Acute renal impairment due to a primary aortocaval fistula is normalised after a successful operation. (1/638)

OBJECTIVES: To study renal function in patients with aortocaval fistula, before and after surgery. DESIGN: Retrospective study. MATERIAL AND METHODS: During the last 22 years nine male patients (median age 67, age range 50-72) with spontaneous aortocaval fistula in combination with AAA were operated upon. This constitutes 4% of the patients with ruptured AAA and 1.5% of all patients with AAA. RESULTS: A preoperative diagnosis of aortocaval fistula was established in three of the nine cases. The medium duration of symptoms prior to surgery was 5 days (range 4 h-14 days). The fistula was combined with an extravasating ruptured AAA in only three patients. Seven of the patients had acute renal insufficiency, with creatinine levels of in median 292 mumol (IQR 218-342). Creatinine declined to 172 mumol/l (IQR 170-313) on the fifth postoperative day in uncomplicated cases and to 86 mumol at discharge. One patient died due to multi-organ failure, whereas the other left hospital well and alive with normal renal function. CONCLUSION: Acute preoperative renal insufficiency due to an aortocaval fistula in patients with AAA is often due to venous congestion, and is normalised after successful surgery.  (+info)

In vitro models of intracranial arteriovenous fistulas for the evaluation of new endovascular treatment materials. (2/638)

BACKGROUND AND PURPOSE: The purpose of this study was to create and test an in vitro model of intracranial arteriovenous fistulas (AVFs) that simulates the geometry of human vasculature and allows realistic testing of devices used in endovascular therapy. METHODS: The models were derived from corrosion casts of the main cervicocranial arteries and veins obtained from two nonfixed human specimens. Wax copies of the casts were produced and combined to create complex models simulating various types of intracranial AVFs. Wax assemblies were embedded with liquid silicone solidified into transparent blocks containing, after wax evacuation, hollow reproductions of the original vascular trees. The models were connected to a pulsatile pump and their compatibility with various imaging techniques and endovascular treatment materials was evaluated. RESULTS: The models were compatible with digital subtraction angiography, CT, MR imaging, and transcranial Doppler sonography. They provided a realistic endovascular environment for the simulation of interventional neuroradiologic procedures. CONCLUSION: Anatomically accurate and reproducible in vitro models of intracranial AVFs provide a valuable method for evaluating new endovascular treatment materials and for teaching purposes.  (+info)

The case of a cyanotic infant with a rare combination of atypical pulmonary artery sling, imperforate anus, absence of the left kidney, interruption of the inferior vena cava, left side hemihypertrophy and diffuse-type pulmonary arteriovenous fistula is described. The clinical features were confusing, because of compounding abnormalities involving the respiratory tract and pulmonary circulation. The diagnostic approach to the etiology of cyanosis is discussed and the embryonic origin of pulmonary artery sling is reviewed.  (+info)

Early prenatal diagnosis of cord entanglement in monoamniotic multiple pregnancies. (5/638)

OBJECTIVES: Cord entanglement is a severe complication in monoamniotic multiple pregnancies. Three cases were reviewed to determine how early ultrasound diagnosis might improve counselling and management. METHODS: In two monoamniotic twin and one dichorionic diamniotic triplet pregnancies, cord entanglement was detected between 10 and 18 gestational weeks by color Doppler and pulsed Doppler velocimetry. Pregnancies were followed up on a weekly basis with special observation of fetal behavior and use of color Doppler velocimetry. RESULTS: In Case 1, a monoamniotic twin pregnancy with cord entanglement close to the umbilical insertions was diagnosed at 10 weeks. Longitudinal follow-up showed intrauterine death of both twins at 15 weeks. In Case 2, entanglement of the umbilical cords of two monoamniotic triplets within a dichorionic diamniotic triplet pregnancy was diagnosed at 10 weeks. The pregnancy continued uneventfully until 35 weeks when cord entanglement was confirmed at Cesarean section. All triplets have since developed normally. In Case 3, monoamniotic twins were diagnosed at 18 weeks. Color Doppler detected side-by-side insertion of the umbilical cords and Doppler velocimetry suggested an entanglement at the chorionic plate. The pregnancy was complicated by polyhydramnios. Cesarean section at 36 weeks confirmed cord entanglement at the chorionic plate. Postnatal computer angiography and morphological examination of the placenta showed the presence of superficial artery-to-artery and vein-to-vein anastomoses and of deep arteriovenous shunts. The development of the twins was uneventful. CONCLUSIONS: Diagnosis of cord entanglement is feasible early in gestation. Future protocols are proposed to document the gestational age at detection, the location, and the Doppler flow patterns and to facilitate the assessment of short- and long-term development.  (+info)

Multiple dural arteriovenous shunts in a 5-year-old boy. (6/638)

We describe a rare case of multiple dural arteriovenous shunts (DAVSs) in a 5-year-old boy. MR imaging performed at 1 year of age showed only a dilated anterior part of the superior sagittal sinus; however, angiography at 5 years of age revealed an infantile-type DAVS there and two other DAVSs of the adult type. The pathophysiological evolution of DAVSs in children and their treatment strategies are discussed.  (+info)

3D Ultrasound imaging--a useful non-invasive tool to detect AV fistulas in transplanted kidneys. (7/638)

BACKGROUND: A precise, non-invasive, non-toxic, repeatable, convenient and inexpensive follow-up of renal transplants, especially following biopsies, is in the interest of nephrologists. Formerly, the rate of biopsies leading to AV fistulas had been underestimated. Imaging procedures suited to a detailed judgement of these vascular malformations are to be assessed. METHODS: Three-dimensional (3D) reconstruction techniques of ultrasound flow-directed and non-flow-directed energy mode pictures were compared with a standard procedure, gadolinium-enhanced nuclear magnetic resonance imaging angiography (MRA) using the phase contrast technique. RESULTS: Using B-mode and conventional duplex information, AV fistulas were localized in the upper pole of the kidney transplant of the index patient. The 3D reconstruction provided information about the exact localization and orientation of the fistula in relation to other vascular structures, and the flow along the fistula. The MRA provided localization and orientation information, but less functional information. Flow-directed and non-flow-directed energy mode pictures could be reconstructed to provide 3D information about vascular malformations in transplanted kidneys. CONCLUSION: In transplanted kidneys, 3D-ultrasound angiography may be equally as effective as MRA in localizing and identifying AV malformations. Advantages of the ultrasound method are that it is cheaper, non-toxic, non-invasive, more widely availability and that it even provides more functional information. Future prospective studies will be necessary to evaluate the two techniques further.  (+info)

Aortocaval fistula in ruptured aneurysms. (8/638)

OBJECTIVES: to study incidence, clinical presentation and problems in management of aortocaval fistula in our series. DESIGN: retrospective study. MATERIALS: during a seven-year period, 112 patients operated on for abdominal aortic aneurysm, including four patients with aortocaval fistula. METHODS: standard repair of aortocaval fistula from inside the aneurysmal sac was the preferred operative technique. RESULTS: the incidence of aortocaval fistula was 3.6%. Three cases were found incidentally during emergency surgery for ruptured aneurysms; the fourth case was an isolated aortocaval fistula associated with inferior vena cava thrombosis, diagnosed preoperatively by angiography. In this case, inferior vena cava ligation instead of standard aortocaval repair was performed. CONCLUSIONS: Aortocaval fistulas, although rare, should be kept in mind, because clinical diagnosis is often difficult. Furthermore, unsuspected problems during repair may necessitate appropriate change in operative technique.  (+info)

Objective To explore the possibility of establishment of experimental femoral pseudoaneurysm (PA) and traumatic arteriovenous fistula (tAVF) models in 40 rabbits and its related study. Methods Experimental PA and tAVF models were established in rabbit with microsurgical anastomosis technique. Models were checked by color Doppler flow imaging (CDFI), examined by computed tomography angiography (CTA), magnetic resonance angiography (MRA) and digital subtraction angiography (DSA). Results Sixteen femoral PA in 20 rabbits (80%) and 26 tAVF in 30 rabbits (87%) were successfully anastomosed and were confirmed by related examination methods. Conclusion It is possible to establish PA and tAVF experimental models in rabbits with microsurgical technique and each one of the above examination methods has its own characteristics. A combination of these examination methods may improve the diagnostic accuracy and treatment ability clinically.

Development of Pulmonary Arteriovenous Fistulae in Children After Cavopulmonary Shunt | CirculationDevelopment of Pulmonary Arteriovenous Fistulae in Children After Cavopulmonary Shunt | Circulation
PAVF have been postulated to represent the persistence of minute arteriovenous communications present in normal fetal and neonatal lung that enlarge to become fistulous and cause precapillary shunting and arterial desaturation.20 Gelatin-calcium carbonate, when injected into the pulmonary arteries of stillborn human fetuses, demonstrates vascular channels that bypass the alveolar capillary bed.21 These channels may play a role in the developing pulmonary circulation before the establishment of an alveolar capillary network.21 Neonatal lungs, therefore, may be more likely to retain these primordial arteriovenous connections and thus increase the susceptibility of younger patients to the development of clinically significant PAVF. We recently described the histopathology of microscopic PAVF in a 7-month-old infant with polysplenia and profound hypoxemia occurring 5 months after a cavopulmonary shunt.11 At autopsy, we found dilated pulmonary veins near the pleural surface and identified abnormal ...

Press Release issued Jan 3, 2018: Arteriovenous Fistula is a disruption of blood flow due to abnormal connection between a vein and artery. In condition of arteriovenous fistula, the blood flows directly from arteries to the vein, bypassing capillaries. Thus, capillary tissues receive less oxygen supply (i.e. blood supply) and increase the risk of blood pressure problem. Arteriovenous fistula can be congenital or acquired. Congenital fistula is formed during fatal development and majorly affects lower extremities of blood vessels.

Prenatal diagnosis of isolated coronary arteriovenous fistulaPrenatal diagnosis of isolated coronary arteriovenous fistula
To the best of our knowledge, this is the first report of a fistula between the left coronary artery and coronary sinus successfully diagnosed by prenatal echocardiography. To date, few cases of isolated CAVF have been diagnosed prenatally [4567891011]. All isolated CAVFs that were diagnosed prenatally drained into the cardiac chambers, and there were no cases with connections to the vascular structures rather than the cardiac chambers, such as the pulmonary artery, coronary sinus, and superior vena cava. In our case, prenatal ultrasonography was sensitive enough to diagnose CAVF draining into the coronary sinus.. Although the normal coronary artery is usually difficult to visualize prenatally because of the small size of the vessel, coronary malformations, such as CAVF, can be diagnosed with a high accuracy by fetal echocardiography. In this case, we clearly demonstrated the fistulous tract connected to the dilated coronary sinus. When the echocardiographic findings, such as cardiomegaly, ...

To compare the hemodynamic effects of a calcium-channel blocker with those of a conventional vasodilator in the awake preinstrumented dog, diltiazem and nitroprusside were administered in equihypotensive infusions before (decrease in mean aortic pressure by 10%; p less than .001, n = 6) and after (decrease in mean aortic pressure by 12%; p less than .001) chronic volume overload (CVO) produced by an infrarenal aortocaval fistula. Diltiazem had no effect on preload either before or after CVO. The maximal rate of change in left ventricular pressure (dP/dtmax) was unaffected by diltiazem before the aortocaval fistula (decrease in dP/dtmax by 6%; p = NS) but was significantly reduced by calcium-channel blockade after CVO (decrease in dP/dtmax by 22%; p less than .001). By contrast, at matched aortic pressures nitroprusside significantly reduced left ventricular end-diastolic dimension (LVEDD) and pressure (LVEDP) in the same animals before (decrease in LVEDD by 10%, p less than .05; decrease in ...

Methods and apparatus are provided for temporarily excluding an aneurysm or an arterio-venous fistula from a flow path by transluminally disposing a hollow balloon catheter structure within the aneurysm so that its proximal and distal ends extend past the aneurysm while maintaining continuity of the flow path, and then injecting a synthetic molding material or a biological hardening agent into the aneurysm cavity to cause solidification of the volume within the cavity. Once the material within the excluded aneurysm has solidified, the balloon catheter structure is deflated and removed, so that the hardened mass forms a new lining for the organ or vessel, and relieves the weakened tissue of the aneurysm or fistula from further flow-induced stress.

A vertebral-epidural spinal arteriovenous fistula (AVF) is an abnormal arteriovenous shunt connecting the vertebral artery to the spinal epidural venous plexus, and may occur spontaneously or secondary to a variety of causes. These unique lesions are uncommon in adults and rarer still in children. Previous reports have grouped together a heterogeneous collection of such arteriovenous lesions, including arterial contributions from the upper and lower vertebral artery, with venous drainage into a variety of spinal and paraspinal collectors. Here, through two cases, we delineate a distinct entity, the lower vertebral-to-epidural AVF. The salient clinical and anatomic features are summarized and contextualized within the broader constellation of vertebrovertebral AVF, the utility of a transarterial intravenous/retrograde intra-arterial endovascular approach is highlighted, and a new use of the Penumbra Occlusion Device (Penumbra Inc) for this purpose is reported.. ...

Introduction: Arteriovenous fistula (AVF) operation is recognized a gold standard of hemodialysis for end-stage renal disease. Because various complications may occur during perioperative period, medical care plays an important role in improving the possibility of AVF operation. The objective of the study was to explore the effect of the mode of multiple disciplinary team (MDT) medical care on the patients with end-stage renal disease treated by arteriovenous fistula (AVF) operation. Method: 98 patients with end-stage renal disease under the AVF operation were divided into observation group and control group. The control group was performed with regular medical care and for the observation group was treated under the mode of MDT medical care. Complications after operation, hospitalized time and medical satisfaction were comprehensively compared between the both groups. Results: The overall complications including swelling, bleeding, infection and thrombosis in observation group accounted for 5%, however

Normally blood flow begins in the arteries and travels to the veins through the capillaries, whereas AV fistulas bypass the capillaries. This can result in reduced blood supply to the tissues. AV fistula can also be created surgically and used during dialysis for people with kidney failure. Dialysis requires access to the cardiovascular system and over half of the people who need it use AV fistulas, which creates a larger and tougher blood vessel that can tolerate multiple needle punctures needed for dialysis. AV fistula, whether created surgically or caused by disease or trauma, should be monitored carefully since it can lead to severe complications. ...

Patients whose kidneys have failed need to receive dialysis treatment, most commonly with a dialysis machine. In order to be connected to the machine an operation is often performed to join an artery to a vein in the arm. This forms what is known as an arteriovenous fistula. The fistula causes an increase in the flow of blood through the vein and the vein reacts to this by becoming bigger and thicker, making it easier to connect the patient to the machine.. The success rate for the operation is relatively low and only approximately 65 from every 100 operations is still working after a year. It is thought that one factor that may cause problems with the fistula is the ability of the vein to stretch in response to increased blood flow. Previous research has shown that veins in kidney failure patients look different to those of people whose kidneys are working when viewed under a microscope.. The investigators aim to study the structure of the vein that is used in making fistulas with a microscope ...

The uncommon lesion: Dural fistula - Mayo ClinicThe uncommon lesion: Dural fistula - Mayo Clinic
MUSIC PLAYING] GIUSEPPE LANZINO: Dural fistulas are uncommon lesions, but it is very important for physicians to be aware of these possibilities because, quite often, patients can present with symptoms that might mimic more common conditions and may be misdiagnosed for a long period of time unless the possibility of a dural fistula is entertained early on in the course. A dural AV fistula is an abnormal communication between an artery and a vein, and they can occur both in the brain or in and around the spinal cord. The most common type of fistula is the so-called transverse sigmoid sinus fistula, and these patients often present with a bruit. Typically, if there is a fistula, a bruit can be also heard with a stethoscope, right in the mastoid area. And thats a fairly reliable sign. There are other fistulas located in the region of the cavernous sinus. They can present with ocular symptoms, paralysis of eye movement, decreased vision, redness of the eye and the conjunctiva. Its very common for ...

Cardiovascular disease is the leading cause of the death in patients receiving chronic renal replacement therapy.1-3 Arteriovenous fistulas (AVFs) have superior longevity, lower infection and mortality rates and are associated with lower cost, and hence have become the vascular access of choice for patients needing dialysis.4 Indeed, the prevalence of AVFs in the United States increased from 32% of all dialysis access in 2003 to 61% in 2012.5,6 Despite their association with a lower mortality, AVFs have significant effects on cardiac functions predominantly related to the increase in preload and cardiac output (CO). This article reviews the potential effects of the creation and the ligation of AVFs on cardiac function and their mechanisms.. It should be emphasized, at the outset, that determining the exact effects of AVFs on cardiac functions is fraught with problems for a couple of reasons: patients with end stage renal disease (ESRD) requiring dialysis almost invariably have volume overload ...

An arteriovenous fistula is an abnormal connection between the arterial and venous systems. In the literature, there are well-described ultrasound findings of iatrogenic arteriovenous fistula as a potential complication from percutaneous transarterial or transvenous procedures. The most important sign is direct visualization of the fistula in the place of the access site. It is necessary to look for secondary signs of arterialization of the veins, which can suggest a diagnosis of an arteriovenous fistula. However, the accuracy and diagnostic quality of duplex scanning in the diagnostics of a congenital or spontaneous arteriovenous fistula of the head and neck area in adults have been poorly described in the literature ...

A 58-year-old healthy man initially presented to the emergency room with gunshot wound (GSW) birdshot injuries to the back of his left leg that occurred on a hunting trip. His initial examination showed normal pulses without any localized neurologic deficits. He was reevaluated in the clinic 1 month later with a thrill in the popliteal fossa and diminished pedal pulses. A duplex ultrasound study confirmed an arteriovenous fistula (AVF) at the level of the proximal posterior tibial artery (PTA) or distal popliteal artery. An endovascular intervention resulted in successful coverage of the AVF and improvement of distal limb perfusion (Figure 1). ...

Adaptive and Pathological Reshuffling in the Venous Wall in Special Hemodynamic Conditions-Acquired Arteriovenous FistulaAdaptive and Pathological Reshuffling in the Venous Wall in Special Hemodynamic Conditions-Acquired Arteriovenous Fistula
Hemodialysis and peritoneal dialysis are the two possible choices in chronic renal disease in the uremic stage. Native arteriovenous fistula is susceptible to complications, some posing vital risk and requiring prompt treatment. We present the case of a patient undergoing hemodialysis on native AVF. An aneurism developed progressively on the arterialized cephalic vein. The AVF was abolished by closing the arteriotomy with a venous patch and excising the aneurismal venous segment. The pathology exam of the surgical specimen showed unequal vessel wall thickness due to hyperplasia of the media and subintimal space, with calcifications within the hyperplastic media.

February 7, 2018-TVA Medical, Inc. announced the presentation of an international meta-analysis of clinical experience in patients who received the companys everlinQ endovascular arteriovenous fistula (endoAVF) for hemodialysis access. The study analyzed data from 236 patients with end-stage renal disease (ESRD) at 28 centers in seven countries. The findings were presented by Tobias Steinke, MD, at LINC 2018, the Leipzig Interventional Course held January 30 to February 2 in Leipzig, Germany.. The company stated that the everlinQ endoAVF system is designed to create an arteriovenous fistula for hemodialysis access using an endovascular approach. In the procedure, two thin, flexible magnetic catheters are inserted into an artery and vein in the arm. A small amount of radiofrequency energy is used to connect the artery and vein to create the fistula. The catheters are then removed and a brachial vein is coil embolized, enabling future dialysis.. Dr. Steinke commented in the companys ...

Endovascular treatment is currently the favored method of SEDAVF treatment; the use of endovascular treatment has been reported in approximately two-thirds of pertinent studies and case reports.2 The rates of complete or near-complete occlusion of the SEDAVF with endovascular treatment ranged from 73.3% to 94.4%, and the rates of symptom improvement ranged from 62.5% to 91%.1⇓-3 Our study also demonstrated an excellent occlusion rate (100%) and good treatment outcomes (91%). Intradural venous drainage, noted in 53.8%7 of the 13 patients in this study, was seen with variable frequency in previous studies (27.0%2 to 74.5%4). In this study, ALS scores were zero in all patients without intradural venous drainage except for 1 patient who had mild leg weakness caused by compressive myelopathy.. Although endovascular treatment produced good outcomes in most patients in this study, 1 patient (case 7) could not recover from the congestive myelopathy symptoms, even after complete occlusion of the shunt ...

A five-year-old girl patient was admitted with cyanosis and dyspnea, which started from birth. She had small telangiectatic lesions on her face and cerebral arteriovenous malformation, but no family history of hereditary hemorrhagic telangiectasia. Contrast echocardiography and pulmonary angiography demonstrated diffuse pulmonary arteriovenous fistulas. The patient was diagnosed as polysplenia syndrome characterized with left atrial isomerism, interrupted inferior vena cava, azygous continuation to the superior vena cava, and hepatic veins draining to the right atrium. In contrast to the other polysplenia syndrome cases, in this patient, pulmonary arteriovenous fistulas were not associated with cavopulmonary anastomoses or liver disease.

Putie Hapsari, Teguh Marfen Djajakusumah, Zacky Fauzie, Muhammad Faiz Ulurrosyad. Introduction: Patients with end stage renal disease require hemodialysis. Radiocephalic arteriovenous fistula is the main choice of vascular access in patients who undergo hemodialysis procedure. Physiological vein distensibility is an important aspect in forming a mature arteriovenous fistula. This study aims to analyze the correlation between preoperative distensibility and arteriovenous fistula maturation.. Method: Data are collected from end stage renal disease patients in Hasan Sadikin Hospital and RA Habibie Hospitals that will go through radiocephalic arteriovenous fistula procedure during the period of October 2018 to February 2019. Vein distension procedure is performed before the operation and maturation is evaluated four to six weeks after the operation. The comparison of preoperative venous distensibility in two different groups of arteriovenous fistula maturation category is analyzed using chi square ...

Background and aim 9 patients with 10 arteriovenous fistulas were treated with Onyx at our institution over a period of 19 months 4 direct and indirect carotid-cavernous fistulas (CCFs) and 6 dural arteriovenous fistula (DAVFs). Complete occlusion was achieved with no recurrences or permanent complications in our small series. We report hemodynamic instability, including severe bradycardia and asystole, during embolization of DAVF and CCF with Onyx in several patients. These changes were reversible with interruption of Onyx injection and administration of atropine. No recurrence of symptoms after atropine administration was noted as Onyx embolization continued during the same session or during postprocedural 24 h monitoring. No adverse clinical consequences were noted.. Results Bradycardia was observed in four cases, with a brief asystole in two of these patients during transarterial and transvenous Onyx delivery at cavernous sinus and orbital levels. Based on our observation, hemodynamic ...

Evolution after treatment. The clinical response was favorable, with gradual improvement of motor deficit, regaining the ability to walk soon after hospital discharge. Two months later, the patient got significant improvement. The patient continued with rehabilitation and he had an almost complete recovery. One year after treatment, control arteriography was performed showing persistent occlusion of the DAVF.. Discussion. It is believed that spinal DAVFs (SDAVFs) are an acquired pathology, although its exact etiology is unknown. Arteriovenous communication occurs between a dural branch of the radicular artery, with the nest of vessels located in the dura near the radicular exit, and a vein, which drains intradurally into the venous perimedullary plexus.2,3 Dural arteriovenous fistulas (DAVFs) at the craniocervical junction are uncommon but they produce clinical important abnormalities. These lesions have two main forms of clinical presentation; acute subarachnoid hemorrhage (SAH) and ...

Their symptoms and prognosis are strongly related to the pattern of their venous drainage system. The presence of cortical venous reflux (CVR) is an aggressive feature indicating that there is a high risk of cerebral bleeding or progressive neurological deficits. Endovascular treatment has become the mainstream dAVF therapy. In general, trans-venous coil embolization is adapted to sinusal type dAVFs (i.e. ...

ARTERIOVENOUS FISTULA AND MULTIPLE SACCULAR ARTERIAL ANEURYSMS OF A FINGER, FOLLOWING CHILDHOOD HUMAN BITEARTERIOVENOUS FISTULA AND MULTIPLE SACCULAR ARTERIAL ANEURYSMS OF A FINGER, FOLLOWING CHILDHOOD HUMAN BITE
A case of acquired arteriovenous fistula with multiple aneurysmal sacs of the left fifth finger has been presented in an adult, resulting from a human bite in childhood. The digit, previously normal, showed characteristic physical chances of A-V fistula following the trauma, including increased growth, venous distension, increased local temperature and more rapid growth of the nail. In addition, there were occasional episodes of transient subungual spurting of arterialized blood over a 15-year period. Surgical excision of aneurysmal sacs and ligation of visible communications on two separate occasions resulted in the disappearance of symptoms, enabling the patient to resume her vocation as a typist ...

Accuracy of Peak Systolic Velocity of Radial Artery as Predictor of Maturation of Radiocephalic Arteriovenous Fistula in Cipto...Accuracy of Peak Systolic Velocity of Radial Artery as Predictor of Maturation of Radiocephalic Arteriovenous Fistula in Cipto...
Dedy Pratama, Richard Yehuda Limen, Akhmadu Muradi. Introduction: Hemodialysis is an essential treatment in patients with stage 5 chronic kidney disease (CKD) or End-Stage Renal Disease (ESRD). The maturity of arteriovenous fistulas determines the success of hemodialysis. FAV maturity depends on preoperative preparation. The study aims to examine the preoperative and intraoperative peak systolic velocity (PSV) of the radial artery as a predictor of the successful maturation of the radiocephalic FAV. Method: This study used an analytic cross-sectional design to obtain the relationship of FAV maturation with preoperative and intraoperative PSV. Subjects were those who will undergo radiocephalic FAV surgery with preoperative ultrasound mapping. Shortly after anastomosis, PSV was measured. After 6 weeks, FAV was assessed for its maturity. Results: As many as 71 patients were undergone radiocephalic FAV surgery and followed for six weeks. The mean preoperative PSV of mature fistula was significantly ...

A Comparison of Two Surgical Techniques for the Second Stage of Brachiobasilic Arteriovenous Fistula CreationA Comparison of Two Surgical Techniques for the Second Stage of Brachiobasilic Arteriovenous Fistula Creation
Two-stage transposed brachiobasilic arteriovenous fistula is a common procedure after brachiobasilic fistula (BBF) creation. Different techniques can be used for basilic vein transposition but few comparative literature reports are available. The aim of our study was to compare two different techniques for basilic vein transposition. The first maintains the BBF anastomosis and the basilic vein is placed in a subcutaneous pocket (BBAVF). The second transects the basilic vein at the BBF anastomosis and tunnels it superficially, with a new BBF in the brachial artery (BBAVFTn). From 2009 to 2014, all patients who underwent basilic vein superficialization were treated by one of the two techniques, recorded in a dedicated database and retrospectively reviewed. The surgeon chose the technique on the basis of personal preference. The two techniques were compared in terms of perioperative complications, length of hospital stay, time of cannulation, ease of cannulation, and long-term patency. Eighty ...

Venous Endothelium of Experimental Arteriovenous Fistulas in Rabbits | Circulation ResearchVenous Endothelium of Experimental Arteriovenous Fistulas in Rabbits | Circulation Research
Since hemodynamic factors have been implicated in the localization and pathogenesis of atherosclerosis, the effect of hemodynamic stress on endothelium was investigated. The endothelium of the inferior vena cava of 24 rabbits with aortocaval fistulas was stained in situ and examined by the Hautchen technique at postoperative intervals ranging from 1 to 50 weeks. Cell counts revealed that, in the anastomosed vein of the fistula, an initially high frequency of abnormal cells decreased 3-12 weeks postoperatively but rose again within 20-50 weeks to levels significantly higher than those in either normal venous endothelium or sham-operated veins. An originally high mitotic index at 1-2 weeks decreased with time but still remained significantly larger than that observed in sham-operated rabbits. In most rabbits with arteriovenous shunts, a small area of the inferior vena cava near the fistula was devoid of endothelium, covered with a thin deposit of mural thrombi, and considered to be a jet lesion. ...

Background To review outcomes of open and endovascular repair of aortocaval fistulas (ACFs) in the setting of abdominal aortic aneurysms (AAAs). 41 cases (61%). The rate of complication and the death in open repair were 36% and 12% respectively (= 0.327 and = 0.910 respectively) compared with endovascular. Mean follow-up was 7.7 months for the endovascular group and 8.5 months in the open group. Conclusions Previous demonstrations of high morbidity and mortality with open repair of ACF in the setting of AAA have motivated endovascular approaches. However endoleaks are a significant problem and were present in 50% of ACF cases. The continued presence of an endoleak in the SMO setting of an ACF may result in persistence of the ACF unlikely thrombosis of the endoleak and continued sac enlargement. Endovascular repair presents theoretical benefit yet is not associated with a reduced rate of complication or death versus open repair in this contemporary review. Introduction Aortocaval fistulas (ACFs) ...

Infections are a common complication among patients on chronic haemodialysis. Haemodialysis patients with a tunnelled dialysis line, or PermCath, have a 2-3 fold increased risk of hospitilisation for infection compared to those with an arterio-venous fistula or graft (reference). For this reason, we strive to have AV fistulas created for as many patients as possible, with the Renal Association guidelines recommended that 60% of patients have a mature AV fistula ready for use by the time they commence dialysis (reference - Renal Association). Infections associated with tunneled dialysis catheters can be fatal. The most common causative pathogens are Gram-positive bacteria, with Staphylococcus aureus and coagulase-negative staphylococci accounting for the majority of infections..
