The Sextant percutaneous pedicle screw fixation system is a commonly used technique. In this system, the pedicle screw and the sharp rod are placed through stab incisions. The unique mechanism of action of this system may cause unprecedented adverse effects, such as iatrogenic sacroiliac (SI) joint syndrome. ⋯ Surgeons need to be aware of iatrogenic SI joint syndrome using the Sextant system when performing percutaneous pedicle screw fixation. An endoscopy-based technique may be an effective alternative to conventional corrective surgery when treating iatrogenic SI joint syndrome using the Sextant system.

Sinus pericranii (SP) is a rare abnormal connection between the intracranial and extracranial venous drainage pathways through the osseous channels. Herein we present the case of a patient with growing SP, which was successfully treated using endovascular transvenous embolization through external compression with a plastic cup for preventing glue migration into subcutaneous veins. ⋯ Manual compression using a plastic cup was useful not only for embolization but also for reducing the physician's exposure to radiation as compared with that in the finger compression method. When a direct puncture is required, a plastic cylinder can also be used.

In this study, we present our experiences on the feasibility of rescue permanent Solitaire stent placement for failed mechanical thrombectomy (MT) and our protocol to avoid ineffective stent placement. ⋯ Permanent Solitaire stent placement might be a feasible therapy for patients with MT-failed emergency large artery occlusion. For a successful revascularization, careful antegrade flow assessment before stent detachment is critical.

Primary intraventricular hemorrhage (PIVH) is rare in the aging population and remains a challenge for cerebrovascular surgeons. In the present study, the authors reviewed the patient characteristics, angiographic results, and treatments and determined clinical outcomes in 34 patients older than 60 years of age who were treated at West China Hospital between 2010 and 2014. ⋯ Most PIVH patients were diagnosed with idiopathic PIVH in the elderly. Surgical treatment of aging patients should be optimized to improve clinical outcomes. The admission Graeb scores were considered to be the independent prognostic factors for both short-term and long-term outcomes.

Recent population-level increases in intravenous drug abuse (IVDA) may contribute to incidence of spinal infection. The aim of this study was to evaluate national trends of spinal infections and evaluate effect of IVDA on outcomes in operative management of spinal infection. ⋯ From 2002 to 2014 in the United States, the incidence of operatively treated spine infections increased 227.9%, and the proportion of cases associated with IVDA significantly increased. Patients with IVDA had a longer mean length of stay and increased inpatient cost of care but were not at increased risk for complication, reoperation, or mortality. These findings are important for surgeons, internists, hospitals, and insurers to ensure proper resource allocation in treating these at-risk patients.
