| Popis: | STUDY OBJECTIVE - The aim of the study was to develop a new procedure to produce abdominal aortocaval shunts in the rat without vascular microsurgery. PROCEDURE - The inferior vena cava and abdominal aorta were exposed by laparotomy. The aorta was punctured caudal to the left renal artery with an 18 gauge disposable needle which was advanced into the vessel, perforating the adjacent wall between aorta and vena cava and penetrating the latter. A bulldog vascular clamp was placed across the aorta cephalic to the puncture, the needle was withdrawn, and the aortic puncture point was sealed with a drop of cyanoacrylate glue. The clamp was removed 30 s later. Patency of the shunt was verified visually by swelling of the vena cava and admixture of arterial and venous blood. No local haemorrhages were seen. The laporatomy was then closed. The procedure takes less than 10 min. RESULTS - Of 11 rats which received this procedure, only one died within 24 h. All the other animals were killed 4 weeks after operation. Nine of these 10 animals had developed cardiac hypertrophy of about the same magnitude. There were no changes in sham operated controls. CONCLUSIONS - This is a reproducible, simple and rapid method of developing high output heart failure and cardiac hypertrophy in the rat which could be useful in many laboratories. |
