Successful Nonsurgical Treatment of Acute Peritonitis Caused by a Large Thrombosis of the Superior Mesenteric Vein in a 25-year-old Woman.

Superior mesenteric venous thrombosis (SMVT), which results from various etiologies, including coagulation disorders, can be diagnosed early using advanced imaging technology. However, few reports have described the nonsurgical treatment of acute peritonitis caused by SMVT. We encountered a young woman whose history included abdominal pain and daily oral contraceptives and who presented with acute peritonitis caused by SMVT.

Association between changes in platelet reactivity during elective percutaneous coronary intervention and periprocedural myocardial infarction: A pilot study.

Background: High platelet reactivity before percutaneous coronary intervention (PCI) reportedly increases the risk of PCI-related myocardial infarction (PMI) following elective PCI. We conducted a pilot study to evaluate changes in platelet reactivity during PCI and their association with the incidence of PMI.

Methods: In total, 133 consecutive patients undergoing elective PCI after pretreatment with dual antiplatelet therapy for at least 7 days were prospectively enrolled.
