Risk factors for massive bleeding based on angiographic findings in patients with placenta previa and accreta who underwent balloon occlusion of the internal iliac artery during cesarean section.

Risk factors for massive bleeding based on angiographic findings in patients with placenta previa and accreta who underwent balloon occlusion of the internal iliac artery during cesarean section. Br J Radiol. 2019 Jul 18;:20190127 Authors: Tokue H, Tokue A, Tsushima Y, Kameda T Abstract OBJECTIVES: We evaluated the risk factors for massive bleeding based on angiographic findings in patients with placenta previa and accreta who underwent balloon occlusion of the internal iliac artery (BOIA) during cesarean section. METHODS: We performed a retrospective analysis using the clinical records of 42 patients with placenta previa and accreta who underwent BOIA during cesarean section between 2006 and 2017 in our institution. We reviewed incidence of collateral arteries to the uterus on the initial aortography. We evaluated the visualization of the ovarian artery arising directly from the abdominal aorta, round ligament artery arising from the external iliac artery/inferior epigastric artery, and the ilio-lumbar artery. In addition, the clinical characteristics were reviewed. Patients with an estimated blood loss during delivery of>2500 ml,>4 packed red blood cell transfusions, uterine artery embolization after delivery, or hysterectomy were defined as the massive bleeding group. We compared between the massive and non-massive bleeding groups. RESULTS: Twenty patients (48%) had a massive bleeding. No procedure-related severe complications w...

ConclusionsThe key determinants of the Bleeding Ratio among anticoagulated AF patients are age, prior thromboembolic and bleeding episodes. The study could support identification of AF patients who need additional effort to increase their acceptance of a life-long OAC therapy.

Authors: Iyer KS, Dayal S Abstract Platelets are small, anucleated effector cells that play an important role in linking the hemostatic and inflammatory processes in the body. Platelet function is known to be altered under various inflammatory conditions including aging. A gain in platelet function during aging can increase the risk of thrombotic events, such as stroke and acute myocardial infarction. Anti-platelet therapy is designed to reduce risk of serious cerebrovascular and cardiovascular events, but the adverse consequences of therapy, such as risk for bleeding increases with aging as well. Age-associated co...

Conclusion. Both ACF and PCF showed significant clinical improvement of radiculopathy. In the ACF group, the DH decreased, and CL decreased during the early postoperative period. Radiological parameters were preserved in the PCF group after surgery. However, this group showed greater intraoperative bleeding and revision rates. Care should be taken to manage complications according to the specific surgical treatment. Level of Evidence: 3

Objectives: We aimed to describe changes over time in admissions and outcomes, including length of stay, discharge destinations, and mortality of cirrhotic patients admitted to the ICU for variceal bleeding, and to compare it to the outcomes of those with other causes of ICU admissions. Design: Retrospective analysis of data captured prospectively in the Australian and New Zealand Intensive Care Society Centre for Outcome and Resource Evaluation Adult Patient Database. Settings: One hundred eighty-three ICUs in Australia and New Zealand. Patients: Consecutive admissions to these ICUs for upper gastrointestinal b...
