[The radiological diagnosis of acute intestinal ischaemia (author's transl)].

Angiography was carried out in 27 patients with acute intestinal ischaemia. In 23 patients a primary, and in four a secondary vascular cause was found. Plain films are of little value in the early diagnosis of mesenteric infarcts, since radiologically demonstrable changes first develop after 10 to 12 hours following the incident. A definitive early diagnosis of an acute mesenteric infarct can only be made by angiography. Surgical intervention for proximal mesenteric artery occlusion is only likely to be successful if carried out within 10 hours. 80% of six patients with major occlusions and five with angiospastic mesenteric insufficiency died. One out of three embolectomies was successful. Amongst seven patients with occlusions of jejunal and ileal branches, just over half died; three out of four embolectomies were successful. Five patients with ileal occlusions survived.

[Computer tomography for gynaecological carcinomas (authors's transl)].

The morphology of gynaecological cancers was studied by computer tomography in 220 ovarian and uterine carcinomas. The value of the method with regard to staging and diagnosis is discussed. Non-invasive computer tomography for gynaecological cancers is indicated. 1. In order to obtain significant information regarding the extent of the tumour and its regional metastases. 2. In order to reduce the need for other invasive diagnostic measures. 3. For improving treatment by interdisciplinary procedures, particularly with respect to planning of radiation therapy. 4. For the early recognition of recurrences and for objective evaluation of the result of treatment.

[The computer tomographic diagnosis of echinococcosis (author's transl)].

The computer tomographic appearances and differential diagnosis in 22 patients with echinococcosis are described; of these, twelve were of the cystic and ten of the alveolar type. The computer tomographic appearances are characterised by the presence of daughter cysts (66%) within the sharply demarkated parasitic cyst of water density. In the absence of daughter cysts, a definite aetiological diagnosis cannot be made, although there is a tendency to calcification of the occasionally multiple echinococcus cysts. The computer tomographic appearances of advanced alveolar echinococcosis are characterised by partial collequative necrosis, with calcification around the necrotic areas (90%). The absence of CT evidence of partial necrosis and calcification of the pseudotumour makes it difficult to establish a specific diagnosis. The conclusive and non-invasive character of the procedure and its reproducability makes computer tomography the method of choice for the diagnosis and follow-up of echinococcosis.

[Computer tomography following renal tumour embolisation (author's transl)].

CT examination of eight patients after palliative embolisation of a malignant renal tumour showed a distinct reduction in renal size, beginning after a week and lasting for two or three months. In the patients who survived for more than six to twelve months, the tumor increased in size, as was shown by an increase of tumour volume and tumour revascularisation which could also be demonstrated by computer tomography. Gas in the tumour after embolisation was seen in four out of six cases within the first week and in another case it persisted for five months, without evidence of the presence of a renal abscess or urinary sepsis.

Tibial torsion calculated by computerised tomography and compared to other methods of measurement.

A new method for the measurement of tibial torsion using computerised transverse tomography is presented. Its accuracy is equal to that of cadaveric skeletal measurement. This method may be used in patients with unilateral post-traumatic torsional deformities, especially when these are combined with genu varum or valgum. The study of torsional aberrations in connection with congenital abnormalities of the foot is of further interest.

[Computer tomography as aid for surgical indication and choice of time in acute pancreatitis].

When initial clinical improvement of acute pancreatitis is followed by secondary deterioration, a local complication must be suspected, and surgery may be required to drain infected fluid collections and to debridge or resect necrotic and sequestering parts of the pancreas and/or peripancreatic fatty tissue. Clinical examination, laboratory investigations, and conventional radiology have failed to give clear information as to the local process in the retroperitoneum. The indication for surgery has therefore traditionally been based upon the systemic manifestations of sepsis and distant organ failure, which may account for the still high mortality in this group of patients. Computerised axial tomography (CT) has been shown to be of value in making an earlier diagnosis of the local complications of acute pancreatitis and providing more detailed informations upon which to base the type and extent of the surgical procedure. In the last 1 1/2 years CT has been used prospectively by the authors for initial assessment and follow-up of the course in all cases of severe acute pancreatitis. In this series 3 out of 11 operated patients died, compared to 18 out of 33 comparable cases during the preceding 5-year period when CT was not available in our hospital. In 2 of the 3 fatalities, a perforation of the colon had been present at the time of referral. These preliminary results suggest that CT is of value in the management of this difficult problem and has helped to reduce mortality from the complications of acute pancreatitis.

[Embolization therapy of renal hemorrhage of non-malignant etiology (author's transl)].

Superselective embolization of renal hemorrhage of benign etiology proves to be an effective method with rare complications and low morbidity, which allows to stop the bleeding in almost all of the cases. Two of our own cases are compared to 24 in the literature; and the results are discussed. This type of embolization is indicated mainly in cases with surgically uncontrollable renal hemorrhage and rarely as an alternative to surgical intervention.

Radiologic investigation of splenic trauma.

The radiologic findings in blunt and penetrating splenic injuries are discussed with emphasis on the angiographic demonstration of these injuries. The angiographic findings are correlated with the time interval between trauma and radiologic investigation.

[Computer tomography in acute pancreatitis (author's transl)].

The computer tomographic appearances of acute pancreatitis have been analysed 33 patients. It is usually a simple matter to distinguish between the acute, oedematous pancreatitis, which can be treated conservatively, and the suppurative pancreatitis with haemorrhagic and necrotising features, which require surgical exploration.

[Computer tomography following blunt abdominal trauma (author's transl)].

The computer tomographic appearances of lesions of parenchymatous organs following blunt abdominal trauma are described in 13 patients (five liver, four renal, two splenic and two pancreatic injuries). The value of abdominal computer tomography is discussed in relation to the interval between injury and time of abdominal examination and compared with the diagnostic value of abdominal angiography.

[Computer tomography and retroperitoneal fibrosis (Ormond's disease) (author's transl)].

Four patients with retroperitoneal fibrosis (Ormond's disease) were examined by computer tomography; the appearances are described and the differential diagnosis discussed. Computer tomography clearly defines the proliferative-inflammatory process and together with conventional radiology, angiography and lymphangiography it permits a presumptive diagnosis of retroperitoneal fibrosis. The non-invasive nature of computer tomography makes it the method of choice for follow-up of this disease.
