Inferior vena cava filter presenting as chronic low back pain.

Our purpose is to report a rare complication of an inferior vena cava (IVC) filter with vertebral bone penetration, interval fracture, subsequent endovascular management and outcome. We report a case of an IVC filter embedded within the second lumbar vertebral body and in which one of the primary struts fractured, which presented as chronic low back pain. The filter was retrieved percutaneously approximately 2 years after placement.

Subintimal arterial flossing with antegrade-retrograde intervention (SAFARI) for subintimal recanalization to treat chronic critical limb ischemia.

Purpose: To describe the technique of subintimal arterial flossing with antegrade-retrograde intervention (SAFARI) to improve technical success for the performance of subintimal recanalization when there is failure to reenter the distal true lumen or when there is a limited segment of patent distal target artery available for reentry.

Materials And Methods: Subintimal recanalization was attempted in an antegrade direction in all patients. If reentry into the distal true lumen was unsuccessful or a short segment of target artery was present, retrograde access was obtained in the distal target artery (popliteal, anterior tibial/dorsalis pedis, or posterior tibial) and a retrograde subintimal channel was created.

Percutaneous intentional extraluminal recanalization in patients with chronic critical limb ischemia.

Purpose: To review percutaneous intentional extraluminal recanalization (PIER) for treatment of patients who are poor candidates for infrainguinal arterial bypass surgery (IABS) and have arterial occlusions and chronic critical limb ischemia (CCLI).

Materials And Methods: Patients with CCLI who were poor candidates for IABS were candidates for PIER. PIER was performed to create continuous arterial flow to the foot for limb salvage.

Subintimal recanalization is safe and effective in treating chronic critical limb ischemia in selected patients.

Subintimal recanalization is a percutaneous technique that allows revascularization in patients with limb-threatening ischemia. It was first described by Bolia (Cardiovasc Intervent Radiol 13;357-63:1990) but has not gained widespread use in the United States. Twenty-five patients with 32 threatened limbs were referred from a single surgeon's practice over a 23-month period.

Simultaneous antegrade and retrograde access for subintimal recanalization of peripheral arterial occlusion.

Subintimal recanalization can be a useful procedure in selected patients with severe peripheral vascular disease with tissue loss or rest pain and limited surgical bypass options. Technical failure occurs in approximately 20% of patient who undergo percutaneous intentional extraluminal recanalization due to inability to reenter the distal true lumen. A technique to improve technical success when performing subintimal recanalization when there is failure to reenter the distal true lumen or possibly when there is a limited segment of patent distal target vessel for reentry is proposed.

Percutaneous transluminal angioplasty and stenting in the treatment of chronic mesenteric ischemia: results and longterm followup.

Background: The purpose of this study was to review the results of percutaneous transluminal angioplasty (PTA), stenting, or both in the treatment of patients who present with symptoms and angiographic findings most consistent with chronic mesenteric ischemia.

Study Design: A retrospective analysis of 33 consecutive patients from a single institution who underwent PTA, stenting, or both for treatment of symptoms most characteristic of chronic mesenteric ischemia was performed.

Results: There were 12 men and 21 women with a mean age of 63 years (range 40 to 89 years).
