Primary femoral aneurysms are uncommon and are frequently associated with other aneurysms, particularly those of the aorta and popliteal arteries. True isolated atherosclerotic aneurysm of the superficial femoral artery is a rare pathology [2].. Rigdon et al discussed 17 "arteriosclerotic" superficial femoral artery aneurysms in 14 patients, which revealed complication at presentation in 65% - rupture in 35%, thrombosis in 18%, and distal emboli in 12%. However, limb salvage was 94% and there were no perioperative deaths [3]. Males (75%) were more common than females, and the average age was 77 years (range 61 to 93) [3].. True femoral artery aneurysms are attributed to weakening of the arterial wall due to atherosclerosis. True femoral artery aneurysms are relatively rare and are found in elderly men who have strong smoking history. Aortic aneurysms are approximately 10 times more common. According to Levi et al distal embolization occurs in 0-26% of cases, acute thrombosis occurs in around 15% ...
True pulmonary artery aneurysms are rare. Deterling and Clagett reported only eight cases in a review of 109 571 necropsies.2 Aggressive surgical approaches have often been advocated based on previous reports of dissection or rupture. Pulmonary artery aneurysms, even when very large, in the presence of low pulmonary pressures and the absence of left to right congenital or acquired shunts, may not pose such a risk in sharp contrast with those with pulmonary hypertension or Eisenmengers syndrome.3,4 Patients in this series all had low pulmonary arterial pressures, no significant congenital or acquired left to right shunts, and giant pulmonary artery aneurysms involving the main or proximal branch pulmonary arteries. They survived to a median age of 52 years without evidence of intimal tear or medial dissection and presented because of right ventricular dysfunction secondary to pulmonary regurgitation.. True aneurysms involve all components of the vessel wall.5 There may be associated intrinsic ...
Abstract The rarity of saphenous vein graft aneurysms following coronary artery bypass graft surgery presents an interesting case, as seen in a 72 year-old gentleman who underwent his third bypass surgery for an aneurysmal graft. Information regarding the case was gathered using the Lehigh Valley Health Network medical databases. The 8 cm aneurysmal portion of the graft was resected successfully and replaced with a CryoVein. Following surgery the patient had relief of symptoms and recovered well. It was determined that the patient had two true aneurysms present, making surgery a necessity in this specific case. Introduction Saphenous vein graft (SVG) aneurysms following coronary artery bypass grafting (CABG) are rare but fatal complications that frequently require surgical repair.1 We address a rare surgical case regarding an individual requiring a third sternotomy involving two SVG aneurysms with thrombus, 22 years following CABG. Information was gathered retrospectively using the LVHN database. Case

It is often asymptomatic, while the first presentation could be severe hemoptysis or death. Surgical intervention needs to be planned carefully with a multidisciplinary team approach to secure optimal outcome. We hope to spread our experience with such cases and to encourage other surgeons worldwide to deal surgically with these cases when its indicated.CASE PRESENTATION: A 47 years old man presented to our institution after three episodes of hemoptysis, echo demonstrated good left ventricle (LV) systolic function, normal right ventricle (RV) size and ...
The limited number of patients with identified Hughes-Stovin syndrome has precluded the initiation of controlled studies of the management of patients with pulmonary arterial aneurysms [3]. Corticosteroids, alone or in combination with an immunosuppressant, are generally considered first-line therapy [4]. Surgical resection has been the traditional treatment of choice when the risk of lethal hemoptysis necessitates more definitive therapy. Total pneumonectomy or lobectomy has been performed with some successful results [5].. The high morbidity associated with surgery and the frequent bilaterality and multifocality of the pulmonary artery aneurysms make transcatheter embolization an attractive alternative to surgery in most cases. To our knowledge, few patients with Hughes-Stovin syndrome have been treated by performing embolization of a pulmonary arterial aneurysm with the use of several agents, including steel coils, Ethibloc, and isobutyl cyanoacrylate, an epoxy [4, 6, 7].. This is the first ...

2018 The Authors Introduction: The case of an idiopathic thrombosed popliteal aneurysm is described in an otherwise healthy 6 year old child. This is the fourth reported case and the second youngest patient to present with an idiopathic isolated popliteal aneurysm. Report: A 6 year old boy presented with an acutely ischaemic right foot. Computed tomography angiography confirmed a thrombosed popliteal aneurysm. A femoropopliteal bypass was performed with reversed long saphenous vein and ligation of the aneurysm. Yearly follow up is ongoing with ultrasound surveillance; the childs growth and development is unaffected, and the graft is patent. There was a readmission over six years later with claudication on the right side. There was evidence of thrombus in the graft with associated distal embolisation, which was managed conservatively with anticoagulation. Discussion: Given the rarity of such presentations in the paediatric population, there is minimal good quality data to guide treatment. There ...
The shape of an aneurysm is described as being fusiform or saccular which helps to identify a true aneurysm. A true aneurysm involves all three layers of the arterial blood vessel wall. The more common fusiform-shaped aneurysm bulges or balloons out on all sides of the aorta. A saccular-shaped aneurysm bulges or balloons out only on one side.. The aorta is under constant pressure from blood being ejected from the heart. With each heartbeat, the walls of the aorta expand and spring back, exerting continual pressure or stress on the already weakened aneurysm wall. Therefore, there is a potential for rupture (bursting) or dissection (separation of the layers of the thoracic aortic wall), which may cause life-threatening hemorrhage (uncontrolled bleeding) and, potentially, death.. Once formed, an aneurysm will gradually increase in size and there will be a progressive weakening of the aneurysm wall. Treatment for a thoracic aneurysm may include surgical repair or removal of the aneurysm to prevent ...

Doctor answers on Symptoms, Diagnosis, Treatment, and More: Dr. Colantino on what does it mean to have a popliteal aneurysm rupture: An aneurysm is an dilitation of a blood vessel. This is the result of weakening in the wall of the artery. The weakened wall can rupture, and bleeding into the tissues around the knee occurs, causing tremendous pain and swelling. The blood outside the artery can then impinge on flow to the lower leg and foot, causing ischemia. In all, very bad, and one of the reasons to fix aneurysms electively. for topic: What Does It Mean To Have A Popliteal Aneurysm Rupture
WHAT THIS STUDY ADDS Previous comparisons between open and endovascular repair of popliteal aneurysms have focused on asymptomatic patients, and have short follow up. This study is strengthened by the fact that it is contemporary, population based, without any selection bias, reporting on all kinds of presentations, and has approximately 90% 1 year follow up data. It shows that endovascular repair has significantly inferior results compared with open repair, in particular in the group of patients who present with acute ischaemia. We believe these results will make many vascular surgeons think twice before they treat patients endovascularly in the future. Background: Popliteal aneurysm (PA) is traditionally treated by open repair (OR). Endovascular repair (ER) has become more common. The aim was to describe time trends and compare results (OR/ER). Methods: The Swedish vascular registry, Swedvasc, has a specific PA module. Data were collected (2008-2012) and supplemented with a specific protocol ...
Charcot-Bouchard aneurysms (also known as miliary aneurysms or microaneurysms) are aneurysms of the brain vasculature which occur in small blood vessels (less than 300 micrometre diameter). Charcot-Bouchard aneurysms are most often located in the lenticulostriate vessels of the basal ganglia and are associated with chronic hypertension. Charcot-Bouchard aneurysms are a common cause of cerebral hemorrhage. If a Charcot-Bouchard aneurysm ruptures, it will lead to an intracerebral hemorrhage, which can cause hemorrhagic stroke, typically experienced as a sudden focal paralysis or loss of sensation. Charcot-Bouchard aneurysms are aneurysms in the small penetrating blood vessels of the brain. They are associated with hypertension. The common artery involved is the lenticulostriate branch of the middle cerebral artery. Common locations of hypertensive hemorrhages include the putamen, caudate, thalamus, pons, and cerebellum.[citation needed] As with any aneurysm, once formed they have a tendency to ...
Anastomotic aneurysms occurs at various levels of arterial system. Determining their location and incidence rate required investigation of large patient clinical material. Material and methods. In the years 1989-2010 in local centre 230 anastomotic aneurysms were operated in 180 patients. Results. For 187 (81.3%) patients anastomotic aneurysms were localised in the groin, while for remaining 43 (18.7%) they occurred in other localisations. In aortic arch branch they occurred four times (1.7), in descending aorta - three times (1.3%), in abdominal aorta - 14 (6.1%) and in iliac arteries - 6 (2.6%). While for anastomosis with popliteal artery they were diagnosed in 16 (7%) patients. Own clinical material was compared with literature data. Conclusions. Anastomotic aneurysms in over 80% of cases occur in the groin, remaining percentage corresponds to other localisations ...

Venous aneurysms may be either congenital or acquired. Most acquired venous aneurysms develop secondary to a traumatic vascular injury.2-4 Traumatic injury to a particular venous segment may cause disruption and weakness in the vessel wall and gradually result in dilatation and aneurysm formation, either true or false. Peripheral venous aneurysms may be seen in both lower and upper extremities and most have little clinical significance.7 However, they may present with severe clinical pictures such as deep venous thrombosis and pulmonary embolism.8. DSA produced a false positive result in this case. The wrong preoperative diagnosis in this case may be a result of problems attributable to angiography. Like almost every other diagnostic modality, it has user and technique dependent aspects to it. An error in the chain of consecutive steps may have resulted in the misdiagnosis. The premature diagnosis based on colour Doppler ultrasound and early DSA images may have been altered by DSA examination at ...
Development of aspergilloma is common in cases with a fungus ball-like shadow in cavities due to old tuberculosis. Some reports have shown that blood clots tend to appear as a fungus ball-like shadow. A 71-year-old man with a history of pulmonary tuberculosis presented with a fungus ball-like shadow in an old cavity and hemoptysis. There was no evidence of aspergillus infection on various examinations. We confirmed a blood clot and aneurysm of an artery under direct vision by bronchoscopy. A lateral thoracic artery aneurysm was detected by angiography ...
Treatment of a renal artery aneurysm depends on factors such as the size and location of the aneurysm and whether or not symptoms are present. Certain types of small (less than two centimeters, or about three-quarters of an inch) aneurysms may not be treated, but may be observed for growth or development of other complications.. Larger aneurysms (greater than two centimeters, or three-quarters of an inch), dissecting aneurysms, aneurysms causing kidney ischemia (lack of blood flow to the kidney tissue) and hypertension, aneurysms that are growing larger, and aneurysms causing symptoms may be treated surgically.. Because of the increased risk for rupture (bursting), a renal artery aneurysm in a pregnant woman or a woman of childbearing age will generally be treated surgically.. ...
The objectives of this study were to investigate the consistency, patency, and natural history of a vein graft canine aneurysm model and to determine the effectiveness of various coil designs on inducing aneurysm thrombosis. Twenty-one sacculuslike aneurysms were created in mongrel dogs by anastomosing a vein pouch to the common carotid artery. The model produced wide-neck aneurysms with 100% patency. The canine vein graft aneurysm provided an excellent model for the evaluation of endovascular devices. Three types of specially designed platinum coils were placed in the aneurysms: those with simple curves, those with complex curves, and those with flower petal curves and silk fibers. These coils were placed by the endovascular route by means of microcatheters. Flower petal coils with silk fibers were effective in producing thrombosis of the aneurysms, suggesting that coils of the appropriate design may be useful in the endovascular treatment of aneurysms. The other coil designs evaluated, those ...

... outside of the brain.. The most common location for an aneurysm to occur outside of the brain is in the main artery in the stomach-the abdominal aorta. Abdominal Aortic Aneurysms ("AAA") can be lethal if not recognized and treated.. The "normal size" (diameter) of the abdominal aorta is approximately one inch (2.5 cm.) Typically an artery is recognized to have an aneurysm when its diameter increases by 50%, which would be about 1.5" or approximately 4cm from side to side. Arteries behave much like water balloons-that is, the bigger they get, the thinner they get. The thinner they get, the more chance there is of the artery popping or rupturing. A ruptured abdominal aortic aneurysm (AAA) is often fatal as the ruptured artery leads to massive internal bleeding and usually immediate death from exsanguination.. Smaller aneurysms are less likely to rupture than larger ones. Typically, when an aneurysm reaches 5cm, consideration is given to repairing the artery to prevent rupture. The exact ...
TY - JOUR. T1 - Peripheral retinal microaneurysms in chronic leukemia. AU - Jampol, Lee M.. AU - Goldberg, Morton F.. AU - Busse, Bruce. PY - 1975/8. Y1 - 1975/8. N2 - Of 25 patients with chronic leukemia, there was clinical evidence of peripheral retinal microaneurysm formation in two of eight patients with chronic lymphocytic leukemia and six of 17 patients with chronic myelogenous leukemia. There was no proliferative retinopathy in any of the 25 patients. An elevated leukocyte count seemed necessary for microaneurysm formation in leukemia, although some patients with elevated counts had no microaneurysms. The prolonged leukocytosis of chronic leukemia can produce peripheral capillary dropout, vascular stagnation, microaneurysm formation, and, rarely, peripheral proliferative retinopathy similar to sickle cell disease..

Circulatory Failure and Lactic Acidosis Associated with Giant Saphenous Vein Graft Aneurysm, Rick Mooi, Carsten Arnoldussen and Jos le Noble
Results: In our experience, there were 47 males and the mean age was 62 years (16-80). In patients with PAAs and VAAs, technical success with the MFM was 100%. At 30 days, there were no deaths. Initial MFM patency was 97.5% (39/40) with patency of the thrombosed MFM successfully restored. Longer-term follow-up (mean 16±8 months) demonstrated progressive thrombosis and shrinkage of the aneurysm sacs and all side-branches were patent. In patients with aortic aneurysms, technical success was 100%, with no complications and no deaths at 30 days. Longer-term follow-up (8±7 months) demonstrated aneurysm-related survival of 100%, all-cause survival of 83.3%, intervention-free survival of 100% and 100% patency of the side branches. The longest duration for aneurysm sac thrombosis was 18 months. A significant mean diameter reduction was observed at 6 months (17.3 mm for the transversal maximal diameter and 13.83 mm for the antero-posterior diameter) in the TAAA group. In the literature review, there ...

OBJECTIVES: Medical therapies have not proven to be effective in halting or reversing the progressive dilation of aneurysms. Further, no therapy exists for small aortic aneurysms due to the significant risks of surgical repair. Smooth muscle cells (SMCs) have the ability to produce extracellular matrix (ECM) that is destroyed in the vessel wall during aneurysm formation. We hypothesized that polymeric nanoparticles bearing ascorbic acid (AA) and retinoic acid (RA) will be effective in reducing inflammation and promoting SMC synthesis of the ECM proteins, collagen and elastin, thus inhibiting aneurysm formation in vivo.. METHODS and RESULTS: Block co-polymer nanoparticles made of polyethylene oxide (PEO) and poly(ϵ-caprolactone) (PCL) capable of bearing both hydrophilic (AA) and hydrophobic (RA) drugs were fabricated by the formation of an organic/aqueous bi-phase stable emulsion. The particles were analyzed to ensure proper spherical morphology, nano diameter, and entrapment of drug prior to in ...
Aortic Aneurysm An aneurysm is a bulge or ballooning in the wall of an artery. Arteries are blood vessels that carry oxygen-rich blood from the heart to other parts of the body. If an aneurysm grows large, it can burst and cause dangerous bleeding or even death. Most aneurysms are in the infrarenal aorta (aorta below the kidney). The aorta is the largest artery in the body

Diabetes is a negative risk factor for aortic aneurysm, but the underlying explanation for this phenomenon is unknown. We have previously demonstrated that Cell Division Autoantigen 1 (CDA1), which enhances TGF-β signaling, is upregulated in diabetes. We hypothesized that CDA1 plays a key role in conferring the protective effect of diabetes against aortic aneurysms. Male wildtype, CDA1 knockout, Apolipoprotein E (ApoE) knockout and CDA1/ApoE double knockout (dKO) mice were rendered diabetic. Whereas aneurysms were not observed in diabetic ApoE knockout and wildtype mice, 40% of diabetic dKO mice developed aortic aneurysms. These aneurysms were associated with attenuated aortic TGF-β signaling, reduced expression of various collagens as well as increased aortic macrophage infiltration and matrix metalloproteinase12 expression. In the well characterized model of angiotensin II (AngII) induced aneurysm formation, concomitant diabetes reduced fatal aortic rupture and attenuated suprarenal aortic ...

Splenic artery aneurysm (SAA) is defined as an abnormal dilatation of the splenic artery more than 1 cm in diameter. It was first described on cadavers in 1770 by Beaussier [7]. It accounts for approximately 60 % of all visceral arterial aneurysms [2]. It is the third most common intra-abdominal aneurysm, following aortic and iliac artery aneurysms [3]. SAA is rarely seen with a prevalence of 1 % [1]. It is four times more common in females compared to males [8-10]. Risk factors correlating to the development of SAA include fibromuscular dysplasia, collagen vascular diseases, female gender, history of multiple pregnancies, and portal hypertension, although the pathogenesis is not fully understood [11].. Splenic artery pseudoaneurysms are less prevalent than true SAA. They differ from true SAA in that the dilatation occurs following the disruption of one or more layers of the vessel wall. Splenic artery accounts for the majority of splanchnic pseudoaneurysms. Unlike true SAA, they have a slight ...

Intracranial aneurysm, also known as brain aneurysm, is a cerebrovascular disorder in which weakness in the wall of a cerebral artery or vein causes a localized dilation or ballooning of the blood vessel. Aneurysms in the posterior circulation (basilar artery, vertebral arteries and posterior communicating artery) have a higher risk of rupture. Basilar artery aneurysms represent only 3%-5% of all intracranial aneurysms but are the most common aneurysms in the posterior circulation. Cerebral aneurysms are classified both by size and shape. Small aneurysms have a diameter of less than 15 mm. Larger aneurysms include those classified as large (15 to 25 mm), giant (25 to 50 mm), and super-giant (over 50 mm). Saccular aneurysms, also known as berry aneurysms, appear as a round outpouching and are the most common form of cerebral aneurysm. Fusiform dolichoectatic aneurysms represent a widening of a segment of an artery around the entire blood vessel, rather than just arising from a side of an arterys ...
A case of ruptured gastroepiploic artery aneurysm associated with thoracic aortic aneurysm is presented. Gastroepiploic artery aneurysms are rare, but the association of visceral artery aneurysm and aortic aneurysm is clinically significant and is emphasized in this report.
Congenital true aneurisms of peripheral arteries especially on the hand are rare and idiopathic. The present case is focused on the multiple aneurysms of a young boy on both radial and ulnar arteries since birth. The clinical indications include painful ulcers on the right middle finger, discoloration and swelling of dorsum of ulnar side of right hand. In addition, patchy necrosis of fifth finger with increased intensity of pain was observed. Here we successfully treated both aneurysms with partial amputation of the digit and the growth of the skin on both sides of the palm was restored by groin flap.
An aneurysm is defined as dilatation of the artery greater than 50% in diameter. Aneurysms are categorized as fusiform or saccular. The saccular aneurysms of the ascending aorta are rarely seen and are usually life-threatening. Excessive use of biologicglue, graft infection, mediastinitis, aortic dissection, atherosclerosis, hypertension, degeneration of a penetrating atherosclerotic ulcer, poorsurgical technique, trauma, fungal infections and previous aortic surgery (presumably due to the cannulation site) are the etiologic risk factors for the development of a false or true aneurysm of the ascending aorta [1]. There are a few reports for saccular aneurysm of the ascending aorta which are following coronary artery bypass grafting surgery. The wall stressis greater in saccular aneurysms rather than fusiform aneurysms. The disruption of the vesse lwall at the cannulation site oral long the aortic suture lines lead to saccular aneurysm.. Theaortic false aneurysm may surrounded and restricted by ...
