“…7 Additionally, Osler-Weber-Rendu syndrome (hereditary hemorrhagic telangiectasia) is associated with renal AVM, which is an inherited disorder characterized by malformations of various blood vessels (vascular dysplasia), potentially resulting in bleeding (hemorrhaging) and shunting of blood. 8 Renal AVM need to be differentiated from malignant lesions of the kidney. On ultrasound, renal AVMs appear as a hypoechoic focus within the renal parenchyma.…”

Renal arteriovenous malformations (AVMs) although uncommon are the most underrecognized cause of recurrent haematuria especially in young patients. Although renal AVMs are commonly incidentally detected, life threatening complications such as gross haematuria and AVM rupture have been implicated. Ultrasound is the first line imaging investigation which has a crucial role in treatment planning, post‐procedural, long‐term follow‐up, and assessment of complications associated with renal AVMs. This is a report of a rare case of spontaneous renal AVM in a patient without prior history of renal biopsy or previous trauma. A 26‐year‐old male presented for an ultrasound with recurrent haematuria. This case report highlights the role of ultrasound in the diagnosis, follow‐up and assessment of treatment related complications of renal AVMs.

“…From our point of view, the modality of choice in patients with high blood flow velocity and/or wide diameter of AVF is open surgery. 8 , 9 Previously, in the case of renal arteriovenous aneurysm rupture (the complication we faced in the left-sided aneurysm), nephrectomy was a life-saving procedure. 10 An ex vivo approach seems an appropriate alternative to nephrectomy.…”

Renal arteriovenous fistulas are pathologic communications between the renal arteries and veins without interconnecting capillaries. Reports on the combination of fibromuscular dysplasia, aneurysms, and renal arteriovenous fistula are extremely rare in the literature. In the case of renal arteriovenous aneurysm rupture, urgent nephrectomy was the only life-saving procedure reported. The ex vivo approach seems to be an appropriate alternative to nephrectomy. This article presents a case of successful treatment of bilateral fibromuscular dysplasia with aneurysm and arteriovenous fistulas complicated by renal artery aneurysm rupture.

“…Intraocular vascular lesions, including retinal telangiectasia, arteriovenous malformation in the retina, and abnormal choroidal vascular changes were reported [13–17]. Sudden visual loss has been described because of ocular involvement [17], bleeding from kidney and urinary vascular malformations are other complications reported in HHT patients [18, 19]. Here, the Eng-related hereditary haemorrhagic telangiectasia, HHT-1, is investigated.…”

Hereditary Hemorrhagic Telangiectasia-1 (HHT-1) is a vascular disease caused by mutations in the endoglin (Eng)/CD105 gene. The objective of this study was to quantify the oxidative state of a rodent model of HHT-1 using an optical imaging technique. We used a cryofluorescence imaging instrument to quantitatively assess tissue metabolism in this model. Mitochondrial redox ratio (FAD/NADH), FAD RR, was used as a quantitative marker of the metabolic status and was examined in the kidneys, and eyes of wild-type and Eng +/− mice. Kidneys and eyes from wild-type P21, 6W, and 10M old mice showed, respectively, a 9% (±2), 24% (±0.4), 15% (±1), and 23% (±4), 33% (±0.6), and 30% (±2) change in the mean FAD RR compared to Eng +/−mice at the same age. Thus, endoglin haploinsufficiency is associated with less oxidative stress in various organs and mitigation of angiogenesis. Images of FAD for one representative eye (10 months, Eng+/−). Left: volume rendering of half of the eye (with connected optic nerve) including the lens. Right: volume rendering of the eye excluding the lens.
