is seen on the persistence scope of the nuclear camera and can be delineated by scalp markers to define the limits of future craniotomy. This technique has been used for six tumor operations and has successfully reduced the size of the craniotomy and brain incision, as well as increasing the accuracy of localizing the tumor.
