Sac enlargement due to seroma after endovascular abdominal aortic aneurysm repair with the Endologix PowerLink device

A patient who had undergone endovascular repair of an abdominal aortic aneurysm with the Endologix PowerLink bifurcated system presented with delayed aortic aneurysm enlargement due to assumed endotension. He was treated with aortic sac evacuation and wrapping of the endograft. This is the first report of endotension and aneurysm sac enlargement after implantation of the PowerLink endograft

Endovascular Treatment of Thoracic Aortic Floating Thrombus in Patients Presenting with Acute Lower Limb Ischemia

We report two cases of descending thoracic aorta floating thrombus treated with Bolton Relay thoracic free-flow stent graft. The patients had symptoms of lower limb ischemia; they underwent preoperative angiography and CTscan, then we proceeded with endovascular exclusion of the thrombus from the systemic circulation. At 12 months, the graft was still patent in both patients, without any signs of endoleak

Venous thromboembolism and chronic venous disease among people who inject drugs: A systematic review and meta-analysis

Introduction Intravenous drug use continues to pose a substantial burden worldwide and little is known about the risk of venous thromboembolism (VTE) and its sequelae in people who inject drugs (PWID). Methods A systematic literature search was conducted on the prevalence of VTE and chronic venous disease in intravenous drug users, as well as on the prevalence of intravenous drug use among selected VTE patients. Two reviewers independently selected the articles and appraised their quality. A random-effect meta-analysis was performed to pool risks across studies. Results We included 18 studies with a total of 7691 patients. The overall prevalence of VTE among PWID was 29% (95%CI: 19–40%). Among patients diagnosed with VTE, 15% (95%CI: 10–20%) were PWID. Similar rates were confirmed in more recent studies published in the past decade, although these studies are often based on the general population from higher-risk areas. Reported rates of chronic venous disease ranged between 58% and 61%. The majority of the included studies had a low to moderate quality of evidence. We could not exclude a selection bias in the studies in geographical regions with high intravenous drug use prevalence. Conclusion VTE and chronic venous disease appear to be common and understudied complications of injective drug use. National programs for PWID patients should also focus on early and late VTE-associated complications

Endovascular treatment of iatrogenic axillary artery pseudoaneurysm under echographic control: A case report

Aim: Brief case report of the treatment of a large axillary artery pseudoaneurysm after a pacemaker using a left brachial cutdown and a retrograde delivery of a covered stent using ultrasound and fluoroscopic guidance. The patient's renal function precluded the use of contrast materials.Case Report: A 77 years old man presenting with acute renal failure and haemoglobin decrease arrived with an expanding pseudoaneurysm of the left axillary artery from a pacemaker placement. Considering the site of the lesion and patient's comorbidities, under echographic control, a Hemobahn \uae stent-graft was placed; fluoroscopy assisted manipulation of guidewires and sheaths into the aortic arch. The procedure was successfully ended without any complications. At 8 months the stent graft was still patent.Conclusion: Ultrasound guidance may represent an alternative for pseudo-aneurysm exclusion without any use of contrast medium, especially in those patient where lesions are easily detectable using ultrasonography and when comorbidities contraindicate aggressive surgical or angiographic approach

Midterm results of proximal aneurysm sealing with the ovation stent-graft according to On-vs off-label use

Purpose: To compare the use of the Ovation stent-graft according to the â\u89¥7-mm neck length specified by the original instructions for use (IFU) vs those treated off-label (OL) for necks 2 mm). Results: At 3 years, there was no aneurysm-related death, rupture, stent-graft migration, or neck enlargement. There were no differences in terms of freedom from type Ia endoleak (98.2% IFU vs 96.8% OL, p=0.6; hazard ratio [HR] 0.55, 95% CI 0.02 to 9.71 or freedom from any device-related reintervention (92.8% IFU vs 96.4% OL, p=0.4; HR 2.42, 95% CI 0.34 to 12.99). In the sealing zone, the mean change in diameters was-0.05±0.8 mm in the IFU group and -0.1±0.5 mm in the OL group. Conclusion: Use of the Ovation stent-graft in patients with neck length <7 mm achieved midterm outcomes similar to patients with â\u89¥7-mm-long necks. These midterm data show that the use of the Ovation system for the treatment of infrarenal abdominal aortic aneurysm is not restricted by the conventional measurement of aortic neck length, affirming the recent Food and Drug Administration-approved changes to the IFU

Delayed endovascular treatment of descending aorta stent graft collapse in a patient treated for post- traumatic aortic rupture: a case report

Background: We report a case of delayed endovascular correction of graft collapse occurred after emergent Thoracic Endovascular Aortic Repair (TEVAR) for traumatic aortic isthmus rupture.Case presentation: In 7 th post-operative day after emergent TEVAR for traumatic aortic isthmus rupture (Gore TAG \uae 28-150), a partial collapse of the endoprosthesis at the descending tract occurred, with no signs of visceral ischemia. Considering patient's clinical conditions, the graft collapse wasn't treated at that time. When general conditions allowed reintervention, the patient refused any new treatment, so he was discharged.Four months later the patient complainted for severe gluteal and sural claudication, erectile disfunction and abdominal angina; endovascular correction was performed. At 18 months the graft was still patent.Discussion and Conclusion: Graft collapse after TEVAR is a rare event, which should be detected and treated as soon as possible. Delayed correction of this complication can be lethal due to the risk of visceral ischemia and limbs loss
