Renal arteriovenous malformations (AVMs) are infrequent vascular morphological anomalies. About 20% of AVMs are congenital renal AVMs (CRAVMs). A 53-year-old female patient presented with a 5-day history of gross hematuria and right flank pain. The patient underwent the selective renal arteriography and embolization under local anesthesia. Renal computed tomography angiography (CTA) and digital subtraction angiography (DSA) results showed bleeding of the right renal arteriovenous malformation, both nidus and aneurysm, which indicated that the patient had both cirsoid and cavernosal types of CRAVM. Endovascular management was chosen to treat the patient. The patient was cured and discharged, then followed-up for 3 months. These results show that early identification using radiologic tests is important for diagnosis and treatment of CRAVM.

We report a case of renal arteriovenous malformation (AVM) and describe its angioarchitecture and endovascular management. A 28-year-old male patient presented with visible painless haematuria. CT of the abdomen showed a right renal AVM. Digital subtraction angiography of the right renal vessels showed an AVM of middle and lower pole segmental arteries with communication to a large saccular aneurysm, which was arising from the right main renal vein. Complete occlusion of the AVM was done by using glue (a mixture of n-butyl-cyanoacrylate and lipiodol), resulting in nonvisualisation of the aneurysm on angiography. His vital signs were stable during the procedure. Follow-up CT after 12 months showed no residual flow in the aneurysm, normal upper pole renal parenchyma and nonvisualisation of AVM. Early diagnosis of this clinical entity is of paramount importance for proper management as it can cause massive blood loss and rapid clinical deterioration.

Renal Arteriovenous Malformation

Purpose:to analyze the results of preoperative diagnosis and treatment of patients with renal arteriovenous malformation and compare them with the literature data.Materials and methods.5 patients with renal arteriovenous malformations were examined for the period from 2014 to2016 in the FSBI "A.V. Vishnevsky Institute of Surgery» MH RF, where simultaneously there are clinical departments of urology and vascular surgery, 4 of them were treated. All patients were female. The mean age was 31.8 ± 6.7 years (24–41 years). Ultrasound was done to all the patients in B-mode followed by a duplex scan using an abdominal 2–4 MHz convex. MDCT was performed in 4 patients out of 5. Patients underwent multiphase examination on a multidetector CT-scanner Philips Brilliance iCT-256 and Brilliance CT-64 (Philips Medical Systems (Cleveland) with the 120 kV and 100 kV protocols and an intravenous injection of the iodinated contrast agent. Digital subtraction angiography was performed in 3 patients.Results.One-sided lesion occurred in four cases (3 of them (60%) right-sided and 1 (20%) left-sided), in one patient (20%) arteriovenous malformation was bilateral As a result of the analysis of our own material and literature data, the diagnostic criteria of renal arteriovenous malformations according to ultrasound, MDCT and digital subtraction angiography were studied in detail. The results of the examinations of 5 patients with demonstration of ultrasound, MDCT and angiographic images are presented with the visualization of the characteristic features of renal AVM. In addition, the treatment options for such patients with the possibility of preserving the kidney are described.Conclusion.Duplex scanning is an effective method of diagnosis and postoperative follow-up of patients with renal arteriovenous malformations. Preoperative computed tomography and selective digital subtraction angiography provide accurate information about the renal angioarchitectonics and AV-shunts for choosing the treatment tactics and planning the surgical intervention.

Abstract Background To report a case of a cerebral Arteriovenous Malformation(AVM) with eye symptoms firstly and review the characteristic of this case and the main confusing point for diagnosis of such case. Case presentation A 58-year-old women presented to the ophthalmology clinic with 1 and an half year of right eye redness, Ocular hypertension and recurrent headache. One and a half year ago she was diagnosed as right eye dry eye and glaucoma and had received treatment according to diagnosis, however all the treatment did not lead to any improvement of redness and headache. On physical examination, it revealed dry eye and severe corkscrew hyperemia with dilated vessels in the right eye. After we consider that the symptom may be related to intracranial abnormal vessels, Computed tomography angiography and venography (CTA+CTV) were performed and the results showed an arteriovenous malformation (AVM) of right parietal-occipital area in the brain. The AVM was definitely located by the further examination of Digital subtraction angiography (DSA). After the AVM endovascular embolism treatment, the conjunctival congestion of the right eye was significantly relieved and the intraocular pressure was decreased to normal. Conclusion In clinical practice, when found corkscrew hyperemia accompanied by neurological symptoms, it might be considered as a result from cerebral vessels diseases, so in this case ophthalmologists diagnosis should combine disease history and imaging examination.

Carcinosarcomas of the urinary bladder are rare biphasic neoplasms, consisting of both malignant epithelial and malignant mesenchymal components, and the prognosis of this tumor is unfavorable in most patients with even possibility of resection of disease. A 77-year-old male with a history of transurethral resection (TUR) of urothelial carcinoma (UC) of the bladder and adjuvant intravesical chemotherapy with pirarubicin 10 years ago revisited our department with a gross hematuria. Cystoscopy demonstrated an approximately 2.5 cm nonpapillary tumor on the right wall of the bladder. Pelvic MRI showed the tumor without extending the base of the bladder wall. The tumor could be completely removed with TUR. The malignant epithelial elements consisted of high-grade UC and the majority of mesenchymal components were fibrosarcomatous differentiation based on immunohistochemical studies. The tumor could be pathologically also suspected to be an early stage on TUR specimens. Although he has received no additional intervention due to the occurrence of myocardial infarction at three weeks after the TUR, he has been alive with no evidence of recurrence of the disease 27 months after the TUR. Some early stages of bladder carcinosarcoma might have a favorable prognosis without aggressive treatments.

Infundibulopelvic dysgenesis is a rare condition characterized by congenital malformation of the pelvicalyceal system. We present the case of an 18-year-old boy with chronic intermittent right flank pain and cystic dilation with parenchymal thinning on ultrasonography. The left kidney was normal. The patient denied dysuria, constipation, and history of UTIs or renal calculi. Cystoscopy with retrograde pyelogram showed marked stenosis of the right pelvicalyceal system and anatomy unfavorable to stenting. The patient’s symptoms were unresponsive to conservative management. Reconstruction of the right collecting system was unsuccessful and a simple nephrectomy was performed, which led to complete resolution of his symptoms.

Abstract Background Heart failure is usually associated with a low-cardiac-output state; however, a minority of these patients are characterized by a high-output cardiac state, described as a cardiac index of > 4 L/minute/m2. Usually such circulation is associated with low systemic vascular resistance or arteriovenous malformation (AVM), resulting in depressurized circulation and a high-output cardiac state. Treating physicians should be cognizant of such pathology when investigating patients with heart failure. As an example, renal arteriovenous malformations are a rare vascular phenomena that are typically the result of iatrogenic, traumatic or congenital etiology. Generally, non-salient, most are detected as an incidental finding. Case presentation A 75-year-old Afro-Caribbean man with multiple comorbidities presented to the emergency department with a 6-month history of heart failure symptoms. Cardiac catheterization demonstrated a giant right renal AVM leading to a significant left-to-right, post-tricuspid shunt that was treated with transcatheter coiling. Conclusions We present this case to emphasize the significance of a detailed workup in a patient with heart failure symptoms.
