A 61-year-old diabetic woman presented with a mycotic aneurysm of the aortic arch, also involving the left subclavian and vertebral arteries, caused by Staphylococcus aureus. Two months before, she had suffered from staphylococcal septic arthritis in her left knee. The patient was treated with antibiotics and an emergency operation was performed involving aneurysm excision and in situ synthetic...

Fig. 1 : Plain frontal chest radiographminimal cardiomegaly with notching and erosion of posterior lower rib margins (arrows). Fig. 2 : CT Aortogram showing non-opacifi cation (arrow) of aorta just distal to origin of a dilated left subclavian artery suggestive of coarctation. Fig. 3 : Dilated tortuous internal mammary and intercostal arteries on CT aortogram. Fig. 4 : Aorta distal to coarctati...

The less invasive approach should be considered the transfemoral one, nevertheless a number of patients that are referred for TAVI are not eligible for trans-femoral access due to calcification, vascular narrowing, or tortuosity of ileo-femoral arteries. For them, the transapical, subclavian, or direct aortic approaches may be a suitable alternative. The choice of alternative access should be d...

Congenital anomalies of the great thoracic vessels have been reported in 20% of dogs and cats. In some cases, the vascular ring anomalies remain unrecognized throughout the lifetime of an animal. This report describes a case with an unusual vascular ring anomaly (VRA) that was detected during dissection on a cadaver of an approximately two-year-old male native mixed breed dog. No history of the...

We present an uncommon case of a 48-year-old female patient with symptomatic presentation of a severe aortic regurgitation with aneurysm of the ascending aorta and progressive dyspnea. Detailed investigation of laboratory tests and imaging identified Takayasu's arteritis (TA) as the underlying etiology. Computed tomography scan revealed complete occlusion of the right carotid artery as well as ...

Innominate artery injury is a rare, but catastrophic complication of tracheostomy. We present a case of severe hemorrhagic shock in a 79-year-old male with innominate artery injury that occurred during tracheostomy. Despite temporary innominate artery isolation, the regional forehead saturation was 60 % without laterality. Because adequate cerebral blood flow was apparently maintained through c...

An operator's ability to determine the optimal vascular access strategy for patients undergoing peripheral endovascular intervention is critical to maximizing procedural safety and success. Individualizing an approach to access requires careful planning, and is contingent upon a solid general knowledge of normal and abnormal vascular anatomy, as well as the particulars of each patient's history...

OBJECTIVES To review the occurrence of mycotic aneurysm affecting upper extremity arteries. DESIGN Literature review. MATERIALS AND METHODS A MEDLINE search from 1950 until 2007 and an extensive manual search were carried out using bibliographies from relevant published papers including cases involving arteries distal to the subclavian. RESULTS A total of 149 cases (68 papers) were identi...

A clinical case with rare anomaly: right aortic arch with mirror-image branching of brachiocephalic arteries and aplasia (isolation) of the left brachiocephalic trunk, causing cerebrovascular insufficiency and left arm claudication is described. Despite the clear neurologic manifestations of cerebrovascular insufficiency and absence of the pulse on the left arm, the pathology was not diagnosed ...

[email protected] The use of the left internal mammary artery (LIMA) is preferred for the revascularization of a stenosed or occluded left anterior descending artery (LAD). Occlusion or stenosis of proximal part of the left subclavian artery (LSA) could induce reverse blood flow in LIMA called coronary subclavian steal syndrome (CSSS) and should be revascularized before coronary artery bypass ...
