PurposeTo observe the therapeutic effect of interventional embolization and haemorrhage control in multiple trauma patients with a major abdominal or pelvic injury.MethodsData of 160 multiple trauma patients with a major abdominal or pelvic injury were retrospectively analyzed. They were admitted into the Department of Emergency of the First Affiliated Hospital of Zunyi Medical College from October 2013 to April 2016. Eighty-seven patients who received emergent intervention for embolization and haemorrhage control were set as group A, including 72 males and 15 females, with an average age of (39.32 ± 14.0) years. Patients underwent emergent intervention for embolization and hemostasis. The other 73 patients who received traditional surgeries were set as group B, including 62 males and 11 females, with an average age of (38.48 ± 13.12) years. The time from admission to emergency intervention, the time of interventional embolization, transfusion during hospitalization, length of stay and prognosis were observed. The whole treatment and prognosis were compared between group A and group B.ResultsIn group A, the average time from admission to intervention exploration was (132.05 ± 86.80) min, the average operation time was (149 ± 49.69) min, the average hospitalization time was (18.37 ± 4.71) days, the average amount of RBC transfusion during hospitalization was (7.2 ± 4.33) units, and the mortality was 4.60% (4 patients died). The corresponding data in group B were respectively (138.95 ± 82.49) min, (183 ± 52.39) min, (22.72 ± 6.63) days, (12.23 ± 5.43) units, and 9.59% (7 cases died). There was no statistical difference in the time from admission to operation between the two groups (p > 0.05), but there was statistical difference in operation time, RBC transfusion, hospitalization time, prognosis, and mortality between the two groups (all p < 0.05).ConclusionThe emergent intervention for embolization and haemorrhage control of multiple trauma patients with a major abdominal or pelvic injury and visceral organ haemorrhage has the advantages of less trauma, shorter operation time, shorter hospital stay, less blood transfusion in comparison to the traditional emergency surgeries.

The transarterial embolization procedures have been perfo rmed in a total 01 38 patients with head and neck lesions, includ in g 5 carotid-cavernous list비 as ， 1 internal carotid aneurysm, 10 meningiomas, 16 nasopharyngeal angiolibromas, 1 post-traumatic epistaxis and 5 other vascular tu mo rs, over the 18 months period. Six cases 01 C-C listulas and ICA aneurysm were treated with the detachable bal loon catheter techniqueThe men in gio mas, angiolibromas and all other lesions were embolized with superselection 01 the branches 01 the external carotid arte 마 such as the internal maxillary, the middle men ingeal, the ascending pharyngeal, the lacial or other branches, using Berenstein superselective cathete rs or conventional angiograph ic cathetersThe PVA (po lyvinyl alcohol loam) and/or Gelloam particles we re used as embolic materials in t hese cases
