[Cardiac transplantation at the University Hospital Center of Nantes. 2 years' experience].

Between March, 1985 and April, 1987, 25 orthotopic heart transplantations were performed in 20 men and 5 women aged from 17 to 58 years (mean 42 years) on account of cardiomyopathy (n = 15), ischaemic heart disease (n = 6) or miscellaneous lesions (n = 4). The immunosuppressive treatment consisted of antilymphocyte serum and corticosteroids during 10 days; cyclosporine was introduced on the 7th day and continued thereafter in association with low-dose corticosteroid therapy. Endomyocardial biopsies were performed. Acute rejection, responsible for 2 deaths (one on the 10th day, the other in the 10th week), usually occurred within the first 3 months. Infections were frequent and often serious, resulting in one death in the 7th week. One out of patients had to be treated for arterial hypertension, and 3 patients presented with renal impairment (blood creatinine over 200 mumoles/l). The actuarial survival rate at 2 years is 84 p. 100. More than one-half of the patients have resumed social and occupational activities.

Treatment of subdiaphragmatic Hodgkin's disease: long-term results and side effects.

To evaluate the results, prognostic factors and especially side-effects of the treatment for subdiaphragmatic Hodgkin's disease (SHD) a retrospective study was conducted in the Haematology Departments and in the Cancer Centres of Nancy and Strasbourg between 1976 and 1990; 55 patients corresponding to the IA to IIB SHD stages were analysed. The median age was 45 years. In accordance with Ann Arbor classification, we observed 12 CS IA (21.3%), 2 CS IB (3.5%), 14 CS IIA (25.4%) and 27 CS IIB (49.7%). Twenty-five patients (45.4%) underwent laparotomy with spleen involvement in 10 cases. Fifteen patients (27.3%) had exclusive radiotherapy, 10 by inverted-Y field with or without splenic field, 5 by limited field to inguinal and homolateral iliac nodes. Forty patients had prior chemotherapy, 18 by MOPP protocol, 18 by hybrid MOPP/ABVD protocol and 4 by other schemes. The total dose delivered ranged from 26 to 45 Gy. With a median follow-up of 8 years, the overall and disease specific survival rates are respectively 61% and 83% at 10 years. Nine patients relapsed (16.4%), 4 among the 15 (26.6%) treated by exclusive irradiation and 5 among the 40 (12.5%) treated by combined therapy. We observed 8.3%, 21.4% and 18.5% of relapses respectively among the clinical stages IA, IIA and IIB. Eleven patients (20%) developed a second cancer. Twenty-six long-term complications were noted, nine of which concerned the digestive system. The only significant prognostic factor is age, with 10-year specific survival rates of 96% and 66% respectively for patients younger and older than 50 years (p=0.0003). Our data confirm that the most appropriate treatment for stage IA is exclusive radiotherapy and combined therapy for all other cases. With the use of CT-scan and eventually lymphography, the laparotomy is reserved only for cases with an uncertain diagnosis. Tobacco use is also clearly a risk factor in our series for late vascular complications and second cancers.

[The new LEM caval filter in the prevention of pulmonary embolism. Preliminary results of a French multicenter study].

Preliminary results are reported of a prospective multicenter trial of a new caval filter (LEM*) implanted by the percutaneous jugular route in 100 patients, 55 men and 45 women, mean age 67 +/- 13 years, to produce partial interruption of inferior vena cava (IVC). Of the 100 attempts to insert the LEM* filter, 2 failures to catheterize the jugular vessel were reported, 98 filters being placed in the IVC with 82 implantation considered adequate. Of the remaining 16 cases, the filter was inclined (7 cases) or incompletely open (9 cases) with total lack of success in 3 cases. Overall efficacy was obtained therefore in 95 cases. Follow up included 94 patients seen after one week, 63 after 3 months and 10 after 6 months: 3 embolic recurrences were noted (3.2%) of cases. None of the 8 deaths reported was related to the thromboembolic disease. Standard frontal abdominal radiographic images showed migration of filter in 13 cases (13.7%) not exceeding the height of a vertebral body: 9 were caudal and 4 proximal, the LEM* filter remaining within the IVC. Phlebocavography in 90 cases showed the IVC to be permeable in 84 cases (93.3%). Incomplete opening or inclination of filter had no effect on the course. These findings demonstrate that the advantages of the LEM* filter include: a percutaneous introduction allowing rapid, certain insertion, and a form studied for limitation of inclination and avoidance of perforation of the IVC.(ABSTRACT TRUNCATED AT 250 WORDS)
