To the Editor,

Arteriovenous fistulas of the kidney are rare. They may be acquired, idiopathic or congenital. With the advent of interventional procedures such as percutaneous needle biopsy and percu­taneous renal access, iatrogenic fistula have become more frequent. [1] The acquired fistula after a penetrating trauma usually present with hematuria or hypertension. The time to pre­sentation following trauma may vary.

We report a case of penetrating trauma to the kidney presenting fifteen years after injury.

A 32-year-old male sustained a stab injury to the abdomen 15 years ago. He underwent emer­gency left hemicolectomy and then was appa­rently well, till he was detected to have hyper­tension during health checkup. His blood pre­ssure was 160/100 mmHg and was uncon­trolled on three antihypertensives. Duplex ultra­sound revealed a normal right kidney, bulky left kidney with focal upper calyceal dilatation and an aneurysm in the region of the left renal upper pole. Computerized tomographic (CT) angiogram revealed an aneurysm of the upper segmental artery [Figure 1]A with upper caly­ceal dilatation, and a massively dilated left re­nal vein due to arteriovenous (AV) shunting [Figure 1]B. He underwent coil embolization of the segmental artery to the upper pole [Figure 2]. At two years follow up, his hyperten­sion is under control with a single antihyper­tensive and repeat CT angiogram confirmed no evidence of AV shunting [Figure 3]. Most AV fistulae can be managed with embolization. [2]

There is little data available on hypertension following treatment of arteriovenous fistulas. Hypertension associated with arteriovenous malformations was cured in 62% of the cases after surgical treatment and surgical success was higher in patients with acquired post­traumatic fistula. [3],[4]
