Factors affecting patency of arteriovenous fistula following first percutaneous transluminal angioplasty

ConclusionIn conclusion, higher AAC grade and anatomic factor related to the location of AVF (upper arm) were the important predictors of AVF dysfunction after PTA. These results could assist in tailoring surveillance programs and performing appropriate interventions for risky AVF.

Paclitaxel-coated balloons and paclitaxel-eluting stents caused quite the stir for manufacturers and physicians this year, but an FDA approval this week marks a major step forward for this category of devices. The agency approved Medtronic's IN.PACT AV drug-coated balloon for the treatment of failing arteriovenous access in patients with end-stage renal disease (ESRD) undergoing dialysis. AV fistulae are created and used to enable hemodialysis for patients with ESRD. Over time, vessel restenosis limits the ability to use AV fistulae effectively. In order to restore function, patients often undergo one to three ...

CONCLUSION: Our technique of retrieval may be suitable for cases of balloon rupture with a circumferential tear during percutaneous transluminal angioplasty. The technique enables less invasive retrieval and continuation of the percutaneous transluminal angioplasty thereafter. PMID: 31434523 [PubMed - as supplied by publisher]

CONCLUSION: Our results indicate that DCB angioplasty is associated with significantly improved patency in the treatment of restenosis in radiocephalic AVFs. A longer follow-up or randomized controlled trial is warranted. PMID: 30897933 [PubMed - as supplied by publisher]

ConclusionsThe results demonstrate safety of the study balloon in treating AV access stenosis. Nominal-diameter angioplasty was achieved at relatively low pressure in most study patients without the use of adjunctive procedures, and resumption of normal dialysis was achieved for all patients.
