Key Difference – PVD vs PAD
PVD (Peripheral Vascular Disease) yog ib lo lus dav uas siv los piav txog cov kab mob ntawm cov hlab ntsha sab nraud ntawm lub hlwb thiab lub plawv. Qhov no feem ntau suav nrog cov hlab ntsha loj thiab me, cov hlab ntsha, capillaries thiab venules uas xa cov ntshav mus rau thiab los ntawm sab sauv thiab sab qis, ob lub raum thiab cov hnyuv. PVD feem ntau tuaj yeem yog ob hom xws li; Organic PVD thiab Functional PVD. Hauv cov organic PVD, cov qauv kev puas tsuaj xws li o, cov ntaub so ntswg puas, thiab occlusion ntawm cov hlab ntsha tshwm sim whereas, nyob rau hauv kev ua haujlwm PVD, tsis muaj xws li kev puas tsuaj ntawm cov hlab ntsha. PAD (Peripheral Arterial Disease) yog hom organic PVD. Hauv PAD, atherosclerotic plaques tsim nyob rau hauv cov phab ntsa ntawm cov hlab ntsha, occluding lub lumen ntawm cov hlab ntsha thiab ua rau muaj kev hloov pauv hauv cov ntshav ntws. Yog li, qhov sib txawv tseem ceeb ntawm PVD thiab PAD yog tias PAD yog ib lub ntsiab lus dav hais txog ntau yam kab mob uas muaj feem xyuam thaum PAD yog ib pawg ntawm cov kab mob vascular uas poob rau hauv qeb loj, PVD.
PVD yog dab tsi?
PVD lossis kab mob peripheral vascular tau dhau los ua ib yam mob niaj hnub no thiab tuaj yeem ua rau lub cev tsis muaj zog lossis ua rau lub neej. Yeej, PVD yog tshwm sim los ntawm qhov txo cov ntaub so ntswg perfusion tshwm sim raws li qhov tshwm sim ntawm atherosclerosis nrog thrombi lossis emboli. PVD tsis tshua pom muaj qhov mob tshwm sim tab sis qhia tau tias muaj kev mob tshwm sim ntev. Feem ntau, PVD yog asymptomatic, tab sis nyob rau hauv cov xwm txheej zoo li mob limb ischemia, yuav tsum tau muaj kev cuam tshuam tam sim los txo cov neeg tuag thiab mob.
PVD lossis atherosclerosis obliterans feem ntau tshwm sim vim atherosclerosis. Atherosclerotic plaques, uas yog tsim los ntawm lub hauv paus necrotic cores ntawm cov roj cholesterol crystals thiab lub ntsej muag fibrous cap ntawm cov leeg nqaij leeg thiab ntom collagen tuaj yeem txhim kho kom tshem tawm cov hlab ntsha nruab nrab thiab loj. Thaum cov ntshav muab rau cov extremities raug txiav tawm los ntawm thrombi, emboli los yog kev raug mob, qhov no ua rau PVD. Kev tsim ntawm thrombi feem ntau tshwm sim nyob rau hauv qis qis dua li ntawm sab sauv qaum. Cov yam ntxwv xws li kev tso zis tsis tshua muaj siab, aneurysms, ntshav siab qis, atherosclerosis, arterial grafts, thiab sepsis tuaj yeem ua rau muaj thrombosis.
Daim duab 01: Cov Teeb Meem ntawm Atherosclerosis
Sudden occlusion ntawm cov hlab ntsha tuaj yeem tshwm sim vim emboli. Cov neeg mob tuag vim yog emboli siab vim tias cov ceg ceg tsis muaj sijhawm txaus los tsim cov khoom lag luam txhawm rau txhawm rau txhawm rau them cov ntshav tsis txaus. Emboli feem ntau nyob ntawm qhov chaw ntawm arterial bifurcation thiab nyob rau hauv cov hlab ntsha nrog ib tug nqaim lumen. Qhov chaw tshaj plaws ntawm bifurcation thaiv los ntawm emboli yog femoral artery bifurcation. Kev sib koom ua ke ntawm PVD nrog cov kab mob coronary artery qhia tau tias muaj kev pheej hmoo ntawm atheroma.
Lub luag haujlwm tseem ceeb rau PVD yog hyperlipidemia, haus luam yeeb, ntshav qab zib mellitus thiab hyperviscosity. Lwm yam ua rau tuaj yeem yog vascular o, mob autoimmune ntawm vascular system, coagulopathies thiab phais.
History
Qhov kev kho mob tseem ceeb ntawm PVD yog qhov sib cuam tshuam claudication. Qhov chaw ntawm qhov mob cuam tshuam nrog qhov chaw ntawm cov hlab ntsha occluded. Piv txwv li, tus kab mob aortoiliac ua rau mob ntawm tus ncej puab thiab pob tw. Koj tuaj yeem tau txais cov lus qhia txog PVD los ntawm cov neeg mob cov tshuaj. Cov neeg mob PVD tshwj xeeb tau muab tshuaj nrog pentoxyfyllin. Aspirin feem ntau yog siv rau CAD, uas qhia txog PVD.
Symptoms
Cov cim qhia ntawm PVD suav nrog 5 P's: pulselessness, tuag tes tuag taw, paresthesia, mob, thiab pallor.
Daim tawv nqaij hloov pauv xws li alopecia, cov xim pigmentation ntev, cov rau tes nkig thiab qhuav, liab, tawv nqaij tawv tuaj yeem pom.
Ntev ntev PVD tuaj yeem ua rau loog, tuag tes tuag taw, thiab cyanosis ntawm cov extremities. Limbs yuav txias, thiab gangrene tuaj yeem tsim. PVD yuav tsum tau xav tias yog tus neeg mob muaj qhov mob uas tsis zoo mus ntev.
Diagnosis
Kev kuaj ntshav hauv qab xws li Cov Ntshav Tag Nrho, Ntshav urea nitrogen, Creatinine, thiab kev tshawb fawb electrolyte tuaj yeem ua tiav. D-dimer thiab C-reactive proteins tuaj yeem kuaj xyuas cov tsos mob ntawm qhov mob. Tus qauv ntsuas los kuaj xyuas qhov cuam tshuam ntawm intraluminal yog arteriography, tab sis nws muaj kev pheej hmoo thiab tsis muaj nyob rau thaum muaj xwm txheej ceev. Kev ntws los ntawm lub nkoj tuaj yeem txiav txim siab los ntawm Doppler ultrasonography. CT thiab MRI tuaj yeem ua tau los ntsuas PVD. Lub pob luj taws brachial plexus index yog ib qho kev sim siv niaj hnub uas sib piv cov ceg qis qis nrog lub siab ceg siab.
Kev tswj hwm
tshuaj tiv thaiv kab mob thiab statins tuaj yeem noj. Thaum muaj xwm txheej ceev, heparin tuaj yeem muab tso rau hauv cov hlab ntsha. Intra-arterial thrombolytics tuaj yeem siv thaum tsis muaj los ntshav.
Kev cuam tshuam phais yog lwm txoj hauv kev kho PVD. Lub forgarty catheter tuaj yeem siv los tshem tawm emboli. Percutaneous transluminal coronary angioplasty tuaj yeem siv los kho cov hlab ntsha stenosed.
PAD yog dab tsi?
Nyob rau hauv PAD, kev loj hlob ntawm atherosclerotic plaques tshwm sim nyob rau hauv cov phab ntsa ntawm cov hlab ntsha feem ntau nyob rau hauv ceg, plab hnyuv, thiab ob lub raum. Qhov no ua rau txo cov ntaub so ntswg perfusion. Yog tias tsis kho raws sijhawm, nws tuaj yeem ua rau muaj kab mob anaerobic superimposed, thiab qhov mob no tuaj yeem ua rau muaj kab mob gangrene. Cov ntaub so ntswg gangrenous yog xim dub, xim av lossis xiav tsaus thiab tig mus rau hauv cov tawv nqaij tawv nrog lub sijhawm. Qhov mob maj mam txo qis nrog kev tuag ischemic ntawm nociceptors thiab paj hlwb hauv cheeb tsam cuam tshuam. Amputation feem ntau yog ua tiav yog tias qhov xwm txheej tau hnyav zuj zus mus rau qib no.
Daim duab 02: PAD
Symptoms
Cov tsos mob ntawm qhov tsis txaus ntseeg hauv qhov kawg tuaj yeem suav nrog hnyav, sib cuam tshuam claudication, cramping, thiab qaug zog. Cov tsos mob ntawm kev txo qis perfusion rau ob lub raum muaj xws li ntshav siab, thiab txo qis perfusion tuaj yeem ua rau lub raum tsis ua haujlwm.
Diagnosis
Zoo ib yam li PVD, PAD kuj tuaj yeem kuaj tau nrog qhov kev sim yooj yim, ABI (Ankle brachial index). Lwm qhov kev tshawb nrhiav muaj txiaj ntsig suav nrog
- Y Doppler Ultrasonography
- Magnetic resonance angiography (MRA)
- CT angiography
- catheter raws angiography Management:
Kev tswj hwm
Kev hloov pauv lub neej hauv qab no ua lub luag haujlwm tseem ceeb hauv kev tswj hwm PAD
- Kev haus luam yeeb
- Kev tswj ntshav qab zib kom raug
- Kev noj zaub mov kom zoo nrog cov rog tsawg thiab cov rog trans
- tswj ntshav siab kom raug
- koom nrog kev tawm dag zog ib txwm
Cov tshuaj siv los kho PAD suav nrog cov tshuaj tiv thaiv kab mob, statins, thiab tshuaj tiv thaiv ntshav siab. Kev phais mob xws li angioplasty thiab bypass phais yog xav tau rau cov neeg mob, uas tsis tau txo qis los ntawm kev hloov pauv kev ua neej thiab tshuaj.
Qhov Zoo sib xws ntawm PVD thiab PAD yog dab tsi?
- Ob leeg tshwm sim vim kev hloov pauv ntawm cov phab ntsa vascular.
- Pulselessness, tuag tes tuag taw, paresthesia, mob, thiab pallor tuaj yeem pom hauv ob qho xwm txheej.
- Yuav kuaj tau nrog ABI.
- Yuav kho tau nrog statins, tshuaj antiplatelet, thiab antihypertensives.
- Kev hloov pauv kev ua neej tuaj yeem tiv thaiv kev kis kab mob.

Summary – PVD vs PAD
Ob leeg PVD (kab mob peripheral vascular) thiab PAD ((kab mob peripheral arterial) tshwm sim vim muaj kev hloov pauv ntawm phab ntsa vascular. PAD yog ib pawg ntawm PVD. ob leeg hlab ntsha thiab cov hlab ntsha whereas PAD, raws li nws lub npe qhia, tsuas yog tshwm sim hauv cov hlab ntsha.
