“…Ideal guidelines for the acquisition of CT images were evaluated and determined that the acquired images should have a thickness of 2 mm, and this data was adapted for the creation of 3D models. 29,30 However, with the advances in CT and 3D printer technologies, the acquired images have thinner slices (0.6 mm), as presented elsewhere by one of the authors (Leal A. G.) of the present article, 17 and can generate models with more details and precision.…”

“…3 The term "rapid" associated to those processes is relative, since the construction of some prototypes can take from 2 to 72 hours, depending on the size and complexity of the object. [15][16][17] A specific software that consists of the interface between the 3D model (CAD) and the AM machine decomposes the CAD model into several thin layers, which are piled one by one. The process of AM combines layers of material with the purpose of creating a solid object.…”

“…4). 17 It is known that one of the main difficulties during the microsurgical treatment of IAs consists in the appropriate choice of the clip to be used, due to anatomical variabilities and to the peculiarities of each aneurysm. It is also common knowledge that IAs present wide and/or complex necks and that surgical planning is essential 38 to avoid excessive manipulation of the intracranial vessels and an extended surgical time, which are factors that can predispose to intraoperative aneurismatic rupture.…”

“…In this context, the use of biomodels is only possible in elective cases, and their use in emergencies remains very restricted. 16,17 Only one paper described the use of emergency 3D printing in neurosurgery. The authors developed a method to produce solid models of cerebral aneurysms, with a shorter time of impression than those of the conventional methods, using a compact 3D printer with acrylonitrilebutadiene-styrene (ABS) resin.…”

Introduction Three-dimensional (3D) printing technologies provide a practical and anatomical way to reproduce precise tailored-made models of the patients and of the diseases. Those models can allow surgical planning, besides training and surgical simulation in the treatment of neurosurgical diseases. Objective The aim of the present article is to review the scenario of the development of different types of available 3D printing technologies, the processes involved in the creation of biomodels, and the application of those advances in the neurosurgical field. Methods We searched for papers that addressed the clinical application of 3D printing in neurosurgery on the PubMed, Ebsco, Web of Science, Scopus, and Science Direct databases. All papers related to the use of any additive manufacturing technique were included in the present study. Results Studies involving 3D printing in neurosurgery are concentrated on three main areas: (1) creation of anatomical tailored-made models for planning and training; (2) development of devices and materials for the treatment of neurosurgical diseases, and (3) biological implants for tissues engineering. Biomodels are extremely useful in several branches of neurosurgery, and their use in spinal, cerebrovascular, endovascular, neuro-oncological, neuropediatric, and functional surgeries can be highlighted. Conclusions Three-dimensional printing technologies are an exclusive way for direct replication of specific pathologies of the patient. It can identify the anatomical variation and provide a way for rapid construction of training models, allowing the medical resident and the experienced neurosurgeon to practice the surgical steps before the operation.

Additive Manufacturing of 3D Biomodels as Adjuvant in Intracranial Aneurysm Clipping

2018

One of the main difficulties in intracranial aneurysms (IA) surgery refers to the choice of the appropriate clip(s) to be implanted. Although the imaging exams currently available ensure visualization of IA's morphology, they do not bring an accurate reference positioning for the surgeon in executing the surgery procedure nor efficiently contribute to planning the surgery. Unfortunately, for IA's largely inaccessible regions, there is not an efficient method of treatment planning. Therefore, we propose a novel method that allows the generation of a 3D biomodel of the IA region under investigation using additive manufacturing technology (AM). Thus, a physical copy of the IA is produced and offers the surgeon a full view of the anatomy of that region of the brain. The aim of this study is the creation of a flexible 3D physical model (elastomer) through the AM technique, in order to allow the clip selection prior to the surgery. DICOM angio‐CT images from eight patients who underwent IA surgery were transformed into STL format and then built on a 3D printer. Preoperative surgical clip selection was performed and then compared with those used in surgery. At the end of the study, all 3D IA biomodels were reproduced for microsurgical clipping selection and it was possible to predict the metal clip to be used in the surgery. In addition, the proposed methodology helps to clarify the surgical anatomy and to avoid excessive manipulation of the intracranial arteries and prolonged surgical time. The major advantage of this technology is that the surgeon can closely study complex cerebrovascular anatomy from any perspective using realistic 3D biomodels, which can be handheld, allowing simulation of intraoperative situations and anticipation of surgical challenges.
