[A novel method of endovascular aneurysm sealing (EVAS) in patients with abdominal aortic aneurysm]. / Nová metoda endovaskulární výplne výdute aorty abdominální (endovascular aneurysm sealing EVAS).

INTRODUCTION: Endovascular stent graft therapy of abdominal aortic aneurysms is sometimes complicated due to unusual anatomy of the aorta and adjacent arterial regions, an irregular or short proximal neck, numerous patent branches originating from the aneurysm, or tortuous iliac arteries. Endovascular aneurysm sealing is a new method designed to overcome certain limitations of current stent grafts. METHOD: At the Department of Vascular Surgery of Na Homolce Hospital, we implanted 51 stent grafts in the subrenal aorta and iliac arteries. Most of them were regular bifurcated stent grafts. Two patients were treated with the new Nellix stent graft, in one case due to a short subrenal neck of only 13 mm, and due to a considerably conical neck in the second case. RESULTS: The post-operative course was uneventful in both patients and they were discharged on the 5th postoperative day. CT angiography after six weeks proved that the stent graft had sealed well. The polymer filled the aortic lumen completely. CONCLUSION: This new method of endovascular aneurysm sealing (EVAS) of abdominal aortic aneurysm makes it possible to treat patients whose anatomy would normally require technically complex and more expensive endovascular methods. We aim to follow long-term results of the method in larger patient cohorts.

[Prevention of type II endoleak using postoperative coiling of the abdominal aortic aneurysm sac during stent graft implantation]. / Prevence endoleaku II. typu pomocí peroperacního coilingu vaku aneuryzmatu abdominální aorty behem implantace stentgraftu.

AIM: A prospective randomized study assessing the success rates of type II endoleak (EL) prevention, using postoperative coiling of the abdominal aortic aneurysm (AAA) sac during stent graft (SG) implantation. MATERIAL AND METHODS: From January 2008 to July 2009, 86 patients were operated for AAA using endovascular methods with bifurcation SG. The subjects were prospectively randomized into two subgroups. Group A subjects (42 subjects; 48.8%) had various numbers of coils introduced into the sac, close to the SG body. Group B (44 subjects; 51.2%) included patients without coils. Preoperative CT angiograhy (CT AG) was used to assess patency and the number of lumbal arteries (AL), a.mesenterica inferior (AMI), a. sacralis mediana (ASM) and aa. renales accessoriae (ARA), the AAA sac and the lumen size. At the end of the studied period, existence of type II EL and the AAA sac size was assessed using sonography and /or CT AG. RESULTS: Prior to the procedure, there were only minor differences in the number of source type II EL arteries (AL 3.8 vs. 3.5; AMI 0.78 vs. 0.55; ASM 0.26 vs. 0.3; ARA 0.095 vs. 0.05), preoperative AAA sac size (68.6 vs. 67.0 mm) and the lumen size (47.6 vs. 40.0 mm), the AAA sac size at the end of the studied period (63.9 vs. 62.1 mm) and its mean size change (-4.7 vs. -4.9 mm), between the Group A and B, respectively . Postoperatively, the type II EL was detected in 6 subjects in Group A (14.3%), and in 9 subjects in Group B (20.5%). At the study endpoint, the type II EL was identified in 4 subjects in Group A (9.5%), in 8 subjects in Group B (18.2%). CONCLUSION: Peroperative introduction of coils into the AAA sac is one of the options for type II EL prevention. It facilitates successful regression and disappearance of type II EL.

[Embolic complication of the postcathetrization femoral artery pseudoaneurysm treatment using percutaneous thrombotization. A case review]. / Embolická komplikace lécby poskatetrizacního pseudoaneuryzmatu arteria femoralis perkutánní trombotizací. Kazuistika.

Considering frequencies of the heart cathetrization procedures, including treatment of pseudoaneurysms of the femoral artery using percutaneous thrombotization, a possibility of peripheral arterial emobolization should be considered. The authors describe management of the relatively rare complication in the treatment of postcathetrization pseudoaneurysms. According to the case review, clearing the obliterating arterial embolus of the tissue glue is technically feasible even more than 24 hours folowing the embolization.
