Improved quality of surgical procedures can minimize complications, the morbidity and mortality of patients, and in addition decrease costs. Quality indicators in angioaccess surgery are, however, ...not clearly defined. The aim of this review article is therefore to find the most important factors affecting quality in vascular access procedures. Even though autogenous arteriovenous fistula has been recognized as the best vascular access for hemodialysis, the high percentage of unsuccessful attempts associated with it raises the question about quality assessment in angioaccess procedures. Unfortunately, quality indicators in vascular access surgery are difficult to define and measure. Among those that can be obtained are: the time between the presentation of patients to a vascular access surgeon and the construction of a fistula, the percentage of autogenous fistulas, the percentage of functional fistulas in prevalent and incident hemodialysis patients, the percentage of creation of a functional fistula in the first attempt, and durability of an access. Organizational improvement and educational programs are also necessary at institutions with inferior quality indicators of vascular access care, as even small increase in quality may mean the survival of an individual patient. Quality indicators in angioaccess surgery can also serve as a helpful tool in choosing the best vascular access surgeon or vascular access center. The choice can consequently reflect on increased survival and quality of life in patients needing hemodialysis.
rarely causes gastrointestinal diseases but shows an affinity for the endovascular epithelium.
We describe a case of
bacteremia related to vascular prosthesis and pseudoaneurysm infection, with a ...review of the literature.
A 67-year-old male was admitted with a history of fever, weakness and painful swelling of the groin. After unsuccessful treatment with ciprofloxacin, the patient was transferred to our hospital, where he had been previously treated for aortoiliac occlusive disease including a prosthetic aortobifemoral and popliteal bypass with polyester graft placement. An angiography showed a pseudoaneurysm in the groin and, therefore, repair of the pseudoaneurysm, removal of the prosthesis and biologic graft placement were performed. Blood cultures and tissue samples of the vascular prosthesis and pseudoaneurysm yielded
resistant to ciprofloxacin. The patient was treated with meropenem for four weeks, followed by amoxicillin-clavulanate for another two weeks after discharge. Eight previously published cases of
bacteremia due to infected cardiovascular prosthetic devices (prosthetic heart valves, implantable cardioverter-defibrillators and a permanent pacemaker) were summarized in the review.
To our knowledge, this is the first report of a
bacteremia related to post-surgical infection of a vascular prosthesis causing a pseudoaneurysm.
U Kliničkoj bolnici Dubrava u Zagrebu prvi je put u Hrvatskoj ugrađen novi sustav za krvožilni pristup kod bolesnika koji se liječi kroničnom hemodijalizom. Radi se o kombinaciji centralnoga venskog ...katetera i grafta engleskog naziva Hemodialysis Reliable Outflow (HeRO) device, skraćenog naziva HeRO-graft. Glavna je indikacija za primjenu ovoga krvožilnog pristupa okluzija ili značajna stenoza centralnih vena. Iz literature se doznaje da ovaj krvožilni pristup ima značajne prednosti u odnosu na tunelirani centralni venski kateter koji bi trebao biti zadnja opcija kod bolesnika koji zahtijevaju trajno nadomještanje izgubljene bubrežne funkcije. Za razliku od tuneliranih
katetera ovaj je sustav u potpunosti smješten potkožno, što ga čini otpornijim na infekcije. Do sada su u Kliničkoj bolnici Dubrava ugrađena dva HeRO-grafta za hemodijalizu i prema prvim iskustvima potrebna je detaljna obrada kandidata za ovu proceduru. Potrebno je dobro poznavati indikacije i kontraindikacije te je nužna suradnja više timova: nefrološkog, anesteziološkog, radiološkog i kirurškog. Osobito je potrebno obratiti pažnju na stanje arterijske cirkulacije okrajine koja se koristi za ovaj krvožilni pristup kako bi se izbjegle moguće ishemijske komplikacije. Kod obaju naših bolesnika postupak ugradnje protekao je uredno te smo započeli s korištenjem HeRO-grafta za potrebe hemodijalize.
Background. Campylobacter fetus rarely causes gastrointestinal diseases but shows an affinity for the endovascular epithelium. Methods. We describe a case of C. fetus bacteremia related to vascular ...prosthesis and pseudoaneurysm infection, with a review of the literature. Results. A 67-year-old male was admitted with a history of fever, weakness and painful swelling of the groin. After unsuccessful treatment with ciprofloxacin, the patient was transferred to our hospital, where he had been previously treated for aortoiliac occlusive disease including a prosthetic aortobifemoral and popliteal bypass with polyester graft placement. An angiography showed a pseudoaneurysm in the groin and, therefore, repair of the pseudoaneurysm, removal of the prosthesis and biologic graft placement were performed. Blood cultures and tissue samples of the vascular prosthesis and pseudoaneurysm yielded C. fetus resistant to ciprofloxacin. The patient was treated with meropenem for four weeks, followed by amoxicillin-clavulanate for another two weeks after discharge. Eight previously published cases of C. fetus bacteremia due to infected cardiovascular prosthetic devices (prosthetic heart valves, implantable cardioverter-defibrillators and a permanent pacemaker) were summarized in the review. Conclusions. To our knowledge, this is the first report of a C. fetus bacteremia related to post-surgical infection of a vascular prosthesis causing a pseudoaneurysm.
The goal of vascular access creation is to achieve a functioning arteriovenous fistula (AVF) or arteriovenous graft (AVG). An autologous fistula has been shown to be superior to AVG or to central ...venous catheters (CVCs) with lowest rate of re-intervention, but vessel obstruction or immaturity accounts for 20 % to 54% of cases with primary failure of AVF. This review is focused on the factors influencing maturation; indication and timing of preoperative mapping/creation of vascular access; ultrasound parameters for creation AVF/AVG; early postoperative complications following creation of a vascular access; ultrasound determinants of fistula maturation and endovascular intervention in vascular access with maturation failure. However, vascular accesses that fail to develop, have a high incidence of correctable abnormalities, and these need to be promptly recognized by ultrasonography and managed effectively if a high success rate is to be expected. We review approaches to promoting fistula maturation and duplex ultrasonography (DUS) of evaluating vascular access maturation.
Quality assessment in vascular access procedures for hemodialysis is not clearly defined. The aim of this article is to compare various guidelines regarding recommendation on quality control in ...angioaccess surgery. The overall population of end-stage renal disease patients and patients in need for hemodialysis treatment is growing every year. Chronic intermittent hemodialysis is still the main therapy. The formation of a functional angioaccess is the cornerstone in the management of those patients. Native (autologous) arteriovenous fistula is the best vascular access available. A relatively high percentage of primary failure and fistula abandonment increases the need for quality control in this field of surgery. There are very few recommendations of quality assessment on creation of a vascular access for hemodialysis in the searched guidelines. Some guidelines recommend the proportion of native arteriovenous fistula in incident and prevalent patients as well as the maximum tolerable percentage of central venous catheters and complications. According to some guidelines, surgeon’s experience and expertise have a considerable influence on outcomes. There are no specific recommendations regarding surgeon’s specialty, grade, level of skills, and experience. In conclusion, there is a weak recommendation in the guidelines on quality control in vascular access surgery. Quality assessment criteria should be defined in this field of surgery. According to these criteria, patients and nephrologists could choose the best vascular access center or surgeon. Centers with best results should be referral centers, and centers with poorer results should implement quality improvement programs.
We report of a patient with abdominal aortic aneurysm and renal transplant who underwent aneurysm repair. These patients can be treated by eather open or endovascular approach, depending on several ...factors, including aneurysm morphologic suitability for endovascular tretament, age of patient, and comorbidities.The main challange with open repair approach is to maintain renal transplant perfusion during the aortic cross clamping. Several methods of renal transplant perfusion during aneurysm repair have been described. In this case, we opted for open aneurysm repair beacuse of the age of the patient. The femoral venoarterial perfusion technique using extracorporal circulation machine was employed. We found this technique safe and easy in treating such patients.
