1. Hemodynamic evaluation of dogs submitted to total circulatory arrest using "Inflow Occlusion" technique for different periods of time / Avaliação hemodinâmica de cães submetidos à parada circulatória total através da técnica do "Inflow Occlusion" por diferentes períodos de tempo
Because of difficulties related to extracorporeal circulation in Veterinary Medicine, more interest occurred about circulatory arrest trough "Inflow Occlusion" technique to correct surgically some cardiac pathologies, such as semilunar valves stenosis. The aim of this study was to compare possible hemodynamic alterations that can occur in dogs submitted to c

2. Total circulatory arrest in dogs for different periods of time using "Inflow Occlusion" technique. Clinical and hemogasometric evaluation / Parada circulatória total em cães por diferentes períodos de tempo através da técnica de "Inflow Occlusion". Avaliação clínica e hemogasométrica
A técnica de "Inflow Occlusion" pode ser utilizada em cirurgias cardíacas quando se pretende manter o coração aberto apenas por alguns minutos, para realização de pequenos reparos. No entanto, a parada circulatória total, evento decorrente da técnica em questão, pode acarretar severas alterações metabólicas e neurológicas, sendo necessária moni

3. Renal cell carcinoma with thrombus in the inferior vena cava: extracorporeal circulation and deep hypothermia without open-chest surgery
INTRODUCTION: Renal cell carcinoma with thrombus in the inferior vena cava and no apparent metastasis requires immediate surgical treatment. Over the last few years, extracorporeal circulation with deep hypothermia and total circulatory arrest have played an increasingly important role in the treatment of diseases not associated with primary cardiovascular d

4. Correção dos Aneurismas da Aorta Torácica e Toracoabdominal: Técnica de Canulação Central.
Introduction: The surgical treatment of the aneurysm of descending thoracic and thoracoabdominal aorta are related with risk of spinal cord ischemic, as well as, coagulation and renal function disorders. Among the spinal cord protection methods, there are liquor drainage, temporary bypass, intercostal arteries implant, deep hypothermia, selective cooling of

5. Total anomalous pulmonary venous connection. Repair using deep hypothermia and circulatory arrest in 44 consecutive infants.
Forty-four consecutive infants aged from 3 days to 10 months underwent repair of total anomalous pulmonary venous connection using deep hypothermia with circulatory arrest. There were eight (18%) early hospital deaths. Using multivariate analysis no significant association could be shown between early mortality and age or weight at operation, preoperative pu

7. Hypothermic protection (26-25 degrees C) without perfusion cooling for surgery of congenital cardiac defects using prolonged occlusion.
Open heart surgery was performed without perfusion under deep hypothermia in 343 patients with congenital heart defects aged from 1 year 3 months to 44 years. Cooling to a temperature of 26-25 degrees C in the oesophagus was achieved by covering the body with crushed ice. The patients were maintained under superficial ether narcosis and they were given morph

8. Transpulmonary Surgical Closure of Patent Ductus Arteriosus with Hypothermic Circulatory Arrest in an Adult Patient
Untreated patent ductus arteriosus carries a higher risk in adults than in children, especially when the defect is large (>4.0 mm in diameter), short, or friable. Therefore, various technical precautions have been suggested for application during surgical closure of a patent ductus arteriosus in an adult. We report the case of a 47-year-old woman with a pate

9. Open heart surgery in first year of life using profound hypothermia (core cooling) and circulatory arrest. Experience with 134 consecutive cases.
Between April 1970 and December 1977, 134 infants aged 2 days to 12 months underwent open heart surgery using profound hypothermia and total circulatory arrest. The technique of bypass (core) cooling is described. Results are reviewed for 4 principal diagnoses: 'simple' transposition of the great vessels, total anomalous pulmonary venous connection, ventricu

10. Changes in serum and urinary potassium levels during profound hypothermia in man
Samples of blood were taken at five to 10-minute intervals during cooling, circulatory arrest, and rewarming in eight consecutive patients undergoing open cardiac surgery under profound hypothermia at nasopharyngeal and oesophageal temperatures of approximately 10°C. and the serum potassium levels were estimated. Urine samples were also collected from six o

11. Repair of traumatic aortic arch to innominate vein fistula under deep hypothermia and circulatory arrest.
Penetrating injuries of the thoracic aorta are usually rapidly lethal. Few patients survive for long enough to undergo surgical treatment. When penetrating injuries of the thoracic aorta are complicated by arteriovenous fistula a correct preoperative diagnosis is important for adequate planning of the surgical repair, and so selective angiography is essentia

12. Total anomalous pulmonary venous connection (surgical technique, early and late results).
Between March 1970 and October 1977, 36 patients underwent correction of total anomalous pulmonary venous connection. The ages ranged from 5 days to 16 years; 27 (75%) were under 1 year and 19 were under 3 months of age at the time of surgery. The overall mortality was 33%. Supracardiac connection was the commonest type and was associated with the lowest hos
