Article Synopsis
- Fibromuscular dysplasia is a leading cause of high blood pressure in young adults under 40, and renal artery angioplasty often helps normalize blood pressure.
- Two cases are discussed where patients with hypertension due to renal artery stenosis faced challenges: one had a relapse of stenosis after angioplasty, while the other couldn't undergo the procedure at all.
- Both patients ultimately received successful renal autotransplantations that resolved their high blood pressure, with the article also detailing relevant background and outcomes related to this surgical option.
Purpose: To evaluate the long-term clinical efficacy of the Tigris © stent (Gore ©) in femoropopliteal chronic total occlusions (CTOs).
Material And Methods: This single centre retrospective study included 29 patients treated with 47 Tigris© stents for CTOs. Lesion location, type, length, revascularisation method, smoking status and diabetes were reviewed.
Introduction: Superior mesenteric arteriovenous fistulae (SMAVF) are rare, usually secondary to trauma or iatrogenic injury and typically present sometime after the initial insult.
Report: A 30 year old male underwent immediate laparotomy for abdominal gunshot injury. The small bowel mesentery contained a large haematoma and a palpable thrill.
Background Dedicated blood-pool contrast agents combined with optimal angiographic protocols could improve the diagnostic accuracy of thoracic magnetic resonance angiography (MRA). Purpose To assess the clinical utility of Gadofesveset-enhanced imaging and compare an optimized steady-state (SS) sequence against conventional first-pass dynamic multi-phase (DMP) imaging. Material and Methods Twenty-nine patients (17 men, 12 women; mean age = 42.

Methods: A cohort of 20 patients undergoing perfusion CT imaging of the liver was examined. Dynamic images of the liver were reformatted into contiguous thin slices.
Ultrasound-assisted thrombolysis of an occluded transjugular portosystemic shunt.

February 2018
Transjugular intrahepatic portosystemic shunt (TIPS) insertion is commonly performed for refractory ascites or variceal bleeding. However, TIPS dysfunction can be seen in both early and late settings, with shunt thrombosis a particular problem. Treatment of shunt dysfunction commonly involves angioplasty and re-lining, with or without embolectomy, mechanical thrombectomy, or thrombolysis.

Materials And Methods: We retrospectively reviewed 1485 of femoropopliteal angioplasties that were performed in our centre in a 4-year period and analysed 12 cases (<1%) where distal embolization that required further intervention occurred.
