Feasibility study of emergency intervention for vascular injury outside the hospital

Abstract

BackgroundMinimally invasive surgery in the field of traumatic vascular injury diagnosis and treatment has achieved good results. This study was designed to determine whether pre-hospital emergency intervention is feasible for vascular injury in a field intervention cabin under the condition of war or a disaster site.MethodsDifferent types of animal experiments of vascular injury intervention were performed in a field intervention cabin. Treatment capacity was evaluated by data collection, including duration of surgery, clinical evaluation, image clarity, and equipment handling. Environmental adaptability and mobility were evaluated by maneuverability and long-distance mobility.ResultsA total of 56 surgeries (7 types) were performed in the field intervention cabin. Digital subtraction angiography (DSA) had good imaging performance. A total of 4800 km of long-distance mobility was performed, and all the equipment operated normally without any equipment failure. We participated in the medical service maneuver twice. The cabin unfolded and worked properly. There was no equipment damage during the medical service maneuver.ConclusionsUse of a field intervention cabin under the conditions of war or disaster is feasible for pre-hospital emergency intervention of vascular injury.

Novel magnetic silk fibroin scaffolds with delayed degradation for potential long-distance vascular repair

“…Treatment for long-distance (≥10 mm) vascular injury (LDVJ) is a challenge in clinical surgery due to the complexity of the vascular network and the pathological fibrosis caused by the long repair period [ [1] , [2] , [3] , [4] , [5] ]. Currently, vascular scaffold is one of the effective therapies for LDJV [ 6 , 7 ], which can promote the formation of vascular endothelium and the deposition of extracellular matrix [ [8] , [9] , [10] ].…”
