Transpedal approach for femoral-popliteal chronic total occlusions using the outback® elite re-entry device.

Background: Transpedal access is increasingly utilized for the treatment of peripheral artery disease (PAD). Femoral-popliteal artery chronic total occlusions (CTOs) are some of the most difficult lesion subsets that sometimes require the use of re-entry support devices during percutaneous intervention. Limited data is available on the use of re-entry devices when treating femoral-popliteal CTOs via transpedal access.

Delayed Presentation of a Large Pseudoaneurysm in the Common Femoral Artery After an Electrophysiology Study.

We describe a rare case of an exceptionally large pseudoaneurysm that developed in the right common femoral artery 6 months after an electrophysiological study. Surgical and other conventional methods to treat his pseudoaneurysm were not feasible. Therefore, the pseudoaneurysm was successfully treated via an endovascular approach with a covered stent.

Advances in trans-ulnar intervention: a successful trans-ulnar artery approach for left subclavian artery stenosis.

Techniques for vascular intervention have been evolving in the past decades. Trans-radial artery access (TRA) has been emerging and is favorable over trans-femoral access in recent years due to the lower risk of bleeding complications, vascular injury, early mobilization, shorter hospitalization and lesser cost. TRA has its own limitations such as radial artery stenosis, dissection, spasm and crossover.

Assessment of isotropic calcium using 0.5-mm reconstructions from 320-row CT data sets identifies more patients with non-zero Agatston score and more subclinical atherosclerosis than standard 3.0-mm coronary artery calcium scan and CT angiography.

Background: The presence of calcified plaque in coronary arteries can be quantified by using 0.5-mm isotropic reconstructions from 320-row CT without increased radiation dose. Little is known about reclassification of patients with non-zero Agatston scores and quantitative measures of calcified plaque using 0.

Triple Diuretics and Aquaretic Strategy for Acute Decompensated Heart Failure due to Volume Overload.

Diuretics, including furosemide, metolazone, and spironolactone, have historically been the mainstay of therapy for acute decompensated heart failure patients. The addition of an aquaretic-like vasopressin antagonist may enhance diuresis further. However, clinical experience with this quadruple combination is lacking in the acute setting.

Cellular antioxidant properties of human natural killer enhancing factor B.

The protein, NKEF (natural killer enhancing factor), has been identified as a member of an antioxidant family of proteins capable of protecting against protein oxidation in cell-free assay systems. The mechanism of action for this family of proteins appears to involve scavenging or suppressing formation of protein thiyl radicals. In the present study we investigated the antioxidant protective properties of the NKEF-B protein overexpressed in an endothelial cell line (ECV304).
