Background: Open venous ulcers in patients with combined arterial and venous insufficiency are notoriously hard to treat. Patients with an ankle-brachial index (ABI) of 0.5-0.8 have been shown to heal poorly. Because adequate compression therapy is contraindicated in patients with an ABI of <0.7) were treated using a protocol that required performing percutaneous revascularization before ambulatory compression therapy. The patients were followed at 2-week intervals (average) before and after revascularization. Wound measurements and time to complete closure were also recorded. Results: The results of the patients were compared with their own previous wound healing trajectories. Additionally, their healing rate was compared with previously published rates of impaired arterial perfusion venous wound closure; 25% closure at 10 weeks, 50% at 19 weeks. At enrollment, the average ABI and wound sizes were 0.56 and 12 cm^2, respectively. On average, the wounds had remained open for 17 weeks. After the intervention, the average ABI was 0.97, average time taken to complete closure was 10 weeks, closure rate at 10 weeks was 75%, and absolute closure rate was 100%. Conclusion: Although previous studies have shown that closure of mixed arterial venous ulcers occur without arterial intervention, attaining a near normal ABI allows for timelier wound closure. Therefore, we advocate an aggressive approach of percutaneous revascularization in this population.

    Smoking status, bronchial histology, and gender were significantly associated with Ki-67 index. No increase in Ki-67 index was found in the nonmalignant epithelium of patients with lung cancer or COPD. Although Ki-67 index may provide insight into the short-term effects of chemoprevention agents on...
