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
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 (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
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 (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 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
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
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
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
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
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
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
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
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
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,
