Core Clinical Value Thiab Comprehensive Application Landscape Of Chiba Needle in Interventional Radiology

https://radiopaedia.org/articles/chiba-needle

Cov Chib koob, tseem hu ua Chiba biopsy koob lossis Chiba zoo koob, pib los ntawm Chiba University hauv Nyij Pooj thiab yog ib tus neeg sawv cev tshaj plaws zoo koob aspiration biopsy (FNAB) cov cuab yeej hauv kev cuam tshuam hluav taws xob. Nws cov kev qhia tshwj xeeb yog 20G-25G, nrog 21G thiab 22G yog qhov feem ntau siv. Sab nraud txoj kab uas hla yog kwv yees li 0.6-0.9 hli, thiab qhov ntev yog feem ntau 15-20 cm. Lub kaum ntse ntse bevel kaum feem ntau yog 25 degree, thiab nws nyias -walled, saj zawg zog tsim tso cai rau nws mus cuag precisely ncav cuag tob- zaum qhov txhab nyob rau hauv daim duab taw qhia.

Core Clinical Applications

• Histological / Cytological Biopsy:Raws li CT lossis ultrasound kev taw qhia, koob zoo aspiration yog ua rau pulmonary nodules, daim siab loj, qog nqaij hlav, qog raum, thiab retroperitoneal lymph nodes kom tau txais cov qauv cytological. Cov ntaub ntawv qhia tias cov neeg sawv cev ntawm tes ntawm CT- coj Chiba koob lub ntsws punctures tshaj 85%.
• Cyst Fluid / Abscess Aspiration thiab Drainage:Aspiration ntawm hepatic cysts, lub raum cysts, pancreatic pseudocysts, thiab tob abscess ntsiab lus rau kev soj ntsuam los yog kev kho decompression.
• Initial Puncture rau Percutaneous Transhepatic Cholangiography (PTC) thiab Percutaneous Transhepatic Biliary Drainage (PTBD):Ib rab koob 21G lossis 22G Chiba yog siv rau thawj zaug rau hauv cov kab mob intrahepatic bile ducts. Tom qab paub meej tias cov kua tsib rov qab los, micro-cov lus qhia tau qhia kom ua tiav qhov kev tso dej catheter tom qab.
• Tshuaj ablation thiab tshuaj txhaj tshuaj:Ua haujlwm raws li kev sib tsoo thiab tshuaj xa xov hauv ethanol lossis tshuaj txhaj tshuaj ablation kho rau mob qog noj ntshav thiab cov qog ntshav qog ntshav.
• Nerve Blocks thiab Pain Interventions:Qee lub chaw siv nws ua cov tshuaj infusion channel rau discography thiab paj hlwb blocks.

Vim li cas Chiba Koob Yog Irreplaceable

Piv rau cov koob ntxhib (xws li Tru-Txiav), rab koob Chiba ua rau muaj kev raug mob tsawg heev, nrog rau qhov tshwm sim ntawm pneumothorax thiab los ntshav tsis txaus (pneumothorax tus nqi rau lub ntsws puncture nrog 21-23G yog kwv yees li 5.1%, thaum 18G tuaj yeem ncav cuag 50%). Nws ultra-phab ntsa nyias thiab loj lumen-rau- sab nraud- txoj kab nruab nrab qhov sib piv ua kom tsis zoo-siab aspiration ntawm cov hlwb, thiab lub cev lub cev hloov tau yooj yim tso cai rau kev hloov kho zoo hauv cov ntaub so ntswg sib sib zog nqus - uas yog qhov tshwj xeeb tshaj yog rau cov kab mob uas nyob ib sab los yog cov hlab ntsha.

Cov ntsiab lus tseem ceeb ua haujlwm thiab tswj kev pheej hmoo

Cov koob txhaj tshuaj yuav tsum tau ua nyob rau hauv lub sijhawm tiag tiag- lub sijhawm ultrasound lossis CT saib xyuas, tswj xyuas qhov tsis zoo siab (mob aspiration nrog 5-10 mL syringe). Tom qab ncav cuag qhov txhab, tig thiab thrust 2-3 zaug, ces tso lub siab tsis zoo ua ntej tshem lub koob. Contraindications muaj xws li mob hnyav coagulation, tsis muaj peev xwm koom tes nrog ua pa- tuav, thiab tsis muaj txoj hauv kev nyab xeeb zam cov hlab ntsha loj lossis cov kab mob tseem ceeb. Cov teeb meem feem ntau muaj xws li pneumothorax me me, koob los ntshav, thiab cov kua tsib me me, feem ntau daws tau tus kheej lossis nrog kev kho mob.

Nrog rau kev nce qib ntawm cov tshuaj muaj tseeb, Chiba koob tau hloov zuj zus los ntawm ib qho "txhaj tshuaj" rau hauv tus choj txuas rau kev kuaj mob, cytopathology, thiab kev kho mob. Nws yog ib qho tseem ceeb hauv cov cuab yeej hauv kev cuam tshuam, chaw saib xyuas, tshuaj ua pa, gastroenterology, thiab endocrinology (rau cov thyroid nodule FNA).
