Taksa sir lam kawngpui thup: Natural bypass system (Collateral Circulation) chungchang zir rawh

I kalna kawngpui lian takah chuan lirthei tlan tam tak a awm a, kawngpui chu a inkhar vek tawh ang tih han ngaihtuah teh. Chuti a nih chuan engtin nge i tih? A tam zawkah chuan chu lai hmun hre chiang tak emaw Google Maps en emaw kan zawt a, kan kalna tur hmun thleng tur chuan kawngpui sir te tak te kan zawh a, kan tlu lut lo a ni lawm ni? Mak tak maiin hei hi kan taksa chhunga thil thleng dik tak chu a ni. Kan taksaa thisen kalna lian tak, chu chu thisen kalna kawng eng emaw vanga a inkharkhip a nih chuan, taksain ‘side roads’ system a siam a, chu chu vawiinah hian he thuziak-ah hian kan sawi dawn a ni.

A awlsam zawngin, collateral circulation chu eng nge ni?

A hming hi a buaithlak deuhin a lang thei a, mahse a takah chuan a awlsam khawp mai. Collateral Circulation chu kan taksaa thisen kalna kawng lian tak (artery emaw vein emaw) a block emaw a chhiat emaw chuan thisen phur tur thisen kalna kawng dang, emaw "backup" system siam a ni.

A awlsam zawngin, hei hi kan taksa pianphung ‘bypass’ system a ni . A hmaa ka sawi tawh ang khan main road a inkhar chuan side road kan zawng a, taksa pawhin thisen kalna tur side road thar a siam bawk. Hei hi kan taksaa defense mechanism mak tak a ni.

He natural bypass system hian engtin nge hna a thawh?

Tunah chuan, "Chuti a nih chuan heng side road te hi siam nghal a ni em?" Dik tak chuan hei hi kawng hnih in a thleng thei.

1. Thisen kalna kawng te tak te awmsa tihzauh: Kan taksa hian thisen kalna kawng te tak te, a tlangpuiin hman loh, kan thisen kalna bulpui nena inzawm, network a nei a. Main vessel pakhat a block tan chuan taksa chuan he dinhmun hi a hre chiang hle. Tichuan, thluak leh taksa chhunga system hrang hrang atanga signal lo lutte a\angin chu thisen kalna kawng te te chu zawi zawiin a lianin a zau chho tan ta a ni. Tichuan, thisen chu main vessel kal tlang thei lo chu heng side road zau thar siamah hian a kal tan ta a ni.

2. Thisen kalna kawng thar siam: A chang chuan, a bik takin thisen kalna lian tak chu zawi zawiin a inkharkhip chuan taksain thisen kalna kawng thar a siam tan thin. Damdawi lamah chuan he thil hi angiogenesis tiin kan sawi thin. Taksa chuan taksa peng pakhata thisen kal zat chu a tlahniam tih a hre chiang hle. Chutih lai chuan chu organ ngei chuan chemical signal a tichhuak a, "Thisen kan nei tlem a, kawngpui thar siam rawh," a ti a ni. Chumi ang chuan heng thisen kalna kawng tharte hi a lo piang ta a ni.

Mi zawng zawng hian kan taksaah hian heng thisen kalna extra te hi kan nei vek em?

Ni e, kan piang vek a, collateral blood vessel system engemaw zat neiin kan piang vek a ni. Mahse , mi tin taksaa heng vessel awm zat leh an lian zawng hi mi hrang hrangah a inang lo thei . Thil tam takah a innghat a, chung zingah chuan genetics leh nunphung pawh a tel.

Heng extra blood vessels te hi chi thum ah a awm thei.

Eng natna chi hrang hrangah nge he collateral circulation hi a pawimawh?

He natural bypass system hian thisen kalna kawng tikhawlo thei dinhmun eng pawhah min pui thei a ni. Hei hi a hnuaia natna nei tan chuan a pawimawh hle:

• Atherosclerosis: Hei hi thisen kalna kawngkhar a thau leh cholesterol tam lutuk avanga thisen kalna kawng (arteries) a khauh (hardening) a ni. Tui pipe chhunga rust lo awm ang mai a ni. Artery chu zawi zawiin a block chhoh zel chuan taksa hian collateral arteries siam hun a nei ta a ni.
• Coronary Artery Disease: Thinlung thisen petu thisen kalna kawng (arteries) a block. Hei hi heart attack thlentu ber a ni. Collateral system tha tak nei mi pakhatin heart attack nei mahse, a chhiatna chu eng emaw chen chu a tlahniam thei a ni.
• Ischemic Stroke: Thluaka thisen petu thisen kalna kawng (artery) a inkharkhip avanga stroke awm.
• Peripheral Artery Disease (PAD): Thisen petu thisen kalna kawngte a tawi a, a bik takin keah a awm. Hei hian kea kal laiin ke a ti na thei a ni.

Heng thisen kalna extra te hian heng natna avanga lo awm ischemia , emaw, taksa peng pakhata thisen supply tlahniam emaw chu a titawp vek thei lo. A châng chuan main vessel chu a block nghal a nih chuan extra vascular system hian thisen a supply rang thei lo mai thei.

Chuvangin, hetiang dinhmun hi i neih chuan, i doctor hmu ngei tur a ni a, enkawlna dik tak i la tur a ni , he natural system chauh rinchhan ai chuan. Hei hi nunna leh thihna inthlauhna a ni thei.

He extra vascular system hi eng chen nge a awm?

Collateral circulation a lo awm tawh chuan, chu thisen kalna kawng lian zawkte chuan taksaa thisen kal dan pangngai chu thla tam tak, kum tam tak chhung pawh a awm reng theih nan a pui thei a ni.

Mahse, kan tar chhoh zel chuan heng thisen kalna kawng tam zawk hi a lo tlem zauh zauh a, a nih loh leh a lianin a lo tlem tan ta a ni. Hei hi rarefaction kan ti a ni . Hetiang dinhmun hi a bik takin rilru lam natna nei tan chuan a lo awm rang thei hle. Chutianga thisen kalna kawng dang (extra blood vessels) a lo tlem chuan, main vessel thar a inkhar a nih chuan an puih theihna pawh a tlahniam bawk. Chuvang chuan kum upa lam leh natna dang kan neih chhoh zel chuan kan hriselna hi kan enkawl nasa zawk tur a ni an ti.

He system hi taksa peng hrang hrangah nge a awm?

He collateral circulatory system hi kan taksa peng hrang hrangah a awm a. He venhimna system hi thisen kalna kawngkhar a inkharkhip theihna hmun apiangah hmuh theih a ni.

A tawi zawngin, collateral circulation hi kan taksain thisen kalna kawngkhar block a do theihna mak tak a ni. Heart attack emaw stroke emaw avanga chhiatna thleng thei tur venna tur foolproof way a ni lo. Mahse, ṭhenkhatah chuan hmanraw hlu tak, nunna chhanhimtu a ni thei.

Tunah hian medical researcher-te chuan artificial collateral blood vessel siam a, damlote hnena transplant theih dan tur an zirchiang mek a ni. He zirchianna hi a hlawhtlin chuan nakin lawkah thisen kalna kawng natna vei mi tam tak tan hahdamna nasa tak a pe thei ang.
