“…This necessitates the use of microcatheters to effectively treat the lesions and minimize the loss of viable tissue [5,11]. Different kinds of embolic materials have been reported to be used in renal artery embolization, namely polyvinyl alcohol particles (PVA), embosphere, gelfoam, coils, and glue [1,10]. When embolization is performed with PVA, particles can form a plug inside the lumen of the microcatheter, causing the operator to apply excessive pressure and lose control of delivery.…”

“…It is a very effective material for use with larger lumen catheters, but not as effective in our experience in the distal small branches of the renal artery. Gelfoam has been reported to be used with success [1]. It is absorbed a few weeks after the embolization long after the bleeding stops.…”

“…Detachable coils are an alternative, but the small diameters of the distal branches usually do not allow the use of this material because the coils do not have enough space inside the lumen to reproduce their predefined shapes. They can be used in long-standing fistulas where the lesion and the feeding branch are much larger or as an additional measure at the proximal end of the area of embolization [1]. Another problem is the cost of these coils compared to glue, and this can be a deterring cause in their use.…”

“…Injury to the intrarenal arterial system can cause an arteriovenous fistula and/or pseudoaneurysm [1][2][3][4][5]. Endovascular embolization is accepted as the recommended treatment of these lesions [2,6,7].…”

Transarterial glue embolization in iatrogenic renovascular injuries

Iatrogenic injuries of the intrarenal arterial system include pseudoaneurysms and fistulas. They can cause hematuria and life-threatening hemodynamic instability, and therefore should be treated promptly. Endovascular treatment is recommended for these cases due to its effectiveness. Among the different agents used for embolization, n-butyl-2-cyanoacrylate (glue) has rarely been used. We present 15 patients with pseudoaneurysms and/or arteriovenous or caliceal fistulas who were treated by glue embolization. In our patient group, five had a history of percutaneous nephrolithotomy, six had renal biopsies, three had nephron-sparing surgery, and one had percutaneous nephrostomy. Glue embolizations were performed with the microcatheter technique. All patients were successfully treated, and all but one had excellent follow-ups. One patient suffered from disseminated intravascular coagulation secondary to transfusion and died after the procedure. We think glue embolization is a safe and effective treatment for this group of patients and present our experience along with the technical approach.

“…There may be a predilection for hemangiomatous lesions to occur in women, especially within the right kidney; this was observed in our series and has been described by others Acquired renal AV fistulas are usually post-traumatic in origin. Renal biopsy is considered the most common cause (1,7,21). These lesions are more likely to occur in patients with nephrosclerosis and arterial hypertension (2).…”

Abnormal renal arteriovenous communications were documented by renal angiography in 21 patients. Included were congenital malformations, traumatic fistulas and spontaneous fistulas associated with renal arterial disease. Each type exhibited characteristic angiographic features. Overt clinical manifestations were observed in more than half the cases. Specific treatment depended upon type, location and size of the arteriovenous communication. Small, covert renal fistulas and malformations were managed conservatively. Five medium size symptomatic intrarenal arteriovenous fistulas and one malformation were successfully treated by transcatheter embolization. Large lesions, especially when associated with renal arterial disease, may be more appropriately treated by surgery.
