PURPOSE We aimed to present our clinical experience with the renal artery catheterization (RAC) technique, which reduces the volume of intra-arterial contrast media (ICM) used during endovascular aortic repair (EVAR), and describe the short-term results of this technique. MATERIALS AND METHODS We retrospectively evaluated 16 patients (15 males and one female) who underwent EVAR between March 2011 and February 2012 using the RAC technique for an abdominal aortic aneurysm. A Simmons-1 catheter was preferred for renal artery cannulation. The mean age of the patients at the time of treatment was 70 years (range, 61-82 years). Fifteen cases were fusiform aneurysms, and one case was a saccular aneurysm. Creatinine and estimated glomerular filtration rate (eGFR) values were recorded before the procedure and during the first 72 hours postprocedure. RESULTS Bifurcated stent grafts were implanted with 100% procedural success using the RAC technique. The inferiorly positioned renal artery was cannulated with a Simmons-1 catheter in the first five patients, and was maintained at the level of the renal artery orifice in the remaining patients. The mean volume of the ICM used was 47 mL (range, 23-83 mL). The creatinine and eGFR values were not significantly different between the pre- and postoperative periods (P > 0.05). CONCLUSION Reducing the volume of ICM used during EVAR is critical for protecting renal function. The RAC technique is a safe and effective method in appropriate patients when performed by experienced clinicians.

This study was undertaken to compare early postoperative results, programmed multi-detector row computed tomography coronary angiographic patency and midterm results of revascularization by sequential radial artery grafting with those of single radial artery grafting during a five-year period. Patients were grouped as those with sequential radial artery grafts (Group A, n = 27) and single radial artery grafts (Group B, n = 26). Multi-detector row computed tomography coronary angiography was scheduled at 1 and 5 years postoperatively. Each distal anastomosis was accepted as nonfunctional if a radial artery graft was occluded proximally or there was a critical stenosis. One sequential radial artery graft and two single radial artery grafts failed in the 1-year period (p>0.05). In the 5-year period, three radial artery grafts failed in each group (p>0.05). In Group A, there was no mortality in the five-year period, but in Group B, one patient died four years after the operation due to cardiac problems (p>0.05). In addition to one death in Group B, there were three percutaneous interventions and two myocardial infarctions among the 26 patients during the five-year follow-up. In group A, among 27 patients, there were 4 percutaneous interventions and one myocardial infarction (p>0.05). Although the sample size is relatively small to be conclusive, these data suggest that sequential radial artery grafting may be considered as a method of choice for maximizing arterial graft survival and patency. Noninvasive control of sequential and single radial artery grafts with multi-detector row computed tomography is feasible with no discomfort for the patient and excellent visualization of grafts.

Papillary fibroelastomas (PFEs) are primary cardiac tumors with a benign and avascular nature. Majority of the PFEs are originated from the valvular endocardium, while the most common site is aortic valve. In this case, we present a patient with multiple PFEs originating from the right ventricular outflow tract who was admitted to our clinic with exertional dyspnea. As far as we know, this is the first case of this unusual presentation of multiple PFEs and also had a history of breast cancer and permanent pacemaker reported in the literature.

PURPOSE Acute thoracic aortic syndrome (ATAS) is a novel term to define emergency aortic conditions with common clinical features and challenges. Traditional management of ATAS includes surgical replacement of the aorta and is correlated with high perioperative mortality and morbidity. We aimed to evaluate our experience and outcomes in patients presenting with ATAS, managed by endovascular techniques. METHODS This cohort consisted of 31 consecutive patients (24 males; mean age, 57.5±13.81 years; range, 19-84 years) with acute thoracic aortic pathologies who underwent endovascular repair between January 2011 and January 2015. The study was designed as a retrospective analysis of prospectively maintained data. RESULTS Complicated acute type-B aortic dissection was the most common pathology (35.5%). All aortic stent-grafts (n=37) and dissection stents (n=9) were implanted with 100% procedural success. The overall in-hospital mortality was 9.7%. The mean follow-up duration of patients who were alive at 30 days was 25.9±11.49 months (3-53 months). So far, there have been no late deaths after 30 days. CONCLUSION In the high-risk setting of ATAS, endovascular procedures come forward as novel therapeutic strategies with promising results. Endovascular repair of ATAS can be considered as a first-line treatment alternative under emergency conditions with encouraging results, particularly when conventional surgical repair cannot be implemented due to prohibitive comorbidities.

Coarctation of aorta and sinus of Valsalva aneurysm are frequently missed congenital cardiac defects that their diagnosis might be delayed. To our knowledge, coincidence of these cardiac defects is unusual and has not been reported in the literature before. Here, we present a patient with coarctation of aorta and ruptured noncoronary sinus of Valsalva aneurysm leading to aorto-right atrial fistula in the early postpartum period and our management of this unusual case.
