A-V FISTULA CREATION BY NOW IS A STANDARD PROCEDURE FOLLOWED WORLDWIDE FOR HEAMODILYSIS ACCESS IN CKD PATIENTS.THERE ARE
TIMES WHEN HEAMODIALYSIS BECOMES A CHALLENGE BECAUSE OF NON AVAILABILITY OF VENOUS ACCESS.THE REASONS BEING IN PLENTY LIKE THROMBOSED SUPERFICIAL VEINS,FAILED A-V ACCESS EARLIER SO ON AND SO FORTH .ROUTINELY AN AV FISTULA IS CREATED ON THE FOREARM BETWEEN THE RADIAL ARTERY AND CEPHALIC VEIN FOR VENOUS ACCESS.THE DIALYSIS THROUGH THESE ARTERIALISED VEINS CAN BE STARTED ONCE THE FISTULA MATURES.SOMETIMES THE VASCULAR SURGEON NEEDS TO USE THE BRACHIAL ARTERY TO DIRECT BLOOD INTO THE VEINS FOR FUTURE HEAMODIALYSIS ACCESS.THESE ARE THE ROUTINE SURGERIES DONE FOR CKD PATIENTS FOR DIALYSIS.CERTAIN SITUATIONS DEMAND THE USE OF SYNTHETIC GRAFT FOR HEAMODIALYSIS. VASCULAR SURGEONS WORLDWIDE HAVE THEREFORE COME UP WITH FEMORO-FEMORAL AV FISTULAS WITH PTFE GRATS,BRACHIO- AXILLARY FISTULAS,AXILLO-AXILLARY FISTULAS AND RADIO-CEPHALIC FISTULAS WITH PTFE GRAFTS.THE PATENCY OF NATIVE VESSEL FISTULAS IS CERTAINLY BETTER THAN THE ONES WHEREIN SYNTHETIC GRAFT IS USED BUT THEN THESE GRAFTS ARE USED IN UNAVOIDABLE AND DESPERATE CIRCUMSTANCES LIKE SMALL VEINS,FAILED NATIVE FISTULAS IN THE PAST SO ON AND SO FORTH.ITS AN IMPORTANT WEAPON IN THE ARMEMTARIUM OF THE VASCULAR SURGEON AS IT MAKES THE LIFE OF THE CRF PATIENT RELATIVELY EASY AND IS WORTH THE EFFORT.PTFE IS THE SYNTHETIC GRAFT GENERALLY USED FOR MAKING THESE FISTULAS. WE REPRESENT AN UNUSUAL CASE WHEREIN AN AXILLO-FEMORAL A-V FISTULA WAS CREATED CONNECTING THE LEFT AXILLARY ARTERY WITH THE LEFT COMMON FEMORAL VEIN WITH A 6 MM PTFE SYNTHETIC GRAFT AND TUNNELING IT UNDER THE SKIN FOR VENOUS ACCESS.
THIS PATIENT AGED 55 YEARS MET WITH AN ACCIDENT SOME TWO YEARS AGO .SHE ENDED UP LOSING HER LEFT LOWER LIMB AND BOTH HER KIDNEYS FAILEDAND IS ON REGULAR DIALYSIS.SHE HAD AN AV FISTULA MADE ON HER LEFT FOREARM IN THE PAST CONNECTING THE BRACHIAL ARTERY AND CEPHALIC VEIN ONLY TO BE CLOSED LATER AS SHE DEVELOPED MASSIVE SWELLING OF HER LEFT UPPER LIMB AFTER FISTULA CREATION. FISTULOGRAM WAS DONE AND IT SHOWED SHE HAD SUPERIOR VENA CAVA SYNDROME.THE PROBABLE CAUSE OF HER SVC SYNDROME SEEMED TO BE IATROGENIC AS HER INTERNAL JUGULAR VEIN WAS CANNULATED EARLIER FOR DIALYSIS.WE HAD LIMITED OPTIONS IN HER AS FISTULA COULD NOT BE CREATED IN THE OTHER UPPER LIMB BECAUSE OF SVC SYNDROME.THE ONLY USUAL OPTION LEFT IN SUCH A SCENARIO WAS TO CREATE AN AV FITULA WITH GRAFT ON HER RIGHT THIGH CONNECTING THE FEMORAL VEIN WITH THE FEMORAL ARTERY AS SHE HAD AN AMPUTATED LEFT LEG(HIGH ABOVE KNEE AMPUTATION).SINCE SHE STILL HAS AN ACTIVE LIFESTYLE MAKING AN AV FISTULA ON THE UNAFFECTED RIGHT LEG WAS NOT THE BEST OPTION BECAUSE OF FEAR OF SYNTHETIC GRAFT INFECTIONS AND WOUND COMPLICATIONS THAT MAY HAVE JEOPARDISED THE VIABILITY OF HER RIGHT LOWER LIMB IN NEAR FUTURE.
TO DATE THIS IS THE FIRST OF ITS KIND AV FISTULA CREATED IN
THE IDEA OF REPORTING THIS ARTICLE IS TO GIVE HOPE TO THOUSANDS OF PEOPLE AROUND SUFFERING FROM CRF WHEREIN VENOUS ACCESS FOR HEAMODIALYSIS IS UNAVAILABLE FOR MYRIAD REASONS. FISTULA FOR HEAMODIALYSIS CAN ALMOST ALWAYS BE CREATED EVEN IN SEEMINGLY DIFFICULT SITUATIONS.
WELL THE ANSWERS TOU YOUR QUESTIONS ARE MORE OR LESS IN THE POSTED BLOG ITSELF.STILL AS PER YOUR QUERIES I WOULD LIKE TO SAY THE LENGTH OF THE GRAFT IS AROUND 60CMS,NO NEED TO RESTRICT ARM MOVEMENTS AND YES THE PLANE OF THE GRAFT TO AN EXTENT IS SUPERFICIAL FOR VENOUS ACCESS.YOU GET A GOOD 20CMS OF GRAFT TO PUNTURE FOR DIALYSIS.
