OBJECTIVE
The purpose of this study was to evaluate the characteristics and meaning of the vessel wall irregularities sign, observed on computed tomography angiography of the pulmonary arteries of patients with coronavirus disease 2019 (COVID-19) pneumonia.
MATERIALS AND METHODS
This retrospective study of the computed tomography pulmonary angiography findings of 65 patients diagnosed with COVID-19 included 27 women and 38 men, with a median age of 52 years (range, 20-86 years). The diagnosis of COVID-19 was established through reverse transcription-polymerase chain reaction for infection with severe acute respiratory syndrome coronavirus 2.
RESULTS
The vessel wall irregularities sign was observed in 50 (76.9%) of the 65 patients with COVID-19. Among those 50 patients, the vascular involvement was predominantly mixed (arterial and venous) in 43 (86%), subsegmental in all 50 (100%), segmental in 13 (26%), bilateral in 46 (92%), affecting 4-5 lobes in 35 (70%), mainly in the right lower lobe in 46 (92%), and mainly in the left lower lobe in 44 (88%).
CONCLUSION
The vessel wall irregularities is a prevalent sign of vascular involvement in patients with COVID-19.
目的
本研究旨在评估2019冠状病毒病（COVID-19）肺炎患者肺动脉计算机断层血管造影中观察到的血管壁不规则征象的特征及意义。
材料与方法
这项对65例确诊为COVID-19患者的计算机断层肺动脉造影结果的回顾性研究，包括27名女性和38名男性，中位年龄52岁（范围20 - 86岁）。通过逆转录-聚合酶链反应确诊为严重急性呼吸综合征冠状病毒2感染来确定COVID-19的诊断。
结果
65例COVID-19患者中有50例（76.9%）观察到血管壁不规则征象。在这50例患者中，血管受累主要为混合型（动脉和静脉）的有43例（86%），均为亚段受累（100%），段受累的有13例（26%），双侧受累的有46例（92%），累及4 - 5个肺叶的有35例（70%），主要累及右下叶的有46例（92%），主要累及左下叶的有44例（88%）。
结论
血管壁不规则是COVID-19患者血管受累的常见征象。
