“…1 RAO can occur unnoticed and may, like renal artery stenosis (RAS), present itself clinically as a cause of arterial hypertension. 1 Historically, surgical revascularisation has been the standard therapy for RAO 2,3 or RAS in a solitary kidney. 4 Currently established treatments of RAO are either open surgery or conservative follow-up with medical antihypertensive therapy, whereas percutaneous transluminal renal angioplasty (PTRA) is an established treatment of RAS.…”

We retrospectively evaluated short-and long-term effects of percutaneous transluminal renal angioplasty (PTRA) with or without stent placement of renal artery occlusion (RAO) upon blood pressure (BP), serum (s)-creatinine, and the need for antihypertensive treatment in 34 RAO patients who underwent PTRA during 1996-2002. In 24/34 (71%) treatment was considered technically successful, 22/24 (92%) were treated with PTRA þ stent, two with only PTRA. Patients were followed for mean 2.6 (range 0-8) years, during which 14/34 (41%) patients died. In all 34 patients, systolic and diastolic BP (SBP and DBP) before treatment were 184730/95715 mmHg and had decreased at discharge (to 157721/80710 mmHg; Po0.001 for both SBP and DBP), and remained lower after 1 year (154720/ 8377 mmHg;Po0.001 for SBP and Po0.01 for DBP), and at last follow-up (148720/80712 mmHg; Po0.001 for both SBP and DBP). No changes occurred in s-creatinine or the number of antihypertensive drugs. Similar results were seen in the subgroup of 24/34 (71%) patients in whom treatment was technically successful. Among the 24 patients undergoing technically successful PTRA, absence of nephrosclerosis (P ¼ 0.035) and a shorter duration of hypertension (P ¼ 0.020) predicted favourable clinical outcome. No adverse effects upon s-creatinine or the need for antihypertensive medication were seen in patients in whom treatment was considered a technical failure. Seven of these patients were treated with PTRA of another renal artery than the occluded, or with embolisation. In conclusion, RAO can be treated with endovascular techniques. Technically successful results with decreasing blood pressure levels were obtained in 71% of patients.

“…In group 4 the glomeruli were damaged with loss of glomerular contents, there was also the presence of arteries with minor occlusion. Renal artery occlusion (RAO) is a rare but significant cause of kidney loss which may be caused by renal artery thrombosis [36] . Group 5 showed minor atrophy of the glomerular tuft with slight distention of the bowman's space.…”

Abstract:The presence of essential amino acids in meat makes it a complete protein, this makes meat a highly sort after source of protein in the human diet. The World's demand for animal-derived protein has been projected to double by 2050. As a result there is a resultant increase in livestock industries to meet this demand. While meat is generally consumed as a source of protein, processed cattle hide popularly known as -Kanda" in southeastern Nigeria is consumed as a substitute for meat though it may not necessarily provide the same level of nutritional value with meat. The method of processing this food delicacy (Kanda) by singeing with scrap tyre or firewood has opened the door for heavy metal and or polycyclic aromatic hydrocarbon (PAHs) contamination, thereby putting unsuspecting consumers at health risk. This study therefore investigated the effects of consuming scrap tyre-singed cattle hide and firewood singed cattle hide on the kidney, liver and heart of male Wistar rats. Consuming singed cattle hides significantly elevated some serum marker enzymes important in kidney, liver and heart damage i.e alanine and aspartate aminotransferases, alkaline phosphatase, creatine kinase, and lactate dehydrogenase, with the groups that were fed with the hide singed with scrap tyre showing severe elevations. Consuming the singed Kanda also significantly decreased the serum concentrations of K + , Na + , Cl -, and significantly increased HCO 3 and urea concentration. An examination of the organ tissues also 4 revealed serious morphological changes. In conclusion, consuming singed Kanda had detrimental effects on the vital organs studied.

“…25 This has prompted some authors to suggest that blood flow should be reestablished regardless of the time frame. 26 There is no consensus regarding this issue, and the exact role of intraarterial thrombolysis in RAE is yet to be determined.…”

Renal Artery Embolism

et al. 2008

View full text Add to dashboard Cite

Renal artery embolism was first described in 1940, but it is only recently becoming recognized as a clinically significant entity. Although relatively uncommon, it is clearly responsible for considerable morbidity in patients who experience it. The pathogenesis is typically related to cardiac thrombus formation with subsequent embolization, although other etiologies have been described. The authors present a case report followed by a review of the literature to highlight the clinical characteristics of this phenomena. Presentation, diagnostics, and treatment options will be reviewed with the aim of increasing awareness of renal artery embolism. As clinicians become more familiar with this condition, they will be more likely to consider it as a possible diagnosis in patients with a typical presentation. This will hopefully lead to improved care through prompt diagnosis and treatment, particularly as one treatment option may be time sensitive.
