Iatrogenic brachial plexus injuries secondary to expanding hematomas and pseudoaneurysms have been described in limited nature in previously published data. We present the case of a 55-year-old woman who developed neurologic deficits because of a compressive hematoma after axillary arteriography. She underwent emergent exploration of her left arm with decompression ...

In recent years, catheter-based aortic valve interventions have become established procedures for the treatment of high-risk and advanced age patients with aortic valve pathologies. One of the limitations of the widespread applicability of this procedure is the annulus size. Until recently, no prosthesis was available to treat patients with a ...

BACKGROUND: The ankle-brachial index (ABI) is a simple, noninvasive, widely used test that detects peripheral arterial disease (PAD). In patients with diabetes, the ABI is notoriously unreliable and this is usually attributed to medial calcinosis, which stiffens the arteries and renders them poorly compressible. However, the distribution of atherosclerotic lesions ...

Carotid endarterectomy (CEA) is currently accepted as the gold standard for interventional revascularisation of diseased arteries belonging to the carotid bifurcation. Despite the proven efficacy of CEA, great interest has been generated in carotid angioplasty and stenting (CAS) as an alternative to open surgical therapy. CAS is less invasive compared ...

In CKD, large arteries remodel and become increasingly stiff. The greater pulsatile pressure reaching the glomerulus as a result of increased aortic stiffness could induce renal damage, suggesting that the stiffening and remodeling of large arteries could affect the progression of CKD. We measured carotid-femoral pulse wave velocity, aortic pressure ...

The majority of infrarenal abdominal aortic aneurysm (AAA) repairs in the United States are performed with endovascular methods. Baseline aortoiliac arterial anatomic characteristics are fundamental criteria for appropriate patient selection for endovascular aortic repair (EVAR) and key determinants of long-term success. We evaluated compliance with anatomic guidelines for EVAR and ...

Clinical experience with coronary stent implantation in children is very limited. In-stent restenosis, thrombosis, and aneurysm formation are known complications. Recently, fracture of a drug-eluting stent was reported to be a cause of in-stent restenosis, but the natural course of stent fracture and proper management options remain uncertain. This report ...

The optimum time to treat abdominal aortic aneurysms (AAAs) still remains an uncertain issue. The decision to intervene does not take in account the effects that wall curvature, intraluminal thrombus (ILT) properties and thickness have on rupture. The role of ILT in aneurysm dynamics and rupture has been controversial. In ...

Abstract In current clinical practice, aneurysm diameter is one of the primary criteria used to decide when to treat a patient with an abdominal aortic aneurysm (AAA). It has been shown that simple association of aneurysm diameter with the probability of rupture is not sufficient, and other parameters may also ...

All patients following the Norwood I procedure have a very large ascending aorta. This can lead to extrinsic compression of the surrounding vessels. We report a case of left pulmonary artery compression secondary to an aneurysmal neo-aorta and describe a technique of posterior reduction aortoplasty to decompress the left pulmonary ...

Ascending thoracic aortic aneurysms (ATAA) were resected from patients during graft replacement and non-aneurysmal vessels during autopsy. Tissues were histomechanically tested according to region and orientation, and the experimental recordings reduced with a Fung-type strain-energy function, affording faithful biomechanical characterisation of the vessel response. The material and rupture properties disclosed ...

Despite rapid expansion of our knowledge of vascular adaptation, developing patient-specific models of diseased arteries is still an open problem. In this study, we extend existing finite element models of stress-mediated growth and remodelling of arteries to incorporate a medical image-based geometry of a healthy aorta and, then, simulate abdominal ...

Over the last decade, significant developments have been made in the treatment of structural heart disease. Some of these techniques require placement of large arterial sheaths for device delivery. Optimal vascular access is essential for successful large-vessel sheath insertion as well as to avoid vascular complications. The critical step for ...

Vascular arterial compression syndromes are uncommon disorders due to dynamic anatomic compression of an artery resulting in significant ischemia in the supplied territories with ensuing symptoms. The diagnosis of these disorders requires heightened awareness and a high index of suspicion by the clinician. These diagnoses should be particularly suspected in ...

We describe the case of a 37-year-old woman with atrial tachycardia associated to atrial septal aneurysm. We consider a localized reentry mechanism as the pathogenetic mechanism of the arrhythmia as demostrated by means of electrophisiological evaluation and electroanatomical mapping. The treatement by radiofrequency appears as an effective and well tolerated ...

AIM: The aim of this anatomical study was to define the intraosseous vascular territory of the facial artery. The clinical issue is whether ipsilateral facial artery anastomosis will guarantee blood supply to the ipsi- and contralateral mandibular symphyses and maxillae in allotransplantation. MATERIAL AND METHODS: Of 10 human cadaveric heads, ...

Our aim was to examine the relationship of arterial stiffness to measures of atherosclerosis, arterial calcification, and bone mineral density (BMD); the heritability of these measures; and the degree to which they are explained by common genetic influences. Arterial stiffening relates to arterial calcification, but this association could result from ...

Since the first human procedure in the late 1980s, vascular stent implantation has been accepted as a standard form of treatment of atherosclerosis. Despite their tremendous success, these medical devices are not without their problems, as excessive neointimal hyperplasia can result in the formation of a new blockage (restenosis). Clinical ...

INTRODUCTION: Achilles tendon ruptures, especially ruptures caused by pathologic conditions and also by achillotendinitis are often attributed to the alleged hypovascularisation of the Achilles tendon. Anatomic studies often mention an avascular plane. The purpose of this study was to re-investigate the arterial supply of the Achilles tendon. MATERIAL AND METHODS: ...

We report the case of a young man with recurrent posterior circulation strokes over the course of 6 years. Standard stroke evaluation was unremarkable until careful review of catheter angiogram and CT angiogram images revealed a bony protuberance from the occiput impinging on the left vertebral artery. Local vessel injury ...

Vascular complications after total knee arthroplasty are rare. To date, there are 7 reported cases of pseudoaneurysms affecting the popliteal artery and 6 cases affecting one of the geniculate arteries. We present a case of a geniculate artery pseudoaneurysm that shared symptoms of a deep venous thrombosis on physical examination ...

The traditional criterion of maximum transverse diameter is not sufficient to differentiate the small abdominal aortic aneurysms (AAAs) that are either prone to rupture or prone to enlarge rapidly. Wall stress may be a more reliable indicator with respect to these tasks. We review the importance of geometric features in ...

INTRODUCTION: The position of the sphenopalatine artery is essential for the endoscopic treatment of severe posterior epistaxis. This artery passes through its own foramen, which has a wide range of locations and anatomic relations. OBJECTIVE: To carry out a descriptive osteological study on the sphenopalatine foramen area. Its anatomy, size, ...

  Aortic aneurysm refers to the pathological dilatation of the normal aortic lumen involving one or several segments. Thoracic aortic aneurysms are much less common than aneurysms of the abdominal aorta. Descending thoracic aortic aneurysm leading to dissection and spontaneous rupture is a potentially catastrophic illness. Although rare, dissection and ...

A young adult presented for percutaneous treatment of a narrow aortic coarctation. A very large left subclavian artery originated immediately proximal to the coarctation. In order not to exclude or jail the left subclavian artery with a stent, a double wire technique was used. From a femoral approach, two guide ...
