[Resection for pulmonary metastases: results and prognosis (author's transl)].

From 1955 to 1975 in 25 patients lung surgery has been carried out because of intrapulmonary metastases of extrapulmonary malignant growth. 6 patients survived longer than 5 years. There was no relationship between survival time and length of the time interval between initial surgery (primary) and second operation (i.e. diagnosis of pulmonary lesion). On the other hand a definite relationship resulted for survival time and the size of the growth. In bad-risk patients surgery for metastatic lung cancer is not indicated, but it is very successful in selected cases.

[Complete bilateral renal vein occlusion in a patient with right sided hypernephroma and renal insufficiency: report of successful thrombectomy and nephrectomy].

A 66 year old female patient was successfully operated following complete obstruction of the inferior vena cava and left renal vein by tumor thrombi from a right sided hypernephroma. The effect of the compensatory development of venous collaterals of the left kidney and the therapeutic consequences of a thrombectomy following long standing thrombosis of the left vein are discussed.

[Profundaplasty--a palliative operation in leg arterial occlusion of the aged?].

In a retrospective study the relevance of revascularisation of the deep femoral artery was evaluated in 100 geriatric patients with obliterative atherosclerosis. The results of profundaplasty were good in 91% of patients with claudication (follow-up 47 months). In patients with rest pain the limb salvage rate was 77% (follow-up 39 months). In comparison with femoropopliteal or femorocrural bypass the results were at least even but had lower lethality. In a state of gangrene the limb salvage rate was 39% overall (follow-up 31 months). Diabetics had a limb salvage rate of 28% versus 43% in non diabetics. In a state of claudication and rest pain with stenosis of the deep femoral artery its revascularisation is in our view the treatment of first choice. In a state of gangrene bypass implantation, especially in diabetics, seems to have better results, but as additional palliation before primary amputation profundaplasty should be performed.

[Surgical therapy of cerebrovascular insufficiency with reference to advanced age].

After brief discussion of epidemiology, aetiology, localization, diagnosis and surgical management of vascular stenoses leading to cerebral insufficiency, the results of 433 carotid artery TEAs are reported. Short- and long-term results were investigated to determine to what extent age of the patients affects outcome. The analysis of our patients sample showed with respect to perioperative mortality, morbidity and long-term outcome no significant difference between the under- and over-70-year age groups. In stage I (asymptomatic bruits) the perioperative mortality of the younger group (N = 119) was 1% and in the older group no perioperative death occurred. The long-term survival rate and the proportion of patients without neurological dysfunction after 4 years was 65% and 85% respectively for the younger group and 88% and 80% for the over 70-year age group. In stage II patients (with transient ischaemic attacks) the perioperative mortality was the same for both groups (2%). The long-term survival rate for the younger group (N = 106) was 77% and 76% in the older group (N = 91) proportion of patients without neurological dysfunction was 87% for the younger group and 93% for the older patient sample. There were no patients with stage III occlusion (acute stroke) in our patient sample. In stage IV (completed stroke) the younger patients had a perioperative mortality of 5.7%. In the older group (N = 18) no patient died perioperatively. The 2-year survival rates were 61% for the older age group and 57% für the younger. The corresponding proportions of patients without neurological dysfunction after 4 years were 83% and 71% for the older and younger patient groups respectively.
