In Japanese guideline for endovenous treatment of varicose vein patients, compression therapy by elastic stockings (ES) are recommended after endovenous laser ablation (EVLA). A few randomized controlled trial (RCT) reported that wearing ES reduced significantly postprocedural pain at 1 week after EVLA, although the level of evidences were weak and the effect of ES on preventing postprocedural deep vein thrombosis (DVT) was unclear. Currently, we suggest that compression therapy by ES is necessary after EVLA. Further RCT in Japan is warranted to clarify whether wearing ES prevent DVT after EVLA.

In “Wearing safety eyewear” which is important as one of safety measures for laser processing workers, there must be no mistakes in the selection property safety eyewear for the laser work. The necessary items required for safety eyewear as mentioned above are not detailed in the Ministry of Health, Labor and Welfare Circular and are also described in JIS C 6802 “Safety Standards for laser Products”, but since the selection process of safety eyewear is not described, Based on the contents of these standards, I would like to refer to summarize the points to keep in mind when using safety eyewear for the laser as safety protection measures.
“佩戴安全眼镜”是激光加工工人的重要安全措施之一，在选择激光工作的安全眼镜时，一定不能出现错误。如上所述，安全眼镜所需的必要项目在厚生劳动省的通知中没有详细说明，在JIS C 6802“激光产品安全标准”中也有描述，但由于安全眼镜的选择过程没有描述，根据这些标准的内容，我想参考总结使用激光安全眼镜作为安全防护措施时应注意的要点。

Incompetent perforating vein (IPV) is often the cause of varicose veins with skin lesions and recurrent varicose veins. There are various treatments for IPV. We studied percutaneous ablation of perforators (PAPS) using the technique of endovenous laser ablation. The effectiveness of PAPS was measured by ultrasonography to determine the presence of IPV diameter change and reflux, and the symptoms were studied using venous clinical severity score (VCSS). The value of VCSS improved in all cases. All IPV backflow stopped. The IPV diameter is an average of 5.83 ± 1.13 mm preoperatively, 3.43 ± 0.40 mm (p = 0.01) one month after PAPS, and 2.90 ± 0.88 mm (p = 0.03) three months after PAPS (using t test). All IPV diameters were significantly reduced. PAPS has made it possible to provide treatment with simple procedures by device innovation. It is useful as a treatment for varicose veins showing various conditions.
穿孔静脉功能不全是引起静脉曲张伴皮损和复发性静脉曲张的常见原因。IPV有多种治疗方法。我们研究了静脉内激光消融技术对穿支的经皮消融。通过超声检测PAPS的有效性，判断是否存在IPV内径改变和反流，并采用静脉临床严重程度评分(VCSS)对症状进行研究。VCSS值在所有情况下均有所提高。所有IPV回流停止。IPV直径术前平均为5.83±1.13 mm，术后1个月平均为3.43±0.40 mm (p = 0.01)，术后3个月平均为2.90±0.88 mm (p = 0.03)(采用t检验)。所有内径均显著减小。PAPS通过设备创新使提供简单程序的治疗成为可能。它是一种有用的治疗静脉曲张显示各种条件。

A 38 year-old female nurse was training for laser toning by Nd:YAG laser. Accidental macular hole occurred in her right eye when she was exposing laser light on the training paper contained in a clear plastic file. She didn’t wear protective goggles. Macular hole was closed by vitrectomy, but the visual acuity of her right eye deteriorated to 0.01.

In endovenous laser ablation, the vein is ablated by exceedingly hot layer of carbonized blood on the fiber tip and direct application of laser energy through the fiber. Both mechanisms coexist in actual clinical ablation. Combination of 1,470 nm laser and radial emitted fiber came into wide use recently. Recent developments are radial emitted slim fibers and a new pull-back device.

Eight years have passed since endovenous laser treatment (EVLT) for lower extremity varicose veins became available in Japan in January 2011. In this review, we will focus on the history of EVLT approval and the role of The Japanese Committee for Endovenous Laser Treatment established with EVLT approval.

Recurrent varicose veins are a common problem after endovascular laser ablation (EVLA). The major sources of recurrence after EVLA of the great saphenous vein (GSV) include recanalization and reflux into the tributaries near the junction. Neovascularization is less common after EVLA than high ligation and stripping (HLS). There are few studies investigating long-term outcomes of EVLA for small saphenous vein (SSV) insufficiency. Compared with HLS of the SSV, better short-term results of EVLA of the SSV are shown despite of the higher rate of recurrence possibly related to anatomical variations. Further investigations are needed to confirm long-term results and late recurrence after EVLA of the SSV.
