An Autopsy Case of Saphenous Vein Graft Rupture.

Saphenous vein graft aneurysms are rare complications after coronary artery bypass grafting that carry serious complications. Less than 10 case reports of autopsy findings consistent with ruptured saphenous vein grafts exist in the literature. We report a case of a female presenting at autopsy who, after coronary artery bypass grafting 20 years prior, demonstrated findings of a saphenous vein graft aneurysm and rupture. With limited evidence from medical records, this case highlights a need for patients with previous coronary artery bypass grafting to be properly monitored to detect minute graft changes before aneurysm formation and rupture as seen in our decedent.

Risk factors associated with saphenous vein graft aneurysm after coronary artery bypass graft

Introduction: Saphenous vein graft aneurysm (SVGA) is a rare but life-threatening complication following coronary artery bypass grafting (CABG). The authors aim to identify the potential risk factors that lead to SVGA in post-CABG patients. Methods: A systematic review of original studies, observational studies, systematic reviews, meta-analyses, case studies, and case series was conducted using PubMed, Web of Science, Scopus, EMBASE, and Google Scholar involving adult patients (>18) with SVGA after CABG using MESH terminology in a broad search strategy. All searches were performed and analyzed according to PRISMA and duplicates were removed via Rayyan. Two independent investigators extracted and assessed the data involving demographics, and baseline data related to CABG and its manifestations. Results: Out of 487 finalized articles, 14 of them matched the inclusion requirements and reported 12 cases of SVGAs following CABG. Atherosclerosis with intimal calcification was the most common risk factor followed by infection. Others included hyperlipidemia, pneumonia, and cardiac pathologies mostly related to the ventricles and valves. Conclusion: Atherosclerosis associated with intimal calcification is the most common risk factor. Patient outcomes seem to improve upon early identification and regular follow-up imaging. The exclusion criteria indicated the study’s limits, and future studies that address these constraints may be able to better understand the risk variables involved in the genesis of SVGA.

Early Saphenous Vein Graft Aneurysm Rupture: A Not So-Late Complication. Case Report and Comprehensive Literature Review.

Saphenous vein graft (SVG) is a cardiac surgical practice used to create a cardiac bypass in cases of coronary artery obstruction. It consists of a surgical procedure that involves the creation of an aorto-coronary communication by a venous conduit (saphenous vein) to bypass coronary stenosis and allow cardiac revascularization. This practice can be affected by early and late complications. The most feared complication is graft aneurysm or pseudoaneurysm degeneration and rupture which are considered late complications. This paper presents a rare case of SVG aneurysmal rupture that occurred 24 h after surgery and a review of the literature to provide a general look at the state of knowledge. The systematic review was carried out using the guidelines according to the PRISMA method. Cases of aneurysmal rupture have never been described prior to one month after surgery. The male sex and subjects under 45 are the most affected by this complication. Death occurs in less than half of the cases, being more frequent in young people. Performing a CT or angio-CT examination led to the diagnosis. It is impossible to estimate the implanted vessel's quality, so postoperative follow-up is fundamental. Transesophageal ultrasound can be useful, and hematochemical tests are valuable early diagnostic tools, whrease CT and angio-CT can be useful even months after surgery. Forensic analysis should always perform an autopsy and graft histological examination.

Aneurısmas arterıales de extremıdad superıor: etıología, manejo y resultado

Upper extremity arterial aneurysms are not common clinical conditions. It may causes ischemic gangrene or limb losses as a result of thromboembolic events due to endothelial damage. In this study, we aimed to investigate the etiology, management, and long-term outcome. A total of 55 upper extremity aneurysms between January 2009 and April 2018 were retrospectively investigated. The mean age was 41 ± 13 years, and the women and men were 13 (23.6%) and 42 (76.4%). The mean follow-up was 43 ± 18 months. The incidence of pseudoaneurysm was higher than the true aneurysm (64.5% vs. 35.5%). 30 (84%) patients who had pseudoaneurysm repaired primerely and 6 (16%) patients had patchplasty. About 58% of the true aneurysm caused by blunt trauma. 4 (21%) true brachial aneurysm patients were required emergency intervention due to distal ischemia. 16 (84.2%) patients operated using by saphenous vein graft. The primary and secondary patency was 87.5% and 93.8%. No limb or life loss occurred during follow-up. Pseudoaneurysms are more common among upper limb aneurysms and they occur mostly by iatrogenic causes. Blunt trauma can be main cause of the true aneurysm. Surgical resection of the aneurysm and interposition of saphenous vein graft provides excellent results in the long-term.

Chronic Limb Ischemia due to Thrombosis of an Aneurysmal Degeneration of the Autogenous Vein Graft: A Case Report.

Nonanastomotic aneurysmal degeneration of a great saphenous vein graft is an unusual condition, despite the common use of this conduit in arterial reconstructions. Vein grafts are at risk of degenerative changes, but the real cause remains unknown. Postoperative graft surveillance with duplex ultrasound scanning is important for maintaining patency of the venous graft. We present a rare case of chronic limb ischemia due to partial thrombosis of an aneurysm of the great saphenous vein graft.

Longitudinal computational fluid dynamics study of stenosis and aneurysmal degeneration of an aortorenal bypass.

Saphenous vein graft (SVG) bypass placement is regarded as the optimal option for renal artery stenosis, which usually causes secondary hypertension and poor renal perfusion. Using computational fluid dynamics, this study aimed to investigate the underlying hemodynamic mechanism of the vein aneurysm and stenosis after aortorenal bypass surgery. Three-dimensional models were reconstructed based on computed tomographic angiography images of a 20-year-old female patient who suffered from uncontrollable hypertension using the image processing package Mimics (Materialise). The morphology and hemodynamic parameters in the healthy state, at initial presentation and at post-operative 9-month and 2-year follow-ups after surgery were analysed. The hemodynamic parameters became normal in the left and right renal arteries after bypass surgery. However, flow separation and stagnation occurred at the post-operative 9-month aorta-vein anastomosis, which caused asymmetrical flow and extremely high wall shear stress (WSS) and WSS gradients at the outflow vein tract, where the stenosis occurred 2years later. In addition, the graft bending produced an asymmetrical flow pattern downstream. This research revealed that the abnormal hemodynamics, including flow separation and extremely high WSS values and gradients, caused by the retrograde flow of aortorenal bypass may be responsible for the SVG degeneration. In addition, flow asymmetry due to vessel bending is a potential risk factor for SVG aneurysm dilation.
