Infections in the groin may be avoided by performing arterial bypass&nbsp; tenneling via the obturator foramen during lower extremity revascularization. This study aimed to evaluate the safety and efficacy of extra-anatomical bypass obturator in patients with groin infection.</span></span></span></span></span></span></span></span><br> <span style="font-size:13pt"><span style="text-justify:kashida"><span style="text-kashida:0%"><span style="text-autospace:none"><span new="" roman="" style="font-family:" times=""><span style="font-style:italic"><span style="font-size:9.0pt"><span style="font-style:normal">&nbsp;&nbsp; <b>Methods:</b> This cohort included a convenient sample of 100 patients with groin infections who planned to do an extra-anatomical obturator bypass. All patients were subjected to history taking and clinical assessment. Ultrasonography with duplex screening is a good initial technique to assess groin masses. Combination of computed tomography (CT) or magnetic resonance imaging (MRI) with indium-labeled leucocyte scintigraphy can also play a role in the diagnosis.</span></span></span></span></span></span></span></span><br> <span style="font-size:13pt"><span style="text-justify:kashida"><span style="text-kashida:0%"><span style="text-autospace:none"><span new="" roman="" style="font-family:" times=""><span style="font-style:italic"><span style="font-size:9.0pt"><span style="font-style:normal">&nbsp;&nbsp; <b>Results:</b> Inflow from the already-existing graft limb was used in 54% of obturator canal bypass (OCB) procedures, with 32 limbs coming from the main iliac (27.3%) and 6 limbs from the infrarenal aorta (5.1%). The distal superficial femoral artery was used in 21 limbs (17.9%), while the above-knee popliteal artery was selected as the outflow artery in 82% of cases. Primary aided patency was 68% at 24 months, according to Kaplan-Meier analysis, whereas primary patency was 63% at that time. At 24 months, the secondary patency of the OCB was 83%.</span></span></span></span></span></span></span></span><br> <span style="font-size:13pt"><span style="text-justify:kashida"><span style="text-kashida:0%"><span style="text-autospace:none"><span new="" roman="" style="font-family:" times=""><span style="font-style:italic"><span style="font-size:9.0pt"><span style="font-style:normal">&nbsp;&nbsp; <b>Conclusion:</b> In case of groin infections, an excellent option to restore flow is an obturator bypass graft. This graft is strong, reliable, and safe. As a result of its high patency rate, it may be the first choice in certain circumstances.</span></span></span></span></span></span></span></span><br> &nbsp; Groin Infections, Obturator Bypass, Extra-anatomical Bypass 516 521 http://mjiri.iums.ac.ir/browse.php?a_code=A-10-8097-1&slc_lang=en&sid=1 Mahmoud Mohammed Moawed moawedsurgeon@yahoo.com 200319475328460077802 200319475328460077802 Yes Department of Vascular Surgery, Damietta Faculty of Medicine, Al-Azhar University, Damietta, Egypt Salah Mohammed Abd-Elghany drsalah.plastic@mail.com 200319475328460077803 200319475328460077803 No Department of Plastic Surgery, Damietta Faculty of Medicine, Al-Azhar University, Damietta, Egypt
