Intralesional injection of bleomycin in the management of low flow vascular malformations: Results and factors affecting the outcome.

Objective: Ethanol has been a commonly used sclerosant for low-flow vascular malformations, but it carries a high risk of complications. Bleomycin has been recently introduced as a potentially effective treatment. The aim of this study was to evaluate the safety and efficacy of bleomycin intralesional injection for the treatment of low-flow vascular malformations and determine the different factors affecting the outcome.

Outcome of catheter directed thrombolysis for popliteal or infrapopliteal acute arterial occlusion.

Management of acute limb ischemia (ALI) due to occlusions in popliteal and infrapopliteal arteries remains a challenge. Open surgical methods and even the novel percutaneous mechanical thrombectomy devices have not shown satisfactory results in these small arteries. The aim of this prospective study was to assess the safety and efficacy of catheter-directed thrombolysis (CDT) in this type of ALI with distal occlusion.

The Preventive Value of Epidural Calcitonin in Patients with Lower Limb Amputation.

Background: Postamputation pain is highly prevalent after limb amputation with neuropathic nature; calcitonin may effectively relieve many neuropathic pain states.

Design: Double-blind randomized multicenter study.

Setting: Our study hypothesis is to evaluate the preventive value of epidural calcitonin on postoperative pain, grade of phantom pain, and the development of allodynia and hyperalgesia in patients undergoing lower limb amputation.

Use of a percutaneous puncture needle for true lumen re-entry during subintimal recanalization of the superficial femoral artery.

Failure of subintimal angioplasty commonly results from an inability to re-enter the true lumen. When re-entry devices are not available, an alternative is the retrograde approach. This case report describes three patients with superficial femoral artery occlusion treated by endovascular intervention that showed failure of re-entry into the true lumen after the subintimal approach.
