Pseudoaneurysm: diagnosis with color Doppler ultrasound.

Increasing numbers of interventional radiologic procedures, often with large arterial catheters, have led to increasing total numbers of complications. Pseudoaneurysm is not an infrequent complication. It is often difficult to differentiate pseudoaneurysm clinically from hematoma. In the past, we have used gray scale duplex scanning to aid in this differentiation. We have recently found color Doppler scanning to allow quicker, easier, and more accurate diagnosis. Color Doppler imaging also can often demonstrate the track between the artery and the aneurysm.

Presentation of undiagnosed pheochromocytoma during coronary artery bypass surgery.

Hypertension and tachyarrhythmias arising during an operative procedure are rarely caused by an unsuspected pheochromocytoma. However, when this tumor becomes clinically manifest under general anesthesia during a procedure for an unrelated condition, the mortality is high. An unusual case of a patient who developed episodes of catastrophic hypertension and tachyarrhythmias while undergoing a coronary artery bypass procedure is described. The subject of undiagnosed pheochromocytoma becoming clinically manifest under general anesthesia is discussed with a pertinent review of the literature.

Tricuspid incompetence resulting from retrograde aortic dissection.

This paper presents a 51 year old black female with known hypertension and an acute illness characterized by aortic regurgitation, cerebrovascular insufficiency, renal insufficiency, aortic valvular insufficiency, mediastinal widening and other features characteristic of acute Type I aortic dissection. An unusual feature in this individual is dissection extending into the membranous septum of the heart and into the aorto-atrial space with large hematoma, which partially disrupted the conduction system as well as dislodging the tricuspid septal leaflet in such fashion that major tricuspid regurgitation was present and interfered with termination of cardiopulmonary bypass. This patient presents a very unusual complication of which we wish to inform the readers.

Surgery of left atrial myxomas. Report of eleven cases and review of the literature.

Eleven patients with left atrial myxoma in a ten-year period were reviewed. They ranged from 16 to 69 years old. Eight patients were female. All tumors were located in the left atrium; one patient had multiple tumors. The main clinical presentation was congestive heart failure seen in eight patients. Ten patients had a correct pre-operative diagnosis. Echocardiography confirmed the diagnosis in seven patients, angiocardiography in two and cardiac catheterization in one. All tumors were successfully removed with the aid of cardiopulmonary bypass and using a right atriotomy and trans-septal approach. Two patients underwent concomitant saphenous vein aortocoronary bypass. There were no operative deaths. Excision of the tumor resulted in marked symptomatic improvement. There have been no recurrences. A review of the pertinent literature is presented.

Management of vena caval injuries: the Vietnam vascular registry review.

Injuries to major vessels during combat have been associated with high mortality and morbidity, despite optimal triage and management. Eighty-two vena caval injuries from the Vietnam Vascular Registry (VVR) series have been studied. The nature of the wounding agents, location of wounds, and associated injuries have been documented and are contrasted with those of recent civilian series. Seventy-eight abdominal vena caval injuries were associated with mortality in 18 (23%), in whom 56 underwent repair of the injury and 15 had ligation of the inferior vena cava. This is the largest series reported of war-related vena caval injuries, and therapeutic alternatives and general recommendations derived from this review are presented.
