Ultrastructural observation of filtration membrane in cell-free and concentrated ascites reinfusion therapy for malignant ascites.INTRODUCTION
 To clarify the precise mechanism of filter clogging, we performed an ultrastructural observation study of the filtration membrane after the filtration of malignant ascites.



Ultrastructural observation
Cell-free and concentrated ascites reinfusion therapy (CART) is used for the treatment of diuretic-resistant ascites.  An increase in circuit pressure and clogging of the filtration membrane often occur in CART for malignant ascites.


 Our results suggest that the specific pathophysiologies of malignancy (such as inflammation or coagulation/fibrinolysis) and characteristics of malignant ascites (highly concentrated and cell-rich) are associated with clogging of the filtration membrane during CART.
