Anterior cingulotomy (AC) was originally used to treat patients with a psychiatric disorder, but it is also useful for treating patients with chronic intractable pain. We reviewed 24 patients at our hospital who underwent AC for chronic intractable pain to determine whether surgery influenced patient cognition and the pain circuit. ⋯ A stereotactic AC was safe and effective in resolving chronic refractory pain. It did not affect patient cognition or the sensory conductive pathway. However, patients who had recurrent intractable pain after a cingulotomy did not respond well to the reoperation.

To date, no controlled studies on the treatment of carotid artery dissection (CAD) have been reported. The purpose of this study was to demonstrate the technical feasibility and clinical efficacy of stent-supported angioplasty (SSA) as primary treatment for acute stroke due to CAD. ⋯ Our results provide evidence that SSA is a feasible and effective strategy as primary treatment for steno-occlusive CAD patients with significant hypoperfusion or a large penumbra.

Oblique lumbar interbody fusion is a commonly used surgical method of achieving lumbar interbody fusion. There have been some reports about complications of oblique lumbar interbody fusion at the L2-L3 level. However, to our knowledge, there have been no reports about ureter injury during oblique lumbar interbody fusion. We report a case of ureter injury during oblique lumbar interbody fusion to share our experience. ⋯ Our study shows that a low threshold of suspicion of ureter injury and careful manipulation of retroperitoneal fat can be helpful to prevent ureter injury during oblique lumbar interbody fusion at the upper level.

The routine use of intraoperative magnetic resonance imaging (iMRI) helps to achieve gross total resection in transsphenoidal pituitary surgery. We compared the added value of iMRI for extent of resection in endoscopic versus microsurgical transsphenoidal adenomectomy. ⋯ With the endoscopic approach, significantly more tumor volume reduction was achieved before conducting iMRI, decreasing the need for further resection. This finding was even more pronounced in adenomas graded Knosp 0-2. In the case of extensive and invasive adenomas with infiltration of cavernous sinus and suprasellar or parasellar extension, additional tumor resection and increase in the extent of resection was achieved with iMRI in both groups. The endoscopic approach seems to result in better endocrine outcomes, especially in Knosp grade 0-2 pituitary adenomas.

The purpose of this study was to analyze the outcomes and complications of the endoscopic endonasal approach (EEA) performed on patients with Cushing disease at our Pituitary Center during the past 11 years. ⋯ The EEA for Cushing disease resulted in remission and complication rates comparable with previous analyses of EEA, as well as microsurgical series. Preoperative adrenocorticotropic hormone levels were associated with invasiveness.
