A traumatic transection of the upper descending thoracic aorta, undiagnosed, was complicated on the tenth day by an acute obstruction of the descending thoracic aorta. The upper body hypertension resulted in generalised convulsions and cardiac failure with pulmonary oedema. The lower body ischemia resulted in paraplegia, acute ischemia of the lower limbs, liver failure and anuria. An emergency revascularisation of the lower body was achieved by axillary-bifemoral bypass. The improvement of the clinical status allowed complete repair of the aortic transection two days after the extra-anatomic revascularisation. This case emphasizes the severity of the cases with impaired blood flow to the lower body and the benefit of the extra-anatomic bypass in pathology of the upper descending thoracic aorta when complete repair of the aortic transection is associated with an extremely high risk.

An analysis of 4 cases of the thrombotic thrombocytopenia in children of 4 to 10 years of age is performed. The disease was characterized by fever, purpura, headache and abdominal pains, arterial hypertension, microangiopathic haemolytic anemia, thrombocytopenia, increase of blood urea and serum creatinine, micro-haematuria and proteinuria. The duration of the disease was from 4 days to 7 months. Anuria, gangrene of the ears, scrotum, penis and soft tissues of legs and feet were registered in a 5-year-old patient with a fulminant disease. The cause of death of other patients was heart failure with acute lung oedema, brain haemorrhages and haemorrhagic pancreonecrosis. The diagnosis of the thrombotic thrombocytopenia was confirmed by the finding in the autopsy material of thrombotic microangiopathy of small arteries, veins, arterioles, venules and capillaries in kidneys and other organs and tissues. Kidney damage in fulminant disease is complicated by segmentary cortical necrosis, in a more prolonged disease--by glomerulosclerosis or mesangio-capillary glomerulonephritis.

We reported a 29-year-old man with active endocarditis complicating aortic and mitral valve regurgitation. The echocardiogram showed a mycotic aneurysm at aortic valvular annulus and a aneurysm of mitral valve. Heart failure was progressive and caused anuria. Prior to emergent double valve replacement, 2,500 ml of water was removed. Then hemodynamics became stationary. Urination was good during and after operation. In this case, complicating acute renal failure, dehydration with extracorporeal ultrafiltration method was very effective for improvement of hemodynamics.

A case is reported of a 40 year-old man, on the waiting-list for heart transplantation, who developed terminal heart failure. Using an Opticath catheter and a radial artery catheter, SV(-)O2 was monitored continuously, and cardiac output, pulmonary arterial and wedged pressures, and right atrial pressure were repeatedly measured. Despite appropriate treatment (adrenaline, dobutamine, glyceryl trinitrate), the patient remained in anuria and cardiogenic shock. External circulatory support (ECS) (BVS 5000 Abiomed) was therefore used as a bridge to cardiac transplantation. The resultant increase in systemic blood flow led to an early and fast rise in SV(-)O2, from 40% to 73%, with a decrease in the oxygen extraction ratio (ERO2) from 50 to 30%. Serum lactate concentrations returned to normal within the first six hours of ECS (less than 120 mg.l-1). During the first 24 h of ECS, SV(-)O2 decreased and ERO2 rose significantly on two occasions: during an episode of shivering, and another of restlessness during nursing. An attempt at weaning the patient from the ventilator at the 39th h also led to a sudden decrease in SV(-)O2, with a rise in ERO2. The Opticath catheter was finally removed after 150 h of ECS because of a decrease in reflected light intensity.

After 4 weeks of total parenteral nutrition (TPN), a 12-yr-old girl exhibited an acute heart failure with high cardiac output, anuria, and severe lactic acidosis. The clinical, hemodynamic, and biological data suggested the diagnosis of shoshin beriberi which was proved by the low erythrocyte transketolase activity with elevated "TPP effect" and by the dramatic improvement of the patient after thiamin administration. Thiamin deficiency and severe neurological disorders have been described during long-term parenteral nutrition. To our knowledge, this is the first report of the cardiovascular complication of this vitamin deprivation in long-term TPN.

Emphysematous pyelonephritis is a severe infection characterized by the presence of gas within the renal parenchyma and perirenal tissues. Two cases of this disease are presented. They were the 16th and 17th case reported in Japan. Case 1 was a 63-year-old woman with diabetes mellitus and liver cirrhosis. She was hospitalized for abdominal pain and anuria. Renal X-rays showed a gas shadow in and around the left kidney, but no evidence of upper urinary tract obstruction. Although hemodialysis was done, she died of heart failure. Case 2 was a 54-year-old man with diabetes mellitus was admitted with the complaint of fever and left abdominal pain. Renal X-rays showed a gas shadow in and around the left kidney but no evidence of upper urinary tract obstruction. He was treated with intensive antibiotic therapy, control of blood sugar, intravenous drips and percutaneous drainage. Clinical features improved, but deteriorated after 40 days of therapy. The gas shadow remained unchanged on CT scanning, and aortography showed the occlusion of the left renal artery. Nephrectomy was done after 50 days. Seventeen cases of emphysematous pyelonephritis in the literature including our cases are reviewed, especially the choice of the treatment is discussed.

Six children with refractory heart failure were treated by continuous arteriovenous haemofiltration. The cause of the failure was postoperative fluid overload or low cardiac output with anuria or oliguria. This produced a mean (2 SD) negative fluid balance of 1.4 (0.6) ml/kg/h and reduced mean (2 SD) body weight from 4.7 (2.2) to 4.2 (2.3) kg over a period of 57.5 (31.1) hours. Central venous pressure fell significantly from 13.7 (3.1) to 7.7 (0.7) mm Hg while the mean (2 SD) arterial pressure increased significantly from 44.6 (5.5) to 52.6 (5.1) mm Hg. In three infants urine production resumed when normal blood volume had been achieved. The other three infants needed further haemofiltration because of prolonged renal failure. All but one was weaned from artificial ventilation and catecholamine treatment. No adverse haemodynamic effects were noted. One child need operation for a femoral artery thrombosis after 12 days of continuous arteriovenous haemofiltration.

Fourteen patients with familial juvenile nephronophthisis are described, eight of whom displayed one or more additional disorders. One boy with short limbed dwarfism and an abnormal chest was considered to have Jeune's syndrome; review of the published reports supports the view that nephronophthisis is the principal cause of renal failure in this disorder. Another patient with renal failure and retinitis pigmentosa at presentation developed progressive neurological and neuromuscular impairment leading to the discovery of ragged red fibre disease (mitochondrial cytopathy). Cardiomyopathy was present in this and one other patient. Tapeto-retinal degeneration, hepatic fibrosis, cerebellar ataxia, and oculomotor apraxia were among the other disorders encountered. Three patients presented in extremis with acute heart failure and irreversible oligo-anuria and this complication developed in another child who was already known to have nephronophthisis. Awareness of this disease and its associations is important for early diagnosis and appropriate management.

Sixteen infants, 2 to 35 days of age, had acute renal failure, a diagnosis based on serum creatinine concentrations greater than 1.5 mg/dL for at least 24 hours. Eight infants were oliguric (urine flow less than 1.0 mL/kg/h) whereas the remainder were nonoliguric. To determine clinical parameters useful in prognosis, urine flow rate, duration of anuria, peak serum creatinine, urea (BUN) concentration, and nuclide uptake by scintigraphy were correlated with recovery. Nine infants had acute renal failure secondary to perinatal asphyxia, three had acute renal failure as a result of congenital cardiovascular disease, and four had major renal anomalies. Four oliguric patients died: three of renal failure and one of heart failure. All nonoliguric infants survived with mean follow-up serum creatinine concentration of 0.8 +/- 0.5 (SD) mg/dL whereas that of oliguric survivors was 0.6 +/- 0.3 mg/dL. Peak serum creatinine concentration did not differ between those patients who were dying and those recovering. All infants who were dying remained anuric at least four days and revealed no renal uptake of nuclide. Eleven survivors were anuric three days or less, and renal perfusion was detectable by scintigraphy in each case. However, the remaining survivor (with bilateral renal vein thrombosis) recovered after 15 days of anuria despite nonvisualization of kidneys by scintigraphy. In neonates with ischemic acute renal failure, lack of oliguria and the presence of identifiable renal uptake of nuclide suggest a favorable prognosis.

This study presents an analysis of the influence of the site of rupture of abdominal aortic aneurysms on the postoperative survival rate. A series of 226 patients, who underwent emergency operations for ruptured aneurysms, is examined. The three most important methods of rupture are: (1) Retroperitoneal rupture: this type is associated with a very high mortality (52.8% in our experience), which reaches almost 75% when the posterior parietal peritoneum tears and massive intraperitoneal bleeding occurs. This mortality is related to the amount of blood loss, hypovolemic shock, the number of transfused blood units and, especially, to increasing renal insufficiency. (2) Rupture into the inferior vena cava: in this event the mortality rate it less severe (38.4% in our experience) and it is mostly related to the occurrence of an high output cardiac failure, as well as to oliguria or anuria following renal venous hypertension. (3) Enteric rupture: this is, in our experience, the most uncommon event. It carries a high mortality rate (50%). The copious bleeding, which is unrestricted in hollow organs, explains the dangerous hypovolemic shock, while massive blood reabsorption from the enteric tract leads to a renal insufficiency.
