OBJECTIVE: Reinterventions after fenestrated or branched endovascular aneurysm repair (F/B-EVAR) are sometimes necessary to maintain aneurysm exclusion or endograft and target artery patency. These reinterventions are nontrivial, potentially associated with morbidity, mortality, and resource utilization. Whereas rates, types, and outcomes of reintervention after infrarenal EVAR have been well described, they have not been well described for F/B-EVAR. We sought to characterize the morbidity, mortality, and resource utilization due to reinterventions after F/B-EVAR...

Endovascular aneurysm repair has become the first-line treatment modality for infrarenal aortic aneurysms. However, obtaining successful long-term results frequently require re-interventions. Particularly, delayed type 1a endoleaks pose a challenging problem, as they are often associated with proximal extension of the aneurysmal process to juxta or para-renal aortic segments. We describe two remedial techniques to repair delayed type 1a endoleak by extending the seal zone to the suprarenal aorta, while incorporating the renal arteries...

Abdominal aortic pseudoaneurysm is a rare but life-threatening condition that occurs due to penetrating or blunt trauma. Clinical manifestations are variable, and the time interval from the initial trauma to diagnosis is variable. A prompt diagnosis and an aggressive management approach are required to avoid catastrophic complications. Possible treatment options are open surgical repair, endovascular repair, pseudoanerysmal sac thrombosis induction through direct thrombin injection, and coil embolization. Here, we present the case of a 75-year-old man affected by an infrarenal abdominal aortic pseudoaneurysm presenting with abdominal and lumbar pain for 3 days, who was successfully treated with an endograft...

Mycotic aortic aneurysms are exceedingly uncommon in infants and they have a high risk of rupture. Their surgical management is extremely challenging. We report a case of a 22-month-old girl who presented with abdominal pain and fever revealing a ruptured mycotic aneurysm of the infrarenal aorta. The surgical treatment consisted of a ligature of the proximal and distal ends of the aneurysm. Postoperative course was significant for hypertension. A year and a half follow-up showed no other complications. Limited data are available concerning our chosen technique, but the reported cases showed a good short-term outcome...

We report an aneurysm degeneration of a vein graft in a previous aortorenal bypass performed five years earlier for severe right renal artery stenosis due to Takayasu arteritis. The patient was a 31-year-old woman who suffered from refractory hypertension. The autogenous bypass adopting great saphenous vein was performed from her infrarenal abdominal aorta to her right renal artery. Five years after the operation, the patient complained vague discomfort in her abdomen. Three-dimensional computed tomography angiography reconstruction demonstrated the existence of an aneurysm with a maximum diameter of 1...

BACKGROUND: This study aimed to review our clinical results and determine how preoperative patent lumbar arteries (LAs) influence the occurrence of type II endoleaks or aneurysm sac enlargement after endovascular aneurysm repair (EVAR), and to identify the preoperative computed tomography findings of persistent type II endoleaks from patent LAs that indicate the need for preventive procedures during EVAR. METHODS: A total of 293 patients who underwent EVAR for infrarenal abdominal aortic aneurysm between August 2007 and July 2013 were reviewed...

Inferior vena cava (IVC) filters have been used for over five decades as an alternative to anticoagulation therapy in the treatment of venous thromboembolic disease. However, complications associated with IVC filters remain common. Though many studies have investigated blood flow in the IVC, the effects of respiration-induced IVC collapse have not been evaluated. Our hypothesis is that IVC collapse may have an influence on IVC filter performance. Therefore, we herein investigate the hemodynamics in uncollapsed and collapsed IVC configurations using in vitro flow experiments and computational simulations...

Background  To report a case of a high-risk patient treated with hypogastric chimney and aortic endograft for a native infrarenal aorta aneurysmal degeneration, 20 years after an aortobifemoral bypass procedure for severe iliac occlusive disease. Methods  A two-stage procedure was planned. The first stage was right internal iliac artery (IIA) embolization and simple angioplasty of left IIA. The second stage consisted of aortouniiliac endograft with femoral crossover and left IIA chimney. Results  Femoral crossover complicated with early thrombosis, but a decision on conservative medical treatment with anticoagulation was made based on no rest pain or severe claudication...

Atrial myxoma is the most common benign tumor of the heart; moreover, atrial myxoma embolization to the peripheral vessels is rare. We present an unusual case of total acute infrarenal aortic occlusion resulting from embolic implantation from a left ventricular myxoma. A 37-year-old man with acute lower limbs ischemia, spinal cord ischemia, and acute renal insufficiency was urgently operated and discharged after surgery.

Background/aim: The protective effect of erdosteine on local and distant organ injury due to ischemia/reperfusion has been well documented but its effect on erythrocyte deformability needs further investigation. Our aim was to investigate the effect of erdosteine on erythrocyte deformability in the infrarenal aorta of rats undergoing ischemia/reperfusion. Materials and methods: Our study was conducted with 18 Wistar albino rats. Rats were divided into 3 groups: a randomized control group (group 'control', n = 6), an ischemia/reperfusion group without erdosteine (group 'ischemia/reperfusion', n = 6), and an ischemia/reperfusion group with erdosteine at 150 mg kg−1, intraperitoneally (group 'ischemia/reperfusion - erdosteine', n = 6)...

We report the case of a 75 years old man submitted to traditional EVAR for infrarenal abdominal aortic aneurysm. He presented a late type II endoleak 6 months after operation, initially without sac enlargement. One year later, a CT scan control demonstred a sac expansion > 10 mm, also responsible of a secondary proximal type I endoleak. The patient was submitted to transarterial embolization of lumbar arteries through left internal iliac artery, followed by type I endoleak correction with a proximal cuff deployment...

Introduction Formation and renewal of intramural thrombus is associated with inflammation, and contributes to the complexity of aneurysm repair. Current cardiovascular pharmacotherapy includes several inflammatory modulators such as aspirin, statins, clopidogrel, and angiotensin-converting enzyme inhibitors. The purpose of our study was to investigate the effect of these inflammatory modulators on radiographically-determined thrombus sac volume. Methods Pre-operative computed tomography scans were reviewed in patients who underwent elective infrarenal aortic aneurysm repair...
