Safety and efficacy of mini doppler in recurrent pituitary tumours: Report of 12 cases

Abstract

Background: Pituitary surgery is the most common surgery used to remove pituitary tumours. The use of mini doppler in surgical removal of an endonasal pituitary tumour has shown good short-term clinical outcomes and few complications in patients. Cavernous sinus invasion limits the surgical excision and still a challenge of gross total resection.  

Objective: The main objective of this study is to evaluate the outcome of surgical removal of an endonasal pituitary tumour using mini doppler.   

Method: A total of 12 patients were studied retrospectively from 2012 to 2018 in a single institution (Private hospital) in Dhaka, Bangladesh. The male and female ratio was 7:5.

Results: 92% of cases of the total number of patients had satisfactory removal/ neurological improvement/hormonal improvement. Among 12 cases, 8 cases had transient diabetes insipidus and one patient had CSF leak.   

Conclusion: The intraoperative Doppler is a useful tool to localize the carotids, which provides safer resection of endonasal pituitary tumours. Thus, it is very safe and effective for laterosellar resection of recurrent pituitary tumours and for cavernous sinus invasions.
