Angioplasty Gangrene Se Pair Kaise Bachati Hai — Step-by-Step Samjhiye

Gangrene ka ilaaj ek sui aur chhote balloon se — sunne mein ajeeb lagta hai, lekin yeh ab routine interventional radiology hai. Yahan poora process step-by-step samjhaya gaya hai.

Artery Kholna Kyun Sabse Zaroori Hai

Vascular gangrene ka matlab hai tissue ka marna kyunki khoon ki supply kaafi nahi hai. Pair ki artery atherosclerotic plaque — cholesterol aur calcium ke jame — ki wajah se tang ya band ho gayi hai. Body apne aap yeh plaque nahi hataa sakti. Angioplasty physically plaque ko dabaake channel ko chaudaa karti hai aur blood flow restore karti hai.

Procedure — Step by Step

1. Taiyaari: Patient procedure table par leta hai. Access site par — usually groin artery (femoral artery) ya kabhi seedha pair ki artery par (neeche ke disease ke liye) — local anaesthesia ka injection diya jaata hai. General anaesthesia ki zarurat nahi hoti.
2. Access: Ultrasound guidance se ek sui artery mein lagayi jaati hai — lagbhag pen ki nok jitni. Ek patli plastic sheath (introducer) sui ke through lagayi jaati hai taaki stable access mile.
3. Angiogram: Contrast dye inject karke X-ray images li jaati hain — yeh arteries ka real-time naqsha banata hai. Dikhta hai ki blockage kahan hai, kitni lambi hai, aur kaun si nasen involved hain.
4. Blockage paar karna: Ek bahut patli guidewire (0.018 se 0.035 inches) X-ray guidance mein blocked hisse se guzaari jaati hai. Yeh aksar sabse mushkil step hota hai — khaas taur par complete occlusions mein. Dr. Rohit Agarwal specialised wires aur techniques use karte hain jismein subintimal angioplasty bhi shamil hai lambi, complex blockages ke liye.
5. Balloon angioplasty: Ek catheter jiske tip par chhota balloon hai, wire ke upar blockage tak le jaaya jaata hai. Balloon ko high pressure (4-16 atmospheres) par 30-120 seconds ke liye inflate kiya jaata hai — yeh plaque ko dabaake aur todke lumen ko chaudaa karta hai.
6. Drug-coated balloon: Jahan dobara tang hone ka risk hai (khaas taur par ghutne ke neeche ki nasen), paclitaxel coated drug-coated balloon use hota hai. Dawai scar tissue response ko rokti hai jo artery ko dobara tang karti hai.
7. Stenting (agar zarurat ho): Agar artery waapas sikudti hai ya significant dissection hota hai, toh metallic stent lagaya jaata hai jo artery ko permanently khula rakhta hai. Specific locations par drug-eluting stents use hote hain.
8. Completion angiogram: Final images confirm karte hain ki blood flow pair tak poora restore ho gaya hai. Zyaadatar patients ko table par hi pair garam hota mehsoos hota hai aur dard kam hone lagta hai.
9. Closure: Access sheath nikaal kar puncture site ko closure device ya manual pressure se seal kiya jaata hai. Koi tankaa nahi. Sirf ek chhoti si patti lagti hai.

Angioplasty Ke Baad Gangrene Ka Kya Hota Hai?

Blood flow restore hone ke baad tissue marne ki process ruk jaati hai. Gangrenous area ke kinaaron par viable tissue recover hona shuru hota hai. Pehle se maujood zaakhm aur ulcers ko ab oxygen aur nutrients milte hain aur woh bharna shuru ho jaate hain. Aane wale hafton mein demarcated dead tissue apne aap alag ho sakta hai. Wound care saath mein chalta rehta hai. Bahut se cases mein sirf pehle se mara hua tissue nikalna padta hai — baaki poora pair bach jaata hai.
