Amaz­ing Stent Us­age In Coro­nary An­gio­plasty And Other Pro­ce­dures

The Miracle - - Health -­­nol­ogy-health

Coro­nary an­gio­plasty, also known as per­cu­ta­neous coro­nary in­ter­ven­tion, is a sur­gi­cal pro­ce­dure that in­volves adding and in­flat­ing a tem­po­rary bal­loon into a clogged artery to widen it. In most cases, coro­nary an­gio­plasty is com­bined with the per­ma­nent place­ment of a stent, which is a small, mesh wire tube de­signed to prop the artery open, so it does not close again. Com­pared to other car­diac surg­eries, coro­nary an­gio­plasty pa­tients have a short re­cov­ery time and ex­pe­ri­ence less pain. Here are some other ways stents are used.

7. Open Blocked Artery Dur­ing Heart At­tack

Stents are most com­monly used dur­ing coro­nary an­gio­plasty to widen a blocked artery and al­low blood and oxy­gen to flow to the heart. Stents re­lieve symp­toms of short­ness of breath and chest pain by prop­ping open the blocked artery. They can also be used dur­ing a heart at­tack to re­duce the amount of dam­age done to the heart. A tiny bal­loon is first in­serted into the blocked artery and in­flated. Then the bal­loon is re­moved, and a stent is per­ma­nently placed.

6. Pro­mote Skin Heal­ing Af­ter A Skin Graft

A skin graft is a sur­gi­cal pro­ce­dure used to re­pair skin that has been ex­ten­sively burned or wounded by trans­plant­ing healthy skin taken from other ar­eas of the body. Re­search sup­ports us­ing stents to pro­mote the growth of healthy skin af­ter a skin graft by widen­ing blood ves­sels around the af­fected area to en­cour­age blood and oxy­gen flow, which is cru­cial for re­pair­ing the skin. In some cases, stents are made from rub­ber foam pads and sta­pled over the skin graft.

5. Esophageal Stent

Esophageal can­cers af­fect­ing the throat can make it hard for the af­fected per­son to swal­low. Esophageal stents are flex­i­ble, mesh tubes mea­sur­ing three-quar­ter of an inch wide that are placed in the throat of pa­tients with esophageal can­cer to prop the throat open and al­low for eas­ier swal­low­ing. Esophageal stents are also used to treat fis­tu­las, per­fo­ra­tions, leaks and stric­tures of the esoph­a­gus. One study in­di­cated that thir­tytwo per­cent of pa­tients re­ported com­pli­ca­tions such as pro­longed chest pain, stent mi­gra­tion, and bleed­ing.

4. Brain Stents

Brain aneurysms oc­cur when there is a weak or bulging area lo­cated in an artery wall of a blood ves­sel sup­ply­ing blood flow to the brain. Most of the time, no symp­toms are present. Dur­ing rare cases, the brain aneurysm rup­tures and floods the skull with blood, caus­ing a stroke. Brain stents are used in the blood ves­sels of peo­ple with a high risk of a brain aneurysm to strength blood ves­sels and sup­port blood and oxy­gen flow to the brain.

3. Bil­iary Metal Stent

Bil­iary metal stents, also known as a bile duct stent, are use­ful for treat­ing sev­eral com­pli­ca­tions of bile duct dis­or­ders. They have been shown to al­le­vi­ate jaun­dice due to ad­vanced bile duct can­cer, drain ex­cess bile, and open blocked ar­ter­ies that are com­mon in cases of bile duct can­cer. Bil­iary metal stents may also re­duce pain as­so­ci­ated with pan­cre­ati­tis. They are com­monly used in gall­blad­der surgery to sup­port sur­round­ing blood ves­sels and de­crease the risk of block­age.

2. Tracheal Or Bronchial Stent

Around thirty per­cent of lung can­cer pa- tients will de­velop a cen­tral air­way ob­struc­tion. Bronchial and tracheal stents can be used to open the blood ves­sels con­nected to the lungs to im­prove breath­ing. They may be used to re­lieve com­pli­ca­tions as­so­ci­ated with steno­sis and anas­to­mo­sis af­ter a lung trans­plant. Stents are made of sil­i­con or metal and can be placed in ei­ther the bronchi or tra­chea de­pend­ing on where a nar­row blood ves­sel ex­ists.

1. Ureteral Stent

A ureteral stent, oth­er­wise known as a ure-teric stent, is de­signed to widen the tubes that carry urine to the blad­der from the kid­neys. They are thin tubes in­serted into the ureter to pre­vent ob­struc­tion or pre­vent nar­row­ing of the ves­sels, which would oth­er­wise re­strict urine flow. Al­though the length of the stent may vary, most are around twen­ty­four to thirty cen­time­ters long. Ureteral stents help in­crease the flow of urine from the blad­der and re­store kid­neys to their op­ti­mal func­tion­ing.
