A new catheter for subduro-peritoneal shunting

Subduro-peritoneal (SP) shunting is one of the definitive treatment modalities in the management of chronic subdural collections. Different shunt types have been used in SP shunting. An effective and inexpensive catheter has been designed for SP shunting. This new catheter does not have a valve system. The proximal end of the catheter has a right angle after the first 5 cm. The distal end of the catheter is open and has no slits. The proximal right angle tip of the subdural tubing is inserted 5 cm. Fourteen patients with symptomatic subdural fluid collection were treated with SP shunting using this shunt tube. Resolution of the subdural fluid collection took between 2 and 14 weeks. The SP shunt was easily removed in 4 patients. No complications occurred. Follow-up of the patients ranged from 3 to 12 months. This new catheter seems to be effective in the drainage of subdural fluid collections.
