A Direct Aspiration First Pass Technique is one of the most widely used techniques in mechanical thrombectomy. Aspiration catheter size plays a major role in the success of this technique. The AXS Vecta (Stryker Neurovascular, Fremont, California, USA) aspiration catheter is the first approved 0.071-inch catheter for mechanical thrombectomy. Here, we report our initial experience with direct aspiration thrombectomy using the AXS Vecta aspiration catheter. ⋯ In this early experience with the new AXS Vecta aspiration catheter, the catheter was safely navigated to the target vessel even at the level of M2 segment.

Different treatment options have been proposed for aneurysmal bone cysts (ABCs) with sclerotherapy favored as primary treatment and surgery remaining the mainstay of treatment in case of compression of neural structures. Recurrent spinal ABCs are burdened by increased risk of spinal deformity and instability, further complicating the management of these cases. ⋯ Percutaneous sclerotherapy with hydroxyapatite cement proved to be highly effective and safe in the treatment of spinal ABC, though surgery remains mandatory in case of spinal cord compression. The main advantage of sclerotherapy with hydroxyapatite cement seems to be the capacity to regenerate bone with normal radiologic features.

To compare the effectiveness of radiofrequency neurotomy (RN) and endoscopic neurotomy (EN) of lumbar medial branch (MB) for facetogenic chronic low back pain (FCLBP). ⋯ For FCLBP, EN and X-ray-assisted RN of lumbar MB are both effective treatments. However, endoscopic lumbar MB neurotomy has the better and longer effectiveness.

To analyze the biomechanical changes of lumbar adjacent segment by comparing the biomechanics after the surgery of transforaminal lumbar interbody fusion (TLIF) and oblique lumbar interbody fusion (OLIF). ⋯ The biomechanical analysis showed that both TLIF and OLIF can increase ROM and IDP. It indicates that TLIF and OLIF probably increase the potential risk of adjacent segment degeneration similarly.

To investigate effectiveness of brace treatment in patients with adolescent idiopathic scoliosis with curve between 40° and 45° and to determine predictive factors associated with bracing outcome. ⋯ Bracing may produce a favorable outcome in certain patients with curve between 40° and 45°. It should be cautiously used in this situation, as there was a higher probability of bracing failure. It is important to differentiate patients at high risk of curve progression at an early stage to avoid overtreatment.
