Duplex Ultrasound Scan for Varicose Veins - Explanation and Demonstration
Video: Duplex Ultrasound Scan for Varicose Veins - Explanation and Demonstration

Duplex ultrasound ke teko ea ho bona hore na mali a tsamaea joang methapong le methapong ea hau.

Duplex ultrasound e kopanya:

  • Ultrasound ea setso: Sena se sebelisa maqhubu a molumo a thellang methapong ea mali ho etsa litšoantšo.
  • Doppler ultrasound: Sena se tlaleha maqhubu a molumo a bonts'ang lintho tse tsamaeang, joalo ka mali, ho lekanya lebelo la tsona le likarolo tse ling tsa hore na li phalla joang.

Hona le mefuta e fapaneng ea litlhahlobo tsa duplex ultrasound. Tse ling li kenyelletsa:

  • Arterial le venous duplex ultrasound ea mpa. Teko ena e hlahloba methapo ea mali le phallo ea mali ka mpeng.
  • Carotid duplex ultrasound e sheba methapo ea carotid molaleng.
  • Duplex ultrasound ea lipheletsong e sheba matsoho kapa maoto.
  • Renal duplex ultrasound e hlahloba liphio le methapo ea tsona ea mali.

U kanna ua hloka ho apara seaparo sa bongaka. U tla robala tafoleng, 'me setsebi sa ultrasound se tla jala gel sebakeng se lekiloeng. Jel e thusa maqhubu a molumo ho kena liseleng tsa hau.


Leqhubu, le bitsoang transducer, le tsamaisoa sebakeng se lekiloeng. Leqhubu lena le romela maqhubu a molumo. K'homphieutha e lekanya hore na maqhubu a molumo a khutlela morao joang, 'me e fetola maqhubu a molumo hore e be litšoantšo. Doppler e etsa modumo wa "swishing", e leng modumo wa madi a hao a tsamayang hara methapo le methapong.

U hloka ho khutsa nakong ea tlhahlobo. O ka kopuoa ho bua leshano maemong a fapaneng a mmele, kapa ho hema hanyane ebe oa o ts'oara.

Ka linako tse ling nakong ea duplex ultrasound ea maoto, mofani oa tlhokomelo ea bophelo a ka bala index ea ankle-brachial (ABI). U tla hloka ho roala li-cuffs tsa khatello ea mali matsohong le maotong bakeng sa tlhahlobo ena.

Nomoro ea ABI e fumanoa ka ho arola khatello ea mali leqaqailaneng ke khatello ea mali letsohong. Boleng ba 0,9 kapa ho feta bo tloaelehile.

Hangata, ha ho na litokisetso tsa tlhahlobo ena.

Haeba u e-na le ultrasound ea mpa ea hao, u ka 'na ua botsoa hore u se ke ua ja kapa ua noa ka mor'a khitla. Bolella motho ea etsang tlhahlobo ea ultrasound haeba u noa meriana efe kapa efe, joalo ka lisepa mali. Tsena li ka ama liphetho tsa tlhahlobo.


U kanna oa utloa khatello ha leqhubu le ntse le sisinyeha 'meleng, empa ha ho na pherekano boholo ba nako.

Duplex ultrasound e ka bontša hore na mali a phalla joang likarolong tse ngata tsa 'mele. E ka tseba le bophara ba sejana sa mali mme ea senola lithibelo life kapa life. Teko ena ke khetho e sa hlaseleheng hofeta arteriography le venography.

Duplex ultrasound e ka thusa ho fumana maemo a latelang:

  • Aneurysm ea mpeng
  • Ho koaloa ha methapo
  • Ho koala mali
  • Lefu le hlahang la Carotid (Bona: Carotid duplex)
  • Lefu la vascular vascular
  • Metsing ea varicose
  • Ho hloka matla ha venous

Le renal duplex ultrasound le eona e ka sebelisoa kamora 'opereishene ea ho kenya. Sena se bontša hore na liphio tse ncha li sebetsa hantle hakae.

Sephetho se tloaelehileng ke phallo e tloaelehileng ea mali ka methapong le methapong. Ho na le khatello ea mali e tloaelehileng 'me ha ho na letšoao la ho fokotseha kapa ho koaloa ha methapo ea mali.

Sephetho se sa tloaelehang se latela sebaka se itseng se hlahlojoang. Phello e sa tloaelehang e ka ba ka lebaka la ho koaloa ha mali kapa ho hahoa ha lesela ka har'a sejana sa mali.


Ha ho na likotsi.

Ho tsuba ho ka fetola sephetho sa ultrasound ea matsoho le maoto. Sena se etsahala hobane nikotine e ka etsa hore methapo ea pelo e fokotsehe (e be thata).
