Scanning electron microscopy of nerve sheath neoplasms.

Neurofibromas and schwannomas were clearly differentiable by scanning electron microscopy of thin microscopic sections. Neurofibromas exhibited ordered laminations of collagen with scattered fibroblast-like cells interspersed. Schwannomas contained proliferations of smooth tube-forming cells. These neoplastic characteristics were compared with cellular characteristics of normal nerve sheaths to determine the cell of origin in each neoplasm.

A technique for closure of the lesser curvature of the stomach used in the von Eiselberg-Hofmeister reconstruction after subtotal gastrectomy.

A technique for closing the lesser curvature of the stomach after subtotal gastrectomy has been used in 847 subtotal gastrectomies. In this group, one patient had transient postoperative bleeding and none had anastomotic leakage. The technique is recommended as a simple method of obtaining a secure and hemostatic closure which can be accomplished rapidly and which does not require the use of special instruments or material.

Aortocaval fistula detection using a Swan-Ganz catheter.

The placement of a Swan-Ganz catheter into the abdominal vena cava by the femoral route is recommended for all patients presenting with severe congestive heart failure and an abdominal aortic aneurysm. If an aortocaval fistula exists, its presence can be determined immediately by noting increased vena caval pressure and higher than normal oxygen content. Immediate recognition of this condition is essential. Fluid overloading is avoided, immediate surgical treatment is instituted and the defect is closed. Minimal manipulation is done in an effort to prevent pulmonary embolization. If the results of catheter studies show no evidence of an aortocaval communication, it may be advisable to make an effort to correct the congestive heart failure before surgically correcting the aneurysm.

Special problems associated with abdominal aneurysmectomy in spinal cord injury patients.

There were 8 patients with spinal cord injury in the last 100 consecutive patients with abdominal aortic aneurysm resected at the Long Beach Veterans Administration Hospital. Emphasis is placed upon the problems in management not found in individuals without spinal cord injury. A successful outcome is dependent upon: (a) aggressive control of foci of infection, (b) early diagnosis and planned surgical intervention, (c) continuous intraoperative arterial and central venous pressure monitoring and (d) alertness to the prevention of postoperative complications, with emphasis upon careful tracheal toilet and anticipation of delayed wound healing.
