Imaging of cauda equina edema in lumbar canal stenosis by using gadolinium-enhanced MR imaging: experimental constriction injury.

Only registered users can translate articles

OBJECTIVE It has been reported that disturbance of blood flow arising from circumferential compression of the cauda equina by surrounding tissue plays a major role in the appearance of neurogenic intermittent claudication (NIC) associated with lumbar spinal canal stenosis (LSCS). We created a model

Regional angiogenesis with vascular endothelial growth factor in peripheral arterial disease: a phase II randomized, double-blind, controlled study of adenoviral delivery of vascular endothelial growth factor 121 in patients with disabling intermittent claudication.

Only registered users can translate articles

BACKGROUND "Therapeutic angiogenesis" seeks to improve perfusion by the growth of new blood vessels. The Regional Angiogenesis with Vascular Endothelial growth factor (RAVE) trial is the first major randomized study of adenoviral vascular endothelial growth factor (VEGF) gene transfer for the

Cilostazol: a review of its use in intermittent claudication.

Only registered users can translate articles

Cilostazol (Pletal) is a selective inhibitor of phosphodiesterase-III with antiplatelet, antithrombotic and vasodilating properties. It also exhibits antiproliferative effects on smooth muscle cells and has beneficial effects on high density lipoprotein-cholesterol and triglyceride

Pathophysiology, diagnosis and treatment of intermittent claudication in patients with lumbar canal stenosis.

Only registered users can translate articles

Spinal nerve roots have a peculiar structure, different from the arrangements in the peripheral nerve. The nerve roots are devoid of lymphatic vessels but are immersed in the cerebrospinal fluid (CSF) within the subarachnoid space. The blood supply of nerve roots depends on the blood flow from both

Flow-independent angiography for peripheral vascular disease: initial in-vivo results.

Only registered users can translate articles

Flow-independent angiography (FIA), an approach that isolates arterial blood using MR relaxation characteristics rather than flow effects, was evaluated for application in peripheral vascular disease (PVD). First, pilot studies were conducted in which FIA coronal projection images were obtained from

[Blunt trauma with combined femoral arterial and venous occlusion].

Only registered users can translate articles

Blunt trauma to common femoral artery is rare, and it is frequently unrecognized. A 61-year-old man who fell while carrying a log and struck on his right groin, presented right leg edema and intermittent claudication one month later. Both right femoral arterial and venous occlusion was suspected by

Continuous lumbar sympathetic block.

Only registered users can translate articles

A 74-year-old woman with peripheral vascular disease suffered from rest pain in the right big toe and intermittent claudication. Because of concomitant venous congestion, a chemical lumbar sympathectomy was considered to carry an increased risk of leg edema. A continuous lumbar sympathetic block

Early revascularization after admittance to a diabetic foot center affects the healing probability of ischemic foot ulcer in patients with diabetes.

Only registered users can translate articles

OBJECTIVE There is limited information about whether time from recognition of decreased perfusion to revascularization affects the probability of healing in a patient with a diabetic foot ulcer. The aim of the present study was to examine whether time to revascularization after referral to a

Endovascular embolization of symptomatic arteriovenous fistulas secondary to lower-limb in situ venous bypass grafts.

Only registered users can translate articles

OBJECTIVE To evaluate the safety and efficacy of endovascular treatment of symptomatic arteriovenous (AV) fistulas associated with femoropopliteal in situ venous bypass grafts. METHODS Twenty-one patients underwent embolization of symptomatic AV fistulas associated with lower-limb bypass with use of

[Clinical study of spinal dural arteriovenous fistula-with special reference to neurological symptoms and magnetic resonance imaging].

Only registered users can translate articles

We have evaluated the backgrounds, neurological symptoms, signs, and magnetic resonance images (MRI) in six cases of spinal dural arteriovenous fistula. The subjects were 2 males and 4 females, and the mean age was 67.2 years old. The cardinal subjective symptoms were progressive motor weakness of

Concomitant Occlusive Vascular Lesions of Legs in Patients with Degenerative Lumbar Diseases: Do These Lesions Influence Treatment?

Only registered users can translate articles

OBJECTIVE Vascular narrowing or obstruction reduces blood flow to the lower limbs during exercise or at rest. Symptoms may range from intermittent claudication to pain at rest. Narrowing of these arteries may produce pain in the buttocks, thighs, or legs. These symptoms may resemble those of lumbar

Circulatory dynamics of the cauda equina in lumbar canal stenosis using dynamic contrast-enhanced magnetic resonance imaging.

Only registered users can translate articles

BACKGROUND There has been no study regarding the cauda equina circulation of patients with neurogenic intermittent claudication (NIC) in lumbar spinal canal stenosis (LSCS) using dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). OBJECTIVE The mechanism responsible for the onset of NIC

Supersized Atheroma Causing Acquired Coarctation of Aorta Leading to Heart Failure.

Only registered users can translate articles

Calcified atheromatous aortic lesion causing significant narrowing of the aorta is an uncommon clinical entity. This calcified atheroma leads to obstruction of the lumen of the aorta simulating acquired coarctation of aorta causing impaired perfusion of lower limbs, visceral ischemia, and

Ruptured aortic aneurysm masquerading as phlegmasia cerulea.

Only registered users can translate articles

Phlegmasia cerulea dolens, characterized by the triad of limb swelling, cyanosis, and acute ischemic pain, usually arises because of acute massive thrombosis of major deep, collateral, and superficial veins of an extremity. We report a patient with an atypically presenting ruptured aortic aneurysm

[Simultaneous intervention on the carotid artery, abdominal aorta and their branches].

Only registered users can translate articles

A simultaneous approach to revascularization for combined coronary and carotid disease today is well accepted. The discussion about combined procedures of carotid and aortoiliac occlusive disease is still going on. We operated upon 3 patients, aged 63,56 and 65 years, who suffered from carotid,
