Feasibility to obtain vessel occlusion using vessel loop

This ex-vivo study evaluated the tensile strength required for vascular occlusion using vessel loops on human femoral arterie and porcine aortic arteries. Temporary vascular occlusion is critical in many interventions, yet research on the tensile strength needed for effective occlusion with vessel loops is limited. Using an electronic-mechanical instrument, tensile strength in grams was measured across various sizes of Dormoloop vessel loops. The study compared the Potts loop and Rummel tourniquet techniques, revealing significant differences in the tensile strength required for occlusion. The Potts loop technique required a mean tensile strength of 305.75 g (± 106.07), while the Rummel tourniquet technique required 564.50 g (± 139.81), with a statistically significant difference (p = 0.027). All experiments achieved flow occlusion, demonstrating that the Potts loop technique requires less tensile strength, potentially resulting in less trauma during occlusion. These findings suggest that the choice of occlusion technique can impact the tensile force needed, with clinical implications that warrant further investigation, including studies with larger sample sizes and microscopic analyses to assess tissue trauma.
