Kronik Total Oklüde Superior Mezenter Arterin Perkütan Yolla Revaskülarizasyonu
Özet
Kronik mezenterik iskemi, mezenterik arterlerde gelişen aterosklerotik darlık veya oklüzyon sonucu intestinal dolaşımın metabolik gereksinimleri karşılayamaması ile ortaya çıkan, tanısı sıklıkla geciken ancak tedavi edilmediğinde ciddi morbidite ve mortaliteye neden olabilen önemli bir vasküler hastalıktır. Günümüzde endovasküler revaskülarizasyon, daha düşük periprosedürel komplikasyon oranları nedeniyle birçok merkezde öncelikli tedavi seçeneği haline gelmiştir. Bu bölümde, postprandiyal karın ağrısı ve belirgin kilo kaybı yakınmaları ile başvuran 73 yaşındaki kadın hastada izole superior mezenterik arter kronik total oklüzyonuna yönelik başarılı perkütan endovasküler tedavi sunulmaktadır. Sağ brakiyal arter yaklaşımı ile gerçekleştirilen işlemde, farklı kılavuz tel stratejileri sonrasında lezyon başarıyla geçilmiş, predilatasyon sonrası stent implantasyonu uygulanarak tam revaskülarizasyon sağlanmıştır. İşlem sırasında komplikasyon gelişmemiş, takipte hastanın abdominal semptomlarında belirgin düzelme ve kilo alımı gözlenmiştir. Bu olgu, uygun hasta seçimi ve dikkatli teknik planlama ile kompleks superior mezenterik arter kronik total oklüzyonlarında endovasküler tedavinin güvenli ve etkili bir seçenek olduğunu göstermektedir.
Chronic mesenteric ischemia is an important vascular disease characterized by the inability of the intestinal circulation to meet metabolic demands due to atherosclerotic stenosis or occlusion of the mesenteric arteries. Although the diagnosis is frequently delayed, if left untreated, it may lead to serious morbidity and mortality. Nowadays, endovascular revascularization has become the preferred treatment option in many centers because of its lower periprocedural complication rates. In this chapter, we present a successful percutaneous endovascular treatment of isolated chronic total occlusion of the superior mesenteric artery in a 73-year-old female patient who presented with postprandial abdominal pain and significant weight loss. During the procedure, which was performed via a right brachial artery approach, the lesion was successfully crossed after the use of different guidewire strategies, followed by predilatation and stent implantation, resulting in complete revascularization. No procedural complications occurred, and follow-up revealed significant improvement in the patient’s abdominal symptoms along with weight gain. This case demonstrates that endovascular treatment is a safe and effective option in complex chronic total occlusions of the superior mesenteric artery when appropriate patient selection and careful technical planning are applied.
