The control of bleeding after cardiopulmonary bypass by the intrapericardial instillation of fresh frozen plasma and platelets with microfibrillar collagen.

A technique of, and the results obtained with, the intraoperative and postoperative intrapericardial instillation of microfibrillar collagen and fresh frozen plasma and platelet mixture are presented. Intraoperatively, the mixture was instilled into the exposed mediastinum in the course of open-heart operations in 31 patients in whom diffuse oozing of blood persisted following the termination of cardiopulmonary bypass and the neutralization of circulating heparin. Immediate clot formation and decrease of blood loss were observed in all instances. This method was also found effective in 9 of 20 patients who had continuing blood loss during the hours following open-heart surgery and in whom the mixture was instilled through the mediastinal drainage tubes.

The value of thermography in the early diagnosis of postoperative sternal wound infections.

Peristernal skin temperatures were recorded postoperatively by infrared thermography in 150 patients. Persistent elevation of peristernal skin temperature during the 3rd and 4th post-operative week was found in 5 patients, all of whom developed sternal wound infection. A further group of 18 patients, all suspected to have occult wound infection, showed persistent temperature elevation in 7 patients, 6 of these patients were proven later to have manifest infection and needed treatment. Close thermographic scruting of the incision in patients with suspected but not proven infection appears to be useful in deleting early stages of deep seated infections.

Long-term observations on a crimped Dacron aortic bypass graft in the growing child.

Nineteen years of clinical and angiographic observations are presented on a patient with congenital stricture of the upper abdominal aorta who underwent thoracic-to-abdominal aorta bypass grafting using a woven crimped Dacron vascular prosthesis. These observations indicate that if such a prosthesis is properly applied, i.e., attached in a proper angle and is not stretched as it is usually done in the adult, then it will be capable of gradual "lengthening" through the years and thus adapt to the needs of a growing child.

Diffuse dilatation of autogenous saphenous vein grafts used to replace the renal and superior mesenteric arteries. A case report.

Of the many different materials used to replace diseased arteries, autogenous saphenous vein grafts are among the most favored. This view is also explicitly expressed regarding patients who suffer from occlusive arterial disease of the abdominal viscera, particularly the renal vessels. There is, however, recent information which suggests that for reasons unknown saphenous vein grafts in the renal position are likely to be subject to both diffuse and aneurysmatic dilatation, a complication seen only seldom in the femoral and practically never in the coronary position. The purpose of this paper is to present the case of a young woman with fibromuscular stenosis of both her abdominal renal and the mesenteric arteries whose condition was surgically corrected using autogenous vein grafts. Despite the fact that at the time of her surgery her saphenous vein appeared to be both macroscopically and microscopically intact and postoperatively her blood pressure returned to normal, she developed diffuse, aneurysmatic dilatation of all of her vein grafts.

Biochemical termination of sustained fibrillation occurring after artificially induced ischemic arrest.

A method of biochemical termination of persistent ventricular fibrillation is presented. The technique consists of re-cross-clamping the ascending aorta while the patient is still on cardiopulmonary bypass, infusing 37 degrees C buffered potassium cardioplegic solution into the coronary system, and, after having achieved flaccid standstill, pacing the heart by the ventricular mode.

Massive chest trauma due to impalement.

It is concluded in cases of thoracic impalement after arrival to the hospital the chances of survival are high because the probability is dominant that organ injury is most probably limited to severe contusion of the lung and that the cardiovascular system is largely spared by the penetrating object. The case histories of two patients surviving massive thoracic impalement are presented. Factors influencing initial survival and principles of surgical management are discussed.

Dye-enhanced fluoroscopy-directed catheter embolectomy.

A method is presented that uses a double-lumen balloon catheter to perform embolectomy under contrast-enhanced fluoroscopy control. The technique has the advantage of localization of the thrombi before removal; it permits the individual arterial branches to be entered during embolectomy and allows confirmation of the patency of the arterial tree after completion of the embolectomy.

A new method to treat fusiform aneurysms of the ascending aorta associated with aortic valve disease: an alternative to radical resection.

A new method designed to deal with special forms of fusiform aneurysms of the ascending aorta associated with aortic valve disease is presented. The procedure consists of replacing the aortic valve, decreasing the aortic diameter by excision of an oval segment, placing a well-tailored Dacron vascular graft around the ascending aorta, and anchoring it with previously placed sutures driven through the sewing ring of the valve prosthesis through the aortic wall. The technique has been applied in 6 patients with postoperative observation ranging from six weeks to two and a half years. Technically the operation was carried out without difficulty, and all the patients are doing well.

An epitaph for cavopulmonary anastomosis.

Cavopulmonary anastomosis was developed by several surgical groups working independently and probably unaware of each other. In a most unusual way, the primary discoveries were left unnoticed, the initial trials were not followed up, and the first clinical successes were generally disregarded. After that, however, there was intensive experimental and clinical activity during which the physiology of this new operation was studied intensively and it was applied in a large number of clinical cases. After the development of more radical procedures, the operation gradually fell into disuse. This essay discusses the place of the cavopulmonary shunt in surgical history.

Myocardial protection during coronary surgery. Getting the maximum advantage of both cardioplegia and hypothermia.

The author presents a specially timed protocol of a combination of cold cardioplegic arrest and deep total body hypothermia designed to include the best features and to eliminate some of the principal short-comings of these 2 commonly used methods of myocardial preservation. According to this protocol, the operations were divided into 3 periods: (1) About half the number of the peripheral anastomoses are done in the first period while the body is cooled to 20 degrees C and the during which the heart is in cold ischemic cardioplegic arrest. (2) Most or all proximal anastomoses are done in the second period during which body temperature is kept at 20 degrees C and the heart is in a per vias naturales perfused cold arrest. (3) During the third period, the remaining anastomoses are completed while the heart is again in cold ischemic cardioplegic arrest and the body is rewarmed. This method was used in excess of 100 myocardial revascularization procedures with satisfactory clinical results.
