Prevention of Thromboembolic Complications after Spine Surgery by the Use of Low-molecular-weight Heparin.
This study aimed to evaluate the effectiveness and safety of the use of low-molecular-weight heparin (LMWH) in the prevention of thromboembolic complications after spine surgery. ⋯ The use of LMWH significantly decreases the incidence of thrombosis and thromboembolic complications after spine surgery, but increase the incision bleeding, leading to an elevated risk of symptomatic spinal epidural hematoma.

The outcomes of repeat stereotactic radiosurgery (SRS) after failure of previous SRS are not well established. We report our overall experience using SRS for the retreatment of locally recurrent brain metastases. ⋯ Repeat SRS is feasible for select patients, particularly for those with tumor volume ≤4 cm3. Further evaluation is needed to establish the most appropriate treatment doses and volumes for this approach.

To report a single-institution experience with isolated transverse process fractures (ITPFs) and provide increasing support for the development of evidence-based guidelines. The authors also evaluated the presence of concerning symptoms or red flags that may indicate additional, underlying injuries in the setting of ITPFs. ⋯ Several factors were identified as significant markers of associated injuries, including female sex, MVA, and presenting symptoms. Neck and chest pain were significantly associated with vascular injuries. Clinicians should maintain high indices of suspicion for associated injuries in patients with ITPFs, especially after high-velocity mechanisms.

Intracranial hemangiopericytoma is a rare tumor with high recurrence rate. We analyzed adverse factors for recurrence and survival of patients with hemangiopericytoma. ⋯ This study revealed risk factors for PFS and overall survival to predict outcomes and determine treatments. GTR was attempted as frequently as possible, and PRT was recommended for patients with non-GTR or recurrence to improve tumor control.
