Adrenal glands are paired endocrine glands located over the upper renal poles. Adrenal pathologies have various clinical presentations. They can coexist with the hyperfunction of individual cortical zones or the medulla, insufficiency of the adrenal cortex or retained normal hormonal function. The most common adrenal masses are tumors incidentally detected in imaging examinations (ultrasound, tomography, magnetic resonance imaging), referred to as incidentalomas. They include a range of histopathological entities but cortical adenomas without hormonal hyperfunction are the most common...

BACKGROUND: Prolonged renal ischemia during vascular surgery carries high morbidity and mortality. We report an alternative technique for maintaining renal circulation during suprarenal aortic or renal artery clamping. METHODS: Between October 2007 and May 2012, 16 patients undergoing aorto-renal surgery (13 men, 3 women) were operated using temporary axillorenal bypass. Operations were performed for supra- and juxtarenal aortic aneurysms (11), occlusive aortic disease (2), renal artery stenoses (2), and abdominal myofibroblastic tumor (1)...

The co-existence of abdominal aortic aneurysm (AAA) and horseshoe kidney (HSK) is rare. We report a 67-year-old man with an expanding juxtarenal AAA associated with a HSK. The aneurysm had a severely angulated neck and contained a significant amount of mural thrombus. The isthmus of HSK closely lied over the aneurysm, making its exposure extremely difficult. The aneurysm was successfully repaired using transperitoneal approach with division of the renal isthmus and without any need for the renal artery reconstruction...

The clinic experience for surgical treatment of patients, suffering cyst of suprarenal gland (SG), consisted of laparoscopic resection of SG together with a cyst and preserving a visually nonaffected parts of SG, due to what the risk reduction for chronic suprarenal insufficiency of various degree occurrence was achieved. The proposed method was applied in 49 (86.0%) patients of 57, who were operated on for the SG cysts. Intraoperative morbidity, complicated postoperative course and the recurrence occurrence after the SG resection were not observed...

Although the standard treatment of abdominal aortic aneurysm has shifted from open surgery to endovascular repair, open surgery has remained the standard of care for complex aneurysms involving the visceral arteries and in patients unsuitable for endovascular aneurysm repair. Postoperative renal insufficiency may occur after open surgical repair of suprarenal abdominal aortic aneurysm. Methods of minimizing renal ischemic injury include aortic cross-clamping and renal reconstruction techniques. This report describes the use of renal autotransplantation for renal reconstruction during open surgical repair of a suprarenal abdominal aortic aneurysm...

Cholestasis, which is a component of many liver diseases, is often associated with symptoms that resemble clinical adrenal insufficiency. This work aimed to study the histomorphometrical and electron microscopic structure of adrenocorticocytes after surgical induction of bile duct resection (BDR) in adult female albino rats. Sixty rats were randomly divided into control, BDR and sham-operated groups. Six weeks after surgery, the blood serum of the rats was examined biochemically, and the suprarenal cortexes were prepared for histological, morphometrical and statistical studies...

OBJECTIVE: The effect of stent graft fixation type on renal function after endovascular aneurysm repair (EVAR) remains controversial. This systematic review and meta-analysis was conducted to determine whether suprarenal (SR) or infrarenal (IR) fixation influences the risk of renal complications after EVAR. METHODS: We searched MEDLINE and EMBASE with no date or language restrictions for comparative studies evaluating EVAR with SR vs IR fixation on renal dysfunction, renal artery stenosis, renal artery occlusion, renal infarction, and new need for hemodialysis...

Among the most important factors driving morbidity and mortality after aortic surgery is post operative renal insufficiency. The attendant metabolic derangements greatly complicate surgical care, expedite arrhythmias, and can significantly prolong hospital stay and cost. This article seeds to define factors contributory to renal complications after aortic surgery and offers a review of techniques to protect renal mass from post operative declines.

BACKGROUND: Renal insufficiency is the most frequent complication of surgeries that involve suprarenal aortic cross-clamping. Although some studies have assessed the risk of intraoperative renal ischemia by comparing juxtarenal abdominal aortic aneurysms (AAAs) and infrarenal AAAs, a critical limitation is the difference in these patients' clinical backgrounds and aneurysmal features. The present study evaluated the effect of suprarenal aortic clamping by comparing a juxtarenal AAA group with a subgroup of infrarenal AAAs (ie, short and/or large neck)...

The most common presentation of metastases to the pituitary gland in systemic lymphoma is diabetes insipidus resulting from infiltration of the infundibulum/posterior lobe. We describe a 69-year-old man with diffuse large B-cell stage IV lymphoma who presented with anterior pituitary hypofunction, without features of posterior pituitary involvement. He presented with a few months of postural dizziness and hypotension, weight loss, fever, strabismus of right eye and a superficial abdominal wall mass. At this time he had no history of malignancy...

We report the postmortem findings of two siblings with gross and microscopic features consistent with IMAGe association (Intrauterine growth retardation, Metaphyseal dysplasia, Adrenal hypoplasia congenita, and Genital anomalies) with an emphasis on the histopathology of the adrenal gland in this rare syndrome. The first sibling was an 8-week old male diagnosed postnatally with primary adrenal insufficiency. There was no deletion of the DAX1 gene by FISH. Examination at autopsy revealed dysmorphic features including frontal bossing, epicanthal folds, flat philtrum, cryptorchidism, penile chordee, overriding fourth toe, and height and weight below 3rd percentile...

Acute aortic dissection (AAD) is caused by the disruption of intimomedial layer of the aortic walls, which is immediately life-threatening. Although recent studies indicate the importance of proinflammatory response in pathogenesis of AAD, the mechanism to keep the destructive inflammatory response in check is unknown. Here, we report that induction of tenascin-C (TNC) is a stress-evoked protective mechanism against the acute hemodynamic and humoral stress in aorta. Periaortic application of CaCl₂ caused stiffening of abdominal aorta, which augmented the hemodynamic stress and TNC induction in suprarenal aorta by angiotensin II infusion...

Mitochondrial disorder (MtD) is usually a multisystem disease due to impaired mitochondrial energy production. Severe hypokalemia resulting in muscle weakness and rhabdomyolysis has not been reported as a phenotypic feature of MtD. Here we describe a 60-year-old male patient who developed myalgias followed by generalized muscle weakness a few days before admission. Symptoms were attributed to severe hypokalemia that occurred after the patient had discontinued spironolactone, a competitive antagonist of the aldosterone receptor, four months earlier on his own judgment...

BACKGROUND: We report our 11-year experience of juxtarenal aortic aneurysm (JAA) repair with suprarenal aortic cross-clamping. METHODS: We retrospectively reviewed 51 consecutive JAA repairs performed between 2000 and 2010. In all 51 patients, aneurysms were replaced by prosthetic grafts with simple suprarenal aortic cross-clamping. No special renal protective measures (except inter-renal cross-clamping) were performed during interruption of perfusion to kidneys...

UNLABELLED: Endovascular repair of abdominal aortic aneurysm (AAA) allows the exclusion of the dilated aneurismal segment of the aorta from the systematic circulation. The procedure requires, however, that the endograft extends to the healthy parts of the aorta above and below the aneurysm, yet the neck of a juxtarenal aortic aneurysm (JRA) is too short for a standard endovascular repair. Fenestrated endovascular aortic repair (f-EVAR) provides a solution to overcome this problem by enabling the continuation of blood flow to the renal and visceral arteries through holes or 'fenestrations' in the graft...
