Introduction. Femoro-femoral crossover bypass is an extraanatomic reconstruction used for revascularization of lower limb with contralatateral femoral artery as an inflow vessel, and the graft placed in the suprapubic region. We perform this procedure when anatomic reconstruction is not possible or is contraindicated. Objective. To analyze the influence of different risk factors on early patency of femoro-femoral crossover bypass. Methods. This retrospective study analyzed the results of 88 femoro-femoral bypass grafting during an 11-year period. There were 66 (75%) males and 22 (25%) females of average age 64.93 years (42-79 years). In 76 patients the operations were performed due to critical limb ischemia. Revascularization was urgent in 12 patients, while 76 patients were elective. Dacron prosthesis was used in 81 patients, while PTFE was used in 7 patients. Statistical analysis was made by logistic regression. Results. During hospitalisation the graft remained patent in 82 patients, and graft thrombosis occurred in 6 patients. Limb salvage rate was 90.91%. Early morbidity rate (within the first post-operative month) was 13.64%, while early mortality rate was 4.55%. Using logistic regression we established that early graft patency was statistically more significant in males (p<0.05). Age (p=0.07) and hypertension (p=0.08) appeared to be predicting influence of the graft patency on the border of the accepted statistical significance level. Conclusion. Femoro-femoral crossover bypass is a good alternative for revascularization in high risk patients for standard anatomic reconstructions due to comorbid conditions or local problems.
