Comparison of Restenosis Risk in Single-Layer versus Dual-Layer Carotid Stents: A Duplex Ultrasound Evaluation.

Purpose: The aim of this study was to report intermediate-term results of duplex ultrasound follow-up of carotid artery stenting performed with the dual-layer stent as compared to concurrent patients treated with other commercially available single-layer carotid stents.

Materials And Methods: A single centre, retrospective, nonrandomized study including 162 non-consecutive patients with 199 implanted carotid stents treated over a 7-year period was conducted. Patients with at least one ultrasound examination after treatment were included.

Percutaneous thrombectomy in the management of early rethrombosis in venous thoracic outlet syndrome: two case reports.

Background: Venous thoracic outlet syndrome resulting in the upper limb deep venous thrombosis is known as Paget-Schroetter syndrome or effort thrombosis. A general treatment algorithm includes catheter-directed thrombolysis followed by surgical thoracic outlet decompression. There are limited data regarding endovascular treatment of rethrombosis presenting early after the surgery.

Therapeutic angiogenesis improves fibrinolytic imbalance in patients with critical limb ischemia.

The mechanisms of fibrinolysis have been suggested to be linked to the pathogenesis of peripheral artery disease. The impact of therapeutic angiogenesis on the parameters of fibrinolysis was studied in critical limb ischemia (CLI). CLI patients (N = 29) and blood donors as controls (N = 29) were enrolled.

Therapeutic angiogenesis for the critical limb ischemia decreases platelet activation.

Platelets are required for the recruitment of bone marrow-derived mononuclear cells (BMMNC) into ischemia-induced vasculature, which underlines their key role in angiogenesis. The difference in platelet immunophenotype between healthy controls and patients with critical limb ischemia (CLI) treated with therapeutic angiogenesis (TA) using BMMNC was assessed. The impact of TA on the expression of platelet membrane markers was studied as well.

Successful recanalization of acute superior mesenteric artery thromboembolic occlusion by a combination of intraarterial thrombolysis and mechanical thrombectomy with a carotid filter.

Acute superior mesenteric artery (SMA) occlusion is a life-threatening disease, and acute intestinal ischemia develops from the sudden decrease in perfusion to the intestines. The key to saving the patient's life is early diagnosis, and prompt revascularization of the SMA can prevent intestinal infarction and decrease the risk of bowel segment necrosis. Computed tomographic angiography may be useful for rapid diagnosis.

Bleeding in acute pancreatitis treated by transcatheter arterial embolization with ethylene-vinyl alcohol copolymer (Onyx).

Hemorrhagic complications are usually manifestations of the progress of severe pancreatitis. In major arterial hemorrhage resulting from pancreatic inflammatory disease, visceral angiography is valuable in localizing the site of bleeding, and hemostasis can be achieved by transcatheter arterial embolization. Successful transcatheter embolization of bleeding in the anterior superior pancreaticoduodenal artery using ethylene-vinyl alcohol copolymer (Onyx) was performed in a 38-year-old woman with acute biliary necrotic-hemorrhagic pancreatitis.
