The utilization of cranial models created using rapid prototyping techniques in the development of models for navigation training

Waran V, Pancharatnam D, Thambinayagam HC, Raman R, Rathinam AK, Balakrishnan YK, et al.

J Neurol Surg A Cent Eur Neurosurg, 2014 Jan;75(1):12-5.

Navigation in neurosurgery has expanded rapidly; however, suitable models to train end users to use the myriad software and hardware that come with these systems are lacking. Utilizing three-dimensional (3D) industrial rapid prototyping processes, we have been able to create models using actual computed tomography (CT) data from patients with pathology and use these models to simulate a variety of commonly performed neurosurgical procedures with navigation systems.

Endoscopic fenestration at the splenial-habenular junctional area for symptomatic cavum and tumor at the foramen of Monro: case reports and anatomical review

Idris Z, Johnson JR, Abdullah JM

J. Neurosurg., 2015 Mar;122(3):504-10.

PMID: 25343181 DOI: 10.3171/2014.9.JNS132683

The splenial-habenular junctional area is an alternative site for neuroendoscopic fenestration to divert CSF flow into the quadrigeminal cistern in cases in which endoscopic third ventriculostomy is not amenable. In some patients with obstructive hydrocephalus, the splenium of the corpus callosum can be elevated from the habenular complex. This exposes the membranous connection between the splenium and habenula, which can be fenestrated to divert the CSF flow into the quadrigeminal cistern. This technique can be performed in patients in whom the foramen of Monro or the third ventricle is blocked by a lesion. Here, the authors present 3 complex cases that were managed by neuronavigation-guided transventricular transcavum endoscopic fenestration of the splenial-habenular junctional area. These cases may increase the knowledge and understanding of the anatomy of this region.

Neuronavigation-guided endoscopic management of a pineal region tumour with obscured floor of the third ventricle: case report

Idris Z, Ghani AR, Idris B, Muzaimi M, Awang S, Pal HK, et al.

Minim Invasive Neurosurg, 2011 Jun;54(3):125-7.

PMID: 21863520 DOI: 10.1055/s-0031-1277198

Shunt surgery is frequently chosen to manage periventricular metastasis of pineal region tumours which obscured the floor of the third ventricle. However, this procedure falls short due to distant metastasis. Neuronavigation-guided endoscopic surgery offers a viable alternative.

Bailouts During Neurointervention; Novel Techniques in Tackling Coil Migration and Premature Intravascular Detachment of Microcatheter Tip

Ambrosanio G, Arthimulam G, Leone G, Guarnieri G, Muto M, Muto M

World Neurosurg, 2020 10;142:167-170.

PMID: 32615295 DOI: 10.1016/j.wneu.2020.06.190

BACKGROUND: Intracranial vascular malformations are increasingly being treated via the endovascular route. Though generally safe, a multitude of intraprocedural complications that potentially lead to disastrous clinical outcomes may arise. It is crucial for the operators to be well versed with the various techniques that are available to overcome any procedure-specific complications.

METHODS: We present 2 cases in which we encountered premature intravascular detachment of the microcatheter tip and coil migration while treating a dural arteriovenous fistula and aneurysm, respectively. We used a stentriever to remove the detached microcatheter tip and suction using the reperfusion catheter to remove the migrated coil, both techniques that have not been reported in the literature thus far.

RESULTS: Detached microcatheter tip and migrated coil were successfully retrieved using a stentriever and aspiration catheter.

CONCLUSIONS: These novel techniques could potentially reduce mortality and morbidity associated with neurointervention.
