Wavelet analysis of skin perfusion to assess the effects of FREMS therapy before and after occlusive reactive hyperemia.

Laser Doppler Fluxmetry is used to evaluate the hemodynamics of skin microcirculation. Laser Doppler signals contain oscillations due to fluctuations of microvascular perfusion. By performing spectral analysis, six frequency intervals from 0.

Amputation rate and mortality in elderly patients with critical limb ischemia not suitable for revascularization.

In spite of recent progress in revascularization and anesthesiology procedures, in vascular centers today there are still patients with Critical Limb Ischemia (CLI) who are not considered suitable for revascularization. Most of these patients are elderly, with high co-morbidity factors, poor run off arterial limb vessels, and often with a salvageable limb. They are absent or neglected in the literature, and generally go untreated.

Sulodexide in the treatment of chronic venous disease.

Chronic venous disease encompasses a range of venous disorders, including those involving the lower limbs resulting from venous hypertension. The spectrum of chronic venous disease signs and symptoms shows variable severity, ranging from mild (aching, pain, and varicose veins) to severe (venous ulcers). The pathophysiology of chronic venous disease is characterized by venous hypertension, which triggers endothelial dysfunction and inflammation leading to microcirculatory and tissue damage, and eventually to varicose veins and venous ulcers.

Videocapillaroscopy study of post traumatic lower limb loss of tissue treated with and without acellular dermal substitute.

A 46 years old male with a post traumatic loss of tissue localized on the anterior surface of the right thigh and knee due to a road accident, was treated with different surgical reconstructive techniques. Combined use of autologous skin graft and acellular dermal substitute Integra® allowed the satisfactory recovery of the patient who was discharged after 82 days from the trauma. To analyse the characteristics and the quality of the healing tissues we performed a videocapillaroscopy study to assess the microcirculatory pattern of the autologous skin grafted on the dermal substitute in comparison with the autologous skin grafted on granulation tissue.

Benign outcome of objectively proven spontaneous recanalization of internal carotid artery occlusion.

Objective: Spontaneous recanalization of intracranial internal carotid artery (ICA) occlusion is frequent in embolic strokes. Spontaneous recanalization of the extracranial portion of the ICA occlusion of atherosclerotic or embolic origin is only anecdotally reported, and data are lacking about its incidence, natural history, and outcome in long-term follow-up.

Methods: Consecutive patients with ICA occlusion were prospectively identified and followed-up to detect the incidence of a spontaneous recanalization.

Low-molecular-weight heparin versus compression stockings for thromboprophylaxis after knee arthroscopy: a randomized trial.

Background: Knee arthroscopy, the most common orthopedic operation worldwide, carries a definite risk for deep venous thrombosis; however, postsurgical thromboprophylaxis is not routinely recommended.

Objective: To evaluate whether low-molecular-weight heparin (LMWH) better prevents deep venous thrombosis and does not cause more complications than graduated compression stockings in adults having knee arthroscopy.

Design: Assessor-blind, randomized, controlled trial.

Levo-propionyl-carnitine improves the effectiveness of supervised physical training on the absolute claudication distance in patients with intermittent claudication.

The mechanisms by which supervised physical training improves walking ability in patients with intermittent claudication (IC) are microcirculatory, rheological, and metabolic. The main mechanism of levo-propionylcarnitine (LPC) is metabolic; it increases the walking ability in claudicants, providing an additional energy to the ischemic muscle by an anaplerotic activity. Therefore, the current study was carried out to ascertain whether the combined treatment has a synergistic effect.

The ILAILL study: iloprost as adjuvant to surgery for acute ischemia of lower limbs: a randomized, placebo-controlled, double-blind study by the italian society for vascular and endovascular surgery.

Summary Background Data: High rate of complications has been reported following revascularization for acute limb ischemia (ALI). No adjuvant pharmacologic treatment, apart from anticoagulation and standard perioperative care, has been shown clinically effective.

Objective: Aim of this study was to evaluate the effects of the prostacyclin analog iloprost as adjuvant to surgery for ALI.

Ultrasound evaluation of carotid artery in primary hyperparathyroidism.

Patients with primary hyperparathyroidism (PHPT) have an increased cardiovascular morbidity and mortality. Elevated serum calcium and/or PTH may directly contribute to vascular tissue damage, but the role of classic factors for atherosclerosis has not fully been evaluated in this disease. The aim of our study was to dissect the potential effect of hypercalcemia and/or high PTH from that of major cardiovascular risk factors (i.

L-propionyl-carnitine protects tissues from ischaemic injury in an 'in vivo' human ischaemia-reperfusion model.

Objective: To assess the acute effects of L-propionyl-carnitine (LPC) on vaso-motion, tissue perfusion and tissue acidosis during an ischaemia-reperfusion test in patients with intermittent claudication.

Design: Open pharmacodynamic study.

Study Participants: Sixteen male patients with intermittent claudication (mean absolute claudication distance 193.

High versus low doses of unfractionated heparin for the treatment of superficial thrombophlebitis of the leg. A prospective, controlled, randomized study.

Background And Objectives: The optimal treatment of superficial thrombophlebitis of the leg is undefined. The main study objective was to assess the efficacy and safety of unmonitored high doses as compared to low doses of unfractionated heparin (UFH) for prevention of venous thromboembolic complications in patients with superficial thrombophlebitis of the thigh.

Design And Methods: Sixty consecutive patients with acute thrombophlebitis of the great saphenous vein, as assessed by ultrasonography, were randomized to subcutaneous injection twice daily of UFH in high unmonitored doses (12,500 IU for one week followed by 10,000 IU) or prophylactic doses (5,000 IU) for four weeks.
