Sanyayyun halitta suna da tasiri sosai a lokacin ciwon maganin thyroid
Ga mutane da yawa, kalmar "isthmus" tana nufin fili mai zurfi na ƙasar da ke kewaye da ruwa wanda ya haɗu da ƙananan ƙasa guda biyu.
Idan aka yi amfani da shi a cikin aikin likita, yana nuna wani abu kamar haka: ɓarnaccen sashi, sashi, ko sashi na nama wanda ya haɗa da manyan sassa biyu. Ana iya amfani dashi a kunnuwa (ismus of tubes Eustachian), mahaifa (isthmus na mahaifa), kwakwalwa (isthmus of cingulate gyrus) da kuma glanden thyroid (isthmus na thyroid).
Yana a cikin wannan ƙarfin na ƙarshe - a matsayin ɓangare na thyroid - cewa aiki na isthmus yana ɗaukar mafi muhimmanci a lokacin magani na ciwon daji.
Ayyukan Isthmus na Thyroid
Jirgin shine nau'in da ke samar da gada a tsakanin lobes biyu na thyroid kuma yana aiki a matsayin abin rufewa don zobba biyu na windpipe (trachea). Gwajin kanta shine gland shine mai launin fata a gaban kambin da ke ƙarƙashin larynx.
Glandar thyroid yana sarrafa tsarin jikin ta jiki ta hanyar ɓoye kwayoyin halittar da ke da iko da zafin jiki, ci gaba, ƙarfin tsoka, ci abinci, da kuma lafiyar zuciyarka, kwakwalwa, kodan, da kuma tsarin haihuwa. Gwargwadon ƙwayar yana samuwa ne kawai don tallafawa da kuma gyara waɗannan gabobin.
Rarraban Thyroid Gland da Isthmus
Kyakkyawan maganin kawanci yana da kimanin kashi ɗaya cikin huɗu kuma yawanci ba za'a iya ji ko gani ba ta fata. Ya bambanta, ƙwayar thyroid (wanda ake kira goiter) zai iya duba ko jin kamar dunƙule a gaban wuyansa.
Cigar kawanci yana iya samun matsalolin da ke ɓoye adadin hormones a jiki. Hanyoyin hormone (yanayin da ake kira hyperthyroidism ) na iya haifar da asarar nauyi, suma, zafi ciwon ciki, mahaukaci, da kuma zawo. Ƙananan ( hypothyroidism ) kuma mutum zai iya samun nauyi, ji sanyi, kuma yana da fata mai gashi ko gashi.
Abubuwan da ke tattare da issmus sun hada da agenesis (rashin isthmus saboda mummunan haihuwar haihuwa) ko raunin kai tsaye (yawanci a haɗuwa da ɗaya ko biyu lobes).
Duk wani mummunan aiki a cikin aikin thyroid zai haifar da likitanka don auna matakan da ke cikin jinin thyroid-stimulating hormone (TSH). Sauran kimantawa na iya hada da:
- nazarin jiki na wuyansa, thyroid, trachea, da kuma lymph nodes don bincika kumburi ko sabon abu growths
- ultrasonography, na'urar na'ura wanda ke amfani da raƙuman sauti na ultrasonic
- radionuclide nazarin wanda yana amfani da adadin abin da ya kunsa na rediyo don nuna haske ga nodules a lokacin hotunan
- biopsy na thyroid nama
Ana cire Yourroid da Isthmus
Idan biopsy ya nuna kasancewar ciwon daji a cikin thyroid, za a iya cire sassa na glander thyroid. Wannan hanya, wanda ake kira thyroidectomy, zai iya haɗa da cire daya ko biyu lobes. Idan ciwon ciwon ya zama m (yadawa bayan tasirin magungunan asali), mai yiwuwa ne a cire shi a cikin hanyar da ake kira isthmectomy.
Akwai hanyoyi daban-daban na thyroidectomy akan yadda za a cire glandan:
- Total thyroidectomy (kau da dukan thyroid gland shine yake)
- Yourroid lobectomy (kau da guda lobe)
- Sakamakon yaduwar maganin karoid (cire kauyen lobe)
- Yourroid lobectomy tare da isthmectomy (kau da lobe da isthmus)
- Subtotal thyroidectomy (kawar da dukan lobe, isthmus da wani m lobe)
