Congenital renal arteriovenous fistula associated multiple renal arteries and thoracic scoliosis: a case report / 中华泌尿外科杂志

A recurrent misdiagnosed case of congenital left renal arteriovenous fistula (RAVF) with multiple left renal arteries and scoliosis was reported. The patient was admitted to hospital on 29 August 2020 due to repeated hematuria for one year. No abnormality was found in two flexible ureteroscope examinations, imaging and laboratory examinations after admission. It was found that the structure of blood vessels in the inferior pole of renal sinus was disordered, and the blood vessels were tortuous and clustered through careful reading of CT enhancement films. The dilated tortuous blood vessels were also seen around the renal pelvis, and hematuria was considered to be caused by renal vascular malformation. In order to confirm the etiology, digital subtraction angiography (DSA) of renal artery was performed. DSA showed a congenital left renal RAVF with three renal arteries, and the arteriovenous fistula of renal arteries was embolized. For patients presenting with severe gross hematuria, if tumor, stone, tuberculosis, or coagulation abnormalities were excluded by conventional imaging and/or laboratory examination the possibility of congenital renal vascular malformation should be suspected, and DSA examination should be performed. Endovascular embolization is an effective treatment for congenital RAVF.

Fístula arteriovenosa renal espontánea como causa de hematuria: Presentación de un caso / Spontaneous Renal Arteriovenous Fistula-Caused Hematuria: Case Report

Objetivo: presentar un caso de fístula arteriovenosa renal espontánea atendido en el Hospital General Regional No. 1 "Gabriel Mancera" del Instituto Mexicano del Seguro Social. Reporte de caso: mujer de 27 años de edad, sin antecedentes de importancia quien se presenta con hematuria macroscópica, total, intermitente, con coágulos, silente y que le provocó anemia grave. Se realiza ureterorenoscopia izquierda y arteriografia renal diagnósticas. Se trató mediante embolización arterial selectiva percutánea con alcohol absoluto. La paciente evolucionó favorablemente y sin complicaciones. A un año de seguimiento se mantiene asintomática y sus estudios de laboratorio son normales. Discusión: la fístula arteriovenosa renal espontánea es un padecimiento raro puesto que la mayor parte de los casos se relaciona con antecedentes de traumatismo renal o cirugía. El tratamiento mediante embolización arterial es muy eficaz y su pronóstico excelente.

Objective: to present a case of spontaneous renal arteriovenous fistula treated at the Hospital Regional General No. 1 "Gabriel Mancera" of the Instituto Mexicano del Seguro Social (IMSS). Case Report: A 27-year-old female with no pathologic-medical background who presented with total, intermittent, macroscopic hematuria with clots as the only symptom causing severe anemia. Ureterorenoscopy and diagnostic renal arteriography were carried out. She was treated with percutaneous selective arterial embolization with absolute ethanol. The patientes experienced a favorable and uncomplicated evolution. After 1 year of follow-up, she remains asymptomatic and her laboratory parameters are normal. Discussion: spontaneous renal arteriovenous fistula is a rare disease; the majority of the cases are related to renal trauma or renal surgery. Treatment by arterial embolization is very effective and prognosis is excellent.

A Case of Congenital Renal Arteriovenous Fistula / 대한비뇨기과학회지

Congenital renal arteriovenous fistula is a rare disease. Treatment of arteriovenous fistula can be obtained with conservative treatment, selective transcatheter embolization and surgical procedures. We report a case of congenital renal arteriovenous fistula that was treated with selective transcatheter arterial embolization of the renal artery.

Superselective arterial embolization with microcoils for congenital renal arteriovenous fistula / 대한비뇨기과학회지

Congenital renal arteriovenous fistula is a rare disease and manifested by gross hematuria, bladder tamponade and flank pain. We experienced one case of congenital renal arteriovenous firstula which was cirsoid type and treated with superselective transcatheter arterial embolization of four small segmental arteries. The microcoils made of platinum and synthetic fiber were used as theembolization modality.

Selective Arterial Embolization of Renal Arteriovenous Fistula Associated with Blunt Renal Trauma / 대한비뇨기과학회지

A renal arteriovenous fistula is a rare disorder despite the increasing number of cases reported since l960. Approximately more than 300 cases have been described sine the first case reported by Varela in l923. Most of these fistulas were acquired in origin and were found in recent years owing to the increasing use of angiography and needle biopsy of the kidney as diagnostic methods, the rise in violence and consequent renal trauma cases. Treatment has consisted of partial nephrectomy, ligation of the branch artery supplying the fistula and intentional embolization of the arterial branches, feeding the shunt by catheter. Unless cardiovascular complications are present, salvage of the residual part of the involved kidney is possible. Herein, we report a case treated successfully by transcatheter embolization and review the literatures with emphasis upon the salvage of the renal function.

Congenital Renal Arteriovenous Fistula / 대한비뇨기과학회지

Congenital renal arteriovenous fistulas are rare clinicopathologic entities usually first manifested by hematuria. Renal angiography or isotopic scan establishes the diagnosis. We report a case of congenital arteriovenous fistula confirmed by renal angiography with review of literatures.

Renal Arteriovenous Fistula after Renal Injury: Report of 2 Cases / 대한비뇨기과학회지

Penetrating and blunt abdominal trauma may injure the renal vasculature with to the renal circulation. The natural history of `missed` vascular injuries has been well documented and the emphasis of modern trauma management has been toward early diagnosis surgical management. We present 2 cases of `missed` renal arteriovenous fistula diagnosed by selective renal angiography at 13 years after explosive war injury and 6 months after blunt trauma with brief review of relevant literature.

Acquired Renal Arteriovenous Fistula: A Case Report and Review of the Literature / 대한비뇨기과학회지

Renal arteriovenous fistula is a relatively rare disease, which was first described by Varela in 1923. Most of these have been diagnosed in recent years because of the increasing use of both percutaneous needle biopsy of the kidney and renal arteriography as diagnostic tools. We report one case of intrarenal arteriovenous fistula after stabbing, diagnosed by selective renalarteriography, with the review of literatures.
