Stroke is a leading cause of disability and mortality worldwide. Related research, although already providing significant insights regarding the underlying pathophysiology and potential treatment strategies, has been far from conclusive. Stroke models have been proved of extreme significance for laboratories around the world. In the present report, we have described in detail the most popular to date focal stroke model, the transient intraluminal filament middle cerebral artery occlusion (tifMCAO) model in rats. This model reliably mimics stroke in humans and also approximates endovascular thrombectomy. The tifMCAO model was performed using Wistar rats weighing 300-400 g. We have described the surgical technique in a stepwise manner, with figures and/or high-definition video provided for each step. We have also introduced the use of complete arteriotomy of the external carotid artery stump during the procedure. We performed tifMCAO in 65 rats (male and female) involved in various experimental protocols. Although the initial mortality was 48%, practice reduced the rate to 10%. The mean procedural time was 53 minutes (range, 38-85 minutes). In a group of 8 rats ischemia was confirmed in 7 of them, with the stroke induction rate being 87.5%. The tifMCAO stroke model in rats is the most often used experimental model of focal ischemia because of its clinical relevance. We revisited the procedure and divided it, for instructional purposes, into 15 consecutive and distinct steps.

Background: Nowadays, Anterior Cervical Discectomy and Fusion (ACDF) is considered a routine procedure. However, unexpected difficulties do occasionally arise, especially when anterior neck pathologies or anatomical variations are encountered. In such cases, proactive thinking will allow surgeons to tailor appropriately their approach and eliminate surgical risks. Case presentation: We present the case of a 50-year-old male patient suffering from left upper limb radiculopathy that underwent a C7-T1 ACDF combined with a hemithyroidectomy. Excision of the right thyroid lobe was offered to the patient because of a goiter found during the preoperative work-up. Furthermore, the hemithyroidectomy provided a wide surgical field so the ACDF performed without excreting excessive traction to the adjacent neck structures. Conclusions: The patient had an uncomplicated post-operative. To our knowledge this is the first report of a planned hemithyroidectomy being carried out as the first step towards an ACDF procedure.
