Objectives: The Amplatzer Vascular Plug (AVP) is a vascular occlusion device designed to provide optimal embolization in several fields of the endovascular surgery. A full literature review was conducted to analyze AVPs in comparison with coils for the prevention of endoleaks during endovascular abdominal aortic aneurysm repair.

Methods: A systematic review was designed under PRISMA statement guidelines for systematic reviews and meta-analyses. The results were updated with a subsequent electronic search using Medline and Scopus databases up to December 2019.

Results: Eighteen articles making this comparison were found. In 79.7% of the cases, the target vessel was the internal iliac artery; in 1.6%, the common iliac artery; and in 16.7%, the inferior mesenteric artery. Risk of complications (buttock claudication, groin hematoma, endoleaks, and erectile dysfunction) after AVP was low. A cost comparison revealed that the mean cost for coils was around US$2262, while the average cost for the AVP was US$310.

Conclusions: The AVP is an effective and safe device for occluding peripheral vessels, proved to have lower complications rates. Compared with coil embolization, the AVP technique is potentially associated with lower procedural costs.

Ancient schwannoma mimicking a carotid body tumor A case report and review of the literature.

Ann Ital Chir 2020 Jan 20;9. Epub 2020 Jan 20.

Ancient Schwannoma is a type of peripheral neurogenic tumor formed by the Schwann cells presenting mainly as a benign and asymptomatic lesion. The neurilemmoma tumor appears in different sites and, in cases of cervical location, can mimic a carotid body tumor. Herein we describe a clinical case of a 51-year-old woman with latero-cervical swelling. A contrast-enhanced computed tomography scan revealed a classical wineglass image mimicking a carotid body tumor. During surgery the tumor appeared connected to the cervical sympathetic trunk without carotid involvement. The histological exam confirmed the nature of the mass which consisted of an ancient schwannoma. A subsequent systematic review of the literature on ancient schwannoma incidence and treatment confirms it being a benign and rare lesion primarily treatable with open surgery.

Impact of acute cerebral ischemic lesions and their volume on the revascularization outcome of symptomatic carotid stenosis.

J Vasc Surg 2017 02 14;65(2):390-397. Epub 2016 Oct 14.

Background: The influence of acute cerebral ischemic lesions (CILs) on the revascularization outcome of symptomatic carotid stenosis has been scarcely investigated in the literature. This study evaluated the effect of CILs and their volume on the results of carotid revascularization in symptomatic patients.

Methods: All patients with symptomatic carotid artery stenosis who underwent carotid endarterectomy (CEA) or carotid artery stenting (CAS) between 2005 and 2014 were considered. CILs ipsilateral to the stenosis were identified in the preoperative cerebral computed tomography. The volume was quantified in mm and correlated with 30-day rates of stroke and stroke/death by χ, multivariate analysis, Pearson correlation, and receiver operating characteristic curves.

Results: A total of 489 symptomatic patients were treated by CEA (327 [67%]) or CAS (162 [33%]), 186 (38%) ≤2 weeks and 303 (62%) >2 weeks from symptom onset. CEA and CAS patients had statistically similar rates of stroke (3.3% vs 5.5%; P = .27) and stroke/death (3.8% vs 5.9%; P = .22). CILs were identified in 251 patients (53%) and were associated with similar stroke and stroke/death rate compared with patients without CIL (12 [4.8%] vs 8 [3.5%], P = .46; and 14 [5.6%] vs 8 [3.5%]; P = .26, respectively). The median CIL volume was 1000 mm (interquartile range [IQR], 7000 mm). Patients with postoperative stroke and stroke/death had a significantly higher preoperative CIL volume of 5100 mm (IQR, 31,000 mm) vs 1000 mm (IQR, 7000 mm; P = .01) and 4500 mm (IQR, 17,450 mm) vs 1000 mm (IQR, 7000 mm; P = .03), respectively. The receiver operating characteristic curve analysis showed a volume of 4000 mm was predictive of postoperative stroke with 75% sensitivity and 63% specificity. A CIL volume ≥4000 mm was an independent risk factor for postoperative stroke, with a stroke rate of 9.3% (n = 9) vs 1.9% (n = 3) for a CIL volume of <4000 mm (odds ratio, 4.6; 95% confidence interval, 1.1-19.1; P = .03).

Conclusions: CIL volume in symptomatic carotid stenosis seems to influence the 30-day outcome independently from the timing of carotid revascularization. A CIL volume of ≥4000 mm could be considered a significant predictor for postoperative stroke after carotid revascularization.

Plication for the treatment of a radio-cephalic fistula with ulnar artery steal.

Int J Artif Organs 2016 Feb 14;39(2):90-3. Epub 2016 Mar 14.

Department of Vascular Surgery, University of Bologna, Bologna - Italy.

Purpose: Generally the steal syndrome occurs in proximal arterial-venous fistulas and only exceptionally with distal vascular access because of the high number of arteries supplying the hand. We describe a rare case of steal syndrome of a proximalized distal radio-cephalic fistula stealing from both the radial and ulnar artery through the palmar arch.

Methods: An 86 year old man was admitted because of a cyanotic, swollen left hand with trophic lesions at the third finger. He had a latero-terminal radio-cephalic fistula performed in 2006 with subsequent proximalization performed four years later after failure of the first one. Duplex ultrasound examination showed a high flow within the fistula (2080 mL/min) and a retrograde perfusion of the radial artery from the ulnar artery through the palmar arch and an angiography excluded stenosis along the radial artery.

Results: We treated the steal syndrome through a plication technique that was performed with careful flow variations measurement, under duplex evaluation, during the surgical procedure. That procedure was effective to maintain the fistula flow and obtain the symptoms relief. The patient was evaluated the day after the intervention and after 10 weeks. The clinical examination highlighted the resolution of hand ischemia. The Duplex Ultrasound examination showed a lower flow within the fistula (1060 mL/min) and a retrograde perfusion of the radial artery from the ulnar artery through the palmar arch with a three-phase flow. dialysis access from the fistula was never interrupted from immediately after surgery to the present date.

Conclusions: Plication is an effective technique for treatment of steal syndrome requiring a short operative time and it is related to satisfying post-operative results.
