ACPO in the setting of an acute pulmonary embolism and embolic stroke is a rarity. A 76-year-old female with shortness of breath, left hemiparesis and right-sided paresthesias presented with acute pulmonary embolism and acute infarcts of the left caudate nucleus, thalamus and occipital lobe.

文摘The distention of the colon without mechanical or anatomical obstruction, Acute Colonic Pseudo-obstruction (ACPO), is a common condition occurring in the critically ill. ACPO in the setting of an acute pulmonary embolism and embolic stroke is a rarity.

文摘目的探讨脑卒中急性期动态血压的变化及血压与预后的相关性。方法本研究分别对发病48 h内入院的53例脑梗死和38例脑出血患者进行24 h动态血压监测,持续10 d,并记录其他影响预后的危险因素及21 d、3个月的神经功能评分。结果脑卒中急性期血压升高的发生率为74．7%,入院4 d内血压下降显著,4～10 d时血压下降趋于平缓。多因素Logistic回归分析显示,脑卒中急性期收缩压升高是近期预后不良(OR=1．071,1．018～1．127,P =0．008)及远期(OR=1．040,1．010～1．071,P=0．009)预后不良(MRS≥3)的危险因素,对近期死亡无明显影响(OR=0．988,0．920～1．062,P=0．750)。亚组分析结果显示:脑梗死患者急性期血压与近、远期预后呈U型曲线关系,最适血压水平:收缩压140～160 mm Hg、舒张压75～80 mm Hg。经调整其他预测因子,收缩压≥160 mm Hg与140～159 mm Hg相比是近期(多因素Logistic回归分析,OR=4．682,1．23～17．823,P=0．024)和远期(OR=2．372, 1．188～4．735,P=0．014)预后不良的独立危险因素;脑出血患者急性期血压升高是近期死亡(多因素Logistic回归分析,OR=1．212 1．019～1．442 P=0．03)及远期(OR=1．27 1．019～1．583 P=0．033)预后不良的独立危险因素。结论脑卒中急性期血压升高常见,但血压有自调下降的趋势;脑梗死患者急性期收缩压≥160 mm Hg与预后不良呈显著相关,脑出血急性期血压升高是预后不良的独立危险因素。
