OBJECT: Microsurgical anastomosis from the superficial temporal artery (STA) to the middle cerebral artery (MCA) is a treatment option for appropriately selected patients with cranial atherosclerotic steno-occlusive disease (CASD). However, the long-term efficacy and patency of the donor artery remain unclear. We reviewed the signal intensity of the donor artery on magnetic resonance angiography (MRA) after STA-MCA anastomosis in patients with CASD and clarified the incidence of and risk factors for reduction in postoperative signal of STA...

BACKGROUND & AIMS: Non-relaxing pelvic floor dysfunction (N-RPFD), or dyssynergic defecation, is the paradoxical contraction and/or impaired relaxation of pelvic floor and anal muscles during defecation. Few studies have evaluated this disorder in patients with an ileal pouch-anal anastomosis (IPAA). We investigated the frequency of N-RPFD in patients with and without chronic pouchitis following IPAA and the effectiveness of biofeedback therapy within this population. METHODS: We conducted a retrospective study of all patients with an IPAA who underwent anorectal manometry (ARM) between January 2000 and March 2015 (n=111)...

Perioperative compression neuropathy is a known potential complication of prolonged surgical procedures. Sciatic postoperative neuropathy has rarely been reported. We present a 34-year-old woman who underwent right breast reconstruction with supercharged (venous anastomosis) transverse rectus abdominis flap and developed bilateral sciatic compression neuropathy. Her history was remarkable for sleeve gastrectomy 2 years earlier resulting in 105 pound weight loss 1 year before breast reconstruction. During the procedure, the patient was in the supine position for 8 hours and in the semirecumbent position for an additional 2 hours with the torso flexed at 30 degrees and knees flexed at approximately 45 degrees in addition to standard padding...

Here we describe the case of a patient with moyamoya disease who developed cerebral infarction followed shortly by subarachnoid hemorrhage and intracerebral hemorrhage. A 50-year-old woman presenting with sudden and transient weakness of the left lower limb was transferred to a local hospital. Magnetic resonance imaging(MRI)revealed cerebral infarction in the corpus callosum and in the bilateral frontal lobes induced by moyamoya disease. Pyramidal tract was not affected. The patient was treated with an anti-platelet agent(ozagrel sodium 160mg/day)and did not undergo intentional antihypertensive therapy...

A persistent trigeminal artery (PTA) is the most common carotid-vertebrobasilar anastomosis. PTA variants terminating on cerebellar arteries instead of the basilar artery have been reported previously. We present the first case of a PTA communicating with a fetal posterior communicating artery identified on a magnetic resonance angiogram. An understanding of these anatomical variants is important to clarify pathological processes that can help guide neurosurgical and endovascular procedures.

Portal biliopathy (PB) is defined as the presence of biliary abnormalities in patients with non-cirrhotic/non-neoplastic extrahepatic portal vein obstruction (EHPVO) and portal cavernoma (PC). The pathogenesis of PB is due to ab extrinseco compression of bile ducts by PC and/or to ischemic damage secondary to an altered biliary vascularization in EHPVO and PC. Although asymptomatic biliary abnormalities can be frequently seen by magnetic resonance cholangiopancreatography in patients with PC (77%-100%), only a part of these (5%-38%) are symptomatic...

A 25-year-old man presented with a mass on the right medial canthus after a successful dacryo cys torhinostomy performed 3 years ago. On examination, there was a firm, nondepressible mass inferior to the medial canthal ligament and a linear vertical scar on the lateral wall of the nose. Syringing through the right lower punctum indicated his lacrimal system was patent. Computed tomography and magnetic resonance imaging disclosed a large cystic lesion in the lacrimal sac fossa. No bone erosion was detected. The mass was approached through a tear trough incision and completely resected...

BACKGROUND: Spinal epidural abscess is a rare condition with high morbidity and mortality, for which a delay in diagnosis and treatment can lead to irreversible neurologic deficit or even death. Although patients with spinal epidural abscess have systemic predisposing immunocompromised conditions, spinal intervention, or trauma, this condition has been reported as a result of perforation or fistulization arising from inflammatory bowel disease. We describe herein a rare case of spinal epidural abscess as a complication of ileal pouch anal anastomosis...

Choledochal cyst is a rare pathological condition, which represents 1% of benign diseases of the biliary tract. It is seen with significant frequency in childhood, with a higher prevalence in females, and a greater diagnostic incidence in Asia. Diagnosis is primarily based on clinical suspicion. Its symptoms are variable, and its treatment, depending on the type, is surgical. CASE REPORT: a male patient, 46 years old, with clinical symptoms of acute pancreatitis as a complication of a choledochal cyst Todani type II is diagnosed during his hospital stay with cholangial magnetic resonance...

INTRODUCTION: The Rubinstein-Taybi syndrome and pancreas divisum are uncommon diseases in children. The Rubinstein-Taybi syndrome diagnosis is only clinical, and mental retardation and dysmorphic features mainly characterize it. The PD relates to idiopathic pancreatitis in 7.5% of patients suffering from this disorder. It has not been found any cases reported where these diseases are associated and the management of patients with pancreatitis associated with PD is still a challenge. CLINICAL CASE: A patient diagnosed with Rubinstein-Taybi syndrome has recurrent abdominal pain of six months and elevated pancreatic enzymes, he underwent a magnetic resonance imaging where pancreas divisum is suspected...

The accessory middle cerebral artery (MCA) is a common variation of the MCA that arises from the anterior cerebral artery. We report a patient with anastomosis of the accessory MCA with the main MCA, an extremely rare variant that we diagnosed by magnetic resonance (MR) angiography. Both partial maximum-intensity-projection and partial volume-rendering MR angiographic images obtained at 3 T are useful to identify such rare vascular variation.

PURPOSE: Surgical procedures for high imperforate anus have ranged from the posterior sagittal anorectoplasty (PSARP) to laparoscopic-assisted anorectoplasty (LAARP). PSARP bisects the sphincter muscle complex, introducing muscle injury and scarring. LAARP uses a straight trocar to traverse an often non-linear sphincter muscle complex. MRI-assisted LAARP (MRI-LAARP) guides the neorectum precisely through the middle of the entire sphincter complex along its trajectory. We present our experience utilizing MRI intraoperatively during LAARP...
