Peroperative assessment in arterial surgery--flow determination or angiography?

Complete data from flow measurement and intraoperative angiography were obtained in 70 femoro-popliteal vein by pass procedures. The results were compared in respect to their predictability of early outcome after arterial reconstruction. A correct prediction was given in 65 of 70 cases (92 per cent) by angiography. The corresponding figure for flowmeter determination was 52 of 70 (74 per cent). Angiography was found to be preferable to flow determination especially when low flow values were registered.

Intraoperative angiography in arterial surgery.

Intraoperative angiography was performed in 136 cases of surgical reconstruction of the aorta, iliac, femoral and carotid arteries. In 39 cases pathological angiograms were found at operation, some of them quite unsupected. The most common pathological finding was non-occluding thrombosis, but intimal lesions caused by vessel clamps and incomplete endarterectomies were not uncommon. Immediate surgical reexploration and revision resulted in a high frequency of open reconstructions at follow-up, which was performed 1--24 months postoperatively. On the other hand, nonrevised reconstructions with pathological angiograms usually failed in the early postoperative period. In cases with normal intraoperative angiograms the result at follow-up was excellent. In addition to electromagnetic flow determination, intraoperative angiography is a most valuable adjunct in the assessment of vascular surgery during operation and should be used more frequently. All pathological findings in the angiograms must be seriously considered and lead to reexploration and revision.

Vagotomy and gallbladder function.

The effect of vagotomy on gallbladder function was investigated in a clinical and experimental study. In the clinical study both the size of the gallbladder and its capacity to respond to cholecystokinin were evaluated radiologically before and after vagotomy. In studies in the rabbit, both the immediate effect of vagotomy on the gallbladder and the effect of varying doses of cholecystokinin on gallbladder pressure were studied before and after vagotomy. In studies in the cat the long-term effect of vagotomy was studied with respect to the histology of the gallbladder and the composition of bile. The clinical investigation showed that vagotomy was followed by a significant increase in the volume of the gallbladder and that the effect of the cholecystokinin on the gallbladder remained unchanged after vagotomy. In experiments in the rabbit it was found that cholecystokinin in a dose of 1 unit/kg body weight exerted a somewhat lesser effect on gallbladder pressure after vagotomy than before, while after vagotomy a dose, approximately four times greater, resulted in a stronger gallbladder response. Further, the experiments showed that the chemical composition of the bile seemed to be altered after vagotomy, while the gallbladder remained histologically essentially unchanged.
