Stenting of innominate vein compression syndrome.

We report the case of a 60-year-old woman who sought medical attention for left cervical and supraclavicular pain and swelling. Previous computed tomography, intravascular ultrasound, and venography studies were reviewed, confirming extrinsic compression of the left innominate vein by the left common carotid artery against the left clavicle head. Stenting of the lesion was performed, with good mid-term symptom relief and patency.

[Endovascular management of chronic limb ischemia. Experience in 48 procedures].

Background: Chronic limb ischemia can lead to high rates of limb loss and mortality. Open surgery is the gold standard for treatment of distal disease. Endovascular surgery should have less complications with similar outcomes.

Endovascular Management of a Ruptured Iliac Aneurysm With an Inferior Vena Cava Fistula.

Aortocaval fistula is uncommon and often associated with a ruptured iliac or abdominal aortic aneurysm. It has a high mortality secondary to the aneurysmal rupture but also to a high output heart failure. Open surgery has been the standard; however, endovascular management has emerged with lower mortality.

Endovascular Repair of Bilateral Internal Mammary Artery Aneurysms in a Patient with Marfan Syndrome.

Background: True internal mammary artery aneurysms are rare but rupture has been described.

Case Report: A 39-year-old male patient with Marfan syndrome was diagnosed with large asymptomatic bilateral internal mammary artery aneurysms (IMAAs) on contrast-enhanced CT scan, without other arterial lesions. Both aneurysms were coil embolized, a stent graft was deployed in the left subclavian artery to cover a wide neck that precluded complete and safe embolization of the left IMAA.

Juxtarenal Abdominal Aortic Aneurysm: Results of Open Surgery in an Academic Center.

Background: The objective of the study is to report our experience with conventional surgery for juxtarenal abdominal aortic aneurysms (JRAs) by evaluating incidence of acute renal failure and perioperative mortality. Secondary objectives are to evaluate general morbidity and the need for permanent postoperative dialysis and to assess the influence on long-term survival of preoperative risk factors and deterioration of perioperative renal function.

Methods: A retrospective cohort study of 110 patients with JRA electively treated by open surgery between March 1992 and March 2018 was made.

Antegrade hypogastric revascularization during endovascular aortoiliac aneurysm repair: an alternative to bilateral embolization.

Anatomy has been the major challenge to overcome to increase safe and durable applicability of endografting for the treatment of abdominal aortic aneurysm. Bilateral iliac aneurysm preventing an appropriate distal landing zone for the endograft is a common condition and can be managed by (a) increasing the diameter of the endograft, with limitations in available sizes, (b) bilateral hypogastric embolization, accepting an increased morbidity, (c) the use of a branched device, increasing the cost and currently with limited availability, (d) combined surgical hypogastric revascularization by the retroperitoneal approach, or (e) retrograde revascularization from the ipsilateral external iliac artery using an endograft. We describe the use of widely available devices to obtain stable antegrade revascularization of one hypogastric artery during aortic endografting.

Cigarette smoking increases aortic dilatation without affecting matrix metalloproteinase-9 and -12 expression in a modified mouse model of aneurysm formation.

Objective: The development of abdominal aortic aneurysms (AAA) is presumed to result from multiple genetic and environmental factors, with exposure to tobacco smoke the single largest known factor predisposing to aneurysm growth. We have attempted to adapt the elastase-perfused animal model to determine whether tobacco exposure can lower the threshold of aortic injury necessary for AAA development.

Methods: Adult C57BL/6 mice underwent transient perfusion of the infrarenal aorta with an active solution of elastase: high-dose (HDE, 0.

Pharmacological targets in the treatment of abdominal aortic aneurysms.

The natural history of an abdominal aortic aneurysm (AAA) is of progressive aortic wall degeneration occurring over the course of many years, ultimately, culminating in loss of structural integrity and fatal aortic rupture. Although surgical exclusion of an aneurysm can effectively prevent aortic rupture in large aneurysms, small aneurysms are generally completely asymptomatic and are very unlikely to rupture. Further, AAA can be easily diagnosed with noninvasive testing; thus, small aneurysms present an excellent opportunity for disease-modifying pharmacological intervention.
