101. A population-based cohort study examining the risk of abdominal cancer after endovascular abdominal aortic aneurysm repair. (Abstract)

A population-based cohort study examining the risk of abdominal cancer after endovascular abdominal aortic aneurysm repair. Endovascular aneurysm repair (EVAR) has increasingly been used as the primary treatment approach for abdominal aortic aneurysm (AAA). This study examined the hypothesis that EVAR leads to an increased risk of abdominal cancer within the radiation field compared with open AAA repair.The nationwide English Hospital Episode Statistics database was used to identify all (...) patients older than 50 years who received an AAA repair in 2005 to 2013. EVAR and open AAA repair groups were compared for the incidence of postoperative cancer using inverse probability weights and G-computation formula to adjust for selection bias and confounding.Among 14,150 patients who underwent EVAR and 24,645 patients who underwent open AAA repair, follow-up was up to 7 years. EVAR was associated with an increased risk of postoperative abdominal cancer (hazard ratio [HR], 1.14; 95% confidence

102. Variation in Surgical Treatment of Abdominal Aortic Aneurysms With Small Aortic Diameters in the Netherlands. (Abstract)

Variation in Surgical Treatment of Abdominal Aortic Aneurysms With Small Aortic Diameters in the Netherlands. To evaluate reasons to deviate from aneurysm diameter thresholds, and focus on the difference in how Dutch vascular surgical units (VSUs) perceive their deviation and their actual deviation.Guidelines recommend surgical treatment for asymptomatic abdominal aortic aneurysms (AAAs) with a diameter of at least 55 mm for men and 50 mm for women. We evaluate reasons to deviate from (...) reasons to deviate were concomitant large iliac diameter (91%) and saccular aneurysm (82%). The majority of the VSUs (77%) estimated their guideline deviation to be <5%. Eleven VSUs (25%) estimated their deviation concordant with their DSAA percentage, but 75% of VSUs underestimated their deviation.Dutch VSUs regularly deviate from the guidelines regarding aneurysm diameter, with variation between VSUs. Consensus exists amongst VSUs on acceptable reasons for guideline deviations; however, the majority

104. Abdominal Aortic Aneurysm Caused by Aortic Fibromuscular Dysplasia: A Case Report Full Text available with Trip Pro

Abdominal Aortic Aneurysm Caused by Aortic Fibromuscular Dysplasia: A Case Report Fibromuscular dysplasia (FMD) mainly develops in medium-sized arteries, including renal, extracranial, and extremity arteries, but it rarely causes abdominal aortic aneurysm (AAA). A 69-year-old woman with AAA diagnosed on ultrasonography by a home doctor visited our hospital. Contrast-enhanced computed tomography revealed a saccular aneurysm of terminal abdominal aorta. We performed abdominal aortic replacement (...) and resected the section with aneurysm. Pathological examination of the wall tissue of the resected aneurysm revealed findings that are consistent with FMD. We report this case of AAA caused by aortic FMD because of its rarity.

108. Early results with the custom-made Fenestrated Anaconda aortic cuff in the treatment of complex abdominal aortic aneurysm. (Abstract)

Early results with the custom-made Fenestrated Anaconda aortic cuff in the treatment of complex abdominal aortic aneurysm. The objective of this study was to investigate the feasibility of a specific custom-made fenestrated aortic cuff in the treatment of complex abdominal aortic aneurysms (AAAs).Between 2013 and 2016, a total of 57 custom-made Fenestrated Anaconda (Vascutek, Inchinnan, Scotland, UK) aortic cuffs were placed in 38 centers worldwide. All centers were invited to participate (...) in 93%. The 30-day morbidity was 7 of 29 with a mortality rate of 4 of 29. Estimated glomerular filtration rate remained unchanged before and after surgery (76 to 77 mL/min/m2). Between preoperative and median follow-up of 11 months, estimated glomerular filtration rate was reduced statistically significantly (76 to 63 mL/min/m2). During follow-up, 9 cases had an increase in aneurysm sac diameter (5 cases >5 mm); 14 cases had a stable or decreased aneurysm sac diameter; and in 2 cases, no aneurysm

109. Chronic Nicotine Exposure Induces Murine Aortic Remodeling and Stiffness Segmentation—Implications for Abdominal Aortic Aneurysm Susceptibility Full Text available with Trip Pro

Chronic Nicotine Exposure Induces Murine Aortic Remodeling and Stiffness Segmentation—Implications for Abdominal Aortic Aneurysm Susceptibility Aim: Arterial stiffness is a significant risk factor for many cardiovascular diseases, including abdominal aortic aneurysms (AAA). Nicotine, the major active ingredient of e-cigarettes and tobacco smoke, induces acute vasomotor effects that may temporarily increase arterial stiffness. Here, we investigated the effects of long-term nicotine exposure (...) on structural aortic stiffness. Methods: Mice (C57BL/6) were infused with nicotine for 40 days (20 mg/kg/day). Arterial stiffness of the thoracic (TS) and abdominal (AS) aortic segments was analyzed using ultrasound (PWV, pulse wave velocity) and ex vivo pressure myograph measurements. For mechanistic studies, aortic matrix-metalloproteinase (MMP) expression and activity as well as medial elastin architecture were analyzed. Results: Global aortic stiffness increased with nicotine. In particular, local

111. Peripheral artery disease is associated with poor clinical outcome in patients with abdominal aortic aneurysm after endovascular aneurysm repair. (Abstract)

Peripheral artery disease is associated with poor clinical outcome in patients with abdominal aortic aneurysm after endovascular aneurysm repair. We investigated the effects of coronary artery disease (CAD) or peripheral artery disease (PAD) on clinical outcomes of patients with abdominal aortic aneurysm (AAA) treated with endovascular aortic aneurysm repair (EVAR).We retrospectively evaluated a total of 475 patients with AAA treated with EVAR at a single center. Patients were divided (...) characteristics were similar among the groups except for current smoking (A, 27.4%; B, 20.8%; C, 50.5%; p = 0.001). Three years after EVAR, the incidences of MACCE (A, 5.6%; B, 9.5%; C, 16.7%; p = 0.021) and stroke (A, 0%; B, 2.2%; C, 5.2%; p = 0.025) were highest in group C. All-cause death and aneurysm death did not differ among the groups. PAD [hazard ratio (HR) 2.88, 95% confidence interval (CI) 1.32-6.29, p = 0.008] and previous stroke (HR 4.39, 95% CI 1.94-9.93, p < 0.001) were independent predictors

115. Abdominal aortic aneurysm with periaortic malignant lymphoma differentiated from aneurysmal rupture by clinical presentation and magnetic resonance imaging Full Text available with Trip Pro

Abdominal aortic aneurysm with periaortic malignant lymphoma differentiated from aneurysmal rupture by clinical presentation and magnetic resonance imaging Abdominal aortic aneurysm (AAA) associated with periaortic malignant lymphoma is difficult to differentiate from aneurysmal rupture because of similarities in their clinical presentation and appearance on computed tomography images. We here report a case of AAA associated with periaortic malignant lymphoma diagnosed preoperatively (...) with an absence of typical symptoms, showing that AAA in periaortic malignant lymphoma can present without any clinical correlates. Magnetic resonance imaging was used to confirm the diagnosis. The patient was treated by endovascular repair, which may be safer and more effective than open surgery for AAA associated with malignant lymphoma because of the tight adhesion between the aneurysm and the lymphoid tissue.

Midterm results of endovascular aneurysm sealing to treat abdominal aortic aneurysm. Endovascular aneurysm sealing (EVAS) represents a novel approach to the treatment of abdominal aortic aneurysms. It uses polymer technology to achieve an anatomic seal within the sac of the aneurysm. This cohort study reports the early clinical outcomes, technical refinements, and learning curve during the initial EVAS experience at a single institution.Results from 150 consecutive EVAS cases for intact (...) , infrarenal abdominal aortic aneurysms are reported here. These cases were undertaken between March 2013 and July 2015. Preoperative, perioperative, and postoperative data were collected for each patient prospectively.The median age of the cohort was 76.6 years (interquartile range, 70.2-80.9 years), and 87.3% were male. Median aneurysm diameter was 62.0 mm (IQR, 58.0-69.0 mm). Adverse neck morphology was seen in 69 (46.0%) patients, including aneurysm neck length <10 mm (17.3%), neck diameter >32 mm

118. Retroperitoneal hematoma volume is a good predictor of perioperative mortality after endovascular aneurysm repair for ruptured abdominal aortic aneurysm. (Abstract)

Retroperitoneal hematoma volume is a good predictor of perioperative mortality after endovascular aneurysm repair for ruptured abdominal aortic aneurysm. The objective of this study was to validate the usefulness of retroperitoneal hematoma volume as a predictor of perioperative mortality after endovascular aneurysm repair (EVAR) for ruptured abdominal aortic aneurysm (rAAA).We retrospectively reviewed consecutive patients with rAAA who underwent the unified EVAR first protocol between 2012 (...) and 2016 at any one of three participating institutions in Japan and were prospectively registered in a dedicated database. Only patients with preoperative computed tomography scans adequate for three-dimensional volumetric analysis were included. Volumetry was used to measure the retroperitoneal hematoma volume. To adjust for body size differences between patients, the retroperitoneal hematoma volume was divided by the abdominal cavity volume, and the predictive power of this ratio was validated using

Endovascular aneurysm sealing with chimney grafts to treat juxtarenal and suprarenal abdominal aortic aneurysms: Early results from 62 cases. The treatment of juxtarenal abdominal aortic aneurysms is challenging. Open surgical repair is not a viable option for many patients. The use of endovascular aneurysm sealing (EVAS) with chimney grafts (Ch-EVAS) has been proposed as an immediately available, off-the-shelf option for individuals with juxtarenal aneurysms who require urgent treatment (...) or are unsuitable for fenestrated or branched devices. This study reports the outcomes from our first patients to undergo this procedure.Data were collected prospectively for 62 consecutive patients undergoing Ch-EVAS at our institution. The procedures were undertaken for intact juxtarenal or suprarenal aneurysms in patients who were unfit for open repair or needed urgent treatment or when the aneurysm morphology was unsuitable for treatment with fenestrated or branched endografts.Between July 2013 and June

120. Totally percutaneous versus surgical cut-down femoral artery access for elective bifurcated abdominal endovascular aneurysm repair. Full Text available with Trip Pro

Totally percutaneous versus surgical cut-down femoral artery access for elective bifurcated abdominal endovascular aneurysm repair. Abdominal aortic aneurysms (AAAs) are a vascular condition with significant risk attached, particularly if they rupture. It is, therefore, critical to identify and repair these as an elective procedure before they rupture and require emergency surgery. Repair has traditionally been an open surgical technique that required a large incision across the abdomen (...) . Endovascular abdominal aortic aneurysm repairs (EVARs) are now a common alternative. In this procedure, the common femoral artery is exposed via a cut-down approach and a graft introduced to the aneurysm in this way. This review examines a totally percutaneous approach to EVAR. This technique gives a minimally invasive approach to femoral artery access that may reduce groin wound complication rates and improve recovery time. The technique may, however, be less applicable in people with, for example, groin
