In Situ Needle Fenestration during Thoracic Endovascular Aneurysm Repair: Successful Fenestration of Two Overlapping Thoracic Stent Grafts.

Endovascular stent grafting is becoming more common in treating complex thoracic aortic aneurysms and dissections. When it becomes necessary to cover the supra-aortic vessels, maintaining blood supply through the supra-aortic branches can be achieved by performing in situ needle fenestration. We present a case of a 65-year-old man with a type B aortic dissection that extended from the origin of the left subclavian artery.

Bilateral hypoplasia of the internal carotid artery and ectasia of the internal jugular vein.

Hypoplasia of the internal carotid artery and internal jugular vein ectasia are rare congenital abnormalities, whose diagnosis and treatment are not uniformly described. A 32-year-old neurologically asymptomatic woman with renal failure had a carotid artery duplex ultrasound scan as part of an evaluation for renal transplantation and was found to have bilateral internal carotid artery hypoplasia. Computed tomography angiography confirmed congenital bilateral internal carotid artery stenosis and left internal jugular vein ectasia.

Aortic Rupture during Endovascular Aneurysm Repair. Report of Our Experience and Review of the Literature.

Background:  Aortic neck wall rupture during endovascular repair of abdominal aortic aneurysms (EVAR) is an underreported potentially fatal complication. Only a few cases have been reported. The main cause of this complication is repeated attempts at balloon inflation or overdilation to treat an intraoperative Type 1a endoleak.

The use of iliac branch devices for preservation of flow in internal iliac artery during endovascular aortic aneurysm repair.

Objective: Common iliac artery aneurysms are present in more than a third of patients with abdominal aortic aneurysm and may pose a challenge during open and endovascular repair. Although embolization of the internal iliac artery is an established method, it may be complicated with buttock claudication, erectile dysfunction, colon ischemia, and pelvic necrosis. Iliac branch devices (IBDs), which permit preservation of the hypogastric artery, have been used to prevent these complications.

Extracranial Internal Carotid Artery Aneurysm in a Patient with Marfan Syndrome.

Extracranial internal carotid artery (ICA) aneurysms are rare and most of them are considered of atherosclerotic etiology. Marfan syndrome (MS) is a systemic connective tissue disorder caused by mutation in the extracellular matrix protein fibrillin 1. Clinical manifestations of the MS include aortic aneurysms, dislocation of the ocular lens, and long bone overgrowth.

Current concepts for the evaluation and management of diabetic foot ulcers.

The lifetime risk for diabetic patients to develop a diabetic foot ulcer (DFU) is 25%. In these patients, the risk of amputation is increased and the outcome deteriorates.More than 50% of non-traumatic lower-extremity amputations are related to DFU infections and 85% of all lower-extremity amputations in patients with diabetes are preceded by an ulcer; up to 70% of diabetic patients with a DFU-related amputation die within five years of their amputation.

Vascular Injury in Orthopedic Trauma.

Vascular injury in orthopedic trauma is challenging. The risk to life and limb can be high, and clinical signs initially can be subtle. Recognition and management should be a critical skill for every orthopedic surgeon.

Arterial Stiffness Alterations and Inflammatory Response Following Endovascular Aortic Repair: Based on a Presentation at the 2013 VEITH Symposium, November 19-23, 2013 (New York, NY, USA).

Endovascular abdominal aortic aneurysm repair (EVAR) and thoracic aortic aneurysm repair (TEVAR) have been widely incorporated into clinical practice. However, changes in arterial stiffness and post-implantation syndrome after aortic endografting remain important issues under investigation. The aneurysm sac wall motion after successful EVAR and TEVAR reflects complex interactions between all the components of the excluded aneurysm, including true compliance of the aneurysm wall itself, intra-aneurysm sac pressure, remodeling of the thrombus, and mechanical characteristics of the endograft.
