Case Reports
Intraoperative fiberoptic angioscopy to evaluate the completeness of pulmonary embolectomy.
Intraoperative angioscopy was performed in three patients who underwent pulmonary embolectomy for massive pulmonary embolism. Angioscopy followed conventional techniques such as extracting the clot by a gallstone forceps, using a Fogarty catheter in the pulmonary tree or squeezing of the lungs. The rationale for angioscopy was to assess the result of these usual "blind" techniques. ⋯ Our initial experience suggests that intraoperative angioscopy appears to be useful in the detection of residual thrombus material, especially in the asanguinous, arrested heart. The small size of the angioscope allows easily access to the secondary, and up to the tertiary pulmonary branches. Clots can be visualized and extracted under direct visual control.

Chylous ascites following abdominal aortic aneurysmectomy: surgical management with a peritoneovenous shunt.
The development of chylous ascites after emergency repair of a ruptured abdominal aortic aneurysm (AAA) is an extremely rare complication with potentially grave mechanical, nutritional, and immunologic consequences. A 54-year-old man with recurrent, symptomatic chylous ascites ultimately required insertion of a peritoneovenous shunt after non-operative measures failed to provide relief. This is the fourth reported case of chylous ascites following ruptured AAA and only the second treated by peritoneovenous shunt placement.

Bullet embolism is a rare complication of vascular trauma. During the last ten years we have treated six patients with bullet embolism. Three patients had inferior vena caval injuries with embolizations of the bullets to the heart or pulmonary arteries. ⋯ Emboli in the distal pulmonary artery branches were left undisturbed in two patients. All six patients survived without any complications. A 14-year review of the literature is presented in order to emphasize some important features of this rare pathology.

Heart surgery is generally regarded as having begun on September 10, 1896 when Ludwig Rehn sutured a myocardial laceration successfully. There are valid reasons, however, to believe that cardiac surgery had its origin nearly a century earlier with the operative drainage of the pericardium by the little known Spanish surgeon, Francisco Romero, and highly regarded Baron Dominique Jean Larrey. This procedure entailed making a thoracic incision and opening and draining the pericardium. ⋯ The pericardium is part of the heart; its epicardium continues as the serosal layer of the fibrous pericardium; the pericardium is fused to the heart's base and great vessels; all books on heart surgery include pericardial operations. When Romero first operated is unknown, but it antedated 1814 when his work was presented in Paris; Larrey's operation was performed in 1810. These contributions are presented, and their priority with regard to the later initial efforts to suture myocardial laceration is reviewed briefly.

The Authors report 5 cases of cardiac injury after blunt chest trauma: (a) one right atrial disruption with acute tamponade treated successfully; (b) two left ventricular perforations with rib fractures: one patient was exsanguinated and died, the other one presented a late subacute cardiac tamponade with successful operative repair; (c) one isolated traumatic tricuspid insufficiency which was well tolerated; (d) one atrio-inferior caval disruption with acute tamponade. Cardiac damage secondary to nonpenetrating chest trauma is uncommon but with the present modes of high speed transportation they are occurring with increasing frequency; correct management of cardiac ruptures depends upon rapid recognition of the injury and expeditious surgical repair. The occurrence of tricuspid valvular lesions alone as a result of nonpenetrating trauma is not common. Echocardiographic examination after blunt chest trauma is a useful diagnosis procedure.
