Occurrence of spontaneous fistulas detected by contrast filling during computed tomography-guided percutaneous drainage placement of splenic and perisplenic fluid collections.

Spontaneous fistulas detected during CTGDP of splenic or perisplenic fluid collections are common. Post-interventional contrast filling of the drain drastically improves the detection rate of perisplenic, peripancreatic and perihepatic fistulas simultaneously initiating appropriate follow-up interventions.
