Ligamentum Flavum Hematoma Accompanied by Intraspinal and Extraspinal Hematomas: A Case Report.

Studies on ligamentum flavum hematoma (LFH) have been gradually increasing; however, no study has reported an LFH spreading to the intraspinal and extraspinal spaces. The purpose of this report is to discuss this rare condition and report that extraspinal hematoma can be formed by LFH. The authors present the case of a 78-year-old man presented with right L5 radiculopathy caused by a space-occupying lesion with intraspinal and extraspinal expansions at the L4-L5 vertebral levels demonstrated on MRI.

Intestinal flow after anastomotic operations in neonates.

Stagnation of contents at the anastomotic site for intestinal flows after anastomotic operation is a critical issue in neonates. Although various anastomosis methods have been developed, in the clinical field, poor passage at the anastomotic site in cases of jejunal atresia is still observed. A CFD study was carried out to clarify the reasons for the stagnation and to find favorable anastomosis methods from a fluid dynamical point of view.

Radiological Examination of Postoperative Cervical Alignment and Stability in Patients with Dialysis-Associated Spondylosis Excluding Destructive Spondyloarthropathy: Comparison with Patients with Cervical Spondylotic Myelopathy.

Introduction: Several reports have demonstrated the surgical treatment strategy for patients with dialysis-associated spondylosis in the cervical spine (CDAS) with destructive spondyloarthropathy (DSA). However, studies focusing on the clinical outcome of patients with CDAS without DSA remain scarce. We aimed to review the treatment strategy of patients with CDAS but without DSA.

Modification of hemodynamics in basilar artery aneurysm by the single and Y stent placement1.

Background: Stent placement can change the hemodynamics in basilar artery aneurysms. However, the effects of the stent placement can depend on the angle of vessel bifurcation.

Objective: The hemodynamics in and near the aneurysm are investigated for two angles of vessel bifurcation and two stent models.

Risk factors for re-recurrent carpal tunnel syndrome in patients undergoing long-term hemodialysis.

The purpose of this study was to evaluate risk factors for re-recurrent carpal tunnel syndrome (CTS) in long-term renal hemodialysis (HD) patients. Fifteen wrists of ten HD patients, follow-up period of minimum seven years after reoperation of CTS, were included in this study. Duration of HD, period from first operation to reoperation, shunt side was involved or not, presence of trigger finger and cervical destructive spondyloarthritis, and operative procedure performed during the reoperation (synovectomy was performed or not) were evaluated.

Sclerosing perineurioma: a clinicopathological study of five cases and diagnostic utility of immunohistochemical staining for GLUT1.

We reviewed five cases of sclerosing perineurial tumor of the hand. Four patients were male and one was female with ages ranging from 11 years to 49 years (mean 26 years). The predominant reason for consultation at the outpatient clinic was a slowly growing painless mass.
