Objective To approach the enhancing patterns of hepatic focal nodular hyperplasia (FNH) under contrast-enhanced ultrasound, and improve the recognition on diagnosis for FNH by contrast-enhanced ultrasound. Methods The clinical data of 12 patients with histologically proved FNHs having accepted contrast-enhanced ultrasound examination from May 2007 to February 2009 in West China Hospital of Sichuan University were retroptectively analyzed, and related literatures were reviewed. Results All FNHs were rapidly enhanced in arterial phase and spoke-wheel-like sign was detected in 9/12 lesions. Slightly hyper-enhancement or iso-enhancement were showed in 11/12 lesions, while 1/12 lesions showed hypo-enhancement in late phase. Conclusion Contrast-enhanced ultrasound can display the dynamic blood perfusion of FNH, especially spoke-wheel-like arterial flow in early arterial phase, which is of great value for the diagnosis of FNH.
目的 通过总结韧带样型纤维瘤病（DF）的超声图像表现和病理学结构，以提高对DF的认识和诊断水平。 方法 回顾性分析2005年1月－2011年12月70例经手术和病理组织学证实为DF患者的超声图像和病理组织学结果。 结果 DF肿块的超声表现与病理结构密切相关。70例DF中腹部外型41例（58.6%）、腹壁型18例（25.7%）、腹内型11例（15.7%）。DF的典型超声图像表现为沿肌纤维浸润性生长的低回声肿块,累及多块肌肉；肿块无包膜,多数形态不规则、边界不清；其中8例包绕和侵犯相邻骨质, 12例肿瘤压迫或侵犯邻近血管、神经、肠管等组织；40例瘤体内探及Ⅰ级血流信号，4例探及Ⅲ级血流信号；所有病变均未见坏死出血和囊变，病变周围无淋巴结肿大。 结论 DF的声像图表现有较强的特征性，超声能较为准确判断肿块累及范围、是否侵犯相邻骨质、与毗邻血管、神经的关系，有助于制定手术计划。
Objective To explore the clinicopathologic features and treatment of desmoplastic small round cell tumor (DSRCT). Methods By summarizing the diagnosis and treatment of a DSRCT patient with liver metastasis, who was admitted to Department of Liver Surgery in West China Hospital in October 2017, and exploring its clinicopathologic features and treatment by reviewing literatures. Results This patient was generally in good condition, after the multi-disciplinary discussion between the imaging physician, the oncologist, and the liver surgeon, it was considered that there were indications of operation, and after communicating with the patient’ families, actively chose surgical treatment. The performance was successful, and this patient was treated with adjuvant chemotherapy postoperatively. The operative time for this patient was 5 hours, and blood loss was 600 mL. There was no complication occurred, such as bleeding, bile leakage, and intestinal fistula, and discharged on 8 days after surgery. This patient was followed up for 10 months, without tumor recurrence and metastasis occurred. The results of literatures showed that, DSRCT was more common in young male population, the mean age was 12–27 years old, the longest median survival time was 39.2 months, and 3-year survival rate was 20.8%–71%. Those patients who received surgery, had longer median survival time. Conclusions DSRCT is a rare aggressive soft tissue sarcoma, which is usually diagnosed with multiple organ metastases. The treatment is mainly multi-mode treatment based on surgical resection combined with radiotherapy and chemotherapy, but the overall prognosis is poor.
ObjectiveTo investigate the correlation between lung ultrasonography and pulmonary complications after cardiac surgery.MethodsFifty-two patients after cardiac surgery in our hospital from January to May 2017 were recruited. There were 27 males and 25 females, aged 60.50±10.43 years. Lung ultrasonography was performed by specially trained observers, video data were saved, and lung ultrasound score (LUS) were recorded. The correlation between the LUS and the patients' pulmonary function was evaluated.ResultsLUS was 17.80±3.87, which was negatively correlated to the ratio of arterial PO2 to the inspired oxygen fraction (PaO2/FiO2) during examination, without significant difference (r=–0.363, P=0.095), but significantly negatively correlated to PaO2/FiO2 changes 24 hours postoperatively (r=–0.464, P=0.034).ConclusionThe changes of lung ventilation area may occur earlier than the changes of lung function. Bedside LUS is an effective method for clinical monitoring of pulmonary complications.
