No ke aha e koho ai i ka mīkini laser diode 1470nm no ka wehe ʻana i nā veins varicose?
ʻO ke kumu o nā aʻa Varicose
ʻO ke kumu nui o nā aʻa Varicose ʻo ia ka nāwaliwali o ke ʻano o ka paia venous i loko o ka ʻōnaehana venous superficial, e alakaʻi ana i ka dilatation holomua. Hoʻopilikia kēia loli morphological i ka mākaukau o nā valves venous unidirectional, kahi ma lalo o nā kūlana physiological maʻamau e pale ai i ke kahe koko retrograde. ʻO ka hemahema o ka valve ka hopena o ka reflux venous, ʻoiai i ka wā o ke kūlana kū pololei, kahi e hoʻonui ai nā mana umekaumaha i nā dinamika kahe koko maʻamau.
Hoʻonui ke kahe retrograde mau i ke kaomi intraluminal i loko o nā veins i hoʻopilikia ʻia, e paipai ana i ka hoʻonui hou ʻana o ka venous dilation, tortuosity, a me nā hōʻike lapaʻau e like me ka ʻeha, ka edema, nā loli o ka ʻili, a i nā hihia koʻikoʻi, ka ulceration. Hoʻopili pinepine ʻia ka lawa ʻole o ka venous mau me kēia cascade pathophysiological.
ʻIkepili o Laser Endovenous Lapaʻau (EVLT)
ʻO ka Endovenous Laser Treatment (EVLT) kahi hana minimally invasive, i alakaʻi ʻia e ke kiʻi i hoʻomohala ʻia e nā loea vascular no ka mālama ʻana i ka symptomatic superficial venous reflux, ʻoi aku hoʻi e pili ana i ka great saphenous vein (GSV) a me ka small saphenous vein (SSV).
Ma lalo o ke alakaʻi ʻana o ka ultrasound, ua hoʻokomo ʻia kahi fiber laser i loko o ke aʻa i manaʻo ʻia ma o kahi catheter. ʻO ka ikehu wela i hāʻawi ʻia e hoʻoulu ai i ka hōʻino ʻana o ka endothelial, fibrosis paia o ke kīʻaha koko, a me ka occlusion ma hope. Hana pinepine ʻia ʻo EVLT ma lalo o ka anesthesia tumescent kūloko ma kahi hoʻonohonoho outpatient, me ka lōʻihi o ke kaʻina hana ma waena o 30 a 60 mau minuke.
ʻO nā pono nui:
*Nā helu holomua loea kiʻekiʻe (>90%)
*Ua hoʻemi ʻia ka ʻeha a me nā pilikia postoperative i hoʻohālikelike ʻia me nā ʻano hana kuʻuna
*Hoʻōla wikiwiki a hoʻomaka hou i nā hana o kēlā me kēia lā
*ʻO ka ʻeha liʻiliʻi a me nā hopena hoʻonaninani i hoʻomaikaʻi ʻia
Ua lilo ʻo EVLT i lāʻau lapaʻau laina mua no ka lawa ʻole o nā venous maʻi ma muli o kona pono, palekana, a me ka hiki ke hana hou ʻia.
Kumu no ka hoʻohana ʻana i Ka lōʻihi o ka nalu 1470nm
Ma waena o nā nalu laser like ʻole i hoʻohana ʻia i ka ablation endovenous, ua loaʻa i ka laser diode 1470nm ka makemake ma muli o kona mau waiwai optical kiʻekiʻe. Hōʻike kēia nalu i kahi coefficient absorption kiʻekiʻe no ka wai ma mua o ka hemoglobin, e ʻae ana i ka lawe pololei a me ka kāohi ʻana o ka ikehu thermal i ka paia vein.
ʻAno hana:
*Hoʻopili ʻia ka ikehu laser e ka ʻiʻo perivenous a me ka wai intravascular, e hana ana i nā pehu mahu e hoʻoulu ai i ka hoʻomehana circumferential o ka paia aa koko.
*Hoʻemi kēia hopena thermal indirect i ka hōʻeha photothermal pololei i ka endothelium ʻoiai e hōʻoiaʻiʻo ana i ka denaturation mau o ka collagen a me ka pani ʻana o ka lumen.
Nā pono lapaʻau:
*ʻOi aku ka haʻahaʻa o ka ikehu holoʻokoʻa no ka ablation maikaʻi
*Hoʻemi ʻia ka pilikia o ka hōʻeha wela i nā ʻano pili (e like me nā aʻalolo ʻili, ka ʻili)
*Ua emi ka nui o ka ʻeha ma hope o ke kaʻina hana, ka ecchymosis, a me nā pane mumū
*Hoʻonui ʻia ka ʻoluʻolu o ka mea maʻi a me ka hoʻōla wikiwiki ʻana i ka hana
Kākoʻo nā hōʻike e hoʻomaikaʻi ka nalu 1470nm i ka pono o ke kaʻina hana a me ka palekana me ka ʻole o ka hoʻopilikia ʻana i nā helu occlusion lōʻihi.
