Principal components analysis as a tool for the optimization of experimental conditions.

Principal Components Analysis is used to display the variation in a data set consisting of the free amino-acid patterns in serum from dogs as a function of fasting time. Inhomogeneities found in the data set resulted in an optimization of the experimental conditions. Moreover important observations concerning sampling time and biological variability could be made.

Fistula survival in single needle hemodialysis.

This study presents an average follow up per patient of 33.5 +/- 3.7 and 70.1 +/- 5.9 months (hospital and home dialysis) showing an actuarial fistula survival rate of 86.2% and 85.5% respectively after 5 years. The data suggest a satisfactory survival rate of the fistula when a single needle technique is used in comparison to the survival observed with the two needles technique.

[Arterial thrombosis of the lower limb in patients over 80 years of age. Belgian multicentric experience concerning 802 patients].

This report concerns a joint study of fourteen centres about the treatment of arterial occlusion of the low extremity. Eight hundred and two patients older than 80 years have been studied during a period from 1 to 27 years. The operative mortality was 25.2%. There was no significant difference in mortality between emergency cases and those patients who were operated under elective conditions. Leg amputations are followed by a significant higher mortality than more conservative surgery such as arterial by-pass, sympathectomy or embolectomy. The most frequent cause of death was from cardiopulmonar origin (57%). The postoperative morbidity of cardiac, pulmonary, urinary or infectious origin was frequent (50%). Surgical complications in the true sence of the word are quite rare and their frequency is limited to 7%. The conclusion of this study is that conservative surgery such as reascularisation or sympathectomy is, whenever possible, to be preferred over amputation not only because of their lower mortality (13 to 19%) but also since they permit better revalidation of these elderly patients.

Surgery for arteriovenous fistulas and dilated vessels in the right lung after the Glenn procedure.

A superior vena cava-right pulmonary artery (SVC-RPA) anastomosis was constructed in a 2-year-old boy with tetralogy of Fallot. Ten years later and 5 years after "corrective" surgery without removal of the shunt, cyanosis and heart failure developed. Stereocineangiography and lung scanning revealed arteriovenous fistulas and dilated vessels in the right lung. The SVC-RPA anastomosis was taken down, the SVC being reimplanted in the right atrium and the RPA end being closed with a few stitches. Neither lobectomy nor pneumonectomy was performed. Immediately after the operation and during a follow-up period of almost 2 years, the boy has remained asymptomatic. Whenever a correction is planned in a patient with SVC-RPA anastomosis, the vessels of the right lung should be examined by scanning and angiography. If important arteriovenous fistulas do exist, the affected lung should be excluded from the pulmonary artery circulation.

[Bronchussuture (author's transl)].

We describe the method of manual bronchussuture, used from 1968 until new, which gave us complete satisfaction. Many of the important factors are discussed. The results are analysed and concluding we expose the reasons why we found manual bronchussuture better than any automatic stapling device.

[Ureteral obstruction secondary to aortic femoral by-pass (author's transl)].

We have presented 3 cases of ureteral obstruction secondary to aortic femoral by-pass grafting. This complication has not been frequently reported and we feel that it may be more common than recognised. In all the other published cases the ureter was passing behind the prosthesis but the authors present a surgically proved case where the ureter lies in its normal position. They also prefer the aseptic vascular procedures for reconstruction.

[Indications, method and results of autotransfusion in trauma and vascular surgery (author's transl)].

The authors have used the Bentley Ats 100 system, a disposable autotransfusion unit, in 31 cases of trauma and major vascular surgery. An original method of anticoagulation consisting in heparine (1 mg/kg bodyweight) and priming and flushing of the succion unit with ACD is described. The effect of the autotransfusion on the coagulation and the recent problems and advances are discussed.

[Haemagnioma of the liver in newborn infant (author's transl)].

A case of a giant cavernous and capillary haemangioma of the liver in newborn infant occurred. Resection of the tumor by right hepatic lobectomy was carried out without morbidity or permanent derangement of liver function. There was regeneration of the liver.
