Either Dacron or PTFE grafts can be used in femoropopliteal bypass grafting with no significant differences in midterm graft patency at 5 years (49.2% vs 38.4%) when the autologous saphenous vein is unavailable.
The results of our analysis suggest that population-based screening for AAA reduces AAA-related long-term mortality by 4 per 1000 over control in men aged ≥ 65 years. Whereas, screening for AAA shows a strong trend toward a significant reduction in all-cause long-term mortality by 5 per 1000, which does not narrowly reach statistical significance.
Statin therapy is associated with less expansion rates in patients with small AAA. To confirm our results and more accurately assess the effect of statins on AAA expansion, a large randomized trial is needed.
Lung segmental resection is of two types: a simple type with resection of only one intersegmental plane, such as lingual or superior segmentectomy; and a complicated type with resection of two or more intersegmental planes, such as anterior segmentectomy. We present a method of identifying the intersegmental plane by physiological function. First, we cut the segmental pulmonary artery and vein. The entire lobe is then inflated with pure oxygen for 5 min. Immediately after oxygen inflation, the segmental bronchus is deflated and stapled. After a couple of minutes, the intersegmental plane is easily detected. In 117 patients who underwent segmentectomy, mean blood loss was 122 ± 193 ml and mean duration of drainage was 3.5 ± 4.8 days. Postoperative complications related to operative procedures occurred in 14 cases (12.0%). Our method of detecting intersegmental planes is convenient and useful for subsegmental resection, particularly for complicated-type cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
