Valuentum Securities Summary We think the future need for better patient outcomes and improved recovery times through minimally invasive surgery will be tremendous. We like that Intuitive Surgical is not resting, as it allocates more and more money into research and development every year.

There are 2 types of PVD: Functional PVD does not involve defects in the structure of the blood vessels; is usually transient and related to spasm of the vessels e.

Physicians can identify patients who are at risk for the disease with a questionnaire and the ankle brachial index ABI. Normally, the ratio is more than 1; in severe disease, it is less than 0. Those who do not improve may undergo contrast angiography or magnetic resonance angiography, which may be used in planning for surgery or percutaneous intervention.

In particular, patients with critical limb ischemia CLI should undergo interventions for re-vascularization. Re-vascularization methods have entailed surgical as well as endovascular approaches.

Self-expanding stents may have benefits in longer occlusive lesions as primary therapy, especially in the FP segment, where PTA and BE stents may be associated with higher rates of re-stenosis and failure.

The SE stent depends on the unique properties of a memory metal e. The SE stent may be post-dilated to ensure strut apposition to the arterial wall. However, animal studies did not support the proposed advantage of the covered stent that it lowers the incidence of neointimal hyperplasia, which can hasten re-stenosis.

While the incidence of neointimal hyperplasia was reduced in the mid-portion of the graft, it was comparable to that of controls at the proximal and distal ends of the covered stent.

One major advantage of a stent graft is that a longer infra-inguinal lesion can be treated. In theory, the synthetic fabric of the covered stent excludes the atherosclerotic plaque from the lumen.

In addition, the combination of the nitinol exoskeleton and the fabric cover yields a flexible, but structurally stable device, which is particularly advantageous in the femoro-popliteal segment Balk et al, Randomized controlled trials RCTs are underway, one that compares PTA alone to PTA and a biliary stent in the superficial femoral and proximal popliteal arteries; another RCT has been performed, which examines a bare nitinol biliary stent in the same anatomical segment.

Neither of these trials has yet been published in peer-reviewed journals Balk et al, Diagnosis and management" recommended the use of bare metal stents where stenting is indicated for intermittent claudication because of a lack of evidence of superior clinical outcomes with DES.

There is no consensus on the diagnosis or treatment of renal artery stenosis RAS. The consequences of renal ischemia are hypertension, neuroendocrine activation, and renal insufficiency, which can result in acceleration of atherosclerosis, further renal dysfunction, myocardial infarction MIheart failure, stroke, and death.

Whether re-vascularization improves clinical outcomes when compared with optimal medical therapy is unclear. There is insufficient evidence of the effectiveness of stenting over percutaneous transluminal angioplasty PTA for renal artery stenosis.

The American Heart Association AHA 's symposium on atherosclerotic peripheral vascular disease -- intervention for renal artery disease Rocha-Singh et al, stated that the treatment of atherosclerotic renal artery disease is evolving and remains controversial.

However, it is still unclear if percutaneous re-vascularization adds incremental value to optimal medical therapy to prevent the adverse consequence of renal artery disease. More recently published systematic evidence reviews e. Ongoing clinical trials such as the Cardiovascular Outcomes in Renal Atherosclerotic Lesions CORAL trial will ultimately help to determine the best strategies to limit the morbidity and mortality associated with renal artery stenosis.

Cooper and colleagues stated that the Cardiovascular Outcomes in Renal Atherosclerotic Lesions Trial CORAL is a randomized clinical study contrasting optimal medical therapy alone to stenting with optimal medical therapy for patients with atherosclerotic RAS on a composite cardiovascular and renal endpoint: The secondary endpoints evaluate the effectiveness of re-vascularization in important subgroups of patients and with respect to all-cause mortality, kidney function, renal artery patency, microvascular renal function, and BP control.

The number of medications for hypertension initially decreased from 2. By 6 months, however, the number of medications had increased and was not significantly different from before stent placement.

Renal function was stable in the group as a whole: When stratified by degree of renal function, values were similarly stable.The Bureau of Labor Statistics is the principal fact-finding agency for the Federal Government in the broad field of labor economics and statistics. There are lots of jobs available in Detroit, and Detroit at Work is the best place to search for all of them.
