“…Definitive treatment is required in patients who have symptomatic AVM. Patients with persistent haematuria, massive haematuria or frank AVM rupture require therapeutic intervention 8 9. As in our study the patient had persistent frank haematuria so we decided to undergo embolisation of the vessel.…”

Renal arteriovenous malformation: an unusual cause of recurrent haematuria

2013

A 54-year-old woman presented with gross painless haematuria. Initial workup showed no abnormality except mild hydronephrosis on CT scan. Cystoscopy and retrograde pyelography did not find any gross lesion and her urine cytology was also negative. She had recurrent haematuria so her CT was reviewed with the radiologist with clinical suspicion of arteriovenous malformation (AVM) which was suggested by relatively increased contrast density in the hemiazygous vein and renal vein in the arterial phase. She underwent angioembiolisation of left renal AVM after which her haematuria settled.

“…No evidence in the literature currently compares medical treatment to therapeutic interventions. There are, however, reports of patients being medically managed and obtaining control of their secondary hypertension without any invasive intervention [10]. However, patients are more likely to achieve control of their hypertension with interventional therapy.…”

Congenital Renal Arteriovenous Malformation: A Rare but Treatable Cause of Hypertension

Patient: Female, 29 Final Diagnosis: Renal arteriovenous malformation Symptoms: Hypertension Medication: — Clinical Procedure: Angiography Specialty: Cardiology Objective: Rare disease Background: Congenital renal vascular anomalies have been classified into 3 categories: cirsoid, angiomatous, and aneurysmal. These classifications are based on the size, location, and number of vessels involved. Aneurysmal malformations, such as the one reported here, have a single (and dilated) feeding and draining vessel. The prevalence of renal AVMs is estimated at less than 0.04%, making them rare causes of secondary hypertension. Case Report: A 29-year-old white woman was seen in the hypertension clinic as a referral from high-risk obstetric clinic for management of hypertension (HTN). A secondary hypertension workup with Doppler waveforms of the renal arteries revealed prominent diastolic flow in the left compared to the right. For confirmation, an MRA was done, which showed a large left renal upper-pole arteriovenous malformation (AVM) with associated vascular shunting and early opacification of the left renal vein. This congenital AVM was identified as the cause of her hypertension. Angiography and coil embolization were performed. The patient’s BP normalized within a few days and she was taken off her antihypertensive medications. Conclusions: This case illustrates that a careful review of duplex waveforms beyond just peak velocity and ratios is important to identify uncommon pathologies. This is important, as renal AVMs respond well to embolization, with resolution of hypertension in 59% of patients treated.

“…However, balloon embolization require large sheaths and embolization can occur if there is premature balloon deflation. Coil embolization techniques are now the most widely used approach to occlude AVF, because it is more convenient and is associated with less complications than balloon embolizaion 16). However, it has been reported that only five cases of ACF have been performed successfully using coil embolization 13)15)17)18).…”

Iatrogenic Left Internal Mammary Artery to Great Cardiac Vein Anastomosis Treated With Coil Embolization

et al. 2011

View full text Add to dashboard Cite

Inadvertent left internal mammary artery (LIMA)-great cardiac vein (GCV) anastomosis is a rare complication of coronary artery bypass graft surgery. Patients with iatrogenic aortocoronary fistula (ACF) were usually treated surgical repair, percutaneous embolic occlusion with coil or balloon. We report a case of iatrogenic LIMA to GCV anastomosis successfully treated with coil embolization and protected left main coronary intervention through the percutaneous transfemoral approach.
