As an essential component of minimally invasive spine surgery, endoscopic spine surgery (ESS) has continuously evolved and has been accepted as a practical procedure by the worldwide spine community. Especially for lumbar disc herniation (LDH), the percutaneous endoscopic or full-endoscopic discectomy technique has been scientifically proven through randomized controlled trials and meta-analyses to be a good alternative to open discectomy. The initial concept of endoscopic spine discectomy was concerned with indirect disc decompression using various instruments such as blind forceps, a nucleotome, laser, radiofrequency coblation, and some chemical agents. ⋯ Furthermore, the medical applications of ESS is broadening to include spinal stenosis, segmental instability, infection, and even intradural lesions. In this review article, I describe the history of endoscopic spine discectomy and decompression techniques, as well as evolution of the paradigm. This history may help indicate the future of practical ESS.

The use of thrombectomy in the treatment for acute ischemic stroke (AIS) affecting the anterior circulation is well established. Comparatively, fewer data exist on the effectiveness of these techniques in treating posterior circulation occlusions. This review analyzes and reports on the usefulness and outcomes of emergent thrombectomy in large-vessel occlusions affecting the posterior circulation. ⋯ In patients with AIS caused by large-vessel occlusion of the posterior circulation, successful reperfusion can be achieved via EMT, with approximately a third of these patients achieving a good functional outcome. However, with similar proportions of treated patients experiencing significant morbidity or mortality, respectively, there is urgent need for additional studies to identify predictive or modifiable factors for a positive outcome.

With the evolution of endoscopic instruments and techniques, full-endoscopic spine surgery has attracted more attention worldwide in recent years. At the initial stage, surgeons conducted endoscopic lumbar discectomy using the transforaminal approach. Next, interlaminar endoscopic lumbar discectomy was developed to treat a herniation disc at the L5-S1 level. ⋯ However, the steep learning curve of endoscopic procedures has remained challenging. The use of interlaminar endoscopic lumbar discectomy entails many essential skills to manage the different anatomical structures of the spine. From the perspective of successful and safe interlaminar endoscopic lumbar discectomy, we have discussed the technical considerations for endoscopic procedures.

Raphael Acquaviva: the forgotten pioneer of modern neurosurgery in Morocco.
For the young generations, it is important to state the values that define and recognize the role of leaders and pioneers in neurosurgery, especially in developing countries. This subject seems often overlooked. In Morocco, the real birth of modern neurosurgery as an independent surgical specialty was undoubtedly made thanks to Doctor Raphael Acquaviva during the 1950s and 1960s, when he founded the first neurosurgical department in Casablanca. ⋯ Moreover, he was involved in medical publications and education in his host country. In this article, the author reviews Acquaviva's career trajectory in its historical context, highlighting its impact on modern neurosurgery in Morocco and abroad. This contribution could be a good start to collect information to preserve the national neurosurgical memory in many developing countries.

Transforaminal full endoscopic lumbar diskectomy (TELD) is a typical minimally invasive surgery, with the associated benefit of decreased possibility of anatomic structural injury, and is an effective alternative to open diskectomy. Among the various endoscopic spinal surgical techniques currently available, TELD is the most basic and traditional surgery that can be performed through the transforaminal route; it has been used for >30 years. Recently, with the advancements in surgical techniques, TELD has been successfully performed for patients with lumbar disk herniation of different types. ⋯ The second step is to determine a safe and easily accessible entry point and then landing and docking the working sleeve as close to the target as possible without causing exiting nerve root injury. The third step is complete decompression of the symptomatic nerve with free mobilization of the neural tissue. The final step involves performing foraminoplasty using an advanced technique to overcome the limitations associated with TELD in difficult cases.
