A novel approach to the treatment of ascites associated with ovarian hyperstimulation syndrome

Ascites is a clinical manifestation of severe ovarian hyperstimulation syndrome (OHSS) which may complicate the induction of ovulation using exogenous gonadotrophins. In severe OHSS severe ascites may occur and can lead to dyspnoea, abdominal discomfort and oliguria, To relieve ascites paracentesis is performed two to three times weekly as needed. We report three cases where an indwelling peritoneal catheter was used to decrease the need for repeated paracentesis. Under ultrasound guidance a closed system Dawson-Mueller catheter with 'simp-loc' locking design was inserted to allow continuous drainage of the ascitic fluid. A total of 23 I of the ascitic fluid were drained from the first, 20 I from the second and 28 I from the third patient with significant decrease in abdominal discomfort and improvement in the urine output. No complications or adverse reactions were noted, Continuous drainage of the ascitic fluid is efficient, It quickly decreases the abdominal discomfort, improves the urine output and prevents the need for multiple abdominal paracenteses which some patients may require.
