RESUMEN
Pseudoaneurysm and arteriovenous fistula can occur after iatrogenic trauma or penetrating injuries. Endovascular treatment is a minimally invasive method used to manage these complex vascular injuries. We have described the case of a 27-year-old male patient who had presented with progressively increasing pain and swelling of the left inguinal region after a gunshot injury 5 years earlier. The bell-bottom technique was used in a reversed fashion to exclude the pseudoaneurysm and treat the arteriovenous fistula, achieving symptom resolution without complications.
RESUMEN
PURPOSE: To Compare the extent and intensity of adhesions formed between the intra-abdominal organs and the intraperitoneal implants of polypropylene mesh versus polypropylene/polyglecaprone versus polyester/porcine collagen used for correction of abdominal wall defect in rats. METHODS: After the defect in the abdominal wall, thirty Wistar rats were placed in three groups (ten animals each) for intraperitoneal mesh implant: polypropylene group, polypropylene/polyglecaprone group, and polyester/porcine collagen group. The macroscopic evaluation of the extent and intensity of adhesions was performed 21 days after the implant. RESULTS: The polypropylene group had a higher statistically significant impairment due to visceral adhesions (p value = 0.002) and a higher degree of intense adherence in relation to polypropylene/polyglecaprone and polyester/porcine collagen groups (p value<0.001). The polyester/porcine collagen group showed more intense adhesions than the polypropylene/polyglecaprone group (p value=0.035). CONCLUSIONS: The intraperitoneal implantation of polypropylene meshes to correct defects of the abdominal wall caused the appearance of extensive and firm adhesions to intra-abdominal structures. The use of polypropylene/polyglecaprone or polyester/porcine collagen tissue-separating meshes reduces the number and degree of adhesions formed.
