Congenital renal arteriovenous fistula presenting with gross hematuria and its management.

ABSTRACT: Renal arteriovenous fistula (AVF), an abnormal connection between artery and vein, results from development failure or following vascular injury. AVFs may cause various complications, i.e., secondary hypertension and hematuria. To manage AVF, it is recommended to bypass it from blood circulation surgically or by percutaneous embolization. The present study describes a woman with AVF, who primarily was managed percutaneously and then surgically.

Renal arteriovenous fistula simulating hydronephrosis: A case report.

Project description:IntroductionAcquired renal arteriovenous fistulas (AVFs) include those that occur as a complication of renal biopsy.Case reportThe authors report the case of a woman with recent-onset grade I hypertension, who was referred to our staff for sonographic studies of the kidneys and urinary tract. Laboratory data revealed microhematuria and proteinuria <0.5 g/24 h, and renal function was borderline (MDRD GFR 58 mL/min). Renal sonography of the left kidney revealed an anechoic, arboriform area at the level of the pelvis, which was suggestive of hydronephrosis. The color Doppler examination showed turbulent flow within the anechoic area, with high-velocity arterial flow and arterialization of the venous waveform at spectral analysis. Selective renal angiography later confirmed the presence of a middle renal AVF with pseudoaneurysm, which had been provoked by a renal biopsy performed over 10 years earlier in another center. Since the patient was currently in good health, the prescribed management consisted solely of close clinical and US follow-up.DiscussionAV fistulas are among the most commonly diagnosed renovascular malformations. The case reported here underlines the importance of using color Doppler ultrasound when obstructive uropathy is suspected, especially in patients who have undergone renal biopsy.

Orbital arteriovenous fistula presenting with choroidal pulsations on optical coherence tomography.

Project description:PurposeTo describe a case of orbital arteriovenous fistula diagnosed based on choroidal pulsations on optical coherence tomography (OCT).ObservationsA 69-year-old female originally referred for evaluation of macular degeneration. During acquisition of OCT images, choroidal pulsations of the right eye were noted on the B-scan on the instrument display. The pulsations were not noted on gross or funduscopic examination. Fluorescein angiography was unremarkable. Indocyanine green angiography revealed engorged choroidal vasculature in the right eye. OCT angiography revealed relative tortuosity and dilation of the superficial and deep vascular complexes respectively. B-scan ultrasonography revealed orbital pulsations on the right. MRI imaging of the brain and orbits was unremarkable. Findings were attributed to a low-flow orbital arteriovenous fistula. The patient subsequently developed mild stasis retinopathy for which anti-VEGF therapy was initiated.Conclusions and importanceArteriovenous fistulas of the brain and orbit classically present with gross pulsatile proptosis among other clinical features. Low flow orbital fistulas may present with subtle choroidal pulsations only detectable on OCT.

Fibroepithelial Polyp at the Bladder Neck Presenting with Gross Hematuria in a 5-Year-Old Boy.

Project description:Background: In any age group, gross hematuria is an alarming symptom. A variety of diseases, including urinary tract tumors, urinary tract infections, glomerulonephritis, urinary stone disease, and urinary trauma, can cause gross hematuria. Neoplasms of the urinary tract are definitely the most bothersome among the differential diagnoses. Fibroepithelial polyps (FEPs), in contrast, are mesodermal-originated rare and benign tumors that can be observed in the urinary tract. In this case report, we present a child with an FEP at the bladder neck that was referred because of gross hematuria. Case Presentation: A 5-year-old boy presented with intermittent gross hematuria for 2 weeks. Ultrasonography showed a 2 × 1 cm mucosal surface-borne polypoid lesion at the trigon. Patient underwent cystoscopic evaluation that revealed a polypoid mass located at the bladder neck; however, there were no signs of bladder outlet obstruction in the bladder. Transurethral resection revealed an FEP. Conclusion: Hematuria should be evaluated carefully not only in adults but also in children. FEPs in bladder can mimic bladder carcinoma clinically and radiologically. It should be kept in mind in the differential diagnosis of bladder lesions on imaging modalities in pediatric population.

Updates in the management of cranial dural arteriovenous fistula.

Project description:Dural arteriovenous fistula (dAVF) accounts for approximately 10% of all intracranial vascular malformations. While they can be benign lesions, the presence of retrograde venous drainage and cortical venous reflux makes the natural course of these lesions aggressive high risk of haemorrhage, neurological injury and mortality. Endovascular treatment is often the first line of treatment for dAVF. Both transarterial and transvenous approaches are used to cure dAVF. The selection of treatment approach depends on the angioarchitecture of the dAVF, the location, the direction of venous flow. Surgery and, to a lesser extent, stereotactic radiosurgery are used when endovascular approaches are impossible or unsuccessful.

Endovascular management of aortocaval fistula complicating abdominal aortic aneurysm presenting as an acute renal failure.

Project description:IntroductionAortocaval fistulas (ACFs) are a rare complication of abdominal aortic aneurysm (AAA), associated with high morbidity and mortality. It is thought that increased tension in the walls of large aneurysms can cause an inflammatory reaction resulting in adhesion to the adjacent vein and culminating in necrosis of the adherent layers and fistula formation.Presentation of caseA 70-year-old male was referred from a local state center to the emergency department of our hospital, complaining of weakness and oliguria for two days. The laboratory analysis yielded high urea and creatinine levels, indicating an acute renal failure. Computed tomography images showed an aortocaval fistula complicating infrarenal abdominal aortic aneurysm. The patient was successfully managed with endovascular intervention.DiscussionAortocaval fistulas generally affect elderly men with an average age of 65 years. The diagnosis is often delayed because of the variable clinical manifestations, which increases the difficulties in treatment. Conventional surgical intervention has high mortality rates. However, endoleaks and paradoxical pulmonary embolism are the main concerning complications of endovascular treatment.ConclusionSpontaneous aortocaval fistulas are a rare, but potentially life-threatening complication of abdominal aortic aneurysm with myriad clinical manifestations. Early diagnosis and management can directly affect the prognosis and outcome. Modern non-invasive diagnostic imaging can help timely diagnosis and provide a road map for the treatment plan. Endovascular repair is the first choice of treatment. However, a high incidence and persistence of endoleak with the endovascular approach requires caution and a close long time follow up.

Endovascular Occlusion of a Renal Arteriovenous Fistula with Renal Vein Aneurysm Formation for Rupture Prevention.

Project description:PurposeTo report the effectiveness of left renal artery (LRA) occlusion using Amplatzer Vascular Plug (AVP) II as treatment for a high-flow renal arteriovenous fistula (RAVF) with multiple renal vein aneurysms (RVA) to prevent aneurysm rupture and cardiac decompensation.Case reportA 59-year-old female suffering from a post-traumatic RAVF presented with tachycardia and increased cardiac output (CO). Doppler ultrasonography and computed tomography (CT) scan revealed a high-flow RAVF with multiple RVAs and unilateral critically reduced kidney function. Appreciating recent interventional therapeutic advances, the patient was treated with endovascular placement of AVP II into the left renal artery (LRA) resulting in complete occlusion of the RAVF to effectively reduce the risk of RVA rupture and cardiac decompensation. No anti-platelet medication was administrated after the occlusion of the LRA. The patient's physical capacity improved since right heart volume strain was normalized, and CO was reduced.ConclusionTransbrachial AVP II occlusion of the LRA is effective to occlude high-flow RAVFs to prevent risk of life-threatening RVA rupture. Additional follow-up is warranted to verify long-term effectiveness of this approach.
