Objective To compare the therapeutic effect of one-stage direct revascularization and medicine therapy for the treatment of ischemic moyamoya disease. Methods From March 2002 to March 2008, 18 patients with ischemic moyamoyadisease (12 males and 6 females) were treated, aged 9 to 33 years old. Eighteen patients presented with ischemic stroke, including 11 cases of cerebral infarction and 7 cases of transient ischemic attack. According to Chinese ischemic cardiovascular diseases evaluation tools, 17 patients were classified as low risk ischemic stroke and 1 as modernte risk ischemic stroke. Different levels of occlusion branch of the intracranial carotid arteries and pathosis collaterals were identified by DSA. Fourteen patients and 4 patients were showed unilateral and bilateral hypoperfusion of cerebral blood flow by single photon emission computed tomography, respectively. Eleven patients received superficial temporal artery-middle cerebral artery anastomosis and 7 patients received medicine (anti-PLT agglutinin and calcium channel blocker). Results All incisions healed at stage I. There was no stroke events during perioperation. Anastomosis vessel vasospasm occurred in 2 patients 5 days after operation; and hyperperfusion syndrome in 1 patient 2 weeks afteroperation. All patients were followed up 13-32 months (mean 18 months). In 11 anastomosis patients, 6 underwent 6 stroke events within 12 months; in 7 medicine patients, 6 underwent 11 stroke events within 12 months; and showing a significant difference (P lt; 0.05). The stroke recurrence rate was 85.7% in medicine patients and 54.5% in anastomosis patients 12 months after therapy. DSA showed pathosis collaterals in 7 anastomosis patients and 6 medicine patients 6 months after therapy. After 12 months according to modified Rankin scale, the scores of anastomosis patients were 3 points in 1 case, 2 points in 6 cases and 0-1 point in 4 cases, and the scores of medicine patients were 2 points in 2 cases and 0-1 point in 5 cases; showing no significant difference (P gt; 0.05). Conclusion As long as onset of stroke occurred and ischemic moyamoya disease is diagnosed, one-stage direct revascularization should be performed, which can reduce the rate of stroke recurrence risk and slow down the progression of disease.
Superficial temporal artery (STA) - middle cerebral artery (MCA) bypass surgery has been widely used to treat patients with moyamoya disease, and its application value in symptomatic internal carotid artery (ICA)/MCA stenosis/occlusion remains controversial. With the development of imaging, micro-devices and surgical techniques, and the deepen understanding of diseases, the effectiveness of STA-MCA bypass surgery in the treatment of symptomatic ICA/MCA stenosis/occlusion is further required. This article reviews the process of development and evolution of this surgical technique, as well as the significance and deficiencies of several randomized controlled trials of ICA/MCA treatment in the past, and looks forward to possible improvements in future research, so as to clarify the way for further randomized controlled study.
ObjectiveTo investigate the feasibility and effectiveness of repairing temporal skin and soft tissue defects and reconstructing sideburns with superficial temporal artery composite perforator flap.MethodsBetween January 2018 and January 2019, 12 patients with temporal tumors were treated. There were 5 males and 7 females with an average age of 51 years (range, 37-68 years). There were 8 cases of basal cell carcinoma and 4 cases of squamous cell carcinoma. The disease duration ranged from 3 months to 4 years (mean, 13 months). The area of residual wound after tumor resection was 3.8 cm×2.5 cm-5.2 cm×3.5 cm. The superficial temporal artery composite perforator flap was designed. The hairy superficial temporal artery frontal branch perforator flap was used to repair the hair growing area and reconstruct the sideburn; and the area of the flap was 2.5 cm×1.0 cm-4.2 cm×3.0 cm. And the superficial temporal artery descending branch perforator flap without hair was used to repair the hair-free area; and the area of the flap was 2.5 cm×1.5 cm-7.5 cm×4.0 cm. The donor sites were sutured directly.ResultsAll flaps survived, and the incisions at the donor and recipient sites healed by first intention. Eleven patients were followed up 6-12 months (mean, 9 months). The incisions were not obvious. The flaps were flat and the color of the flaps were not significantly different from the surrounding skin. The reconstructed sideburns were consistent with the healthy side and the facial appearance was satisfactory. No local tumor recurred during follow-up.ConclusionFor the temporal skin and soft tissue defects involving the sideburn, the superficial temporal artery composite perforator flap can be used to repair subunits with different aesthetic characteristics in sections and has the advantages of operating simply, obtaining satisfied facial appearance, and little effect on the donor site.
