Clinical manifestations and neuroimaging characteristics of children with moyamoya disease / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To study the clinical manifestations and neuroimaging characteristics of pediatric moyamoya disease.</p><p><b>METHODS</b>The clinical data of 17 children with moyamoya disease were retrospectively studied.</p><p><b>RESULTS</b>The onset age was between 3 and 14 years. The main clinical manifestations included motor weakness of extremities or hemiplegia, sensory disturbance and headache. Cranial CT or/and MRI examinations predominately showed cerebral infarct. Magnetic resonance angiography (MRA) and digital subtraction angiography (DSA) showed stenosis or occlusion at the terminus of the siphon portions of internal carotid arteries and proximal portions of anterior or middle cerebral arteries, and abnormal vascular networks at the base of brain.</p><p><b>CONCLUSIONS</b>Cerebral ischemia is main clinical manifestations in children with moyamoya disease, presenting motor weakness of extremities or hemiplegia, sensory disturbance and headache. DSA is essential to the diagnosis of the disease.</p>

The first metatarsal web space: its applied anatomy and usage in tracing the first dorsal metatarsal artery in thumb reconstruction / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To clarify the anatomical relationship of the structures in the first toe webbing space for better dissection of toes in thumb reconstruction.</p><p><b>METHODS</b>The first dorsal metatarsal artery, the first deep transverse metatarsal ligament and the extensor expansion were observed on 42 adult cadaveric lower extremities. Clinically the method of tracing the first dorsal metatarsal artery around the space of the extensor expansion was used in 36 cases of thumb reconstruction.</p><p><b>RESULTS</b>The distal segments of the first dorsal metatarsal artery of Gilbert types I and II were located superficially to the extensor expansion. The harvesting time of a toe was shortened from 90 minutes to 50 minutes with 100% survival of reconstructed fingers.</p><p><b>CONCLUSIONS</b>The distal segment of the first dorsal metatarsal artery lies constantly at the superficial layer of the extensor expansion. Most of the first metatarsal arteries of Gilbert types I and II can be easily located via the combined sequential and reverse dissection around the space of the extensor expansion.</p>
