Abstract
Endoscopic Port Surgery for Paraventricular Brain Metastases Using an Inexpensive Device
Highlights
IntroductionIntraventricular and periventricular tumors have conventionally been resected through transcortical routes, habitually requiring the use of brain retractors which consist in various types of spatulas to keep the surgical corridor and ensured the microsurgical resection
In suitably selected patients with brain metastases, Endoscopic Port Surgery offers a viable option to achieve the goals of tumor surgery with low morbidity and fast recovery
The modified 20-ml syringe can be used as a transparent tubular retractor and it is simple, lightweight, inexpensive and effective
Summary
Intraventricular and periventricular tumors have conventionally been resected through transcortical routes, habitually requiring the use of brain retractors which consist in various types of spatulas to keep the surgical corridor and ensured the microsurgical resection This technique does not apply distributed pressure and complications as vascular damage, brain edema, seizures and focal neurological deficits are not uncommon [1,2,3,4]. To solve this problem a number of tubular retraction systems have been developed with distributed pressure which are combined with an endoscopic visualization method to ensure better surgical field illumination and angular vision [5,6,7,8,9,10,11,12,13,14]. We describe the results of this alternative method with some technical variations in six patients with deep brain metastases and discuss the technical aspects
