【摘要】：目的研究冠狀動脈支架置入后心肌脂肪浸潤的雙源CT表現(xiàn)。方法回顧性分析行雙源CT冠狀動脈造影的患者160例,分析冠狀動脈支架置入后心肌脂肪浸潤的分布特征,并評估部分病例的左心室首過灌注功能。結果 160例患者中,有心肌脂肪浸潤者24例;有8例患者多支血管置入了支架;16例患者單支血管置入支架,包括左前降支11例,右冠狀動脈1例,回旋支4例。支架置入年限為0.8~15(5.4±3.4)年。心肌脂肪浸潤主要位于支架遠端心肌,表現(xiàn)為局部心肌強化減低、心室壁變薄,而且心肌脂肪浸潤區(qū)域出現(xiàn)灌注減低。選取6例心肌脂肪浸潤患者和27例無脂肪浸潤患者進行左心室首過灌注功能比較,發(fā)現(xiàn)支架植入后心肌脂肪浸潤患者心搏出量、舒張末期容積明顯高于無脂肪浸潤者(P均0.05)。結論冠狀動脈支架置入后心肌脂肪浸潤一般好發(fā)于支架遠端心肌,同時伴有心臟功能異常。雙源CT對冠狀動脈支架置入后心臟可同時提供形態(tài)學和功能學信息。
[Abstract]:Objective to study the dual-source CT findings of myocardial fat infiltration after coronary stenting. Methods the distribution of myocardial fat infiltration after coronary stenting was analyzed retrospectively in 160 patients who underwent double source CT coronary angiography. Results among 160 patients, 24 had myocardial fat infiltration, 8 patients had multiple vessels and 16 patients had single vessel stents, including 11 patients with left anterior descending branch. Right coronary artery (1 case), circumflex branch (4 cases). Stent placement was 0.8155.4 鹵3.4 years. Myocardial fat infiltration was mainly located in the distal myocardium of the stent, which was characterized by decreased local myocardial enhancement and thinning of ventricular wall. The left ventricular first-pass perfusion was compared in 6 patients with myocardial fat infiltration and 27 patients without fat infiltration, and the cardiac output was found in the patients with myocardial fat infiltration after stent implantation. The end diastolic volume was significantly higher than that in the patients without fat infiltration (P < 0.05). Conclusion Myocardial fat infiltration after coronary stent implantation is more common in the distal end of the stent than that in the distal end of the stent. Dual-source CT can provide both morphological and functional information after coronary stent implantation.
