Femoropopliteal bypass grafting: predictive value of preoperative angiography.

Our experience with femoropopliteal grafting was reviewed to determine whether quantitative grading of the preoperative angiogram could be correlated with the outcome of the grafting procedure. The series consisted of 53 bypass grafts in 50 patients. The quantitative grading of the preoperative arteriogram correlated with the graft closure rate during the follow-up period of 48 months. The group with the most advanced arterial occlusive disease on angiography had a 32 per cent failure rate, while those with the least severe disease had a 6.7 per cent failure rate. The intermediate group had a 16.7 per cent closure rate. Using linear regression analysis, the data indicated a correlation between the time of graft failure in the first 18 months and the angiographic grade (p less than 0.01).

Radionuclide blood flow studies before and after gelfoam embolization of intracranial meningiomas.

Radionuclide blood flow studies were employed to evaluate the success or failure of preoperative Gelfoam embolization in two patients with intracranial meningiomas. In both cases, the initial radionuclide blood flow study showed tumor visualization during the arterial phase. Immediately following the embolization procedure, the radionuclide blood flow study showed no visualization of the meningioma during the arterial phase, indicating a successful embolization procedure in preparation for removal of the tumor in a relatively bloodless field.

Radionuclide pulmonary arteriography.

Radionuclide pulmonary arteriography offers a unique method for visualizing the main pulmonary artery and its major branches. Since the radioactive particles that are injected intravenously become lodged in the pulmonary capillaries and pre-capillary arterioles, there is no interference from the systemic circulation. Normally, the main pulmonary artery is visualized for no longer than 4 or 6 seconds; prolongation of the duration of visualization may be indicative of, for example, pulmonary hypertension and pulmonary embolism. The patency of the left and right pulmonary arteries may be determined and sites of occlusion identified.

Pleural effusion.

Pleural effusion unassociated with other radiologic evidence of disease is a challenging diagnostic problem. With small effusion, only silhouetting of the diaphragm may be noted. A lateral decubitus view will often be helpful. After a careful history, physical examination and selected hematologic studies, diagnostic thoracentesis is indicated. The following determinations on the fluid may be useful: color, character, protein, lactic dehydrogenase (LDH), glucose, amylase and cytology. Pleural biopsy may be helpful with tuberculosis and malignancy.
