Av fistula complications

Hideyuki Hasebe, Akira Takanohashi, Kazuaki Shirota, Hajime Nakamura
Atrioventricular (AV) block and pseudoaneurysm of the mitral-aortic intervalvular fibrosa (P-MAIVF) are rare complications of infective endocarditis (IE). A 72-year-old man with severe aortic stenosis was hospitalized due to IE. After admission, intermittent AV block and P-MAIVF were noted. Interestingly, an accelerated junctional rhythm was observed during the process of AV block resolution. Elective surgery, which included patch closure of the fistula and replacement of the aortic valve, was successfully performed...

As a consequence of the central role of the arteriovenous fistula for dialysis (AVF) in the clinical management of the dialysis patient the necessity to limit the puncture-related complications to extend as much as possible the life of the vascular access. Accordingly, the AVF needling technique has gained growing attention. Alongside the traditional rope ladder (RL) puncture method, the buttonhole technique (BH) is increasingly popular; this technique employs the same cannulation sites of AVF in every dialysis associated with the use of dull needles to minimize vessels damage...

Nosocomial catheter-related and Arteriovenous fistula (AV)-related infections are significant concern in patients undergoing haemodialysis. These infections are associated with multiple complications as well as mortality and demands immediate and appropriate management. While coagulase-negative staphylococci, S.aureus, and Escherichia coli are the most common causes of catheter-related infections in haemodialysis patients, such infections caused by Pseudomonas aeruginosa are relatively rare. Here, we present an unusual case of 36-year-old male patient with chronic renal failure, who developed endocarditis and sepsis from Pseudomonas aeruginosa infection of the left hand arteriovenous fistula...

OBJECTIVES: Right heart catheterization is an important diagnostic tool but carries risks of adverse events. Little is known about the feasibility and safety of using dialysis arteriovenous (AV) shunts. We aim to evaluate the feasibility and safety of using dialysis AV shunts for access in right heart catheterization. METHODS: Hemodialysis patients who required right heart catheterization were prospectively enrolled. A 7 Fr sheath was inserted and a balloon-tipped pulmonary artery catheter was advanced for right heart catheterization...

BACKGROUND: Traumatic axilloaxillary arteriovenous (AV) fistulas are rare occurrences, with the predominance of AV fistulas in this region occurring as an alternative surgical intervention in patients who are undergoing hemodialysis. CASE REPORT: We describe the case of a young man with this condition caused by a previous penetrating trauma who had a delayed diagnosis primarily because of the infrequency of the clinical presentation. This is one of a few documented cases of axilloaxillary AV fistulas in the setting of trauma...

BACKGROUND & OBJECTIVES: Access monitoring and pre-emptive angioplasty is known to decrease the incidence of AVF/AVG thrombosis. The effect on increase the longevity and functionality of Arterial-Venous access (AV access) in end-stage renal disease (ESRD) patients is not settled. Thrombosis is the leading cause of vascular access complications and is almost always associated with the presence of stenosis. Percutaneous transluminal angioplasty (PTA) is an accepted treatment of stenotic lesions in AV access (NKF 2001)...

The major puncture-site complications of the transfemoral approach are retroperitoneal bleeding (RPB), arteriovenous (AV) fistula, and arterial pseudoaneurysm. Although the management of RPB and AV fistula depends on individual cases, our experience shows that the use of a covered stent with intravascular ultrasound (IVUS) guidance can successfully manage percutaneous coronary intervention-associated RPB and AV fistula. IVUS guidance can therefore make it easy to use an optimal-size covered stent.

BACKGROUND: The Venous Window Needle Guide (VWING; Vital Access Corp, Salt Lake City, Utah) is a surgically implanted titanium device designed to facilitate cannulation of uncannulatable dialysis access arteriovenous fistulas (AVFs) because of excessive depth, aneurysm formation, or tortuosity but that exhibit sufficient flow volume to support hemodialysis. We report the 18-month fistula patency, functionality, and complications of the use of the VWING device. METHODS: This retrospective study examined AVF patency, VWING functionality, interventions, and device infections at 18 months after VWING implantation...

Pial arteriovenous fistulae (AVF) are rare vascular lesions comprising single or multiple arterial feeders draining directly into the venous channel without intervening tangle of blood vessels as in brain AV malformations. In our present paper, we describe three cases of pial AVF in the pediatric age group with different presentations treated successfully with endovascular and surgical methods. Two patients underwent treatment for pial AVF by the endovascular technique and one by surgical clipping. The treatments were successful with good clinical outcome...

Renal arteriovenous (AV) shunt, a rare pathologic condition, is divided into two categories, traumatic and nontraumatic, and can cause massive hematuria, retroperitoneal hemorrhage, pain, and high-output heart failure. Although transcatheter embolization is a less-invasive and effective treatment option, it has a potential risk of complications, including renal infarction and pulmonary embolism, and a potential risk of recanalization. The successful embolization of renal AV shunt requires a complete occlusion of the shunted vessel while preventing the migration of embolic materials and preserving normal renal arterial branches, which depends on the selection of adequate techniques and embolic materials for individual cases, based on the etiology and imaging angioarchitecture of the renal AV shunts...

BACKGROUND: Native or prosthetic arteriovenous (AV) fistulas are preferred for permanent haemodialysis (HD) access. These are marked with circuit steno-occlusive disease leading to dysfunction or even failure. Late failure rates have been reported as high as 50%. Standard angioplasty balloons are an established percutaneous intervention for HD access stenosis. Reported restenosis rates remain high and practice guidelines recommend a wide 6-month primary patency (PP) of at least 50% for any intervention...

Intravenous drug abusers commonly develop endocarditis due to injection of particulate matter that can cause endothelial damage to the valves. The frequent need to access the venous system can result in vascular traumas with potential complications including arteriovenous (AV) fistulas. Here, we present the case of an intravenous drug abuser with endocarditis and an unusually large AV fistula in the groin. The patient was successfully operated for endocarditis. However, the AV fistula was at the time not acknowledged...

BACKGROUND: Hemodialysis (HD) in children with a concomitant ventriculoperitoneal shunt (VPS) is rare. Registry data suggest that peritoneal dialysis with a VPS is safe, but little is known about HD in the presence of a VPS. METHODS: We performed a 10-year survey to determine the prevalence of a VPS, complications and outcome in children with a VPS on HD in 15 dialysis units from the 13 countries participating in the European Pediatric Dialysis Working Group. RESULTS: Eleven cases of HD with a VPS were reported (prevalence 1...

Spinal dural arteriovenous fistula (SDAVF) is the most common spinal vascular malformation, however it is still rare and underdiagnosed. Magnetic resonance imaging findings such as spinal cord edema and dilated and tortuous perimedullary veins play a pivotal role in the confirmation of the diagnosis. However, spinal angiography remains the gold standard in the diagnosis of SDAVF. Classic angiographic findings of SDAVF are early filling of radicular veins, delayed venous return, and an extensive network of dilated perimedullary venous plexus...

The authors describe herein the use of balloon-distensible stent grafts for endovascular treatment of patients presenting with traumatic arteriovenous fistulas in the first segment of the vertebral artery, exemplified by two clinical case reports. In both cases, the arteriovenous fistula formed after a stab-and-slash wound in the neck area. In order to exclude the arteriovenous aneurysm from the blood flow in the first case we performed endoprosthetic repair of the first segment of the subclavian artery with shutting off of the ostium of the vertebral artery carrying the aneurysm...

Vascular complications arise in uremic patients in the absence of clinically significant atherosclerotic disease. Elevated serum parathyroid hormone (PTH) and abnormal calcium (Ca) and phosphorus (P) balance have been implicated in vascular damage in chronic kidney disease (CKD) patients, but there is lack of histo-pathological studies. Patients with CKD stage 5 and 5D who underwent arterio-venous fistula were included in this study. Baseline and laboratory parameters including assessment of total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, uric acid, albumin, calcium, phosphorus, intact PTH (iPTH) and vitamin D level were documented...
