[Valvular insufficiency after venous thrombosis. Experimental study].

Venous thrombosis can produce lesions of valvular cusps which are generally ascribe to the phase of thrombus organization. Valvular lesions hold a very important role in the genesis of the post phlebitic chronic venous insufficiency. Experimental thrombosis had been induced in dogs with electrical stimulation of femoral veins to study morphological aspects of valvular cusps in various evolutive phases of thrombosis. Results emphasize too early onset and quick evolution of valvular damage. It can contribute to explain frequent failures of attempted therapy about prevention of post phlebitic syndromes.

[Preliminary experiences with the use of cimetidine in the treatment of acute hemorrhages in the upper gastrointestinal tract].

On the basis of favorable results recently reported in literature with cimetidine in the prevention and therapy of upper gastrointestinal haemorrhages, the Authors have treated a patient with severe haemorrhage from acute gastric ulcer arised after jejunum-ileal massive resection for mesenteric infarction. Result was very good, with stop of haemorrhage and quickly healing of the lesion. This clinical report is of interest particularly in view of high mortality of postoperative haemorrhagic acute gastropaties with therapeutic means, medical or surgical, just now available. At last the particular physiopathological aspects of the case suggested some considerations about mechanisms of action of the Cimetidine.

[Postoperative gastrointestinal hemorrhages after pulmonary resections (author's transly].

Postoperative gastrointestinal hemorrhages are a infrequent complication of pulmonary resections. Nevertheless they are threatening seriously patient's life because a critical illness as gastrointestinal hemorrhage in such casses hit patients whose vital functions are compromised from recent thoracic surgery. The pathogenetic questions, as well critical problems of diagnosis and treatment, are discussed on the basis of three observed cases.

[The complications of pulmonary resection surgery: the experience of 200 consecutive cases].

Postoperative complications observed in 200 patients after pulmonary resection (66 pneumonectomies--30%, 106 lobectomies--53% and 28 wedge resections--17%) are presented. Surgical operations were carried out in 86% of cases for cancer, in 16% for benign lesions. Major complications were: lobar atelectasis, bronchopneumonia, pulmonary embolism, respiratory insufficiency, bronchial fistula, ventricular tachyarrhythmia, altogether they concerned 21% of the cases. Their incidence was not significantly influenced by the extension of resection (the latter, on the contrary, influenced postoperative mortality as much as 4.5% after pneumonectomy, 2.8% after lobectomy and 0% after wedge resection), age of patients under or over 70 years, functional respiratory reserve, or associated cardiovascular diseases. On the contrary, the advanced stage of disease in neoplastic patients was significant for major complications. An adequate monitoring of minor respiratory and cardiac complications is recommended to reduce the incidence of major ones and their control when present. In authors' experience, in fact, postoperative mortality was overall 3% following such behaviour.

[Intra- and postoperative changes in blood viscosity].

Blood and plasma viscosity has been controlled in a group of patients undergone to aorto-iliac reconstruction and in a group of control after thyroidectomy, cholecystectomy, and hernioplasty. The hemodilution induced by intraoperative infusion in the vascular reconstruction produced an important decrease of hematic and plasmatic viscosity which lasted for several days after the operation. Removing the hemodilution effect by a mathematical correction of the viscosity measured values to a standard haematocrit, it has demonstrated as surgical operation, apart from its entity, promoted an increase of the viscosity which persisted long in the postoperative course. For what it concerns the risk of postoperative thrombosis from one side protective effect of hemodilution is confirmed, from the other, in absence of the hemodilution, it would be useful to continue the antithrombotic prophylaxis longer the perioperative time as usual.
