[Conventional and cine-MRT in patients with aneurysms of the abdominal aorta].

We studied 40 patients with aneurysms of the abdominal aorta by MRI. These results were compared with those obtained by real-time sonography (n = 40), angiography (n = 32) and CT (n = 16). In 30 patients the imaging results were compared--as far as possible--with the operative findings. MRI proved more reliable, especially if compared with sonography, in evaluating renal or iliac artery involvement. Mural thrombi were detected more often (93%) by MRI than by CT (85%) or sonography (83%). Cine-MRI showed strong turbulences in 33%. Turbulences did not correlate with the size of the aneurysm.

[Surgical therapy of bronchial cancer. Healing or palliation?].

In spite of the revolutionary innovations concerning diagnostic and intensive care techniques as well as better understanding of tumour biology during the last decade, rates of resection and long-term survival in bronchogenic carcinoma could not be improved. Nevertheless there is no reason for therapeutic nihilism. On the contrary all efforts are to be done in investigation on practicable, suitable, and supportable screening programmes to improve the patients outcome.

[Primary and secondary aorto-intestinal fistula in infrarenal aortic replacement].

During the past 20 years 17 patients with abdominal-aortic-intestinal fistulas have been operated in our department. Hospital-letality accounted till 1986 with 75%. Since then we preferred direct reconstruction by implantation of a vascular graft, covered by omentum in primary fistulas. Hospital letality could be reduced by this management to 0% in primary fistulas by a total survival rate of 67%.

[A new biological vascular prosthesis].

In an experimental study on sheeps a new biologic vascular graft was implanted, 30 x in carotidal, 30 x in aortal position. Only one early occlusion of the graft, due to technical reasons, could be observed. Without aneurysmatic degeneration all graft were in function at the time of harvesting the samples. Morphologically a "revitalisation" of the grafts could be proved.

[Stents in iliac vascular changes].

The results of 79 iliac stent placements in 64 patients are reported. The technical success rate was 96%. The systolic pressure gradient dropped from 44 mmHg before to 2.8 mmHg after stent placement. This differed significantly as compared to a group treated by conventional PTA (gradient 5.8 mmHg). The cumulative patency after 18-20 months was 90%. Angiographic controls up to 19 months after "stenting" demonstrated only one secondary stent occlusion. Iliac stents therefore are a very valuable supplement to classic PTA.

Surgical therapy of oesophageal carcinoma.

During the past 10 years, postoperative mortality associated with surgical treatment of oesophageal carcinoma has been reduced by one-half. However, it appears that all efforts to improve long-term survival with extensive excisional procedures and adjuvant chemotherapy and radiotherapy have failed. Fifty-six of 100 patients presenting to the surgeon with an oesophageal carcinoma have resectable disease. Recent studies suggest that seven of them will die from postoperative complications and 49 patients will be discharged from the hospital after an average of 3 weeks. Of these patients, 27 will survive the first, 12 the second, and ten the fifth year. Although it may be possible to further reduce postoperative complications and mortality, the chances of improving the long-term prognosis of patients with oesophageal carcinoma seem small.

[Monitoring and management of the central nervous system in treatment of tumor cachexia].

After palliative surgery artificial nutrition is indicated primarily in patients receiving postoperative chemotherapy or radiotherapy. The techniques of ambulatory enteral or parenteral nutrition have been standardized during the past decade. They can be used with minimal risk even in patients with advanced cancer. An improvement of the nutritional status can be expected in most of the patients. Further clinical trials are needed to determine whether the patients' quality of life improves.

[Percutaneous transluminal angioplasty of the subclavian artery: technic, results, risks].

The results of 27 percutaneous transluminal angioplasties (PTA) of the subclavian artery are reported in 25 patients. 13 patients complained of claudicatio brachii, 7 also demonstrated symptoms of vertebral-basilar insufficiency. In 5 cases this was the sole indication for PTA. 23 (85.2%) of 27 interventions were limited to the proximal section of the subclavian artery. In 22 (81%) the obstructions were localized on the left side. A technical success could be achieved in 24 (88.9%) of 27 interventions. The angiographic appearance of the homolateral vertebral arteries before and after PTA differed significantly. No PTA led to an occlusion of the previously patent vertebral artery. A retrograde flow was no longer seen after PTA. The haemodynamic significance was also demonstrated by the differences in brachial-occlusion pressures (mean 51 mmHg before, 7 mmHg after PTA). Complete or partial relief was achieved after technically successful PTA in 90% of patients with brachial symptoms and in 50% with vertebral-basilar insufficiency. Complications occurred in one (3.7%) of 27 procedures. Published data on PTA of the subclavian artery are discussed.

[Percutaneous transluminal angioplasty of the infrarenal abdominal aorta].

The results of percutaneous transluminal angioplasty (PTA) (n = 13) of the lower abdominal aorta are reported in 12 patients. The mean patient age was relatively low (46 years). In 7 cases there were isolated aortic obstructions (6 stenoses, 1 occlusion). In the remaining 6 aortic stenoses, there were also major atherosclerotic lesions distally. The mean diameter of the aortic section in which PTA was performed, measured 8.2 mm. The total diameter of the PTA balloon(s) averaged 19.1 mm. The arterial gradient dropped significantly from 41.4 mm Hg (mean) to 2 mm Hg after PTA. The arm-ankle index increased significantly from 0.64 to 0.97. The follow-up included 9 patients; 1 showed restenosis 38 month after PTA. There were no clinically relevant complications. The data published on abdominal PTA in atherosclerotic lesions are summarized.

[Results of surgical treatment of pulmonary metastases].

During the period from 1. 1. 1980-31. 12. 1989 71 patients underwent lung resection for pulmonary metastases. In 21 cases, the primary tumours were sarcoma, in 19 cases carcinoma of the kidney, and 14 cases of melanoma. There were 9 cases of testicular carcinoma, 5 of colorectal carcinoma, and in 1 case each larynx-, oesophagus-, and oral cavity-carcinoma. In 51 patients we could perform an atypical wedge resection, lobectomy was carried out in 19 patients. 1 patient underwent segmental resection. Hospital lethality counted with 0.7%. For all patients, the cumulative survivals revealed an one-year actuarial about 60%, a 3-year actuarial survival of 40%, and a 5-year actuarial survival rate of 38%.

[Ergotism--a rare cause of acute ischemia of the extremities].

Clinical ergotism as seen today results almost exclusively from the excessive intake of ergotamine tartrate in the treatment of migraine headache. Vasospasm of peripheral arteries is the leading clinical picture. Beside formation of collaterals and secondary thrombosis, vasospasm is one of the specific findings in angiography. Early diagnosis and withdrawal of the medication makes complete restitution possible. In all other cases intraarterial or intravenous infusion of sodium nitroprusside or nitroglycerin has turned out to be the most effective therapy. Balloon dilatation or operative intervention are an alternative therapy in those cases, where amputation of the limb seems to be necessary.

[Pathophysiology, diagnosis and therapy of localized frostbite].

Pathophysiology, clinical feature, diagnosis and partially adverse recommendations for therapy are presented. Widening of diagnostic procedures for valuation of the late results by introduction of DSA, fluorescence-video-microscopy and digit phlethysmography are emphasized.

[The type, scope and clinical relevance of early radiologic diagnosis of aneurysms of the popliteal artery].

The popliteal aneurysm as the cause of an acute arterial obliteration pattern is sometimes misinterpreted or overlooked. However, if a femoropopliteal aneurysm is confirmed, the therapeutic approach is substantially different. The article reports on the results of the radiological diagnosis of 17 popliteal aneurysms and the diagnostic relevance of the applied imaging processes is discussed. Real-time sonography and angiography complement each other in their findings and prove to be an indispensable part of preoperative diagnosis.
