INTRODUCTION: The usefulness of carbon dioxide (CO2 ) gas digital subtraction angiography (DSA) has been reported for patients with renal insufficiency and allergy to iodinated contrast agents. However, CO2 gas cannot replace the iodinated contrast agent in all cases owing to some disadvantages. We describe balloon-occluded CO2 DSA (B-CO2 DSA) as an improved CO2 DSA procedure for interventions in the internal iliac artery (IIA) region and compare the quality of images obtained using conventional CO2 DSA and B-CO2 DSA...

Objective: To evaluate the early results of fenestrated endovascular aortic repair (FEVAR) using physician-modified stent grafts (PMSGs) for the treatment of patients with thoracoabdominal pathologies. Methods: Nineteen consecutive patients who underwent FEVAR using PMSGs between April 2012 and September 2017 were retrospectively reviewed. The modality of FEVAR technique was assessed, perioperative clinical data was recorded and the early results were evaluated. Results: Indications were thoracoabdominal aortic pathologies, including juxtarenal abdominal aortic aneurysm (JAAA) ( n =12), chronic thoracoabdominal aortic dissection with aneurysmal dilatation ( n =3), thoracoabdominal aortic aneurysm (TAAA) ( n =1), infrarenal AAA with an accessory renal artery in the segment of the aneurysmal neck ( n =2) and type Ⅰ endoleak after EVAR for AAA( n =1)...

BACKGROUND: Cerebrospinal-fluid (CSF) drainage is recommended by current guidelines for spinal protection during open and endovascular repairs of thoracic and thoraco-abdominal aortic aneurysms. In the published literature, great variability exists in the rate of CSF-related complications and morbidity. Herein, we perform a systematic review and meta-analysis on the incidence of CSF drainage-related complications, and compare the complication rates between open and endovascular repairs...

OBJECTIVE: Very few reports have previously described spondylodiscitis as a potential complication of endovascular aortic aneurysm repair (EVAR). We present to our knowledge the first case series of spondylodiscitis following EVAR based on our institution's experience over an 11-year period. Particular attention is paid to the key imaging features and challenges encountered when performing spinal imaging in this complex patient group. MATERIALS AND METHODS: Of 1,847 patients who underwent EVAR at our institution between January 2006 and January 2017, a total of 9 patients were identified with imaging features of spondylodiscitis (0...

Computerized Tomography Angiography (CTA) based follow-up of Abdominal Aortic Aneurysms (AAA) treated with Endovascular Aneurysm Repair (EVAR) is essential to evaluate the progress of the patient and detect complications. In this context, accurate quantification of post-operative thrombus volume is required. However, a proper evaluation is hindered by the lack of automatic, robust and reproducible thrombus segmentation algorithms. We propose a new fully automatic approach based on Deep Convolutional Neural Networks (DCNN) for robust and reproducible thrombus region of interest detection and subsequent fine thrombus segmentation...

OBJECTIVE: Dementia represents a major risk factor for medical complications and has been linked to higher rates of complication after surgery. Given the systemic nature of vascular disease, medical comorbidities significantly increase cost and complications after vascular surgery. We hypothesize that the presence of dementia is an independent predictor of increased postoperative complications and higher health care costs after vascular surgery. METHODS: The Vascular Quality Initiative database was queried for all patients undergoing vascular surgery at a single academic medical center from 2012 to 2017...

OBJECTIVE: Percutaneous endovascular aneurysm repair (EVAR) can be performed with general anesthesia (GA) or local anesthesia (LA). Our goal was to assess perioperative outcomes comparing anesthesia type in percutaneous EVAR. METHODS: The Vascular Quality Initiative database was queried for all exclusively percutaneous EVAR procedures. Univariable analysis was used to compare which patients were offered LA. Multivariable analysis was used to determine the independent effect of anesthesia type...

PURPOSE OF REVIEW: The effects of statin loading before, during or after vascular interventions on cardiovascular and renal outcomes are discussed. Furthermore, the selection of optimal statin type and dose, according to current evidence or guidelines, is considered. The importance of treating statin intolerance and avoiding statin discontinuation is also discussed. RECENT FINDINGS: Statin loading has been shown to beneficially affect cardiovascular outcomes, total mortality and/or contrast-induced acute kidney injury, in patients undergoing vascular procedures such as percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG), carotid endarterectomy (CEA), carotid artery stenting, endovascular aneurysm repair, open abdominal aortic aneurysms (AAA) repair and lower extremities vascular interventions...

Endovascular repair of abdominal aortic aneurysms have been performed successfully since 1991. However, 20% to 50% of these patients may develop an endoleak or continued aneurysmal sac expansion or perfusion despite stent graft coverage. Current recommendations suggest lifelong surveillance with computed tomographic angiography (CTA) at least 1 month after intervention and yearly after that. In select patients with a stable aneurysm sac on computed tomography performed 1 year after treatment, future screening could be performed with ultrasonography...

BACKGROUND: Although preoperative and perioperative statin therapy improves postoperative outcomes in several populations, few data examine its association with survival after abdominal aortic aneurysm (AAA) repair. In addition, no data exist regarding the benefits of starting statins in patients with AAA not currently taking them. METHODS: We performed a registry-based study of all patients undergoing repair of AAAs in the Vascular Quality Initiative between 2003 and 2017 without documented statin intolerance...

BACKGROUND: Lifelong postoperative surveillance is recommended following endovascular aneurysm repair (EVAR). Although the purpose is to prevent and/or identify complications early, it also results in increased cost and workload. This study was designed to examine whether it may be possible to identify patients at low risk of complications based on their first postoperative CT angiogram (CTA). METHODS: All patients undergoing EVAR in two Swedish centres between 2001 and 2012 were identified retrospectively and categorized based on the first postoperative CTA as at low risk (proximal and distal sealing zone at least 10 mm and no endoleak) or high risk (sealing zone less than 10 mm and/or presence of any endoleak) of complications...
