This is the first study to identify oral microorganisms in the lesions of Buerger disease. Our findings suggest a possible etiologic link between Buerger disease and chronic infections such as oral bacterial infections.
Periodontopathic bacteria were present in a high percentage of specimens of diseased arteries from AAA patients and were found throughout the whole aneurysmal wall. These bacteria may play a role in the development of AAAs and/or contribute to weakening the aneurysmal wall.
A high percentage of periodontopathic bacteria were detected in atherosclerotic arterial wall specimens from patients with atherosclerosis, especially with primary atherosclerotic lesions, and most cases had severe periodontitis.
Objective: Endovenous laser ablation (EVLA) and radiofrequency ablation (RFA) are safe and effective treatments for varicose veins caused by saphenous reflux. Deep venous thrombosis (DVT) and endovenous heat-induced thrombosis (EHIT) are known complications of these procedures. The purpose of this article is to investigate the incidence of postoperative DVT and EHIT in patients undergoing EVLA and RFA. Methods: The patients were assessed by clinical examination and venous duplex ultrasonography before operation and at 24-72 hours, 1 month, and 1 year follow-up after operation. Endovenous ablation (EVA) had been treated for 1026 limbs (835 patients) using an RFA; 1174 limbs (954 patients) using a 1470-nm wavelength diode laser with radial two-ring fiber (1470R); and 6118 limbs (5513 patients) using a 980-nm wavelength diode laser with bare-tip fiber (980B). Results: DVT was detected in 3 legs (0.3%) of RFA, 5 legs (0.4%) of 1470R, and 27 legs (0.4%) of 980B. One patient in three symptomatic DVT treated with 980B developed asymptomatic pulmonary embolus. In all, 31 of the 35 DVTs were confined to the calf veins. The incidence of EHIT classes 2 and 3 was 2.7% following RFA procedure, 6.7% after 1470R, and 7.5% after 980B. Conclusion: The incidence of EHIT following EVA was low, especially the RFA procedure. EHIT resolves within 2-4 weeks in most patients. DVT rates after EVA were compared with those published for saphenous vein stripping. (This is a translation of J Jpn Coll Angiol 2015; 55: 153-161.)
Bacterial colonisation or infection of varicose veins is a frequent event although we were not able to establish whether this is a cause or consequence of the development of varices but this could be considered a risk factor for the development of varices.
It is important to investigate the anomalies of the SFJ using preoperative duplex ultrasound, although the incidence of such anomalies is lower than that of the sapheno-popliteal junction. An anomaly of the SFJ always should be taken into consideration in order to minimize surgical complications of varicose veins. (English translation of Jpn J Phlebol 2012; 23: 25-29).
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.
