“…Currently, the classification most recommended by the vascular surgeon's societies is the one developed by White et al, that was modified in recent years, dividing endoleaks into five types (19)(20)(21) . This classification is based on the origin of the blood flow into the aneurysmal sac and has direct implication on the treatment required for each case.…”

“…For this reason, multiphase CT angiography has been recommended: a typical protocol includes images before the administration of contrast medium, images after the administration of contrast in the arterial phase and images in the delayed phase. Pre-contrast images can be useful in the differentiation of calcifications in the endoleak aneurysmal sac, thus reducing the number of inconclusive studies (20,28) .…”

“…Color Doppler US is well accepted in the follow-up of abdominal aortic aneurysms but, in spite of being noninvasive, widely available, inexpensive, easy to perform and non-ionizing method, its accuracy and reliability in the evaluation of aneurysms after endovascular repair is not well defined. Additionally, initial studies have demonstrated a limited success of this method (20,30) .…”

OBJECTIVE: To describe a series of endoleak cases and their respective classification. MATERIALS AND METHODS: The authors developed a retrospective study of endoleaks diagnosed at their institution in the period between 2005 and 2009. Twenty cases were included to illustrate the different types of endoleaks. RESULTS: Seventy percent of the patients were men, and the ages ranged from 43 to 91 years (mean, 76.3 years). Thirteen cases were observed in the infrarenal abdominal aorta, four in the thoracic aorta, two in the iliac artery, and one in the carotid territory. Ultrasonography was the method utilized for diagnosis in three cases, and computed tomography in the other 17 cases. 5.

“…The control examination after intervention should include an unenhanced acquisition and two contrast-enhanced CT data sets (arterial and delayed phase). Some authors recommend delayed phase imaging because endoleaks show variable flow rates and are, therefore, not necessarily detected during the early contrast-enhanced phase [16,20].…”

Hybrid-repair of thoraco-abdominal or juxtarenal aortic aneurysm: what the radiologist should know

et al. 2009

Purpose: Endovascular aneurysm repair of the infrarenal or thoracic aorta has been shown to be a less invasive alternative to open surgery. A combined aneurysm of the thoracic and abdominal aorta is complex and challenging; the involvement of renal and/or visceral branches requires new treatment methods. Methods: A hybrid approach is currently an accepted alternative to conventional surgery. Renal and/or visceral revascularisation enables subsequent stent-graft placement into the visceral portion of the aorta. Results: Knowledge of the surgical procedure and a precise assessment of the vascular morphology are crucial for pre-procedural planning and for detection of post-procedural complications. Multi-detector computed tomography angiography (MDCTA) combined with two-and threedimensional (2D and 3D) rendering is useful for pre-interventional planning and for the detection of postprocedural complications. Threedimensional rendering allows proper anatomical analyses, influencing interventional strategies and resulting in a better outcome. Conclusions: With the knowledge of procedurespecific MDCTA findings in various vascular conditions, the radiologist and surgeon are able to perform an efficient pre-interventional planning and follow-up examination. Based on our experience with this novel technique of combined open and endovascular aortic aneurysm treatment, this pictorial review illustrates procedure-specific imaging findings, including common and rare complications, with respect to 2D and 3D post-processing techniques.

“…3 Currently, the gold standard follow-up modality after EVAR is computed tomography angiography (CTA). 4 The benefits of CTA over duplex ultrasound scanning (DUS) are that it is highly reproducible, less influenced by body habitus, and offers faster image acquisition. There are however important limitations, including repeated radiation exposure, contrast-related complications (eg, allergy and renal nephropathy), and the high cost of serial examination.…”

Duplex Ultrasound Scanning (DUS) Versus Computed Tomography Angiography (CTA) in the Follow-Up After EVAR

et al. 2009

Introduction: Computed tomography angiography (CTA) is the gold standard follow-up modality after endovascular aneurysm repair (EVAR). A potential alternative noninvasive and less expensive modality is duplex ultrasound scanning (DUS). Methods: We studied 314 follow-up paired scans (DUS and CTA) in 59 patients with EVAR. Results: Endoleak-Endoleak was detected in 23.7% patients. The sensitivity and specificity rates of DUS were 54% and 95.3%, respectively. All 9 endoleaks that needed secondary intervention were detected on DUS. Eight of those were identified within a year after EVAR. Sac size-The mean difference in maximum diameter between the DUS and CTA was 5 mm in 84.5% of cases and 10 mm in 97.1%. Graft patency-There was 100% agreement between CTA and DUS. Conclusions: Duplex ultrasound scanning was reliable as it detected all the leaks that needed reintervention after EVAR. Duplex ultrasound scanning showed similar results to CTA in detecting sac size and patency.
