The authors analyzed the single-center experience of treatment of 72 patients with abdominal aortic aneurisms and severe accompanied pathology. The aneurisms were repaired by stentgrafts. All the patients had abdominal aortic aneurisms with the diameters from 41 to 84 mm against the background of severe somatic pathology. It was a contraindication to planned open surgery. An installation of stent-graft was successful in all 72 follow-ups. It wasn’t necessary to use a conversion to open surgery. The follow-up period consisted of 44,6±2,1 months. Control ultrasound and computer tomography studies hadn’t revealed an increase of aneurism sack sizes or «leakages». A reduction of abdominal aortic aneurism sizes was noted in 37 patients on 4-5% during first year after operation. The stentgraft implantation extends the possibilities of abdominal aortic aneurism treatment for patients from a high surgical risk group.

Objectives We represent two cases of late proximal type I endoleak following EVAR with aneurysm expansion that were treated with a custom-made graft with inner branches. Methods Two patients of 87 and 82 years old were operated by EVAR 6 and 8 years ago for abdominal aortic aneurysm. Both had proximal type I endoleak with aneurysm sac expansion. Open surgery had a high risk, and a proximal aortic extension with a simple aortic cuff was not possible neither because previous EVAR grafts were already at the level of the renal arteries. A custom-made endograft with inner branches was planned as a fenestrated graft was not technically possible. Results We successfully treated both patients using a custom-made graft with four inner branches from Jotec (Cryolife, Kennesaw, GA). Three months’ follow-up CT scan did not show any endoleaks. All target vessels were patent with good conformability of the bridging stents. Conclusion The treatment of proximal type I endoleak using inner branches’ endografts is feasible. This novel technology might broaden the indications for complex aortic repair in a group of patients where fenestrated endografts are not possible.

In this single center, retrospective cohort study we wished to compare early and total mortality for all patients treated for abdominal aortic aneurysms (AAA) with open surgery who were taking statins compared to those who were not. A cohort of 640 patients with AAA was treated with open surgery between 1999 and 2012. Patients were consecutively recruited from a source population of 390,000; 21.3% were female, and the median age was 73 years. The median follow-up was 3.93 years, with an interquartile range of 1.79–6.58 years. The total follow-up was 2855 patient-years. An explanatory strategy was used. The propensity score (PS) was implemented to control for selection bias and confounders. The crude effect of statin use showed a 78% reduction of the 30-day mortality. A stratified analysis using the Mantel–Haenszel method on quintiles of the PS gave an adjusted effect of the odds ratio equal to 0.43 (95% CI: 0.18–0.96), indicating a 57% reduction of the 30-day mortality for statin users. The adjusted rate ratio was 0.62 (95% CI: 0.45–0.83), indicating a reduction of long-term mortality of 38% for statin users compared to non-users for a median follow-up of 3.93 years. This retrospective cohort study showed a significant beneficial effect of statin use on early and long-term survival for patients treated with open surgery. To be conclusive, our results need to be replicated by a randomized clinical trial.

Introduction. Imaging is essential in the assessment of endovascular infrarenal abdominal aortic repair results. Complications include endoleaks, graft migration, kinking and infolding, stenosis, occlusion, and secondary ruptures. Examination Modalities. Contemporary imaging strategies are based on using noninvasive imaging modalities. After endovascular infrarenal abdominal aortic repair, the standard evaluation modality is computed tomography angiography, whereas additional modalities include magnetic resonance imaging, ultrasonography, and radiography. However, although an invasive imaging method, digital subtraction angiography is still performed in some patients. Computed tomography angiography provides excellent contrast, spatial resolution, and exact measurements of structures of interest, which is essential in the follow-up. Follow-up Protocol. Currently recommended follow-up protocol in the first year is contrast- enhanced computed tomography imaging at 1 and 12 months after the procedure. Conclusion. Due to its characteristics, reproducibility and availability, computed tomography angiography remains the cornerstone diagnostic modality of post-procedural assessment in patients with endovascular infrarenal abdominal aortic repair.

A six-year-old, male Yorkshire terrier was presented with acute vomiting, anorexia, depression, watery diarrhea and sudden blindness. On the basis of a transabdominal ultrasonographic examination, the presence of a prominent aortic aneurysm was established. The aneurysm of the aorta was confirmed at post-mortem examination. Unexpectedly, a pheochromocytoma of the left adrenal gland was found to be involved with the aneurysm. In this case report, the unusual occurrence of a large, unruptured abdominal aortic aneurism (AAA) concurrent with a pheochromocytoma in a male Yorkshire terrier dog is discussed.

Purpose: The purpose of this study was to investigate the change in the diameter of infrarenal abdominal aortic aneurysm (AAA) sacs after endovascular aortic repair (EVAR) in Taiwanese patients and to depict its association with clinical outcomes. Materials and Methods: This retrospective cohort study was conducted on patients who underwent EVAR for infrarenal AAA between January 2011 and December 2016. All preoperative and follow-up computed tomography (CT) images were reviewed. Postoperative CT angiography was arranged after 1 month and annually thereafter. The maximal diameter on the axial plane and the maximal diameter perpendicular to the centerline on the coronal and sagittal planes were measured. The study examined post-EVAR sac diameter change over time and compared the differences in adverse events (AEs) among groups. Results: The survey included a total of 191 patients with a median follow-up duration of 2.5 (interquartile range: 1.1–2.9) years. Overall survival rates at 1, 2, and 5 years were 92%, 81%, and 76%, respectively. According to their last CT scans, the patients were categorized into 3 groups as follows: shrinkage, stationary, and enlargement, which comprised 58 (30.4%), 118 (61.8%), and 15 (7.9%) patients, respectively. Pre-EVAR characteristics and sac diameters were similar among the groups. Sac shrinkage was exclusively observed in the first 2 years, whereas sac enlargement developed at all follow-up periods. Patients with sac enlargement had higher incidence rates of endoleaks, complications, and reintervention than the other groups. Conclusion: Based on our observations, post-EVAR sac shrinkage only occurs in the first 2 years; however, post-EVAR sacs may enlarge at any point and even after 5 years. In our study, patients with sac enlargement had higher rates of adverse events and reintervention.
