Uchida tubal sterilization

The methods which seek to close the tubes by tissue necrosis may be responsible for subsequent pathologic disorders. These sequelae often explain postoperative repeat uterine pregnancy, ectopic gestation, and other serious complications. In addition to Uchida sterilization, the Uchida fimbriectomy is recommended for use in the immediate postpartum period and at cesarean section because of its many advantages.

New arteriographic and surgical techniques for vertebral arteriopathies

Vertebral arterial insufficiency syndromes are being diagnosed with greater frequency, and would appear to be at least as common as carotid disease in causing cerebrovascular insufficiency. Carotid lesions are nearly always arteriosclerotic, but vertebral obstructions are caused at least as frequently by nonarteriosclerotic lesions, including tortuosity with kink and external bands, slings, bony compression, and congenital aberrations.

A method of cerebral arteriography has been standardized and a new radiographic sign of comparative opacification times of the intracranial carotid and basilar arteries has been tested as a pathognomonic sign of vertebral-basilar arterial insufficiency.

The concept of the innominate-subclavian-vertebral complex as a single surgical geometric unit has allowed the development of a graded surgical approach of arteriolysis, endarterectomy, and resection and anastomosis in managing 97% of obstructive vertebral arteriopathies.

A new surgical operation of distal subclavian resection and anastomosis to correct vertebral and/or subclavian arterial tortuosity with kinking has proven helpful in ablating symptoms of vertebral-basilar arterial insufficiency.
