AI Summary & Key Takeaways
AI InsightThe primary patency rates at 6 and 12 months were significantly higher in the pharmacomechanical treatment group than the surgical group (85% vs. 67% and 78% vs. 55%, respectively; p<0.05).Conclusion:Pharmacomechanical thrombectomy procedure yields higher primary patency rates than open surgical thrombectomy for thrombosed native arteriovenous fistula.Keywords:Arteriovenous fistula, endovascular intervention, thrombosis.

Abstract
Background:This study aims to compare success and patency rates of pharmacomechanical thrombectomy versus open surgical thrombectomy for thrombosed native arteriovenous fistulas.Methods: A total of 96 patients (56 males, 40 females; mean age 61±11.7 years; range, 26 to 82 years) with a thrombosed native arteriovenous fistula between January 2016 and December 2018 were retrospectively analyzed. The patients were divided into two groups as pharmacomechanical thrombectomy (n=42) and open surgical thrombectomy (n=54). Primary failure rate and primary patency rate at 6 and 12 months were recorded.Results:Of 42 patients in the pharmacomechanical thrombectomy group, 41 (98%) had additional interventions, and primary failure occurred in four patients (10%). Primary failure was seen in 15 (28%) patients in the surgical group. The primary patency rates at 6 and 12 months were significantly higher in the pharmacomechanical treatment group than the surgical group (85% vs. 67% and 78% vs. 55%, respectively; p<0.05).Conclusion:Pharmacomechanical thrombectomy procedure yields higher primary patency rates than open surgical thrombectomy for thrombosed native arteriovenous fistula.Keywords:Arteriovenous fistula, endovascular intervention, thrombosis.
Özet
Amaç: Bu çalışmada nativ arteriyovenöz fistül trombozunda farmakomekanik trombektomi ile açık cerrahi trombektominin başarı ve açıklık oranları karşılaştırıldı.Ç a l ı ş m a p l a n ı :Ocak 2016 - Aralık 2018 tarihleri arasında nativ arteriyovenöz fistül trombozu olan toplam 96 hasta (56 erkek, 40 kadın; ort. yaş 61±11.7 yıl; dağılım, 26-82 yıl) geriye dönük olarak incelendi. Hastalar farmakomekanik trombektomi (n=42) ve açık cerrahi trombektomi (n=54) olmak üzere iki gruba ayrıldı. Altı ve 12. ayda primer başarısızlık oranı ve primer açıklık oranı kaydedildi.Bul gu lar: Farmakomekaniktrombektomigrubundaki 42 hastadan, 41’ine (%98) ek girişim yapıldı ve dört hastada (%10) primer başarısızlık izlendi. Açık cerrahi grupta 15 hastada (%28) primer başarısızlık görüldü. Altı ve 12. ayda primer açıklık oranları, cerrahi gruba kıyasla, farmakomekanik grupta anlamlı düzeyde daha yüksek idi (sırasıyla, %67’ye kıyasla %85 ve %55’e kıyasla %78; p<0.05).S o n u ç :Nativ arteriyovenöz fistül trombozunda farmakomekanik trombektomi işlemi, açık cerrahi trombektomiye kıyasla, daha yüksek primer açıklık oranı sağlar.A n a h t a rs ö z c ü k l e r :Arteriyovenöz fistül, endovasküler girişim, tromboz.
