[Intestinal contrasting in abdominal computed tomography].

In 56 patients undergoing abdominal CT the gastrointestinal tract was defined by negative contrast instead of the conventional positive contrast from an iodine containing contrast medium. The contrast material was a 2 1/2% mannitol solution and was used for filling the rectum. Filling of the gastrointestinal tract was of similar quality to that obtained with positive contrast media. The number of artifacts due to high contrast boundaries was slightly greater with the negative contrast than it would have been with positive contrast. Differentiation of the gastrointestinal tract from other abdominal organs was equally good for both methods. The negative contrast method was poor in diagnosing cystic tumours but proved much better than positive contrast for evaluating the wall of the gastrointestinal tract.

[MR tomography of cystosarcoma phylloides. A case report].

This is the first time a report is being published in medical literature on the MR imaging of a cystosarcoma phylloides tumour after intravenous contrast agent administration. MR tomography enabled complete visualisation of the tumour even in the region close to the thoracic wall, as well as clear delineation against the non-tumorous glandular tissue. This means that the limits along which complete extirpation of the tumour could be performed, were determined accurately before the operation, such complete removal being imperative to avoid tumour recurrence.

[Chemical burns caused by hydrofluoric acid. Incidence, frequency and current status of therapy].

Reasons and frequencies of hydrofluoric acid burns have been investigated during our work in the toxicological information centre (1987/88) and by means of the patients treated in the last five years in our ICU: Almost all of the cases are due to accidental hurts (29/30). About 3/4 of the accidents (22/30) happened during occupational exposure. One third of the patients (10/30) have been exposed to hydrofluoric acid fume and 18/30 suffered from percutaneous burns especially of the distal parts of the upper limbs. Oral intoxications are rare (2/30). The observed quotes of the information centre are equivalent to those of our own patients (eight cases from 1984 to 1989). Hydrofluoric acid burns are treated with calcium. Concerning the frequent burns of the limbs, the intraarterial therapy proved good and prevailed during the last years over the classical infiltration therapy. Only early treatment avoids necroses. Unfortunately the particularity of this percutaneous intoxication is often misunderstood.

[The feasibility of magnetic resonance tomography in the diagnosis of non-palpable breast tumors].

This study deals with the role of MRI in elucidating clinically silent lesions of the breast with indeterminate changes on mammography. MRI localisation of suspected lesions was possible in all cases by using double coils after contrast enhancement of the glandular tissue, independent of the findings on mammography. Inability to demonstrate micro-calcification did not prove a disadvantage. MRI cannot provide a definite tissue diagnosis, since there is overlap between the appearances of malignant and benign lesions.

[Intestinal contrast imaging in abdominal computed tomography: water or contrast medium?].

The suitability of water as an oral or rectal contrast medium for abdominal CT was studied in 56 patients and compared with an iodine-containing water-soluble contrast medium (ioxital amino acid). In some cases it was impossible to differentiate gastrointestinal structures from extraluminal fluid collections (cystic tumours, ascites, abscesses) and there was poor filling of distal small bowel and colon. The routine use of water can, therefore, not be recommended. In some cases, however, water can result in improved image quality by reducing artifacts and improving the demonstration of the mucosa.

[Acute emphysematous cholecystitis as a cause of pneumoperitoneum].

A 48-year-old man developed progressively more severe epigastric pain, pain on pressure in the right upper abdomen and fever up to 38.6 degrees C so that acute cholecystitis was suspected. Ultrasound did not demonstrate a gall-bladder but a sickle shaped, dense echo with a distal adjoining echo-free zone. Computed tomography revealed air in the gall-bladder lumen as well as intramural and pericholecystic air pockets, findings pathognomonic for emphysematous cholecystitis. In addition pneumoperitoneum was diagnosed. Subsequent cholecystectomy intraoperatively revealed a gangrenous, nonperforating gall-bladder in which E. coli was demonstrated. During the first postoperative week, there were no complications under transitory antibiotic treatment with tobramycin and ticarcillin with clavulanic acid. Then, an abscess developed in the residual gall bladder bed; this abscess was cured after drainage, local irrigation and re-initiation of antibiotic treatment. The patient was finally discharged well.

Detection of dissection of the aortic intima and media after angioplasty of coarctation of the aorta. An angiographic, computer tomographic, and echocardiographic comparative study.

Balloon coarctation angioplasty (BCA) was performed in eight patients (five male and three female) who were 14-49 years old (mean, 27.3 years) with isolated discrete unoperated coarctation of the aorta (n = 7) and postoperative recoarctation (n = 1). BCA was successful in seven of eight patients, resulting in a decrease in the gradient (64 +/- 19 to 16 +/- 13 mm Hg, p less than 0.01), an increase in the diameter at the coarctation site (0.9 +/- 0.4 to 1.6 +/- 0.4 mm, p less than 0.01). Follow-up (6 months) has demonstrated continued gradient relief (6 +/- 9 mm Hg) and diameter increase (1.6 +/- 0.2 cm). Monitoring was performed by transesophageal echocardiography (TEE) during BCA, and before and after BCA angiography and after BCA computed tomography. In three of seven patients, immediately distal to the BCA site, intimal flaps (1-2 cm) could be detected by TEE but not by angiography or computed tomography. Follow-up TEE showed spontaneous healing in two and persistence in one patient. By TEE and computed tomography in one of eight patients during follow-up, intima and media dissection was found with pleural effusion and spontaneous healing. In one female patient, aortic dissection occurred after successful uneventful BCA, detected by TEE at the 6-month follow-up study and subsequently confirmed by biplane angiography, not detected by computed tomography and previous monoplane angiography. Because of the significant morbidity of BCA in this group of patients, its role in the management of adults with coarctation has yet to be determined. Further long-term follow-up studies will demonstrate whether the observed intima and media dissection by TEE after BCA are related to aneurysm formation.

[Local fibrinolytic therapy of vascular occlusions in the pelvic-leg area and the upper extremity].

Seventy-three patients with vascular occlusions in the pelvis or lower limbs and three patients with upper limb lesions were treated by local low dose fibrinolysin, with strict control of any possible bleeding tendencies. Adequate recanalisation was obtained in 56 patients (73.6%). In ten patients, the occlusion recurred while the patient was still in hospital. After four to six months, 37 of the 56 (67%) of the vessels were still patent. In 18 patients, peripheral emboli resulted in some deterioration, but in 15 of these cases this could be treated successfully by operation. The methods and indications of local fibrinolysis therapy and the problems associated with it are discussed.

[Lipohaemarthrosis (author's transl)].

Besides the presence of blood in an injured joint, fat-containing blood can also be found in the joint with intra-articular fractures. This condition, which can be demonstrated by x-ray film, is known as lipohaemarthrosis. We found this to be the case in 8 out of 295 patients with shoulder dislocation. The origin, significance and differential diagnosis of this condition are described.
