Abstract Background: The assessment of renal function is important to the prognosis of patients needing Fontan palliation due to the reconstructed compromised circulation. To know the relationship between the kidney perfusion and hemodynamic characteristics during surgical design could reduce the risk of acute kidney injury (AKI) and the postoperative complications. However, the issue is still unsolved because the current clinical evaluation methods are unable to predict the hemodynamic changes in renal artery (RA). Methods: We reconstructed a three-dimensional (3D) vascular model of a patient requiring Fontan palliation. The technique of computational fluid dynamics (CFD) was utilized to… More > Graphic Abstract

Abstract Renal artery aneurysms can present with gross hematuria and are potentially life-threatening in cases of rupture. We report a case of a young male with no prior genitourinary history who presents to an emergency department with sudden onset gross hematuria, clot retention, and right-sided flank pain. On evaluation, he was found to have a renal artery aneurysm bleeding into his collecting system and underwent renal artery embolization and rapid resolution of his hematuria. Renal vascular pathology should be considered in the differential diagnosis and timely diagnosis of this condition is imperative as surgical interventions have More >

Abstract Background: Renovascular hypertension (RVH) can be caused by renal artery stenosis (RAS) and/ or middle aortic syndrome (MAS).
Methods: Patients who received surgical or transcatheter treatment for RVH between 1/1991 and 11/2017 were retrospectively reviewed using age = adjusted blood pressure ratio (BPR).
Results: Fifty-three patients diagnosed with RVH at a median age of 4.5 (0–18) years were included. Vascular involvement ranged from MAS with RAS (20), RAS only (32), and MAS only (1). The first intervention was transcatheter in 47 patients (transcatheter group: angioplasty = 41, stenting = 5, and thrombectomy = 1), and surgical in 6… More >

Abstract A 46-year-old male with a history of hypertension presented with symptoms of persistent abdominal fullness and a non-pulsatile abdominal mass. Subsequent computed tomographic angiography studies revealed the presence multiple large renal aneurysms from the segmental branches of the renal artery and an enlarged hydronephrotic kidney with minimal parenchyma. The renal deterioration appeared to be as a result of an obstruction caused by the large intra-renal aneurysms at the level of the renal calyces. Since the right kidney had no function, an open radical nephrectomy was subsequently performed without complications at 3 months follow up. More >

Abstract Spontaneous retroperitoneal hematoma (SRH) is a rare, potentially lethal entity that can arise from a variety of etiologies. We present a case of SRH secondary to hemorrhage from the right inferior adrenal artery in a 22-year-old woman. The patient presented to the emergency room with significant right flank pain, and computed tomography (CT) demonstrated a large, right-sided retroperitoneal hematoma with no identifiable etiology. Renal angiography revealed active extravasation from the right inferior adrenal artery. The patient was definitively treated with endovascular coiling of the ruptured artery, and long-term follow-up demonstrated resolution of the retroperitoneal hematoma. More >

Abstract Renal artery pseudoaneurysms (RAPs) are vascular lesions that have most commonly been reported secondary to penetrating renal trauma and iatrogenic injury. We present the fi rst case of a RAP that developed as a result of an isolated deceleration injury. The patient presented 3 years after his injury with symptoms of gross hematuria, right fl ank pain, and syncope. Diagnosis of his RAP was made by magnetic resonance imaging (MRI) and angiography. He was successfully treated with angioembolization. More >

Abstract Objective: To compare kidney oxygenation profiles between partial and complete renal artery clamping during nephron sparing surgery (NSS) in a porcine model.
Materials and methods: Twelve female farm pigs underwent a laparoscopic nephrectomy. Subsequently, an open partial nephrectomy was performed on the remaining kidney using either total (n = 6, TC) or partial (n = 6, PC) clamping of the renal artery. Real time renal partial oxygen pressure (rPO2) was monitored using a Licox probe (Integra, San Diego, CA). Creatinine levels were measured prior to open partial nephrectomy and on POD #3 and #7. The remaining kidney… More >

Abstract We report a case of a 19-year-old female who presented with right flank pain and microscopic hematuria.Three years earlier, she sustained a stab wound to the right flank and was managed conservatively. After being diagnosed with an enhancing renal mass using computed tomography (CT) scan, duplex ultrasound and angiography were performed revealing an intrarenal pseudoaneurysm. Endovascular coils were successfully employed to selectively embolize the pseudoaneurysm. More >
