Imaging work-up for peritoneal access care and peritoneal dialysis complications.

Peritoneal dialysis (PD) represents a treatment opportunity for patients with end-stage renal failure, but it has particular complications that sometimes force cessation of this procedure (1- 9). These complications are due to the presence of the peritoneal catheter and of dialysis solution within the peritoneal cavity. Infections are the most common complications of PD, followed by mechanical complications. Diagnostic imaging of the complications of PD is important because such an evaluation can aid in the diagnosis and in the decision making process about the treatment. In this review we present the main radiologic investigations employed: plain radiograph, US, peritoneography, computed tomography peritoneography, magnetic resonance peritoneography, peritoneal scintigraphy. To diagnose catheter-related problems plain radiograph, ultrasonography and peritoneography can be useful. US is useful in diagnosing and following-up exit-site and tunnel infections. Peritoneography and CT-peritoneography, alone or in combination, can be recommended as gold standard investigation to assess mechanical peritoneal dialysis complications, such as catheter malfunction, leaks, hernias and sclerosing peritonitis. Newer methods, such as MR peritoneography or scintigraphy could be useful in selected patients, on center-based experience. An appropriate use of radiology may significantly improve technique survival, morbidity and mortality of patients treated with PD.

Hemoperitoneum in a continuous ambulatory peritoneal dialysis patient caused by a hepatocarcinoma treated with percutaneous embolization.

Hemoperitoneum is an infrequent but normally benign complication in continuous ambulatory peritoneal dialysis (CAPD) patients. It can occur at any time during peritoneal dialytic treatment. Hemoperitoneum is not associated with a specific disease and usually disappears spontaneously. In 20% of cases, however, hemoperitoneum is severe and requires specific investigation and emergency therapy. We report a case of hemoperitoneum in a 70-year-old, anti-hepatitic C virus-positive woman. After 48 months of CAPD treatment, a bloody peritoneal effluent developed, with severe anemia (hematocrit decreased from 30% to 20%). An abdominal computed tomography scan showed three hepatic lesions with signs of hepatic neoplasms; selective hepatic arteriography confirmed the diagnosis. Chemoembolization of the three lesions was performed, and hemoperitoneum disappeared within a few hours.

[Computer-assisted reporting. Experience with the use of a departmental information system].

Since April 1989, a departmental information system has been working at the Radiology Dept. of Desio Hospital, Desio, Milan. The system has six work-stations, connected in a local network. The Proram program (Metrika, Verona) is employed, which allows the computerized management of departmental activities. After a short description of Proram's functions and of their advantages, a special attention is paid to the reporting activity, as limited to normal reports. The latter can be made either as free or as codified and previously stored texts. The percentage of use of codified reports (49%) is evaluated on the basis of about 8,000 X-ray exams per year. Through the analysis of percentage data of codified reports, according to exam categories, previously stored reports appeared to be more frequent for inpatients and for emergency examinations (58% of overall figure). Codified reporting appeared to be proportionally less employed in the most specialized diagnostic examinations. On the whole, considerable time was saved, and the number of misprints decreased; moreover, higher language standardization was achieved. More detailed information was thus available for the clinician.

[Contribution of peritoneography combined with computerized tomography, in the assessment of abdominal complications in patients undergoing continuous peritoneal dialysis].

Continuous ambulatory peritoneal dialysis (CAPD) is a generally well-tolerated treatment. However, some patients exhibit such complications as to prevent the continuation of treatment. Peritonitis is the major problem, but the continuation of treatment may also be undermined by different complications, such as peritoneal leakage, hernia, catheter malfunctioning, and scrotal-penile edema; a careful investigation of the patient is always needed in such cases. From November 1985 to February 1990, we examined 20 patients, who had presented with different types of complications in the course of dialysis. Peritoneography demonstrated 3 cases of abdominal hernias, 2 cases of patency of the peritoneal-vaginal duct, and 2 cases of catheter obstruction. Peritoneal CT allowed the identification of leakage in 3 patients, while the combined use of the two techniques showed adhesions or pathologic peritoneal recesses in 7 cases. In 3 patients normal patterns were observed. Peritoneography, especially if combined with CT, can carry out a double function, that is in both the screening and choice of the subjects to destine to peritoneal dialysis, and in therapeutics, to evaluate complications. Moreover, the technique is extremely reliable thanks to both its simple execution and lack of disadvantages.

[Quantitative analysis of bone tissue. Correlation of several radio-morphometric indices with gamma-absorptiometric mineralometry].

According to results of experimental study on 70 women, either normal or osteoporotic, the authors come to a critical valuation of known radio-morphometric index concerning the measure of amount of bone and propose the cortical planimetric percent area of the second right hand metacarpal as original radio-morphometric index, greatly correlated (r = 0,879) to gamma-absorptsiometric mineralometry.

Cutaneous seeding after ultrasound-guided percutaneous ethanol injection for treatment of hepatocellular carcinoma.

Cutaneous seeding is a rare complication of interventional ultrasound procedures. We describe a case of needle-track cutaneous seeding of hepatocellular carcinoma (HCC) after sonographically guided percutaneous ethanol injection (PEI). In our case, the seeding might have been related to the type of needle used and the multiple passes required to treat the liver lesion. Despite the risk of needle-track seeding, PEI remains useful in the treatment of HCC.

MR imaging of anterior cruciate ligament repair.

Magnetic resonance (MR) imaging is an accurate means of analyzing disruptions of the native anterior cruciate ligament (ACL). Various techniques may be used to repair a disrupted ACL. A common repair is the MacIntosh lateral-substitution over-the-top repair in which a strip of fascia lata from the iliotibial band is used as a "neoligament." The results of 27 MR examinations of 17 athletes with this repair were analyzed to determine the appearance of the neoligament on MR. Thirteen of the 17 patients had returned to full athletic activity and four were capable of strenuous activity. Examinations were made at both 0.5 and 1.5 T in varied extents of external rotation from 0 to 20 degrees, and at variable time intervals after surgery from 1 to nearly 40 months. Only two patients clinically required postrepair arthroscopy, but both had normal repairs. Neoligaments were classified as well-defined (n = 6 studies), ill-defined (n = 10), and not discernible (n = 11), based on clarity of appearance. Reasons for this variable appearance include the variable presence of fibrous and fatty tissue investing the neoligament. We conclude that the normal neoligament, unlike the normal active ACL, has a variable appearance, including nonvisualization on MR and that criteria used in evaluating the native ligament will be inadequate to assess the repair.

[Treatment of diaphyseal pseudoarthrosis with transosseous osteosynthesis by the Ilizarov method. Radiographic signs of reparative osteogenesis].

The main phases of ossification are shown-based on the results achieved by re-examining the X-ray pictures of 14 patients affected by tubular bones pseudoarthrosis treated with Ilizarov's closed compression-distraction osteosynthesis. The roentgen signs in particular are examined which are considered as expressive of positive evolution of the pseudoarthrosis. An outline of X-ray evolution of nonunions is also proposed, referring to the peculiar biological characters of ossification under compression-distraction stimulation.
