The Potentially Fatal Ogilvie's Syndrome in Lateral Transpsoas Access Surgery: A Multi-Institutional Experience with 2930 patients.
Ogilvie's syndrome (OS) is a relatively uncommon pathology characterized by significant colonic dilation in the absence of mechanical obstruction. If unrecognized and untreated, cecal perforation resulting in a mortality rate of 25%-71% may occur. It is a potentially underdiagnosed condition in the lateral transpsoas approach population because of its uncommon nature and imitation of other well-known pathologies. ⋯ Ogilvie's syndrome is a rare but potentially fatal complication that can mimic a postoperative ileus. It is likely underdiagnosed in the lateral transpsoas approach population because of its uncommon nature and a high index of suspicion should remain. Neostigmine can be administered safely under close observation with immediate and successful outcomes. Patients with perforation require urgent laparotomy and primary repair.

Most patients with recurrence of microendoscopic discectomy (MED) need to receive revision surgery. Minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) and percutaneous endoscopic lumbar discectomy (PELD) are common operative methods for MED recurrence, but no study has been made to compare the clinical outcomes of these 2 surgical methods as revision surgery for MED recurrence. ⋯ Neither of these 2 surgical methods gave a clear advantage in long-term pain or function scores. Compared with MIS-TLIF, PELD could lead to a better perioperative result and less cost; however, the higher recurrence rate could not be ignored. Taking these characteristics into consideration was instrumental in pursuing personalized treatment for MED recurrence.

The goal of dural arteriovenous fistula of the cavernous sinus treated with coils through ultrasound-guided access to the facial vein is to interrupt the fistulous communications and decrease the pressure in the cavernous sinus and consequently in the ophthalmic veins. The traditional approach in the treatment of these fistulae is transvenous endovascular occlusion of the cavernous sinus. Transvenous embolization has been proven to be safe and can provide complete and permanent occlusion of the fistula in a single session. The most commonly used venous pathway is the inferior petrosal sinus, but, if it is inaccessible, then, the superior ophthalmic vein is considered; nonetheless, it can require a surgical exposure. Other pathways include the transfemoral transfacial vein. An arterial approach is considered usually when venous approach pathways fail. Arterial occlusion of feeders supplying the fistula is associated with a greater risk of embolic complications. ⋯ We propose an alternative pathway when the conventional transvenous approach through the inferior petrosal sinus is excluded. An ultrasound-guided facial vein approach can be considered as a direct and safe alternative to reach the cavernous sinus and obtain exclusion of the fistula.

Endovascular thrombectomy is an effective procedure to treat selected ischemic strokes, as shown in recent randomized controlled trials (RCTs). The generalizability of these trial data to real-world settings, however, is unknown. The aim of this study was to examine our single-center experience with endovascular thrombectomy for acute ischemic strokes and perform a comparative outcome analysis to the most recent RCTs. ⋯ Excellent outcomes, as demonstrated by the recent RCTs, can be achieved in clinical practice and reproduced in dedicated tertiary centers.

Observational Study
"Postoperative Delayed Paradoxical Depression (PDPD) after Uncomplicated Intracranial Aneurysm Surgery".
Postoperative delayed paradoxical depression (PDPD) is a psychiatric condition described in patients without a history of mood disorders who undergo major surgery without complications and become clinically depressed. PDPD has been recognized in major surgical interventions, including coronary artery bypass surgery. We sought to determine the incidence and potential factors associated with PDPD after surgical treatment of unruptured intracranial aneurysms. ⋯ PDPD after uncomplicated unruptured aneurysm surgery can be surprising to the neurosurgeon and the patient and should be promptly identified and addressed to achieve a full recovery. PDPD can be interpreted as a mild variant of post-traumatic stress disorder.
