Anatomy of renal arterial supply

Abstract

A thorough knowledge of the variations of the renal artery has grown in importance with the increasing numbers of renal transplants, vascular reconstructions, and various surgical and radiologic techniques. The literature indicates that multiple renal arteries are found in 9- 76% of cadavers. The purpose of this study is to establish the incidence and characteristics of variations of renal arteries in Thais. A total of 267 Thai cadavers were dissected in the anatomy laboratory. The anatomical findings included: a single hilar artery in 82% of cases; double renal arteries in 17% of cases (one hilar artery with an upper polar artery occurred in 7%; two hilar arteries in 7%, and one hilar artery combined with one lower polar artery in 3%); and triple renal arteries occurred in 1% (two hilar arteries with one upper polar artery in 0.4% and two hilar arteries with one lower polar artery in 0.6%). In preparation for interventions, such as living renal donation, vascular reconstruction, renovascular hypertension, or radical nephrectomy, the results indicate that preoperative renal imaging is necessary and that operative techniques with attention to multiple renal arteries should be considered.

Accessory Renal Arteries: A Cadaveric Study

“…Accessory arteries were also seen both at the poles and at the hilum. 10,25 The findings of the present studies were consistent with the previous studies. Accessory arteries were not seen at the hilum.…”

“…Some authors have reported a higher frequency on the left, 9,13,22,23 where as others have found it to be more frequent on the right side. 7,10,14 In the present study, accessory renal arteries were observed more on the left (63.63% )than on the right side (36.36%).…”

“…Most workers have found accessory arteries in 15-35% of the kidneys in their studies [8][9][10][11][12][13] . However Budhiraja 14 reported 11.66% and Elvira Talovic 6 reported 46.15%.…”

Estudo do padrão arterial de 200 pedículos renais por meio de angiotomografias

“…Usually, these vessels originate from the aorta or common iliac arteries between the levels of T11 and L4. Rarely, they may originate from the suprarenal artery, the celiac trunk, superior mesenteric, inferior mesenteric, median sacral and phrenic arteries [9][10][11] . In General, the arteries which irrigate the renal poles are thinner then the hilar renal arteries from the main renal arteries 12,13 .…”

Arterias Renales Múltiples

“…En la mayoría de los individuos se encuentra una arteria renal a cada lado, la que se divide previamente a su ingreso en el hilio renal, en dos o más ramas, (Testut & Latarjet, 1969;Dangelo & Fattini, 1988;Williams et al, 1995;Moore & Dalley, 2002;Khamanarong et al, 2004). Este padrón no está exento de variaciones, ya que se han descrito arterias renales dobles, uni o bilaterales (Tanyeli et al, 2006) o en menor porcentaje, tres arterias renales (Khamanarong et al;Raheem et al, 2007). Considerando la importancia de comunicar estas variaciones anatómicas, se presenta una inusual disposición de tres arterias renales.…”
