Bilateral Congenital Pelvic Arteriovenous Malformation: A Case Report and Review of Literature.

Purpose: Through a paradigmatic case and a systematic literature review, we present various endovascular strategies for treating pelvic paravesical arteriovenous vascular malformations (AVMs), with a focus on the efficacy of accessing the shunt point through direct puncture of the venous collector.

Case Report: A 42-year-old male with nonspecific pelvic pain underwent a computed tomography (CT) scan, which revealed bilateral pelvic AVMs characterized by a network of arteriolar afferents originating from the internal iliac arteries and the inferior mesenteric artery, draining into 2 interconnected giant venous sacs in the bilateral paravesical space. The malformation was classified as type II according to the Cho classification.

Endovascular revascularization of critical limb ischemia: the role of ultrasound-guided popliteal sciatic nerve block for the procedural pain management.

Objectives: To evaluate the impact of the ultrasound-guided popliteal sciatic nerve block (PSNB) for pain management during endovascular treatment of chronic limb-threatening ischemia (CLTI).

Material And Methods: From November 2020 to January 2022, 111 CLTI patients that underwent endovascular procedures were prospectively enrolled in this prospective single-arm interventional study. Ultrasound-guided PSNB was used for procedural pain control.

Successful endovascular thrombectomy with the ClotTriever System for acute subclavian vein thrombosis in venous thoracic outlet syndrome.

Background: The case describes a successful endovascular thrombectomy using the ClotTriever System for an acute subclavian thrombosis in venous thoracic outlet syndrome. To the best of our knowledge, this is the first case report on use of Inari ClotTriever for acute upper extremity deep venous thrombosis due to venous thoracic outlet syndrome. The rapid technical and clinical success of our intervention may be an interesting cue for interventional radiologist colleagues.

Stent-Assisted Coil Embolization of a Saccular Visceral Aortic Aneurysm: Case Report and Review of the Literature.

Purpose: We present the results of unconventional endovascular treatment of a voluminous (65 mm) saccular visceral aortic aneurysm in a 78-year-old woman. Patient was deemed unfit for open surgery due to comorbidities. Fenestrated or branched endografting was also excluded due to the small diameter of the aorta, the severe stenosis at the origin of celiac trunk, and the anomalous origin of superior mesenteric artery arising infrarenally.

Percutaneous closure of accidentally subclavian artery catheterization: time to change first line approach?

Purpose: To present our experience and provide a literature review dissertation about the use of a suture-mediated percutaneous closure device (Perclose Proglide -PP- Abbott Vascular Inc., Santa Clara, CA, USA) to achieve hemostasis for unintended subclavian arterial catheterization during central venous line placement.

Materials & Methods: Since October 2020, we have successfully treated four consecutive patients with a central venous catheter (8 to 12 French) in the subclavian artery.

Emergency management of iatrogenic arterial injuries with a low-profile balloon-expandable stent-graft: Preliminary results.

Endovascular treatment of arterial injuries with stent-graft is a reliable alternative approach in patients not suitable for embolization or at high risk for surgery. The aim of our study was to evaluate the efficacy and the safety of the BeGraft stent-graft, a low-profile balloon expandable covered stent, for emergency endovascular treatment of iatrogenic arterial injuries.Between August 2015 and September 2018, 34 consecutive patients (mean age 71 ± 12 years, 9 females) underwent implantation of BeGraft stent-grafts for iatrogenic arterial injuries (22 active bleedings, 11 pseudoaneurysms, and 1 enteric-iliac fistula).

Radiation dose during endovascular aneurysm repair (EVAR): upgrade of an angiographic system from standard to Eco mode.

Purpose: To evaluate the radiation dose reduction during endovascular aneurysm repair (EVAR) after the reconfiguration of a Philips AlluraXper FD20 X-ray system.

Methods: Between 2013 and 2015, we implemented a low-dose protocol (Eco dose) increasing the filtration with 1 mm of Al and 0.1 of Cu on both fluoroscopy and fluorography and halving the frames per second in fluoroscopy.

Incidence of hepatic encephalopathy after transjugular intrahepatic portosystemic shunt (TIPS) according to its severity and temporal grading classification.

Objectives: To evaluate hepatic encephalopathy (HE) incidence after transjugular intrahepatic portosystemic shunt (TIPS) and classify by gravity and frequency.

Methods: This is a retrospective study of 75 patients with no previous episodes of HE who underwent TIPS between 2008 and 2014 with clinical follow-up after 6 and 12 months. Patient risk factors evaluated include age, INR (international normalized ratio), creatinine, bilirubin, and MELD score (Model for End-of-stage Liver Disease).

Percutaneous segmental dilatation of portal stenosis after paediatric liver transplantation to avoid or postpone surgery: two cases and literature review.

Purpose: The authors retrospectively reviewed the results obtained with percutaneous treatment of portal stenosis.

Materials And Methods: In November 2005 and March 2008, two patients, 15 and 32 months old, underwent portal vein angioplasty at our centre. Both procedures were performed after ultrasound-guided portal vein puncture and measurement of pre- and postanastomotic pressure gradients.
