Ileocaeco-urethroplasty after total cystectomy for bladder cancer.

Eleven cases of ileocaeco-urethroplasty, performed over a 2-year period, are presented. The patients had low grade bladder cancer infiltrating into but not extending beyond the muscle layer (B-T3a). Following radiotherapy a total cystectomy was performed up to the verumontanum; afterwards the prostatic cuff was anastomosed to an ileocaecal segment. The patients have been followed up for 13 to 39 months. One died from metastases after 30 months. The others are alive and in good psychological condition, with satisfactory micturition. We believe this surgical option deserves more careful consideration.

[Vectorcardiographic study of an unusual form of hypertrophic cardiomyopathy].

The many aspects of heart electrical activity in hypertrophic cardiomyopathy have recently been described in numerous occasions. A vectorcardiographic study was made of two sisters with an echocardiographic diagnosis of hypertrophy of the free wall of the left ventricle. Both the ECG and the VCG shown evidence of pseudonecrosis and pseudoischaemia associated with left intraventricular conduction disturbances and left atrial dilatation. It is felt that echocardiography, and the two-dimensional examination in particular, is essential in the diagnosis of myocardial hypertrophy, but it is pointed out that ECG, and above all VCG, may sometimes indicate its site and extent with a good degree of approximation.

[Mono- and bi-dimensional echocardiographic study of a bicuspid aortic valve].

With M-mode echocardiography a bicuspid aortic valve can be diagnosed by its eccentric diastolic echoes, particularly when the eccentricity index exceeds 1, 3. However, many false positives and false negatives have been reported. Two-dimensional echocardiography, which identifies the commissures and the closure lines, can make the diagnosis more accurate. With this technique we studied 15 patients with a bicuspid aortic valve and 20 normal subjects. We found 3 different patterns according to the position of the closure line, which can be "horizontal", "vertical" and "oblique". Whenever the closure line is "horizontal", that is perpendicular to the direction of the ultrasonic beam, the M-mode echoes from the valve in diastole appear to be centrally located within the aortic root (false negatives). On the contrary, if the closure line is "vertical", that is parallel to the echo beam, "the echoes" are eccentric (diagnostic images). When the closure line is obliquely oriented, the ultrasonic images can be either central or eccentric. Two-dimensional echocardiography identified 5 "horizontal", 3 "vertical" and 7 "oblique" closure lines. It thus helped clarify the M-mode errors and proved to be more reliable for the diagnosis of bicuspid aortic valve.

[Echocardiographic study of hypertrophic cardiomyopathy localized in the free wall of the left ventricle].

Previous studies have shown that the Hypertrophic Cardiomyopathy may involve the left ventricle free wall, without involving the intraventricular septum. We describe two young sisters who were suspected of having Hypertrophic Cardiomyopathy because of their family history and because of abnormal electrocardiographic findings. M-mode echocardiography showed normal ventricular septal thickness, increased thickness of the left ventricular posterior wall, decreased diastolic posterior wall velocity, normal left ventricular outflow tract. Two-dimensional echocardiography showed that hypertrophy was limited to left ventricular free wall, especially to the lateral and anterior segments. Echocardiography can thus identify unusual forms of hypertrophic cardiomyopathy.
