✓ A new technique of direct retraction of an aneurysm or major arteries using tapered brain retractors is introduced. The system requires three separate instruments: 1) a tapered brain retractor, 2) a flexible self-retaining retractor of light weight, and 3) a multipurpose head frame.

✓ A case of bitemporal hemianopsia in a 68-year-old woman is reported. Surgical exploration revealed bilateral compression of the optic nerves by the arteriosclerotic internal carotid arteries. Microsurgical decompression with unroofing of the optic canals resulted in prompt recovery of the visual fields.

✓ A new hemostatic method has been devised that uses a metal shield for treating accidentally injured major cerebral arteries. The metal shield is made of stainless steel, and has a small plate on its outer surface that allows it to be held in a regular aneurysm clip holder. Three different sizes of shield are available. The metal shield is applied to an injured artery with Oxycel and Biobond and held for a few minutes. Bleeding stops instantaneously. This is a simple and effective hemostatic method for an injured artery of small size. Experimental results and clinical application of this method are described.
