Annals of vascular diseases 12(4) 514-518 2019年12月25日 査読有りObjective: Saphenous varicose veins can be accomplished by various operative techniques that result in stripping, ablation, or ligation of the venous reflux section. Great saphenous vein (GSV) stripping is one of the standard operations for varicose veins to eliminate reflux of the sapheno-femoral junction. The goal of any treatment regimen is to eliminate the junctional varicose reflux to control congestive dysfunction. Endovenous laser ablation (EVLA) is safe and effective with less postoperative pain, bleeding, and peripheral nerve damage than open surgery. In this study, a patient with severe progression of primary saphenous varicose veins is presented. We report the outcome of combined surgical strategy and perioperative treatment for extremely swollen varicose veins of the lower limbs to improve leg symptoms and congestion and/or promote skin ulcer healing. Materials and Methods: The subjects included 42 patients (51 limbs) who underwent EVLA with stripping. The patients comprised 24 males and 18 females, who presented a maximum GSV diameter >15 mm. The Clinical-Etiological-Anatomic-Pathophysiologic classification identified 9, 20, 9, 2, 6, and 5 limbs with C2, C3, C4a, C4b, C5, and C6, respectively, among the 42 patients. Results: EVLA was used to treat GSV with a mean length of 16.1±2.8 cm. The mean of the maximum GSV diameter was 16.8±3.2 mm (14.6-21.8 mm). The preoperative visual analog scale (VAS) score was 82.1±12.1. After operation, the VAS gradually deteriorated to 31.3±17.9 (p<0.0001), 2.8±3.6 (p<0.0001), and 1.2±1.8 (p<0.0001) in 7 days, 1 month, and 3 months, respectively. Conclusion: We obtained a satisfactory outcome from our combined strategy and perioperative treatment for extremely swollen saphenous varicose veins. This approach may show the possibility that lower saphenous varicose veins can induce cosmetic and minimally invasive ameliorated intervention to avoid late-phase incompetent perforating veins.

Annals of vascular surgery 46 367.e7-367.e10 2018年1月 査読有りA venous aneurysm is a relatively rare disease defined by cystic vasodilated lesions in a general vein. Popliteal venous aneurysm (PVA) is a rare clinical entity, and the first signs may be a thromboembolic event. They can cause potentially life-threatening diseases, such as pulmonary embolism and deep venous thrombosis. A left-sided inferior vena cava (IVC) is a common anomaly associated with venous thrombus, resulting in anatomical variations in the venous return from the lower limbs. The general vascular malformation of PVA and left-sided IVC should also be preoperatively understood because of the unpredictable risk of thromboembolic complications.

日本血管外科学会雑誌 20(3) 675-679 2011年4月症例は81歳、男性。左下肢腫脹出現し当科紹介。CTで腹部大動脈・両側総腸骨動脈瘤および右総腸骨動脈瘤と左総腸骨静脈との動静脈瘻を認めた。腹部超音波検査でも右総腸骨動脈瘤から左総腸骨静脈へのシャントを認め、瘻孔の大きさは14mmであった。左外腸骨-大腿静脈に血栓を認め左下肢深部静脈血栓症を合併していた。腹部大動脈瘤、両側総腸骨動脈瘤、右総腸骨動脈-左総腸骨静脈動静脈瘻、左下肢深部静脈血栓症の診断の元に術前に一時的下大静脈フィルターを留置し手術を行った。用手的圧迫により動静脈瘻を動脈瘤内より単純縫合閉鎖、Y型人工血管置換術を施行した。動静脈瘻の有無と部位を術前に同定することにより安全に手術が行えた。(著者抄録)

Circulation journal : official journal of the Japanese Circulation Society 75(3) 550-6 2011年 査読有りBACKGROUND: The Physiological and Operative Severity Score for enUmeration of Mortality and morbidity (POSSUM), which consists of a physiological score (PS) and an operative severity score, is useful in determining the risk profile for patients with abdominal aortic aneurysms in Western countries, but no information is available on the use of this method in Japan. METHODS AND RESULTS: A retrospective cohort study involving 225 patients was performed, and the prognostic factors for morbidity and in-hospital mortality including POSSUM were investigated. The morbidity rate was 26%. On univariate analysis age, renal disease, hemoglobin, albumin, operation time, blood loss and PS were significantly different. On multivariate analysis PS was significantly different. Using receiver operating characteristic (ROC) analysis, PS had an area under the curve (AUC) of 0.712 and the best cut-off point was 18. The in-hospital mortality rate was 2.2%. On univariate analysis renal disease, albumin and PS were significantly different, and on multivariate analysis PS was significantly different. On ROC analysis PS had an AUC of 0.921 and the best cut-off point was 22. CONCLUSIONS: PS was the only independent risk factor for morbidity and in-hospital mortality. Further studies may be required to develop a risk-scoring system.

Surgery today 40(12) 1129-36 2010年12月 査読有りPURPOSE: In Japan, the incidence of venous thromboembolism (VTE), including deep venous thrombosis (DVT) and pulmonary embolism (PE), has been relatively low; however, the incidence has recently been increasing. Since April 2004, we have developed an original computer-linked VTE prophylaxis in order to decrease the incidence of in-hospital VTE. Our objective has been to evaluate the efficacy of the VTE prophylaxis guideline. METHODS: A retrospective pre- and postintervention study was conducted (preintervention phase, n = 17 854; postintervention phase, n = 26 831). Data were obtained from the clinical records of patients who underwent vascular surgery and were screened for DVT at our institution. RESULTS: The frequency of patients screened for DVT increased significantly from 70 (0.4%) to 209 (0.8%) after the establishment of a guideline (P < 0.001). Asymptomatic DVT patients increased from 5 (12.5%) in the control group to 33 (50.0%) in the intervention group (P < 0.0001), while symptomatic DVT events with leg swelling decreased from 29 (72.5%) to 16 (24.2%) (P < 0.0001). Furthermore, shock and massive PE events were significantly lower (from 31.3% to 0%; P < 0.05). CONCLUSION: Our VTE prophylaxis guidelines are considered to be useful for the detection of asymptomatic DVT patients during hospitalization, thus leading to a significantly lower incidence of postoperative VTE.

日本血管外科学会雑誌 19(4) 557-560 2010年6月左足背が壊死した75歳男性に腓腹動脈へのバイパス術を施行した。血管造影では、左外腸骨動脈、総大腿動脈、浅大腿動脈、大腿深動脈起始部、膝窩動脈、下腿3動脈は閉塞し、後脛骨動脈が下腿末梢部でかすかに開存していた。術式は、右大腿-左腓腹動脈-後脛骨動脈バイパスを予定した。手術時、後脛骨動脈は切開時内腔から血流が認められなかったため後脛骨動脈へのバイパスは断念し、自家静脈を用いて右大腿-左腓腹動脈バイパス術を施行した。術後下腿切断を要したが、腓腹動脈バイパスにより大腿切断を免れ膝関節を温存することができたと考えられる症例を報告する。(著者抄録)
