[CMV-enterocolitis as a cause for repeated intestinal intussusceptions in an adult patient after liver transplantation?]. / CMV-Enterokolitis bei einer erwachsenen lebertransplantierten Patientin als Ursache rezidivierender Invaginationen?

Intestinal intussusception in the adult is often idiopathic but also known to be associated with chronic inflammatory bowel disease, coeliac disease, tumours or previous abdominal operations. A 22-year-old women after liver transplantation due to Crigler Najar Syndrome suffered from repeated episodes of abdominal pain. The diagnosis of repeated self-limited intestinal intussusceptions was made by computed tomography and ultrasonography. A laparoscopy revealed no cause for the intussusceptions. During a new episode of abdominal pain caused again by an intussusception a colonoscopy was performed that showed aspects of a discreet colitis. In the biopsies CMV was detected by qualitative PCR, while blood tests for CMV pp65 antigen were negative. A therapy with gancyclovir was initiated which lead to remission of the patient's symptoms. A colonoscopy six weeks later showed a completely normal colon, while in the biopsies CMV was not detectable. After a follow-up of one year the patient has not suffered from any further episodes. This case demonstrates the role of chronic intestinal CMV infection as a possible causative factor for repeated intussusceptions in immunosuppressed patients. Whenever possible a PCR for CMV in colon biopsies should be carried out to detect an intestinal CMV infection because as shown in our case results for immunohistopathology and CMV pp65 can be negative despite a chronic infection.

[Loco-regional lysis with thrombosis older than 10 days: experiences and outcome]. / Erfahrungen mit der lokoregionalen Fibrinolysetherapie bei Thrombosealter über 10 Tage.

Successful treatment of deep vein thrombosis by lysis therapy leads to recanalisation of the occluded vessel saving the venous flaps, thus limiting postthrombotic syndrome. Systemic lysis therapy carries an increased risk of fatal complications (1-2%). However, loco-regional lysis therapy with rtPA stands out as a method of recanalisation without increased complications compared to compression and anticoagulation therapy. According to the leading opinion about systemic lysis therapy it should only be performed if thrombotic age does not exceed 10 days. In this study we examined whether loco-regional lysis therapy is successful with older thrombosis, too. We showed that in thromboses older than 10 days lysis success was slightly decreased whereas postthrombotic syndrome doubled (up to 50%). These results point out loco-regional lysis as a method suitable for thromboses with age up to 10 days only.
