Cranioplasty after decompressive hemicraniectomy: underestimated surgery-associated complications?
Decompressive hemicraniectomy (DC) and duroplasty after malignant brain infarction or traumatic brain injury is a common surgical procedure. Usually, preserved bone flaps are being reimplanted after resolution of brain swelling. Alloplast cranioplasties are seldom directly implanted due to the risk of wound healing disorders. While numerous studies deal with DC, little is known about the encountered problems of bone flap reimplantation. Thus, aim of the study was to identify surgery-associated complications after bone flap reimplantation. ⋯ Almost one-third of the patients that are operated on for bone flap reimplantation after DC suffer from surgery-associated complications. Most often, wound healing disorders as well as bone flap resorption lead to a second or even third operation with the need for artificial bone implantation. These results might raise the question, if subsequent operations can be avoided, if an artificial bone is initially chosen for cranioplasty.

Observational StudyA population based study of outcomes after evacuation of primary supratentorial intracerebral hemorrhage.
The role of surgery after primary intracerebral hemorrhage (ICH) is controversial. To explore whether hematoma evacuation after ICH had improved short-term survival or functional outcome we conducted a retrospective observational population-based study. ⋯ Improved 3-month survival was observed in patients who had undergone hematoma evacuation relative to patients not undergoing evacuation particularly in the subgroup of patients aged≤70 years with ≥30 ml supratentorial hematomas. Surgery might improve outcome if cases could be selected more precisely and if performed before deterioration.

Immediate coma and poor outcome in subarachnoid haemorrhage are independently associated with an aneurysmal origin.
Subarachnoid haemorrhage (SAH) may present with coma and this is known to be associated with aneurysmal origin and blood load. Aneurysmal origin is associated with increased blood load and existing data do not allow us to determine if the association between coma and aneurysmal SAH is wholly due to blood load or if aneurysmal origin has an additional independent effect. The objective of our study is to find if an aneurysmal origin is a predictor of acute onset of coma independent of blood load. ⋯ Immediate coma and poor outcome in SAH are associated with an aneurysmal origin and do not characterize naSAH.

Microsurgical clipping of previously coiled intracranial aneurysms.
Endovascular coiling techniques for the treatment of intracranial aneurysms have rapidly developed as an alternative option to surgical clipping. A distinct problem after endovascular coiling is the management of a residual aneurysm neck due to incomplete filling, compaction of coils or regrowth of the aneurysm. Treatment options in this situation include surgical clipping, re-coiling, stent implantation or observation. ⋯ Coiled aneuryms with incomplete occlusion, coil compaction or regrowth of the aneurysmal neck can be successfully treated with microsurgical clipping. Coil extrusion was more often observed intraoperatively than expected. Complete occlusion of the aneurysm can be performed safely, even if loops of coils protrude into the aneurysmal neck. In these cases intraoperative removal of the coils enables secure closure of the aneurysm with a surgical clip.

Multicenter StudyProtecting facet joints post-lumbar discectomy: Barricaid annular closure device reduces risk of facet degeneration.
Lumbar discectomy is an effective treatment for lumbar disc herniation (LDH). Although the majority of patients experience successful outcomes, a significant fraction will experience a recurrence of their back pain due to facet joint degeneration. Facet joint degeneration after discectomy may be the result of excessive nuclear removal, disc space narrowing, and annular injury. ⋯ CT interpretations were collected preoperatively and 12 months post-discectomy. Patients implanted with Barricaid had significantly reduced rates and grades of facet degeneration than patients without Barricaid. Reinforcing the annulus fibrosus with Barricaid during lumbar discectomy may slow the progression of facet joint degeneration.
