The postoperative courses of 26 patients admitted to an Intensive Care Unit after different types of surgery on their portal tree are studied. All were diagnosed as having portal hypertension secondary to chronic liver disease and had presented one or more episodes of bleeding. Those complications of greater risk with an important early mortality rate are: 1) recurrence of the gastrointestinal hemorrhage, independently of the type of lesion which originates it; 2) recurrence of ascites because these patients more often develop dehiscence of the abdominal wall, serious dilutional hyponatremia and severe functional renal insufficiency; 3) acute renal failure, both functional or caused by an organic tubulo-interstitial nephropathy; 4) peritonitis; 5) persistent hepatolytic episode; 6) hyperdynamic heart failure; and 7) re-operations in general, independently of the causes. The frequency of these complications and the greater or lesser seriousness of their development in the postoperative period are dependent on: 1) the age of the patient with a better prognosis for those under 50; 2) the histopathologic type of the hepatic lesion, with hepatic fibrosis having a more favourable evolution in comparison with cirrhosis; 3) the degree of decompensation of the hepatopathy immediately before the operation, evaluating signs of functional hepatic deficit, cytolysis and degree of portal hypertension. The greater the preoperative activity, the worse the postsurgical prognosis. 4) The elective or urgent character of the surgery. During the postoperative course of emergency surgery all types of complications may appear. The emergency operation which has effectively achieved the stopping of the esophageal bleeding has been the porto-azygos disconnection, which allows later a portosystemic shunt with a greater probability of success. 5) The type of anastomosis carried out. Radicular shunts were those which had a lower postoperative mortality rate and those which progressed better because of the small number of problems occurring in the early postoperative period.

The pathological changes in blood vessels observed in primary (essential hypertension) are similar to those seen in secondary hypertension due to renal disease or other causes. In benign hypertension, the major changes are in the small arteries and arterioles especially in the kidney. Interlobular arteries exhibit intimal thickening and duplication of the elastic lamina (elastosis) and there is hyaline change in the media of many arterioles. In some respects these changes are an accentuation of vessel ageing. Malignant hypertension usually presents in a younger age group (35--50 years) and is characterized pathologically by fibrous endarteritis in the interlobular arteries of the kidney and fibrinoid necrosis in the walls of a proportion of the efferent glomerular arterioles. Similar vessel changes are seen in other organs but many of the pathological changes in the heart and brain of patients with benign hypertension are related to the accentuation of arterosclerosis. There is an increased mortality from cardiac failure, myocardial infarction, cerebral haemorrhage and subarachnoid haemorrhage due to ruptured berry aneurysms in patients with benign hypertension. Although there is ischaemic damage to the kidneys in benign hypertension, death from renal failure is uncommon. Severe ischaemic damage to renal glomeruli and renal failure does, however, occur in malignant hypertension.

Minoxidil, a potent vasodilator antihypertensive agent, was given to 14 patients with severe hypertension uncontrolled by conventional agents. Thirteen patients had elevated serum creatinine levels. Over a period of 20 months (mean duration of administration) minoxidil lowered blood pressure from 194/124 to 147/90 mm Hg (mean values), in combination with furosemide and a sympathetic inhibitor (usually propranolol). Progression of preexisting renal disease was halted in all but three patients. Fluid retention, cardiac failure, and angina were troublesome side effects. The occurrence of hypertrichosis also limited the usefulness of minoxidil, particularly in female patients.

The paper reports two siblings, 6 and 3 3/4 years old, with a congenital nephropathy (nephronophthisis), retinitis pigmentosa, heart failure and peripheral dysostosis. The severe histological changes of the kidneys with tubular atrophy and interstitial fibrosis caused the death of the older sister at the age of 7 years. The symptoms of our patients are discussed in comparison to the syndrome described by MAINZER et al.

A 65 year old man developed endocarditis and septicemia due to Hemophilus aphrophilus, a Gram-negative coccobacillus. Renal rather than cardiac failure was the principal feature of his illness and renal biopsy was compatible with glomerulonephritis secondary to septicemia. Rapid recovery of renal function and improvement of the glomerular lesion followed antibiotic treatment of the septicemia. This case illustrates the renal damage that can occur in association with septicemia due to rarer infectious agents. As with more common organisms, specific antimicrobial therapy leads to rapid improvement of the nephropathy.

One hundred thirty-seven courses of furosemide therapy were given to 106 hospitalized pediatric patients with salt and water retention associated with cardiac or renal disease. The diuretic was effective and safe in the pediatric age group when administered acutely as a parenteral medication and over a long-term course by the oral route in the doses and at the time intervals used in this study. On the basis of each kilogram of body weight, the infants with edema as a result of cardiac failure and the children with edema secondary to renal disease responded equally well to furosemide therapy.

The authors report on the myocardiopathy of seven patients with end-stage renal disease, characterized by fever, in four patients; tachycardia, gallop rhythm, pericardial rub, in most of patients; signs and symptoms of cardiac failure and increased cardiac area and alterations of the EKG in all patients. Good remission of the symptoms ws achieved in two patients by hemodialysis and by successful renal transplantation in the others. The likely etiologic factors of the syndrome are discussed.

After serum creatinine levels exceeded 10mg/100ml, median survival was 55 days (to death or dialysis) in a group of 112 patients with chronic renal disease. Renal failure was partially reversible in 29 patients, partially accounting for prolonged survival. Those with polycystic kidneys, pyelonephritis, or obstructive nephropathy survived longer,partially because of more frequent reversibility and a slower increase in serum creatinine concentration. Kiabetic nephropathy, myelomatous kidneys, and amyloidosis were associated with shorter survival, less frequent reversibility, and more rapid progression. Urinary infection and extracellular volume depletion often accounted for partially reversible renal failure and prolonged survival. Blood pressure and age were not prognostic variables, while coexistent heart failure shortened survival. Survival correlated significantly with sodium excretion.

Renal hypertension can usually be recognized only by examining all the features of the hypertensive illness. On the other hand, the investigation of a case of hypertension whose genesis was previously unclear can lead to the diagnosis of a hitherto unrecognized renal disease. The blood pressure values found in patients with renal hypertension are of widely differing degrees of severity. Slight rises in blood pressure (e.g. 140/90 mm Hg), can be a sign of renal disease in adolescent patients. 10-15% of the cases of chronic renal hypertension develop into malignant hypertension. High diastolic values above 120 mm Hg without renal symptomatology and without reduced renal function speak against a primary renal cause of the rise in blood pressure. The finding of hypertension developing during the course of renal disease is, with respect to the hypertensive cardiovascular complications, just as important as in the case of essential hypertension. Complications which can occur during renal hypertension include cardiac insufficiency, hypertensive encephalopathy, retinopathy, hypertensive crises and acceleration of the renal disease.

Signs of heart failure due to cardiac tamponade developed in a young dog with previously unrecognized renal disease. The uremic syndrome was considered the likely cause of the effusive pericarditis found at necropsy. In a review of necropsy records from 150 dogs with renal disease, 11 had pericardial lesions.
