[Clinical-therapeutic aspects and surgical treatment of aortic coarctation associated with hypoplasia of the aortic arch in less than 3-month-old patients].

The surgical treatment of the CoAo plus Hypoplastic Aortic Arch is debated. The point is whether to treat or not the associated tubular hypoplasia performing an extended Resection and "End to End" Anastomosis (ERETE) or a subclavian flap angioplasty (Waldhausen). According to some report in the literature we called an arch hypoplastic if its diameter in the first or second portion was less than the patient body weight plus 1. Between January 1988 and December 1992 in our Institution 38 patients less than 3 months underwent aortic coarctation repair. In 14 cases we were able to consider the aortic arch as hypoplastic. These patients were aged between 3 days and 45 days (median 15 days), the body weight was between 2.6 and 3.9 kgs (median 3.2 kgs). 6 patients had CoAo as isolated lesion, in 3 cases there was Ventricular Septal Defect (VSD) associated. In 5 patients major intracardiac anomalies were associated (1 DORV, 1 TGA, 2 SV, 1 SV+Arterio-Ventricular discordance). In 7 cases in order to treat the arch an ERETE was performed. The other 7 patients had a Waldhausen procedure. In 5 cases a Pulmonary Artery Banding (PAB) was associated, in 1 case a palliative arterial switch operation. The hospital death was 43% (3 patients) in the ERETE group, and 28% (2 patients) in the Waldhausen group. The echocardiography and or angiography performed during the follow-up period showed a nice growth of the arch in both groups. Although from our present data it's impossible to get definitive conclusions, the ERETE doesn't give better result in terms of hospital death and long term aortic arch growth.(ABSTRACT TRUNCATED AT 250 WORDS)

Spinal fusion in degenerative disc disease.

Low back pain caused by degenerative disc disease is of such intensity in a low percentage of cases that surgery is indicated. Surgery must not only stabilize, but it must above all correct the deformity, recovering the disc space. Among all of the methods available circumferential fusion with a double combined approach, that is, anterior and posterior, is held to be the most effective.

[A rare cause of a continuous murmur. Our experience with a newborn infant with a congenital coronary fistula].

Congenital coronary artery fistulas are very rare. The most common connect one of the two coronary arteries with the right cardiac chambers, in particular the right ventricle. So, a left to right shunt appears; furthermore ischemic problems are possible. Notwithstanding in the pediatric age subset the patients are usually free of symptoms. The most important clinical sign is a continuous murmur in the precordium. We report a case of a newborn with a fistula between the right coronary artery and the right ventricle. He presented with the typical murmur; ECG and chest-ray were considered as normal. Echocardiography did not do the diagnosis, and the baby was submitted to a cardiac catheterization. There was a mild left to right shunt (QP/QS = 1.5/1), without pulmonary hypertension. The diagnosis was done by selective coronary angiography. We decided not to close the fistula, and the baby was discharged. Three months later he is still well. In this discussion we consider indications for surgery, and hypothesize a wider application in the future of transcutaneous embolization.

Abdominal pain and acute nephritis in a man with a recent renal transplant.

We describe a patient with renal transplant who developed abdominal pain and acute nephritis in the course of the follow-up. A biopsy of colon lesions revealed CMV inclusions, renal biopsy revealed acute glomerulonephritis with positive CMV-DNA on polymerase chain reaction. The renal disease and bowel symptoms completely resolved after antiviral treatment.

The surgical treatment of thoracolumbar metastases.

Between 1990 and June 1995 a total of 41 patients affected with vertebral metastases caused by neoplasm with different histotypes were treated at the Ist Clinical Orthopaedics and Traumatology Division at the University of Turin. A method proposed by J. Harms was used, nearly always involving a combined anterior and posterior surgical approach. At the Division of Orthopaedics of the Ospedale Maria Adelaide in Turin between 1993 and June 1995 a total of 16 patients affected with vertebral metastases caused by neoplasms of different histotypes were treated. Decompression and posterior stabilization alone using Diapason instrumentation was prevalently performed. Patients with a life expectancy of at least 6 months were treated. Follow-up was obtained by interviewing the patients over the phone during August of 1995. In the cases at the Ist Division of Orthopaedics the number of levels that were instrumented were on the average 2.5, at follow-up 83% of the patients stated that they were satisfied, while only 7.4% were unsatisfied. In the second series (Ospedale Maria Adelaide) the number of levels instrumented was on the average 8, at follow-up 62.5% of the patients said that they were satisfied, while 31.8% said that they were unsatisfied.
