“…Furthermore, the biopsy procedure is easy to perform, and it requires only 2 people. The surgeon does not need intensive training, like that needed for other biopsy systems, before using this stereotactic device . However, the construction of the biopsy frame itself based on the MR images should be performed by a specifically trained person.…”

Background Brain biopsy of intracranial lesions is often necessary to determine specific therapy. The cost of the currently used stereotactic rigid frame and optical tracking systems for brain biopsy in dogs is often prohibitive or accuracy is not sufficient for all types of lesion. Objectives To evaluate the application accuracy of an inexpensive magnetic resonance imaging‐based personalized, 3D printed brain biopsy device. Animals Twenty‐two dog heads from cadavers were separated into 2 groups according to body weight (<15 kg, >20 kg). Methods Experimental study. Two target points in each cadaver head were used (target point 1: caudate nucleus, target point 2: piriform lobe). Comparison between groups was performed using the independent Student's t test or the nonparametric Mann‐Whitney U Test. Results The total median target point deviation was 0.83 mm (range 0.09‐2.76 mm). The separate median target point deviations for target points 1 and 2 in all dogs were 0.57 mm (range: 0.09‐1.25 mm) and 0.85 mm (range: 0.14‐2.76 mm), respectively. Conclusion and Clinical Importance This magnetic resonance imaging‐based 3D printed stereotactic brain biopsy device achieved an application accuracy that was better than the accuracy of most brain biopsy systems that are currently used in veterinary medicine. The device can be applied to every size and shape of skull and allows precise positioning of brain biopsy needles in dogs.

“…Kopf's equipment is only approved for use in research tests [5] and not clinical use which may affect the precision standards it is held to. Though the time required to perform a biopsy may be affected by instrument adaptations, it can also be in luenced by user experience [18,19]. Squires et al [16] only took 19 minutes to complete the biopsy.…”

“…Only histopathological exams can identify the nature of the lesion seen in image studies [2]. Brain tissue biopsies are delicate procedures and different methods have been proposed: free-hand [6][7][8][9], ultrasound-guided [10] and, more recently, with the aid of stereotactic [11][12][13][14][15][16][17][18][19] and neuronavigational devices [20][21][22].…”

Objective:To perform a review of brain biopsies in the canine species and determine if it is possible to compare the stereotactic and neuronavigation results. Method:A search was performed in NCBI's PubMed database for stereotactic or neuronavigational canine brain biopsy publications and articles which met at least one of the inclusion criteria and not any of the exclusion criteria were selected. The inclusion criteria were: 1) assessment of the specifi city of the biopsy, 2) assessment of system accuracy, 3) assessment of the biopsy results, and 4) duration of the procedure. Results:Only one article met all the inclusion criteria. Eleven articles that partially met the criteria were used for comparison. Authors used different stereotaxic methods and two used neuronavigation equipment. The authors of the stereotactic studies either adapted devices from human medicine or developed their own devices; the level of accuracy was variable (errors of 0.0 mm to 5.1 mm), and the two articles that used animals with spontaneous lesions had a diagnostic specifi city rate higher than 90 percent. The accuracy of the neuronavigation studies was approximately 3.3 mm; however, no live animals were used. Conclusions:It was not possible to properly compare stereotactic and neuronavigation techniques. To do so, the methodologies and the assessed parameters need to be standardized.

“…Although most surgical models have been aimed at veterinary students, a few (besides the minimally invasive surgical models) have been designed with the resident or clinician in mind. One such model was the agarose and cheese canine skull model described by Sidhu et al to teach veterinarians how to perform stereotastic computed tomography‐guided brain biopsies 74 . Another model directed at veterinarians was the feline urogenital model described by Phillips et al to teach microvascular suturing 42 …”

Surgical skills are learned through deliberate practice, and veterinary educators are increasingly turning to models for teaching and assessing surgical skills. This review article sought to compile and review the literature specific to veterinary surgical skills models, and to discuss the themes of fidelity, educational outcomes, and validity evidence. Several literature searches using broad terms such as “veterinary surgery model,” “veterinary surgical model,” and “veterinary surgical simulator” were performed using PubMed, CAB abstracts, and Google scholar. All articles describing a model created and utilized for veterinary surgical training were included. Other review articles were used as a source for additional models. Commercially available models were found using review articles, internet browser searches, and communication with veterinary clinical skills educators. There has been an explosion of growth in the variety of small animal surgical task trainers published in the last several decades. These models teach orthopedic surgery, ligation and suturing, open celiotomy and abdominal surgery, sterilization surgeries, and minimally invasive surgeries. Some models were published with accompanying rubrics for learner assessment; these rubrics have been noted where present. Research in veterinary surgical models is expanding and becoming an area of focus for academic institutions. However, there is room for growth in the collection of validity evidence and in development of models for teaching large animal surgery, training surgical residents, and providing continuing education to practitioners. This review can assist with evaluation of current surgical models and trends, and provide a platform for additional studies and development of best practices.
