Abstract

Purpose: The purpose of this retrospective study was to evaluate the technical success and clinical outcomes of endovascular procedures and to compare them with the surgical procedures of subclavian artery occlusive diseases.

Material and Methods: Between 1994 and 2009, 37 patients with clinical symptoms secondary to subclavian artery stenoses and/or occlusion were diagnosed by color Doppler ultrasound (CDUS) or Digital Subtraction Angiography (DSA). 14 (37.8%) of these patients were female and 23 (62.2%) were male; mean age was 56.4 (arange 22-82). 38 lesions were treated with balon anjioplasty and/or stent placement. After treatment, patients’ follow-ups were performed by CDUS and clinically.

Results: 32 (84.2%) of lesions were found on the left and 6 (15.8%) were on the right side. Technical success rate for stenotic lesions was 100%. We couldn’t achieve to pass through 3 occlusions and so the technical success rate for occlusions was 57%. As a complication, in one patient during the procedure thrombotic occlusion in the proximal segment of subclavian artery and extravasation in the mid segment were encountered. Another stent and a stent graft were used to treat these complications. In another patient, because of distal thromboembolic occlusions, 5 mg t-PA infusion for 1.5 hour was applied and recanalisation was obtained. For early (0-3 months) and mid (3-6 months) terms primary and secondary patency rate was 100%. We found primary patency rate 95.5% and secondary patency rate 100% for late term (6-12 months).

Conclusion: Endovascular treatment of subclavian artery occlusive diseases is technically and clinically effective and safe procedure and alternative to surgery.

Subklavyen arter tıkayıcı hastalıklarında endovasküler tedavinin etkinliği

Abstract

Amaç: Bu retrospektif çalışmanın amacı, subklavyen arter
tıkayıcı hastalıklarında endovasküler tedavinin başarısını ve klinik
sonuçlarını değerlendirmek ve bu sonuçları cerrahi tedavi yöntemleri ile
karşılaştırmaktır.

Gereç ve Yöntem: 1994-2009 yılları arasında mevcut klinik
semptomları ile  görüntüleme yöntemleri renkli Doppler ultrasonografi
(RDUS), Dijital Subtraksiyon Anjiyografi (DSA) sonrasında subklavyen arter
stenozu ve/veya oklüzyonu saptanan 14’ü (%37,8) kadın, 23’ü (%62,2) erkek olan
ve yaşları ortalama 56,4 (22 ile 82 yıl arasında değişen) 37 hastada mevcut 38
lezyona balon anjiyoplasti ve/veya stent implantasyonu ile endovasküler tedavi
uygulandı. Tedavi sonrasında hastaların kontrolleri önceden planlanmış sürelerde
klinik ve RDUS ile takipleri yapıldı.

Bulgular: Lezyonların 32’si sol (%84,2), 6’sı sağ (%15,8)
yerleşimliydi. Olguların 7’si (%18,4) oklüzyon, 31’i (%81,6) stenoz idi. Stenoz
oranı RDUS’de %50’den fazla, DSA’da ise ortalama %83,2 idi. Stenotik lezyonlar
için teknik başarı %100 idi. Oklüde olan 3 lezyon geçilemediği için bu
hastalara endovasküler tedavi yapılamadı. Bu nedenle oklüzyonlar için teknik
başarı %57 idi. Komplikasyon olarak işlem sırasında bir hastada ekstravazasyon
ve subklavyen arter proksimalinde trombotik oklüzyon gelişmesi üzerine
ekstravazasyon mevcut segmente stent greft ve proksimaldeki oklüzyona ayrı bir
stent implantasyonu yapıldı. Bir hastada ise distal embolizasyon gelişmesi
üzerine 1,5 saat boyunca 5 mg t-PA infüzyonu yapıldı ve rekanalizasyon
sağlandı. Takibi yapılabilen hastalarda erken (0-3 ay) ve orta (3-6 ay) dönem
için primer ve sekonder patensi oranı %100 iken geç (6-12 ay) dönem için primer
patensi %95,5, sekonder patensi ise %100 olarak bulundu.

Sonuç: Subklavyen arter tıkayıcı hastalıklarında
endovasküler tedavi teknik ve klinik olarak cerrahi tedaviye alternatif etkin
ve güvenli bir yöntemdir.
