Splenik arter psödoanevrizmasında acil endovasküler tedavi

Amaç: Splenik arter psödoanevrimaları (SAPA) nadir görülen ancak rüptüre olduğunda yüksek mortalite oranı olan akut batın nedenlerindendir. Travma sonrası splenik arterde yaralanma ve aktif kanamanın olması da mortalitesi yüksek ve acil tedavi gerektiren bir durumdur. Çalışmamızın amacı SAPA’larda ve splenik arter yaralanmalarında endovasküler tedavinin etkinliğini kendi tecrübemiz ve literatür bilgileri eşliğinde tartışmaktır. Gereç ve Yöntem: 2002-2016 tarihleri arasında çeşitli nedenlerle kontrastlı bilgisayarlı tomografi ile SAPA tanısı konan 3’ü kadın, 6’sı erkek toplam 9 hastanın endovasküler tedavileri yapıldı. Endovasküler tedavi splenik arter veya anevrizmanın platin mikrosarmallarla embolizasyonu (n=8) veya kaplı stent implantasyonu (n=1) şeklinde gerçekleştirildi. Bulgular: Dokuz hastanın %33.3’u kadın (n=3), %66.7’i erkek (n=6), ortalama yaşları 44.8 (23-66 yaş) idi. En sık semptom gastrointestinal kanama olup tüm hastalarda mevcuttu. SAPA nedenleri; travma (n=5), iyatrojenik (n=2), ve akut pankreatit (n=2) idi. Hastaların bilgisayarlı tomografi ve dijital substraksiyon anjiyografisinde psödoanevrizma (PA) (n=9) ve bir hastada splenik arterde PA'ya ek olarak splenik arter ve ven arası fistül (AVF) de gözlendi. Yedi hasta splenik arter embolizasyonu [parent arter oklüzyonu (PAO)] yapıldı, diğer 2 hasta kaplı stent ve koilleme ile tedavi edilmiştir. Tedavi sonrası sonuçlar iyi olup takip periyodunda (1 ay-14 yıl) komplikasyon gözlenmedi. Sonuç: SAPA nadir ancak ölümcül sonuçlar doğurabilen akut batın nedenleri olup endovasküler yöntemlerle tedavileri güvenlidir ve iyi sonuçlar vermektedir.

Emergency endovascular treatment in splenic artery pseudoaneurym

Aim: Although splenic artery pseudoaneuryms (SAPA) are rare cause of acute abdomen, when they rupture they have high mortality rates. Posttraumatic splenic artery injury and/or active bleeding have also high mortality rates and they require immediate treatment. In our study we aim to discuss the endovascular treatment option for SAPA with our experience and literature. Materials and Methods: Between 2002-2016 there were 9 patients (6 male,3 female) who had endovascular treatment for SAPA diagnosed with abdominal CT. Endovascular treatment options were platinum coil embolization (n=8) or covered stent implantation (n=1). Results: Mean age for 9 patients (6 male, 3 female) was 44.8 (in the range between 23-66 years). The only clinical symptom was massive gastrointestinal bleeding (9 patients). Etiologies for SAPAs were; trauma (n=5), iatrogenic (n=2) and acute pancreatitis (n=2). From CT scans and angio images there were pseudoaneurysms (PA) (n=9) and in one patient there were both PA and splenic arterio-venous fistula (AVF) between splenic artery and vein. Seven patients were treated with splenic artery embolization [parent artery occlusion (PAO)]. Other two patients with PA were treated with PA coiling and covered stent implantation. After treatment, results were good and in follow-up period (1-14 months) no complications were occured. Conclusion: Splenic artery injury is rare cause of acute abdomen with high mortality rate, and it can be treated safely with endovascular technics with good results.
