Endoneurial Blood Flow

The blood supply (vasa nervorum) to peripheral nerves is composed of an interconnected dual circulation. The endoneurium of nerve fascicles is maintained by the intrinsic circulation which is composed of microvessels primarily of capillary caliber. Transperineurial arterioles link the intrinsic circulation with the extrinsic arterial supply located in the epineurium. Blood flow in the vasa nervorum is neurogenically influenced (1,2). Although a recent hypothesis proposes that endoneurial blood flow is controlled by the action of autonomic nerve fibers associated with epineurial arterioles (2), our recent studies (3) show that in addition to epineurial arterioles other segments of the vasa nervorum are also innervated. In this study, we examine blood vessels of the endoneurium for possible innervation.

Sjögren‘S Syndrome

Background:Peripheral neuropathy is one of the most frequent extraglandular manifestations of primary Sjögren’s syndrome (pSS). The diagnosis of peripheral neuropathy complications of pSS is based primarily on careful neurologic examination and electrodiagnostic tests. The value of ultrasound in peripheral nerve has been recognized. However, little clinical researches have focused specifically on cutaneous nerve of pSS.Objectives:To evaluate the morphological changes of sural nerve in patients with pSS by high-frequency ultrasound.Methods:The prospective study subjects consisted of 31 consecutive pSS patients underwent sural nerve biopsy and 30 healthy volunteers as controls. The ultrasonic presentations of the fascicle, perineurium, epineurium of sural nerve were observed, and the cross-sectional areas (CSA) of the sural nerves was measured.Results:Among the 21 sural nerves confirmed by pathology, all showed the thickening of the perineurium and epineurium (Figure 1-2), and abnormal blood flow signal in perineurium or epineurium in 14 cases (Figure 2). The mean CSAs were (1.41±0.44) mm2 for the control group, and (1.58±0.48) mm2 for the case group (P>0.05). In addition, the abnormal blood flow signal in sural nerve correlated with disease activity.Conclusion:This study indicated that high-frequency ultrasound may be a valuable tool for evaluating cutaneous nerve neuropathy of Sjogren’s syndrome patients.References:[1]Vitali C, Bombardieri S, Jonsson R, Moutsopoulos HM, Alexander EL, Carsons SE, et al.

ABSTRACTSevere peripheral nerve injury occasionally requires urgent nerve grafting especially with significant separation of the proximal and distal ends of the injured nerve. Proper reinnervation to provide continued sensory and motor function is essential especially in the pediatric population. These patients would suffer lifelong disability without correction, yet have significantly improved regenerative capacity with prompt and effective management, making nerve grafts an ideal choice for complete nerve transection. This case report describes the successful sural nerve cable graft reinnervation of a transected femoral nerve in a 21-month-old male. This procedure was made difficult by severe trauma to the surrounding area with laceration of the femoral artery, significant separation of the femoral nerve ends, and the compact anatomy of such a young patient.
