Surgical treatment of gliomas involving the supplementary motor area in the superior frontal gyrus / 中华外科杂志

<p><b>OBJECTIVE</b>To explore surgical treatment of gliomas involving the supplementary motor area (SMA) in the superior frontal gyrus.</p><p><b>METHODS</b>Clinical data and follow-up outcome of 16 patients with low graded astrocytomas involving the supplementary motor area were analyzed.</p><p><b>RESULTS</b>SMA syndrome was developed in 6 patients in whom the posterior tumor resection line was at a distance of more than 1 cm from the precentral sulcus and resolved after 12 months. Hemiplegia occurred however in 8 patients in whom the resection line was less than 1 cm to precentral sulcus and only resolved in 3 patients during follow period 12 months.</p><p><b>CONCLUSIONS</b>When the resection is performed at a distance of less than 1 cm from the precentral sulcus, surgery for gliomas of involving the supplementary motor area in the superior frontal gyrus may be result in permanent morbidity.</p>

Microsurgical treatment of proximal anterior cerebral artery aneurysms / 中华外科杂志

<p><b>OBJECTIVE</b>To explore clinic characteristics of proximal anterior cerebral artery aneurysms and analyzed operative techniques.</p><p><b>METHODS</b>A review was performed of a total of 362 patients whose aneurysms were surgically treated from June 1995 to December 2003, the morbidity of A(1) aneurysms was 2.2%. To reviewed clinical data of 8 proximal anterior cerebral artery aneurysms patients.</p><p><b>RESULTS</b>All of the aneurysms developed at the takeoff point of perforating arteries, the recurrent artery of Heubner in three cases, the medial proximal lenticulostriate artery in five cases. Six cases aneurysms projected posteriorly, two cases projected inferiorly in the surgical field. The shape of the aneurysms was saccular in all cases and diameter no larger than 5 mm in six cases. Patients were clipped satisfactorily, excellent condition in 7 patient, good condition in one.</p><p><b>CONCLUSION</b>It is important to preserve the perforating arteries and use suitable clip by avoiding cerebral ischemia.</p>
