[Atypical aneurysms of the abdominal aorta].

The authors submit a report on two patients with pseudoaneurysmatic bulging in the subrenal portion of the abdominal aorta. They present detailed histological findings in the two operated patients and discuss the aetiology of these formations. They draw attention on the failure of aortographic examinations in the diagnosis of these formations and the necessity of sonographic or CT examination. During surgery only partial resection of these formations is possible with subsequent reconstruction of the arterial circulation. The long-term results of these operations are favourable.

[Evaluation of the size of the spleen using computer tomography].

The authors describe the examination, diagnostic possibilities and difficulties associated with the diagnosis of the spleen by means of computed tomography. The finding obtained by computed tomography is evaluated as splenomegaly when two of the three main dimension are greater than the maximal values reported, or when the lienal index is higher than 440. From the practical aspect the decision on splenomegaly is facilitated by the position of the anterior margin of the spleen in relation to the medioaxillary line. Splenomegaly is the most frequent pathological finding on the spleen. The authors give an account of causes of splenomegaly and their own experience with the diagnosis of anomalies, cystic processes, tumours, injuries and obstructions of the lienal vessels.

[Computer tomography of the renal bed after nephrectomy].

An early diagnosis of the tumour relapse after performed nephrectomy for a malignant kidney tumour is necessary in order to influence further fate of the patient. The most suitable method for determining a correct diagnosis is computer tomography. The authors present a cohort of 79 patients with a pathological finding in 21 of them. In the other patients the finding after the operation proved to be normal, i.e. the bed was free after the performed nephrectomy, retroperitoneal vessels were free and the line of m. psoas on the surgically treated side proved to be intact. Computer tomography can prove not only the relapse, but also metastatic affection of other organs, particularly in the liver and adrenals.

[Computer tomography of the kidneys after long-term dialysis].

In patients with chronic kidney failure in the long-term dialysis programme multiple minute cysts frequently develop in the shrunken kidneys. In addition to the cysts, in 20% of patients there are also multiple kidney tumours causing severe complications. In most cases the clinical picture of the disease is insignificant, hematuria being the most frequent manifestation. The authors present their cohort of 21 patients with irreversible kidney failure, who have been examined by computer tomography in the 1986-1987 years. The mean period of dialysis programme was 5.7 years, chronic glomerulonephritis and interstitial nephritis being the basic disease. The patient were, according to the results of computer tomography, divided into four groups: 1. the presence of cysts or tumours was not demonstrated, 2. multiple cysts were found in bilateral localization, 3. less than 3 cysts were found, 4. there was a kidney tumour. A factor causing the development of the cysts has not yet been identified. It is presumed that the disease is caused by a biologically active substance which is not efficiently dialyzed. On the basis of the present work the authors recommend the aimed examination of the kidneys in patients at the stage of chronic kidney insufficiency and particularly in patients subjected to dialysis for long period of time. The recommended examination is by computer tomography and the attention should be centered to possible occurrence of acquired cystic disease of kidney tumours.

Computed tomography of the spleen.

Computed tomography is a very useful method in the diagnosis of splenopathy--any anomalies, inflammatory, neoplastic as well as traumatic states of the spleen. Although these processes are not too frequent, their correct determination is an important part of radiodiagnosis. Computed tomography is so far the best method used for the identification of the congenital varieties of the spleen that may be mistaken, in another examination, for a pathological process of an adjacent organ. In the study a total of 185 pathological spleen findings was evaluated. These were obtained from the total of 18,960 CT examinations of the abdomen. The most frequent finding was splenomegaly (69.2%), less frequent were haematomas and splenic cysts (12.4%) and congenital varieties of the spleen (8.1%). Sporadically, splenic infarction (2.7%), thrombosis of the splenic vein (3.8%), tumour (2.2%) and splenic abscess (1.6%) were demonstrated.

[Examination of the injured spleen using computer tomography].

In blunt abdominal injury the most frequently injured organ is the spleen. A rapid and precise diagnosis of an injured spleen is therefore of great importance for early and correct therapeutic procedure. The authors present a group of 56 patients, who have been examined in the 1981-1987 years after blunt injuries of the belly by computer tomography. In 12 cases there was the diagnosis of subcapsular haematoma of the spleen, intraparenchymatous rupture was present in eight patients. In the remaining 36 cases the trauma of abdominal organs was not confirmed. All findings were verified by surgery or a control computer tomography and clinical examination of the patients. The authors demonstrate typical traumatic conditions. Computer tomography is a very useful method which enables a rapid, precise and non-invasive diagnosis of different degree of the spleen injury, its possible complications and differentiates these conditions from uninjured spleen. The authors present a brief survey of pictures of injured spleen in other methods of examination. In comparison with those methods, computer tomography is the most effective one, which provides a complex information of other organs of abdominal cavity. It also enables a considerate examination of patients severely injured and in non-cooperating ones.
