    Rapid Microvascular Repair Using Plastic Adhesive
    Ovid Technologies (Wolters Kluwer Health) ; 1972
    In:  Stroke Vol. 3, No. 1 ( 1972-01), p. 34-40

    In: Stroke, Ovid Technologies (Wolters Kluwer Health), Vol. 3, No. 1 ( 1972-01), p. 34-40
    Abstract: Simple longitudinal arteriotomy was carried out in rabbits to assess the use of a rapid-setting tissue adhesive in shortening the time necessary to carry out microvascular repair. The vessels studied varied from 0.8 to 1.5 mm in diameter and repair was carried out using microsurgical dissection. It was found that the use of the tissue adhesive in conjunction with three sutures would bring about satisfactory repair of the arteriotomy for shortening the time of repair by at least 50%. Toxic reactions or other complications common to micro-anastomosis of small vessels were not encountered with any greater frequency than in controls.

    Pathological characteristics of experimental thermal lesions : Comparison of induction heating and radiofrequency electrocoagulation
    Journal of Neurosurgery Publishing Group (JNSPG) ; 1972
    In:  Journal of Neurosurgery Vol. 37, No. 4 ( 1972-10), p. 418-422

    In: Journal of Neurosurgery, Journal of Neurosurgery Publishing Group (JNSPG), Vol. 37, No. 4 ( 1972-10), p. 418-422
    Abstract: ✓ Experimental thermal lesions were produced in the liver and brain of rats and rabbits by induction-heating, radiofrequency electrocoagulation, and surface-heating. Pathological examination revealed similar destructive changes from all three methods and demonstrated that lesions were essentially similar in histological character. The safety of different techniques appears to be more related to technical problems in the generation of the lesions than to the physical characteristics of the lesions themselves.

    Transorbital pituitary stalk section in primates
    Journal of Neurosurgery Publishing Group (JNSPG) ; 1972
    In:  Journal of Neurosurgery Vol. 37, No. 5 ( 1972-11), p. 601-605

    In: Journal of Neurosurgery, Journal of Neurosurgery Publishing Group (JNSPG), Vol. 37, No. 5 ( 1972-11), p. 601-605
    Abstract: ✓ Pituitary stalk section through the orbit by microsurgical technique is described in eight monkeys. The use of the microscope and the approach through the optic foramen minimize incidental injury. Under these circumstances experiments designed to study neuroendocrine relationships may be carried out free of errors introduced by damage to the temporal lobe or hypothalamus. Plasma cortisol drops to very low levels, but still support life. Growth hormone output is negligible.

    A Model for Experimental Cerebral Arterial Spasm
    Ovid Technologies (Wolters Kluwer Health) ; 1972
    In:  Stroke Vol. 3, No. 1 ( 1972-01), p. 49-56
    Details
    In: Stroke, Ovid Technologies (Wolters Kluwer Health), Vol. 3, No. 1 ( 1972-01), p. 49-56
    Abstract: Vasospasm of the basilar artery of the dog was induced by subarachnoid injection of arterial blood through the cisterna magna. Cerebral angiography was employed to evaluate quantitative assessment of the spasm. Chronic vasospasm was successfully induced in 100% of surviving dogs. Biphasic vasoconstriction was observed. The acute phase occurred within 30 minutes after the blood injection and tended to abate. Chronic spasm was demonstrated on the second day's angiograms and persisted to the seventh day in some cases. Etiology of the chronic spasm using this model is now under investigation. Vasospasm was not due to alterations in blood gas concentration or blood pressure, to increased CSF pressure or to injury from contrast medium or direct trauma. The primacy of blood as the offending agent is strongly suggested.

    Papaverine Hydrochloride and Experimental Hemorrhagic Cerebral Arterial Spasm

    In: Stroke, Ovid Technologies (Wolters Kluwer Health), Vol. 3, No. 1 ( 1972-01), p. 27-33
    Abstract: Chronic hemorrhagic spasm of the basilar artery was produced in beagle dogs by introducing blood into the cisterna magna. Spasm was evaluated by means of vertebral angiography. Papaverine hydrochloride was administered intravenously, intracisternally as well as intra-arterially. The intracisternal route was the more effective in combating spasm but the effect was transitory. The results suggest that the treatment of spasm by chemical means in subarachnoid hemorrhage using agents currently available would require continuous topical application.
