Unfractionated heparin (UFH) is frequently prescribed for children for the prevention and treatment of thrombosis; however, its safety and efficacy have not been assessed. The aim of this single center, prospective cohort study was to determine the incidence of major bleeding and recurrent thrombosis in children receiving UFH. Major bleeding was defined a priori as: central nervous system or re...

results: patients in the case and control groups were similar in age and admission vital signs. during the second operation, the bleeding volumes measured in the case and control groups were 66 ± 27.01 ml and 152 ± 85.4 ml, respectively. there was some pad-induced damage after the removal of the pad in the control group. patients and methods: twenty male patients with grade iv or v liver injuri...

results the hemostasis time for the ferric chloride concentration group was significantly less than for the control group (p < 0.001). materials and methods in this animal model study, 60 male wistar rats were used. an incision, 2 cm long and 0.5 cm deep was made on rat skin and the hemostasis time was recorded using ferric chloride at different concentrations (5%, 10%, 15%, 25%, and 50%) and t...

gastrointestinal stromal tumors (gist) are the most common mesenchy­mal tumors of the gastrointestinal tract. the biological pattern of these tumors ranges from benign-appearing small lesions to malignant sarcomas. only 3%-5% of gists are found in the duodenum. a duodenal gist is a rare source of upper gastrointestinal bleeding. a remarkable percentage of duodenal gists are localized in the thi...

To assess the feasibility of multi-detector computed tomography angiography (MDCTA) volumetry for quantification and grading acute non-cerebral, non-gastrointestinal bleeding. This retrospective, single-center study investigated consecutive patients with MDCTA positive active bleeding, between January 2020 June 2020. Outcome measures were extravasation at arterial parenchymal phase using measur...

A hepatic artery pseudoaneurysm is, by definition, a pulsatile hematoma due to a leakage of blood through a tear or disruption of the arterial wall, and the blood is contained only by the hepatic parenchyma or surrounding hematoma. It can be a very rare cause of gastrointestinal system bleeding. These pseudoaneurysms are usually very well managed by angiographic intervention. However, in some c...
