Review Comparative Study
Mechanical Thrombectomy with Intraoperative Local Thrombolysis Versus Mechanical Thrombectomy with Continuous Thrombolysis for Treatment of Cerebral Venous Sinus Thrombosis: A Systematic Review of 82 Cases.
The first-line treatment of cerebral venous sinus thrombosis (CVST) is systemic anticoagulation. However, patients with severe or a clinically worsening condition might benefit from mechanical thrombectomy (MT) combined with intraoperative thrombolysis (IOT) or MT with continuous thrombolytic infusion (CTI). The present study compared the efficacy and safety of these 2 endovascular therapeutic methods by performing a systematic review of the literature. ⋯ The results from our review suggest that MT with local thrombolysis is relatively safe, with no significant differences in efficacy and safety between MT+IOT alone and MT+CTI/MT+IOT+CTI. However, randomized controlled studies are required to provide a definitive answer on its use for CVST.

This study aims to evaluate the outcomes of Gamma Knife stereotactic radiosurgery (SRS) for dural arteriovenous fistulas (dAVFs) in older patients (≥65 years) compared with younger patients (age <65 years). ⋯ SRS achieves obliteration in most older patients with dAVF, with an acceptable rate of complication. There was no increased risk of postradiosurgery complications in the older cohort compared with the younger patients.

To evaluate the results of percutaneous endoscopic transforaminal diskectomy (PETD) in comparison with percutaneous endoscopic interlaminar diskectomy (PEID) for axillar herniation at L5-S1. ⋯ For axillar herniation at L5-S1, PEID can ignore the anatomic obstruction with advantages including a shorter operation time and less intraoperative radiation exposure. PETD has a clinical effect similar to that of PEID, but the process of it is more dangerous and harder than PEID.

For effective minimally invasive lumbar decompression, we changed the routine of segmental decompression. Using a high-speed drill or an ultrasound knife, we created a working channel, starting at the base of the spinous process of the upper vertebra slightly above the disc level, to target and decompress the contralateral recess, and termed it the translaminar crossover decompression (TCD). We evaluated the feasibility and compared the outcomes of a navigation-guided endoscopic translaminar crossover approach for segmental decompression (eTCD) in elderly patients with microscopic decompression using the same approach (mTCD). ⋯ TCD inherently eliminated central stenosis and facilitated decompression of both recesses via mutual undercutting, with preservation of facet joint integrity.

Spinal cord stimulation (SCS) is both relatively safe and reversible. Although SCS is generally regarded as a last resort, some of these patients will undergo additional spinal surgery after the device has been implanted or after its removal. We present a descriptive study of subsequent spinal surgery after SCS implantation. ⋯ To the best of our knowledge, the present study is the first to describe spine surgery in the setting of SCS implantation. Our results have indicated that spine surgery subsequent to, or concurrent with, SCS implantation appears to occur in few patients. Our study results suggest a modest improvement in quality of life outcomes. Therefore, clinicians should remember that patients might require further spine surgery despite the use of SCS implantation and, thus, might require reevaluation by the spine team.
