Total mesorectal excision (TME) is a mile-stone procedure in the history of rectal cancer surgery, but the exposure of surgical field of distal rectum is usually poor in patients with male, obese and narrow pelvis, which may lead to tumor residue and relative complications. Recently, a new technique called transanal TME (taTME) is considered to solve the above problems, but most medical centers are still in the learning curve of this procedure. Therefore, anatomical planes and landmarks of taTME for rectal cancer and prophylaxis of intraoperative complications are induced in this paper, which includes posterior plane: angle of anus and distal mesorectum and bleeding of mesorectum; rectosacral fascia and presacral bleeding; lateral and posterior-lateral plane: posterior branches of pelvic plexus and damage of anal function; anterior plane: vessel branches of neurovascular bundle and bleeding...

BACKGROUND: Intracranial mycotic aneurysm (IMA) is a rare neurovascular disease and a well-known complication following infective endocarditis. IMAs potentially carry a high mortality risk due to intracranial hemorrhage. Therefore, initial treatment is crucial for IMA patients, but an optimal treatment strategy remains unknown. Herein, we report two cases of IMA patients treated with the current usual modalities, and we provide a comprehensive literature review to propose an optimal initial treatment strategy for IMAs...

Skull base chordoma is a rare tumor arising from embryonic remnants of the notochord with invasive potential. Due to the destruction of osseous landmarks and invasion of surrounding structures, surgical resection is challenging. The authors explored the clinical value of a multimodal neuronavigation system in skull base chordoma resection using a neuroendoscope. Between January 2012 and January 2016, the authors utilized neuroendoscopy to excise skull base chordoma in 93 patients. The authors performed 45 operations assisted by multimodal neuronavigation (neuronavigation group) and 48 without intraoperative imaging guidance (control group)...

The most common procedure to address transverse glenoid fractures that are characterized by intra-articular step-off or gapping is open reduction and internal fixation. Disadvantages of open surgery are delay in regaining full range of motion, increased approach morbidity, neurovascular complications, and the need for capsulotomy, which delays healing and increases the risk of stiffness. An arthroscopically assisted fracture fixation, as described in this article, is characterized by better visualization of the glenoid articular surface and reduction of the intra-articular fragments under direct vision, which diminishes the chances of residual step-off after fixation...

Medical treatment including lifestyle and dietary modifications and drug therapy remains the mainstay of treatment for gouty arthritis of the hand and wrist. Without proper and timely treatment, tophi develop approximately 10 years after the onset of the disease. Open surgery for tophaceous gout is associated with a relatively high rate of complications particularly related to the surgical wound and overlying skin necrosis. Intralesional shaving of the tophi through small incisions has been reported and has the advantage of fewer wound complications...

PURPOSE: Shared decision-making, when physicians and patients collaborate and agree on health care decisions, is a key tenant of patient-centered care. Choice of access site for neurovascular procedures is rarely a shared decision point between physicians and patients. We present our initial evaluation of patient preference for radial over femoral access for cerebrovascular procedures. MATERIALS AND METHODS: IRB approved single-center, prospective, and consecutive survey of all patients undergoing transradial access for cerebrovascular imaging and intervention...

BACKGROUND AND PURPOSE: Flow diversion may have advantages in the treatment of posterior communicating artery (PComA) aneurysms associated with a fetal origin posterior cerebral artery (PCA), which can be challenging to treat with conventional techniques. However, a PComA incorporated into the aneurysm may prevent or delay aneurysm occlusion. Also, coverage of a fetal origin PCA risks infarction of a large vascular territory. The purpose of this study was to examine the safety and effectiveness of using the Pipeline Embolization Device (PED) to treat PComA aneurysms associated with a fetal origin PCA...

Over the past 10 to 20 years, endoscopic endonasal surgery has become for many teams the preferred treatment for sinonasal tumors. Technical advances in the field of surgical instrumentation (good visualization, hemostasis…) and the progress of imaging guidance (to avoid neurovascular complication) has made those procedures simpler and safer. Nevertheless, endonasal endoscopic procedures require a trained surgical team of ENT specialist and neurosurgeon. Endoscopic endonasal surgery has been reported to be feasible for all types of sinonasal tumors whether benign tumors such as inverted papillomas, or malignant tumors...

BACKGROUND: Cerebral malaria (CM) is a severe complication of Plasmodium falciparum infection which may result in death or developmental disability. The pathologic processes leading to CM are not fully elucidated; however, widely accepted mechanisms include parasite sequestration, release of infected red blood cell contents, activation of endothelial cells, increased inflammatory responses, and ultimately dysfunction of the neurovascular unit (NVU). The endothelium plays a central role in these processes as the site of parasitized erythrocyte sequestration and as the regulator of fluid extravasation into the central nervous system...

INTRODUCTION: Radial club hand deformity acquired post haematogenous osteomyelitis of radius bone is a very rare disease. Resulting in functional and cosmetic deficit of upper limb which is similar to congenital cases. For a long-time various surgeons attempted to reconstruct the deformity by bone grafting, plating, Ilizarov, monorail external fixator, callus distraction and so on. Keeping in mind that creating single bone forearm we proposed centralization of ulna on wrist to correct the deformity...

The experience in the management of thromboembolic complications of distal vessels during coil embolization using stent-retrievers in the setting of subarachnoid hemorrhage (SAH) is still limited. We report a case of 58-year-old woman with a ruptured small anterior communicating aneurysm who experienced during coil embolization a thromboembolic occlusion of the upper post-bifurcation branch of the middle cerebral artery. Mechanical thrombectomy with a stent-retriever (Solitaire, Covidien, Neurovascular) resulted in complete recanalization of the occluded branch with no ischemic complication...

This was a retrospective observational study. The aim of this study was to evaluate functional outcomes in children treated for Gartland III supracondylar humerus (SCH) fracture with neurovascular (NV) injuries using validated outcome measures. A secondary goal was to determine whether clinical parameters such as age at injury, sex, weight, fracture site, and/or direction of displacement could predict NV injury at the time of fracture or long-term functional outcomes in these patients.One hundred fifty-four patients of Gartland III SCH fractures between March 2004 and May 2013 were studied retrospectively...

Brain dysfunction, especially cognitive impairment, is one of the main complications in Alzheimer's disease (AD), which threatens the health of 46.8 million people worldwide. At present, the pathogenesis of cognitive dysfunction is only partially understood, and effective therapies for memory loss in AD remain elusive. Tetramethylpyrazine (TMP) is one of the major bioactive compounds purified from Chuanxiong, a Chinese herb used for the treatment of neurovascular and cardiovascular diseases. The neuroprotective properties of TMP are evident in some neurodegenerative diseases, including Parkinson's disease...

Proximal humerus fracture fixation may be complicated by persistent postsurgical stiffness or implant-related problems. Arthroscopic plate removal is a cosmetic and functionally beneficial procedure; however, the procedure is technically difficult in the presence of severe subdeltoid scarring. The technique described here shows an arthroscopic subdeltoid adhesiolysis and proximal humerus plate removal using systematic access to 5 regions of screw positions on the plate. After initial glenohumeral adhesiolysis, a thorough subacromial and subdeltoid bursectomy is performed...
