Omniflow II biyosentetik vasküler greftin alt ekstremite arteriyel revaskülarizasyonunda uzun dönem sonuçları

Amaç: Bu çalışmada tıkayıcı damar hastalığı olan hastalarda Omniflow II biyosentetik vasküler greftler ile femoropopliteal baypas işlemlerinin açıklık oranı ve uzun dönem sonuçları değerlendirildi. Çalışma planı: Bu retrospektif, gözlemsel, klinik çalışmaya periferik arter hastalığı nedeniyle Omniflow II biyosentetik vasküler greftlerin kullanıldığı femoropopliteal baypas yapılan toplam 93 hasta (61 erkek, 32 kadın; ort. yaş 56.9±7.4 yıl; dağılım, 43-83 yıl) alındı. Bu hastalar iki gruba ayrıldı: femoropopliteal diz üstü baypas yapılan 62 hasta ve femoropopliteal diz altı baypas yapılan 31 hasta. Ameliyat öncesi klinik özellikler, ameliyat sonrası greft açıklık oranları ve diğer klinik bulgular değerlendirildi. Bulgular: Ortalama takip süresi femoropopliteal diz üstü baypas grubunda 44.9±18.8 ay ve femoropopliteal diz altı baypas grubunda 47.3±22.3 ay idi (p=0.302). Üç, dört ve beşinci yıllarda femoropopliteal diz üstü baypas ve femoropopliteal diz altı baypas grubunda kümülatif primer greft açıklık oranları sırasıyla %98, %95 ve %78 ve %86, %75 ve %45 idi (log-rank; p=0.312). Beşinci yılda femoropopliteal diz üstü baypas ve femoropopliteal diz altı baypas grubunda kümülatif yardımlı greft açıklık oranları sırasıyla %87.9 ve %65.3 idi (log-rank; p=0.530). Sonuç: Omniflow II biyosentetik vasküler greft, femoropopliteal diz üstü ve diz altı baypas işlemlerinde kullanılabilir. Bu greftler yüksek açıklık oranları, düşük anevrizma ve enfeksiyon gelişim insidansı nedeniyle tercih edilebilir.

Long-term outcomes of Omniflow II biosynthetic vascular graft in lower extremity arterial revascularization

Background: This study aims to evaluate the patency rates and long-term outcomes of femoro-popliteal bypass procedures with Omniflow II biosynthetic vascular grafts in patients with occlusive vascular disease.Methods: This retrospective, observational, clinical study included a total of 93 patients (61 males, 32 females; mean age 56.9±7.4 years; range, 43 to 83 years) who underwent femoro-popliteal bypass in which Omniflow II biosynthetic vascular grafts were used due to peripheral arterial disease. The patients were divided into two groups: 62 patients undergoing femoro-popliteal above-knee bypass and 31 patients undergoing the femoro-popliteal below-knee bypass. We evaluated preoperative clinical characteristics, postoperative graft patency rates, and other clinical results.Results: The mean follow-up was 44.9±18.8 months in the femoro-popliteal above-knee bypass group and 47.3±22.3 months in the femoro-popliteal below-knee bypass group (p=0.302). The cumulative primary graft patency rates of the femoro-popliteal above-knee bypass and femoro-popliteal below-knee bypass groups at three, four, and five years were 98%, 95% and 78% and 86%, 75% and 45%, respectively (log-rank; p=0.312). The cumulative assisted graft patency rates of the femoro-popliteal above-knee bypass and femoro-popliteal below-knee bypass groups at five years were 87.9% and 65.3%, respectively (log-rank; p=0.530).Conclusion: The Omniflow II biosynthetic vascular graft is suitable for above- and below-knee femoro-popliteal bypass procedures. These grafts may be prefered due to high patency rates, low incidence of aneursym formations, and infections.
