目的：目的：应用胸部CT对肺动脉高压（PAH）患者和非PAH患者的冠状窦（CS）进行识别和测量。结果：在所有60例（平均值+/- SD，60.5 +/- 17.5岁; 45%男性）无PAH（对照组）（平均值+/- SD，直径7.05 +/- 1.90 mm）的患者中，均发现了CS。24例（9例男性;平均年龄+/- SD，54.1 +/- 14.5岁）已知或疑似PAH（研究组），肺动脉（PA）压力升高; CS扩张（平均SD，9.4 ± 4.2 mm）;其大小与右房压力相关（r = 0.358，P = 0.061），平均PA压力（r = 0.568 P = 0.005），收缩压（r = 0.375，P = 0.071），舒张期PA（r = 0.561，P = 0.004）。在PAH患者中，CS扩张与PA压力升高相关。
Objective: To identify and measure the corollary sinus (CS) in patients with and without pulmonary artery hypertension (PAH) using chest computed tomography (CT).Methods: Using a 4-channel GE LightSpeed CT scanner, nongated axial chest CT images were obtained after intravenous injection of contrast material. Catheterization of the right side of the heart was performed in patients with known or suspected PAH.Results: The CS was identified in all 60 patients (mean +/- SD, 60.5 +/- 17.5 years; 45% men) without PAH (control group) (mean +/- SD, diameter 7.05 +/- 1.90 mm). In 24 patients (9 men; average age +/- SD, 54.1 +/- 14.5 years) with known or suspected PAH (study group), pulmonary artery (PA) pressures were increased; the CS was dilated (mean SD, 9.4 +/- 4.2 mm); and its size correlated with right atrial pressure (r = 0.358, P = 0.061), mean PA pressure (r = 0.568 P = 0.005), systolic PA pressure (r = 0.375, P = 0.071), and diastolic PA (r = 0.561, P = 0.004).Conclusion: The CS is routinely visualized and measurable on chest CT. In patients with PAH, CS dilation is associated with increased PA pressures.
