The Lucite Calvarium—A Method for Direct Observation of the Brain

used in the development of the method. Many difficulties were encountered, the outstanding of which were the clouding of the cerebral surfaces due to the deposition of fibrin on the leptomeninges, the obtaining of a secure fit of the plate to prevent leakage of cerebrospinal fluid, and the proper treatment of the skin. The formation of the filmy layer of fibrin over the surface of the brain has been prevented by meticulous hemostasis of the dura and bone and by drainage of the “subdural” space for several days following the second stage of operation.

on the control of bleeding is highly important for a further reason. In it the author describes the use of muscle, bits of living tissue or well solidified blood clots as a valuable aid in arresting surface oozing or bleeding on the dura. Apparently this was the earliest reference in the literature to such a method of hemostasis, although Cushing stated in a footnote that Dr. Lund had reported having seen Horsley demonstrate the use of muscle in the same way the year previously. However, Cushing further remarked, “Since this device for checking bleeding was first

The Use of Products Prepared from Human Fibrinogen and Human Thrombin in Neurosurgery

Fibrin Foams as Hemostatic Agents; Fibrin Films in Repair of Dural Defects and in Prevention of Meningocerebral Adhesions

Franc D. Ingraham and Orville T. Bailey

. Two of the many groups of problems which still await satisfactory solution are those connected with hemostasis and those related to the prevention of meningocerebral adhesions. For progress in each of these directions, new materials are needed to supplement or supplant those now at hand. Substances which may be applicable to both these groups of problems have recently been prepared on a large scale by the Department of Physical Chemistry at the Harvard Medical School by the fractionation of human blood plasma. 2 Of particular interest in the technique of

only to enumerate his introduction of the use of suction in neurosurgical procedures, his employment of the magnet for withdrawing deeply embedded shell fragments, the silver clip for hemostasis, not to mention a host of other less dramatic procedures which together served to convert wartime surgery of the head from a horror into one of the most fruitful and gratifying of all branches of traumatic surgery. Constantly striving for improved methods of hemostasis, he was led, some years after the last war, to introduce electrosurgical methods for ablation of vascular

applied. A favorable position for the injured joint or bone may be an unfavorable one for nerve repair; therefore, before operation is attempted, joint mobilization by all means available should be undertaken. Hemostasis . Careful hemostasis is especially important in peripheral nerve surgery. A wet field with the inevitable swelling that accompanies it is incompatible with consistently good results. It should be unnecessary to state that a tourniquet is seldom necessary or justifiable in operations upon peripheral nerves unless there is an associated lesion of one of

mm. in diameter, was made and one of the larger cerebral veins divided through a small opening in the dura close to the superior longitudinal sinus. Haemostasis was easily secured with a muscle-stamp. The wound was then closed. II. In 2 rabbits the usual decompression was made and the two large cerebral veins in the area were divided both near the longitudinal sinus and also near the lateral border of the decompression. The dura was left intact over the brain except at these points of division, thus preventing the occurrence of herniation. As before

T he prompt and complete control of bleeding with the minimum of injury to living tissue is of first importance in all forms of surgery. Perfect hemostasis is especially difficult in many neurosurgical procedures and the securing of it occupies a considerable portion of the time required by these operations. The various agents in current use for this purpose have been considered elsewhere. 1, 2 A completely satisfactory hemostatic material for neurosurgical procedures should meet several criteria. It should be readily available; it should produce prompt

pulsated freely. Bleeding from the orbital ridge was controlled with bone wax. The right frontal lobe was elevated exposing the cribriform plate where a linear fracture was visualized to the right of the crista galli. The dura was carefully inspected but no defect could be found. A stamp of fascia taken from the temporal region was placed over the site of fracture. Two silver clips were attached to the fascial stamp to mark the location of the plastic repair. After careful hemostasis, sulfanilamide powder was dusted into the wound and closure was carried out in layers

spinous processes and both laminae of one or more vertebrae are removed. It is essential in removing tumors of the spinal cord to have adequate exposure in order to permit complete removal of the tumor and accurate hemostasis. In the case of neurofibromas it is necessary to expose the involved nerve root above and below the tumor so that the entire tumor can be removed and thus recurrence can be avoided. In removing meningiomas it is necessary to resect the meninges widely around the neoplasms to forestall recurrence. The dura mater adjoining the tumor is usually richly
