Uvavanyo lweDoppler ultrasound ngengalo okanye umlenze

Olu vavanyo lusebenzisa i-ultrasound ukujonga ukuhamba kwegazi kwiimithambo ezinkulu kunye nemithambo ezingalweni okanye emilenzeni.

Uvavanyo lwenziwa kwisebe le-ultrasound okanye le-radiology, igumbi lesibhedlele, okanye kwilebhu ye-vascular peripheral.

Ngexesha loviwo:

• Ijeli enyibilikayo emanzini ibekwa kwisixhobo esiphathwayo esibizwa ngokuba yitransducer. Esi sixhobo sithumela amaza esandi ahamba rhoqo kumthambo okanye kwimithambo kuvavanywa.
• Uxinzelelo lwegazi cuffs inokufakwa kwiindawo ezahlukeneyo zomzimba, kubandakanya ithanga, ithole, iqatha, kunye namanqaku ahlukeneyo ecaleni kwengalo.

Kuya kufuneka ususe iimpahla engalweni okanye emlenzeni ovavanywayo.

Ngamanye amaxesha, umntu owenza uvavanyo uya kudinga ukuba acinezele emthanjeni ukuze aqiniseke ukuba ayinayo i-clot. Abanye abantu banokuziva iintlungu kancinci kuxinzelelo.

Olu vavanyo lwenziwa njengenyathelo lokuqala lokujonga kwimithambo kunye nemithambo. Ngamanye amaxesha, i-arteriography kunye ne-venography inokufuneka kamva. Uvavanyo lwenziwe ukunceda ukufumanisa isifo:

• IArteriosclerosis yeengalo okanye yemilenze
• Igazi legazi (i-vein vein thrombosis)
• Ukungoneli kwe-venous

Uvavanyo lunokusetyenziselwa:

• Jonga ukwenzakala kwimithambo
• Ukujonga ukwakhiwa ngokutsha kwemithambo kunye nokudlula kwiifomathi

Iziphumo eziqhelekileyo zithetha ukuba imithambo yegazi ayibonisi zimpawu zinciphileyo, amahlwili, okanye ukuvalwa, kwaye imithambo yegazi inegazi eliqhelekileyo.

Iziphumo ezingaqhelekanga zinokubangelwa:

• Ukuvaleka kwimithambo yegazi ngegazi
• Igazi elixineneyo emthanjeni (DVT)
• Ukunciphisa okanye ukwandiswa kwemithambo
• Isifo se-Spastic arterial disease (i-contractions ye-arterial ethe yangeniswa yingqele okanye yimvakalelo)
• Ukuvaleka komzimba (ukuvalwa komthambo)
• I-venous reflux (ukuhamba kwegazi kuhamba ngendlela engalunganga kwimithambo)
• Ukutshixwa kwemithambo yegazi kwi-atherosclerosis

Olu vavanyo lunokwenziwa ukunceda ukuvavanya le miqathango ilandelayo:

• IArteriosclerosis yeziphelo
• I-thrombosis enzulu yemithambo
• I-thrombophlebitis engaphezulu

Akukho bungozi kule nkqubo.

Ukutshaya icuba kunokutshintsha iziphumo zolu vavanyo. Inikotini inokubangela ukuba imithambo ethambileyo ifike emaphethelweni.

Ukuyeka ukutshaya kunciphisa umngcipheko weengxaki ngentliziyo kunye nenkqubo yokujikeleza kwegazi. Ukufa okuninzi okunxulumene nokutshaya kubangelwa ziingxaki zentliziyo, hayi umhlaza wemiphunga.
