Dehiscence after a wound has healed is a known complication of craniotomy for tumor resection. We conducted a retrospective analysis of 64 patients who underwent craniotomy for tumor resection followed by radiation or radiosurgery between 2006 and 2010. ⋯ These treatments may be risk factors for developing delayed dehiscence and, in combination, may potentiate local wound healing problems. Potential mechanisms and management strategies are discussed.

Randomized Controlled Trial
A prospective study of Gasserian ganglion pulsed radiofrequency combined with continuous radiofrequency for the treatment of trigeminal neuralgia.
We conducted a prospective randomized controlled study to evaluate whether continuous radiofrequency (CRF) combined with pulsed radiofrequency (PRF) to the Gasserian ganglion (GG) decreases the side effects of CRF while preserving efficacy. Sixty patients diagnosed with classic trigeminal neuralgia (TN) were treated with either 75°C CRF for 120 s to 180 s (SCRF group), 75°C CRF for 240 s to 300 s (LCRF group), or 42°C PRF for 10 minutes (min) followed by 75°C CRF for 120 s to 180 s (PCRF group). Patients were assessed for pain intensity, quality of life (QOL), and intensity of facial dysesthesia before (baseline), and at seven days, three months, six months, and 12 months after the procedure. ⋯ After 12 months, >70% of patients in each group had complete pain relief, and the QOL in all three groups had increased significantly compared to baseline. The intensity of facial dysesthesia was mildest in the SCRF group and most severe in the PCRF group on the seventh day after the procedure, but most persistent in the LCRF group. Patients who receive PRF combined with CRF to the GG can achieve comparable pain relief to those who receive CRF alone, and shorter exposure of CRF could result in less destruction of the target tissue.

It has been found that the hemostatic system is activated following a brain injury. To explore the role of D-dimer in spontaneous intracerebral hemorrhage (ICH), this prospective study aimed to evaluate the association between serum D-dimer concentration, clinical outcome and radiographic findings of ICH patients in the emergency department (ED). ⋯ Diabetes mellitus (odds ratio [OR]: 2.93; 95% confidence interval [CI]: 1.1-7.76, p=0.031), ICH volume (OR: 1.16; 95% CI: 1.07-1.27, p<0.0001) and D-dimer concentration (OR: 2.72; 95% CI: 1.08-6.9, p=0.002) were associated with 30-day mortality. This study shows that in patients with spontaneous ICH, a higher initial D-dimer concentration is associated with higher 30-day mortality.

After the introduction of Guglielmi Detachable Coils (GDC), endovascular management of ruptured and unruptured aneurysms became a viable alternative to surgical clipping as a "minimally invasive" option. Endovascular management of aneurysms became even more common after the International Subarachnoid Aneurysm Trial, which was one of the first prospective, randomized trials comparing clipping and coiling, showed reduced dependency and death in patients undergoing coiling after two months and one year. ⋯ In addition, treatment failures (recurrent and residual aneurysms after coiling) pose difficult treatment scenarios fraught with complications due to surrounding adhesions, coil migration and involvement of adjacent neurovascular structures. Thus, we analyzed the recent literature dealing with the nuances of clipping after coiling and reviewed the current management principles involved in treating these difficult aneurysms.
