Endovascular treatment of abdominal aortic anastomotic pseudoaneurysm. The experience of two centers.
2012
INTRODUCTION: Abdominal aortic pseudoaneurysms are a rare but serious complication of aortic surgery. Treatment with traditional open surgery is associated with a high rate of perioperative mortality and morbidity. Endovascular treatment is less invasive and guarantees lower mortality and morbidity rates. The aim of this study was to evaluate the role of short-, medium- and long-term endovascular treatment of these pseudoaneurysms. MATERIALS AND METHODS: Over the past 10 years, 14 patients with abdominal aortic aneurysms, which developed after prior aortic surgery, underwent endovascular treatment involving implantation of an endoprosthesis at our institutions. Exclusion criteria were emerg…

Anastomotic Pseudoaneurysm Complicating Renal Transplantation: Treatment Options
2010
Introduction: Anastomotic pseudoaneurysm following renal transplantation is uncommon. Indications for repair, treatment options and outcomes remain controversial. Report: We present 6 renal transplant recipients with large anastomotic pseudoaneurysms. Five of the patients underwent open repair while one had a stent-grafting and delayed transplant nephrectomy for a ruptured pseudoaneurysm. A transplant nephrectomy was needed in all cases but one. Arterial reconstruction enabled limb salvage in all cases. One patient died of sepsis postoperatively. No patient presented late infection, failure of vascular reconstruction, nor pseudoaneurysm recurrence. Conclusions: Surgical excision of anastomo…
Hybrid Endograft Solution for Complex Iliac Anatomy
2010
The purpose of this study was to evaluate single-center results with selective use of Gore Excluder limbs (W.L. Gore & Associates, Flagstaff, AZ) in a Cook Zenith body (Cook Inc, Bloomington, IN) for elective endovascular abdominal aortic aneurysm (AAA) repair. A prospectively held database for patients with AAA, who were treated endovascularly between March 1999 and July 2008, was queried for patients treated with a Cook Zenith body and one or two Gore Excluder limbs. Indication, technical success, late limb occlusion, and disconnection were evaluated. From 276 patients who were treated with a Zenith body, 29 underwent repair with hybrid graft components with, in total, 41 Gore Exclud…
Classification of Chimney EVAR-Related Endoleaks: Insights from the PERICLES Registry
2017
Juxtarenal aortic aneurysms (JAAs) pose significant challenges for endovascular aneurysm repair (EVAR). A short or absent infrarenal neck typically excludes standard EVAR as a viable or reasonable treatment option. In this context, the use of chimney grafts (chEVAR) is gaining in popularity and applicability. These grafts are designed to course in the aortic lumen outside the main stent-graft to maintain normal perfusion to the involved target branches. As such, they may represent a promising and less resource-intensive option for management of JAAs. However, this technical strategy is not without challenges of its own, particularly the inevitable creation of “gutters” that result from the …
Iliac-femoral stent-graft infection after hybrid procedure redo: Case report
2021
Introduction Stent-graft infection in peripheral arteries is rare and potentially dangerous. The use of hybrid procedures, in complicated patients previously treated, involves an increase of infective risk especially in no collaborative patients. Presentation of case We report a case of rare stent-graft infection in a patient treated for a Rutherford IV Multiple Peripheral Arterial Disease (MPAD) involving the right iliac-femoral axis with stenosis on deep femoral artery due to a previously stenting procedure for Superficial Femoral artery (SFA) stenosis. The first simultaneous hybrid intervention consisted of an endovascular iliac stent-graft placement and a surgical common femoral patch a…
Endoluminal stent-graft relining of visceral artery bypass grafts to treat perigraft seroma.
2013
Purpose: To describe the endovascular treatment of intra-abdominal perigraft seromas associated with small-caliber expanded polytetrafluoroethylene (ePTFE) grafts. Case Reports: Two patients who underwent hybrid repair of thoracoabdominal aortic aneurysms in which renovisceral bypass grafts were implanted presented with large, symptomatic perigraft seromas. The 5- to 8-mm-diameter ePTFE bypass grafts believed to be involved in the seromas were successfully relined with self-expanding Viabahn stentgrafts in percutaneous procedures. The patients’ symptoms were relieved, and imaging follow-up (18 and 10 months, respectively) has shown near complete resorption of the seromas. Conclusion: It is …
A 12-Year Experience With Chimney and Periscope Grafts for Treatment of Type I Endoleaks.
2015
Purpose: To evaluate the midterm outcomes of chimney and/or periscope grafts (CPGs) in patients presenting type I endoleak after a previous endovascular aneurysm repair (EVAR). Methods: Between June 2002 and April 2014, 24 consecutive patients (mean age 73.9±9.2 years; 23 men) presenting a type I endoleak were addressed with CPGs to extend the proximal and/or distal landing zone and to maintain side branch perfusion. Indication for treatment was a type Ia endoleak in 23 (96%) patients and a type Ib endoleak in one. Median interval from the previous EVAR to endoleak treatment with CPGs was 52.2±48.9 months (range 0.2–179). All patients had proximal/distal landing zones precluding any standa…
A 15-Year Single-Center Experience of Endovascular Repair for Elective and Ruptured Abdominal Aortic Aneurysms
2016
Purpose: To evaluate the differences in technical outcomes and secondary interventions between elective endovascular aneurysm repair (el-EVAR) procedures and those for ruptured aneurysms (r-EVAR). Methods: Of the 906 patients treated with primary EVAR from September 1998 until July 2012, 43 cases were excluded owing to the use of first-generation stent-grafts. Among the remaining 863 patients, 773 (89.6%) patients (mean age 72 years; 697 men) with asymptomatic or symptomatic abdominal aortic aneurysms (AAAs) were assigned to the el-EVAR group; 90 (10.4%) patients (mean age 73 years; 73 men) were assigned to the r-EVAR group based on blood outside the aortic wall on preoperative imaging. Th…
Pęknięty tętniak aorty zstępującej - duże wyzwanie dla niedużego ośrodka chirurgii naczyniowej
2018
Pacjentka, lat 76, została skierowana do Uniwersyteckiego Szpitala Klinicznego w Opolu z powodu podejrzenia rozwarstwienia aorty wstępującej i tamponady osierdzia. Przy przyjęciu chora w stanie ogólnym skrajnie ciężkim, z objawami głębokiego wstrząsu, niestabilna hemodynamicznie oraz wentylowana mechanicznie. W wykonanym doraźnie badaniu angio-TK stwierdzono rozwarstwienie aorty zstępującej z pękniętym tętniakiem w jej środkowym i dolnym odcinku oraz duży krwiak lewej jamy opłucnowej. Ze względu na znaczną szerokość aorty zstępującej, nawet w jej początkowym odcinku oraz aorty brzusznej powyżej pnia trzewnego do zaopatrzenia tętniaka potrzebne są dwa elementy stentgraftów o średnicy 46 mm. …
