Minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) for lumbar spondylolisthesis allows for surgical treatment of back and leg pain while theoretically minimizing tissue injury and accelerating overall recovery. Although the authors of previous studies have demonstrated shorter length of hospital stay and reduced blood loss with MIS versus open-TLIF, short- and long-term outcomes have been similar. No studies to date have evaluated the comprehensive health care costs associated with TLIF procedures or assessed the cost-utility of MIS- versus open-TLIF. As such, we set out to assess previously unstudied end points of health care cost and cost-utility associated with MIS- versus open-TLIF. ⋯ Although our limited sample size prevented statistical significance, MIS- versus open-TLIF was associated with reduced costs over two years while providing equivalent improvement in QALYs. MIS-TLIF allows patients to leave the hospital sooner, achieve narcotic independence sooner, and return to work sooner than open-TLIF. In our experience, MIS- versus open-TLIF is a cost reducing technology in the surgical treatment of medically refractory low-back and leg pain from grade I lumbar spondylolisthesis.

Comparative Study
Cognitive changes in patients with aneurysmal subarachnoid hemorrhage before and early posttreatment: differences between surgical and endovascular.
The main purpose of occluding a ruptured aneurysm is preventing rebleeding, which may be fatal. Microsurgical or endovascular treatments are the main approaches adopted to prevent new bleeding. Among patients presenting with aneurysmal subarachnoid hemorrhage, about 50% had permanent injuries. Cognitive changes are one of the main morbidities from that illness. The type of treatment for the aneurysm (clipping or coil embolization) can also contribute to the genesis of those complications. ⋯ One hundred fifty-one patients were assessed, distributed as 122 surgical and 29 coil embolized. The performances in both groups did not differ in the initial assessment. However, endovascular treatment does not show additional cognitive impairment and had a better performance in language and verbal memory, compared with patients submitted to surgical treatment in an early postoperative period.

Case Reports
Beneficial use of a new hand-held CO2 laser fiber in resection of a calcified and vascular intraventricular tumor.
The progression of laser technology in neurosurgery has been limited by the poor maneuverability of traditional line-of-sight carbon dioxide (CO2) lasers and the propensity of other laser energies to cause collateral thermal injury to adjacent neural structures. The advent of a dielectric omnidirectional reflector and the subsequent development of phototonic bandgap fibers (PBF) have transformed the CO2 laser into a low-profile instrument with considerable dexterity and many potential new neurosurgical applications. ⋯ The CO2 laser was exceptionally useful in the resection of this long-standing and extremely calcified, yet vascular mass. A review of the evolution of laser technology applications in neurosurgery is presented, with a specific focus on the innovations that led to the development of the new PBF CO2 laser. This new technology may be advantageous in tumor surgery, particularly in the resection of long-standing calcified and vascular tumors that are not amendable to traditional surgical techniques.

To highlight pertinent aspects of emergent endovascular management of carotid rupture, or carotid blowout syndrome (CBS), an emergent, life-threatening complication of head and neck cancer and its treatments. ⋯ The treatment of patients with terminal malignant disease and CBS should provide maximum relief and minimize the risks of repeat surgery, morbidity, and mortality. Endovascular management of CBS with deconstructive techniques achieves immediate hemostasis and definitive treatment. The risks of intraoperative mortality and recurrent hemorrhage are low.

Capillary hemangiomas are benign vascular lesions involving the skin and soft tissues that commonly occur at birth or an early age. Intracranial capillary hemangiomas are extremely rare; only 14 cases have been reported the literature. ⋯ Surgery is an option for symptomatic intracranial capillary hemangiomas. However, because partial removal is associated with a high recurrence rate, capillary hemangiomas that cannot be removed radically should be treated with radiotherapy, which offers the possibility of controlling lesion size and preventing tumor recurrence.
