[Diagnosis and treatment of otogenic sigmoid sinus thrombophlebitis].

Objective:To summarize and analyze the clinical data of sigmoid sinus thrombophlebitis and discuss its treatment strategy. Methods:The clinical manifestations, auxiliary examinations, surgical procedures and anticoagulant therapy of patients diagnosed with otosource sigmoid sinus thrombophlebitis in the Department of Otorhinolaryngology, People's Hospital of Xinjiang Uygur Autonomous Region from November 2014 to November 2021 were retrospectively analyzed. Results:Five patients had a history of otorrhea and hearing loss for more than 5 years. They had headache during the acute episode, and 4 patients had drosive fever. They had severe complications, including brain abscess, sepsis, septic shock, intracranial hemorrhage, and hemorrhagic disseminated pneumonia. HRCT of temporal bone showed defects in the sigmoid sinus wall in 4 cases, and gas accumulation around and inside the sigmoid sinus in 3 cases. T1WI showed low signal, isosignal, and high signal in the sigmoid sinus area on MRI, and T2WI showed high signal in the sigmoid sinus area. The transverse sinus, sigmoid sinus and internal jugular vein were not developed in 2 cases, and the transverse sinus and sigmoid sinus were not developed in 1 case, and the internal jugular vein was thin. All 5 cases underwent radical mastoidectomy and resection of sigmoid sinus wall granulation or peritosinusitis abscess. The patients were followed up for 4-12 months and recovered well. Conclusion:For the cases of sigmoid sinus bone wall destruction accompanied by headache and fever by HRCT, it is necessary to be alert to the occurrence of sigmoid sinus thrombophlegitis, early diagnosis and early surgery to prevent the progression of the disease. Radical mastoidectomy combined with anti-infection therapy is the main treatment, and anticoagulation is necessary to achieve a better prognosis.目的：探讨耳源性乙状窦血栓性静脉炎的诊疗策略。 方法：回顾性分析2014年11月—2021年11月在新疆维吾尔自治区人民医院耳鼻喉科住院并确诊为耳源性乙状窦血栓性静脉炎患者的临床表现、辅助检查、手术方案及抗凝治疗情况。 结果：5例患者耳漏及听力减退病史5年以上，急性发作期均有头痛和发热，4例为驰张热，出现颅内外严重并发症，包括脑脓肿、脓毒血症、颅内出血、血性播散性肺炎等。颞骨高分辨率CT可见4例乙状窦骨壁有缺损，3例有乙状窦周、内侧积气，MRI乙状窦区T1WI可呈低信号、等信号、高信号，T2WI呈高信号，增强扫描呈窦壁强化。3例行头颅磁共振静脉造影，2例横窦、乙状窦、颈内静脉未显影，1例横窦、乙状窦未显影，颈内静脉纤细。5例均行乳突根治术+乙状窦壁肉芽或窦周脓肿切除，随访4～12个月恢复良好。 结论：无论乙状窦骨壁是否破坏，伴有头痛、发热的患者，需警惕乙状窦血栓性静脉炎的发生，早诊断早手术，防止病情进展。治疗以乳突根治术联合抗感染治疗为主，必要时结合抗凝以达到较好的预后。.
