Inflation-deflation method for endoscopic evacuation of intracerebral haematoma

Endoscopic evacuation of intracerebral haematoma (ICH) has the advantage of being less invasive than craniotomy, but limited visualisation and difficulties in haemostasis are still a concern. The collapse of the haematoma cavity limits the visualisation of the surgical field. Inflation of the haematoma cavity with saline irrigation improves visualisation and facilitates accurate intra-operative orientation.

A unique technique, the cavity inflation-deflation method can help in exploring the residual haematoma and accessing the bleeding points. We also developed a combined irrigation-coagulation suction tube that concentrates the capabilities of suction, irrigation and monopolar coagulation.

The use of this multifunctional dedicated instrument and its application in the cavity inflation-deflation method allows for easy identification of residual haematoma and bleeding vessels. Secure haemostasis can also be accomplished under clear visualisation. No surgical complications and rebleeding occurred in any patient following the procedure. Our results show that the median haematoma evacuation rate was 99% and the surgical outcome was satisfactory.

The inflation-deflation method using a combined irrigation-coagulation suction tube can facilitate optimal evacuation of ICH with secure haemostasis. Although further accumulation of patients and careful analyses are needed to be known whether this procedure improves the clinical outcomes in the patients, the preliminary results of its application have been promising.
