Role Of Renal Artery Embolization In Treatment Of Iatrogenic Renal Bleeding.

Objectives: To review institutional experience about the effectiveness and safety of percutaneous trans-arterial renal artery embolization in the treatment of iatrogenic renal bleeding. Method: The prospective study was conducted from December 2019 to December 2021 at Ain Shams University Hospital and Kafrelsheikh University Hospital, Egypt, and comprised patients of either gender who underwent renal artery embolization for iatrogenic arterial renal bleeding caused by percutaneous nephrolithotomy, renal biopsy and percutaneous nephrostomy. Diagnostic renal angiography was done to detect pseudoaneurysm and arteriovenous fistula. Embolization was done with either micro-coils or glue. Success of the procedure was defined astotal occlusion of the bleeding artery proved by post-embolization angiogram. RESULTS: Of the 15 patients, 9(60%) were males and 6(40%) were females. The overall mean age was 35+/-14 years. Percutaneous nephrolithotomy was the main cause 8(53.3%), followed by renal biopsy 5(33.3%) and percutaneous nephrostomy 2(13.2%). There were 9(50%) cases of pseudoaneurysm and 6(40%) of arteriovenousfistula. Embolization was done with micro-coils in 5(33.3%) cases and with glue in 10(66.6%). The technical success rate was 15(100%). No major complicationsrequiring intensive care orsurgical intervention were encountered, and there was no significant differences in estimated glomerular infiltration rate or renal function after renal artery embolization (p>0.05). CONCLUSIONS: Percutaneous endovascular renal artery embolization was found to be a safe and effective technique in the management of iatrogenic renal arterial injury.

Tale of a wandering spleen: 1800 degree torsion with infarcted spleen and secondary involvement of liver.

Wandering spleen is a rare clinical entity characterized by splenic hypermobility resulting from laxity or maldevelopment of the suspensory splenic ligaments. The spleen can "wander" or migrate into various positions within the abdomen or pelvis due to this ligamentous laxity. It is usually detected between 20 and 40 years of age, and is more common in women. The clinical presentation of a wandering spleen is variable, it could present as an asymptomatic, incidentally detected, abdominal or pelvic mass, or as an acute abdomen secondary to splenic torsion. Diagnosis in an emergent setting can be challenging as it is a rare cause of acute abdomen and does not produce any symptoms until splenic torsion has occurred. We present and discuss a case of ectopic, torsed spleen resulting in complete infarction of the spleen and severe hepatic vascular compromise, diagnosed by ultrasound, confirmed by computed tomography and effectively managed by splenectomy.
