Most common are the saccular (berry) aneurysms located at branch points in CIRCLE OF WILLIS at the base of the brain. Vessel rupture results in SUBARACHNOID HEMORRHAGE or INTRACRANIAL HEMORRHAGES. Giant aneurysms (>2.5 cm in diameter) may compress adjacent structures, including the OCULOMOTOR NERVE. (From Adams et al., Principles of Neurology, 6th ed, p841)Aneurysm: Pathological outpouching or sac-like dilatation in the wall of any blood vessel (ARTERIES or VEINS) or the heart (HEART ANEURYSM).

Blood-filled aneurysms are dangerous because they may burst. Fibrous aneurysms interfere with the heart function through the loss of contractility. True aneurysm is bound by the vessel wall or cardiac wall. False aneurysms are HEMATOMA caused by myocardial rupture.Aortic Aneurysm, Thoracic: An abnormal balloon- or sac-like dilatation in the wall of the THORACIC AORTA.

Endovascular treatment of ruptured, peripheral cerebral aneurysms: parent artery occlusion with short Guglielmi detachable coils. (1/314)

We report two cases of distal cerebral aneurysms that were treated by parent artery occlusion with short Guglielmi detachable coils (GDCs). One patient had a presumed mycotic aneurysm of the distal left posterior cerebral artery, and the other had a partially clipped aneurysm of the distal right anterior inferior cerebellar artery that had hemorrhaged. Short GDCs allow controlled, accurate occlusion of the parent artery at the aneurysmal neck.  (+info)

Video-assisted crossover iliofemoral obturator bypass grafting: a minimally invasive approach to extra-anatomic lower limb revascularization. (2/314)

Graft infection continues to be one of the most feared complications in vascular surgery. It can lead to disruption of anastomoses with life-threatening bleeding, thrombosis of the bypass graft, and systemic septic manifestations. One method to ensure adequate limb perfusion after removal of an infected aortofemoral graft is extra-anatomical bypass grafting. We used a minimally invasive, video-assisted approach to implant a crossover iliofemoral obturator bypass graft in a patient with infection of the left limb of an aortofemoral bifurcated graft. This appears to be the first case report describing the use of this technique.  (+info)

Cryptococcal aortitis presenting as a ruptured mycotic abdominal aortic aneurysm. (3/314)

Mycotic processes occasionally complicate atherosclerotic aortic disease and usually require aggressive surgical therapy to control sepsis and prevent arterial rupture. Rarely, fungal organisms are responsible for primary infection of the abdominal aorta. We report the first case of Cryptococcal aortitis presenting as a ruptured abdominal aortic aneurysm. The surgical, pathologic, and microbiologic aspects of fungal aortitis are discussed.  (+info)

Surgery after failed percutaneous renal artery angioplasty. (4/314)

PURPOSE: This retrospective review describes the surgical management of 51 patients after failed percutaneous renal artery angioplasty (F-PTRA). METHODS: From January 1987 through June 1998, 51 consecutive patients underwent surgical repair of either atherosclerotic (32 patients) or fibromuscular dysplastic (FMD; 19 patients) renovascular vascular disease after F-PTRA. These patients form the basis of this report. Surgical repair was performed for hypertension (29 patients with atherosclerosis: mean blood pressure, 205 +/- 34/110 +/- 23 mm Hg; 18 patients with FMD: mean blood pressure, 194 +/- 24/118 +/- 18 mm Hg) or ischemic nephropathy (20 patients with atherosclerosis: mean serum creatinine level, 2.0 +/- 0.8 mg/dL; three patients with FMD: mean serum creatinine level, 2.0 +/- 1.1 mg/dL). Emergency operation was required in four patients for acute renal artery thrombosis (one patient with atherosclerosis, one patient with FMD), renal artery rupture (one patient with atherosclerosis), or infected pseudoaneurysm (one patient with atherosclerosis). Operative management, blood pressure and renal function response to operation, and dialysis-free survival rate were examined and compared with 487 patients (441 patients with atherosclerosis, 46 patients with FMD) treated by operation alone. RESULTS: Among the patients with atherosclerotic renovascular disease, there were three postoperative deaths (9.4%) after repair for F-PTRA. Secondary operative repair was associated with emergent repair or nephrectomy in 16% of cases, while more extensive renal artery exposure and more complex operative management was required in 50% of patients with atherosclerosis and 65% of patients with FMD repaired electively. Among the 28 operative survivors with hypertension and atherosclerotic renovascular disease, blood pressure benefit after F-PTRA was significantly lower when compared with patients with atherosclerosis who underwent treatment with operation only (57% vs 89%; P <.001). However, blood pressure benefit in the 19 patients with FMD did not differ (89% vs 96%). Among the 28 patients with atherosclerosis, preoperative estimated glomerular filtration rate (EGFR) as compared with postoperative EGFR was significantly increased (47.4 +/- 4.2 mL/min/1.73m(2) vs 56. 6 +/- 5.1 mL/min/1.73m(2); P =.002). However, EGFR prior to PTRA was not significantly different from postoperative EGFR (51.6 +/- 3.4 mL/min/1.73m(2) vs 56.6 +/- 4.9 mL/min/1.73m(2); P =.121). As compared with patients with atherosclerosis who underwent treatment with operation alone, there was no difference in the dialysis-free survival rate. CONCLUSION: Operative repair after F-PTRA was altered in 59% of the patients with atherosclerosis and in 68% of patients with FMD. Blood pressure benefit for patients with FMD was unchanged after F-PTRA. However, the blood pressure benefit was significantly decreased among patients with atherosclerosis. Decreased EGFR after F-PTRA was recovered with operative renal artery repair. However, postoperative EGFR as compared with EGFR prior to PTRA was unchanged. Blood pressure and renal function response after F-PTRA for atherosclerotic renovascular disease warrants further study.  (+info)

Disseminated coccidioidomycosis complicated by vasculitis: a cause of fatal subarachnoid hemorrhage in two cases. (5/314)

We describe two cases of disseminated coccidioidomycosis that were complicated by fatal subarachnoid hemorrhage. In the first case, a left middle cerebral artery aneurysm and long-segment vasculitis occurred. In the second case, MR imaging revealed an enlarging coccidioidal granuloma at the tip of the basilar artery, and the artery subsequently ruptured. Fatal intracranial hemorrhage is a rare complication of disseminated coccidioidomycosis.  (+info)

Lumbar vertebral osteomyelitis with mycotic abdominal aortic aneurysm caused by highly penicillin-resistant Streptococcus pneumoniae. (6/314)

We present a case of vertebral osteomyelitis with an adjacent abdominal aortic mycotic aneurysm caused by a highly penicillin-resistant Streptococcus pneumoniae strain. The occurrence of all three phenomena in a single patient has not been previously described. This presentation offers the opportunity to reflect on the increasing incidence of S. pneumoniae as a resistant pathogen, the treatment of highly penicillin-resistant S. pneumoniae, and the etiologic agents of both vertebral osteomyelitis and mycotic aneurysm.  (+info)

Arterial reconstruction with deep leg veins for the treatment of mycotic aneurysms. (7/314)

PURPOSE: Mycotic pseudoaneurysms (MPA) remain challenging clinical problems. Primary surgical management includes control of hemorrhage and debridement of the infected arterial wall. Because critical ischemia may develop after arterial resection, revascularization has been a secondary goal of treatment. Standard anatomic graft placement or prosthetic bypass grafting has been compromised by a high rate of recurrent infection. Extra-anatomic reconstruction is preferred, with the basic goals being threefold: (1) the use of autogenous graft material to reduce the risk of reinfection; (2) the avoidance of significant size mismatches; and (3) graft placement that is anatomically inaccessible, because drug abuse causes many of these lesions. This study reviews a recent series of MPAs applying these treatment goals. METHODS: In a 2-year period, the superficial femoral and proximal popliteal veins were used in the repair of eight MPAs of the common femoral (5), common iliac (1), and brachial (1) arteries, and the infrarenal aorta (1). Most patients (5 of 7) were known intravenous drug users, who had a painful pulsatile mass in an injection area. Two patients had systemic sepsis, one patient with an infected common iliac pseudoaneurysm and one patient with an MPA of the infrarenal aorta. The diagnosis of MPA was made by means of duplex/computed tomography scanning and confirmed by means of arteriography in all cases. RESULTS: Obturator bypass grafting was performed by using a reversed deep leg vein in the five femoral MPAs. An ilioiliac, cross-pelvic bypass grafting procedure with a deep vein was used to repair an MPA of the common iliac artery. A deep vein was also used as a "pantaloon" aortobiiliac graft and for a brachial artery repair. Staphylococcus aureus was revealed by means of cultures in nearly all cases. Distal arterial perfusion was normal after reconstruction. Patients had no significant postoperative leg swelling. No new venous thrombosis below the level of deep vein harvest was revealed by means of duplex scanning. There were no septic complications. CONCLUSION: The superficial femoral/popliteal veins may be particularly useful for limb revascularization in patients with MPAs. This autogenous conduit provides an excellent size-match and a suitable length for reconstruction, because peripheral, axial arteries are generally affected. No clinically significant limb morbidity was related to deep vein removal. Late follow-up is challenging in such cases, but will be required to accurately determine the durability of this strategy.  (+info)

Aortitis due to Salmonella: report of 10 cases and comprehensive review of the literature. (8/314)

We describe ten cases of aortitis due to Salmonella that were treated at the University of Toronto-affiliated Hospitals between 1978 and 1997. Predisposing conditions included hypertension, diabetes mellitus, and myelodysplastic syndrome. Main presenting symptoms were fever and abdominal and back pain. The most frequent site involved was the abdominal aorta, followed by the thoracic aorta. All but one patient were treated with intravenous bactericidal antibiotics; seven also underwent surgery, four with axillobifemoral grafts and three with in situ grafts. Four of seven patients died within 1 month of the surgical procedure (three patients with in situ grafts and one patient with axillobifemoral graft). We also reviewed the pathogenesis, clinical and laboratory characteristics, and treatment of 140 cases of aortitis due to Salmonella reported in the literature since 1948. The use of bactericidal antibiotics, together with early surgical intervention and long-term suppressive antibiotic therapy, has led to improved survival.  (+info)

Listeria monocytogenes is a rare pathogen that principally affects neonates, pregnant women and immunosuppressed patients. It most commonly causes gastroenteritis in healthy adults and central nervous system infection in immunosuppressed patients. Cardiovascular infection due to Listeria monocytogenes is rare and tends to cause endocarditis.1 This article presents the case of a mycotic aortic aneurysm due to Listeria monocytogenes.. A 76-year-old man with a history of hypertension, type 2 diabetes mellitus, dyslipidaemia and ischaemic heart disease attended the emergency department following 2 months of general discomfort, hyporexia, low back pain and 7kg weight loss in the previous 2 weeks. The patient was afebrile and the physical examination revealed no significant findings. The vascular examination found distal pulses in both lower limbs. Bloods were normal, except for blood glucose at 460mg/dl. The chest and abdominal X-rays were normal. After normalising the patients blood glucose levels, ...

Herein, we describe a unique case of safe catheter-directed lysis of an acutely thrombosed iliac artery following covered stent placement for treatment of an actively bleeding infected pseudoaneurysm. Our management approach is discussed.. AB - Conventional absolute contraindications to catheter-directed thrombolysis include active or ...
The term mycotic aneurysm is a misnomer that has nevertheless been generally adopted to describe aneurysms that occur secondary to the infectious destruction of the arterial wall. Mycotic aneurysm secondary to tuberculous infection of the aorta is a rare and life-threatening disease. Both abdominal and thoracic aorta are involved with equal frequency.1 Tuberculous aneurysms are usually a consequence of transmural perforation caused by direct extension to the vessel from a contiguous focus, often lymphadenitis, but also pulmonary,2 digestive or vertebral. Other mechanisms implicated are haematogenous contamination through the vasa vasorum,3 or an autoimmune response to tuberculosis. Clinical features are highly variable, ranging from asymptomatic aneurysm with or without constitutional symptoms, pulsatile or palpable mass, chest pain, dysphagia, hoarseness, abdominal pain, back pain, to frank rupture, bleeding and shock. The key to the diagnosis is a high index of suspicion. A 55-year-old man ...

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 ...

Case Reports: Three patients (2 women and 1 man aged 52, 68, and 43 years, respectively) developed pseudoaneurysm of the ascending aorta following thoracic organ transplantation. Due to the prohibitive risk of open surgery in each case, an endovascular repair of the ascending aorta was performed, with implantation of 1 to 3 stent-grafts to span the lesions. Follow-up imaging demonstrated complete exclusion of the pseudoaneurysms, with excellent outcomes at 4 months, 6 months, and 3 years. Conclusion: Stent-grafting of the ascending aorta represents a viable approach to pseudoaneurysm in the post-transplant setting.. AB - Purpose: To demonstrate ...

The red arrow in both illustrations shows an aneurysm (weak spot in vascular wall) of the right front cerebral artery (A. carotis interna right, front view). For the safe treatment of this aneurysm, a tubular metal mesh (stent) was first inserted in the vascular wall and precisely placed above the mouth of the aneurysm. The almost invisible stent is marked with green dotted lines on the right part of the illustration. On both of its ends, it is marked with visible dark markers which the green arrows are pointing out. The purpose of a stent in the treatment of aneurysms is to narrow the mouth of the aneurysm with a mesh. Then, the platinum coils can be inserted safely in the aneurysm through the mesh. The platinum coils seal the aneuryms and can, in difficult cases, be better held in the aneurysm due to the underlying stent. The platinum coils are inserted in the aneurysm via a very fine, tiny plastic tube (so-called micro-catheter) through the mesh. In this case, the path of the micro-catheter ...
This is a transforming event in cerebrovascular surgery," said Nelson, who has implanted the device in about 75 patients in the U.S.. Large aneurysms, which measure between 10 mm and 25 mm, and giant aneurysms, which are greater than 25 mm in size, are rare, with about 2,000 reported cases each year. There is a greater risk of rupture with giant aneurysms, and they are much more difficult to treat.. Smaller, uniformly shaped aneurysms with small necks attaching them to the artery can be treated by surgically clipping the base of the aneurysm, or by pushing platinum coils into the aneurysms to initiate a clotting reaction. But clipping the base of an large aneurysm is very difficult and extremely risky, and often coils wont fit into an oddly-shaped aneurysm, explained Nelson.. The flexible Pipeline, which resembles a mesh tube, is inserted into the artery from which the aneurysm has developed. It works by cutting off the blood supply to the aneurysm, which, over time, eliminates the aneurysm ...
Results Inclusions started in July 2014. End of February 2016, 92 patients with 92 aneurysms were included. The expectation is to have inclusions completed end of April 2016. Most patients were females (80/92, 87.0%). All but one patient were mRS 0 or 1 before the treatment.. Among the 92 aneurysms, 22 (23.9%) were aneurysm remnant after a previous treatment and the 70 others (76.1%) were unruptured. Aneurysm locations were internal carotid artery (n = 83, 90.2%), anterior communicating artery (n = 6, 6.5%), and middle cerebral artery (n = 3, 3.3%). Aneurysm size was ,10 mm in 57 aneurysms (62.0%), 10 to 24 mm in 31 aneurysms (33.7%), and ,24 mm in 3 aneurysms (3.3%).. Neck size was ,4 mm in 24/91 aneurysms (26.4%) and , or = 4 mm in 67/91 aneurysms (73.6%).. Placement of the flow diverter was achieved in all cases. Intra-operative events were reported in 7/92 patients (7.6%), including technical problems (n = 3), thromboembolic events (n = 3), and others (n = 1). Postoperative events, ...

Cerebral aneurysms are bulging, weakened areas in the wall of a brain artery that create abnormal widening, ballooning or a fluid-filled internal blister. Also called brain aneurysms or intracranial aneurysms, they can result from an injury, or they can occur spontaneously. Arteries in any part of the brain can develop an aneurysm, but they are usually located in the front of the brain, which supports the rest of the brain tissue with oxygen-rich blood. The majority of brain aneurysms are small - less than four-tenths of an inch in diameter - and occur without any symptoms. These smaller aneurysms may not rupture (tear), but as the size of an aneurysm increases, so does the risk of rupture or developing another aneurysm.. The wall of an aneurysm is thin and weak, meaning it could rupture. When a blood vessel ruptures and bleeds into the brain, a stroke occurs and there is a significant risk to a persons life. The cells and tissue in the brain do not get the oxygen and nutrients needed, pressure ...
The clinical characteristics of elderly patients with multiple IAs were studied in 481 patients by Inagawa [31]. Patients were divided into two groups: group 1 - 59 years of age or younger and group 2- 60 years of age or older. Of the 481 patients, 136 (28%) had multiple aneurysms. The percentage of patients with multiple aneurysms was 30% for group 1 and 27% for group 2. The rate of multiple aneurysms was significantly less in males than in females (17% versus 31%). Due to the small sample size, no significant difference could be found between the male and female age groups in terms of the number of aneurysms by gender, yet it is important to highlight that there were no male patients reported in that series with 5 aneurysms or more. The only patients in this series reported to have 5 aneurysms or more were females; one patient in group 1 with 5 aneurysms and one with 6 aneurysms, and a single female patient with more than 5 aneurysms in group 2. Comparable findings were reported by Wilson et ...
Ultrasonography showed a 14×8-mm area of decreased echogenicity with arterial flow on Doppler examination. Anatomic details were further delineated by arteriography, which showed a false aneurysm arising from the superficial palmar arch. Clinical presentation, ultrasonography, and angiography suggested a mycotic aneurysm. In the presence of aortic regurgitation, endocarditis was suspected and was actively searched for. Transthoracic echocardiography confirmed the known aortic regurgitation but revealed no vegetations. The patient refused transesophageal cardiac ultrasound. Blood cultures revealed the presence of a penicillin-multisensitive α-hemolytic streptococcus (streptococcus parasanguinis). A 4-week treatment of intravenous penicillin was initiated, with progressive improvement of local symptoms. The mycotic aneurysm was surgically removed. Histological analysis of the aneurysm revealed the presence of many Gram-positive bacteria, thereby confirming the diagnosis. Under antibiotic ...
These data demonstrate not only that the assigned cohorts were the same as in our publication but also that the actually treated aneurysms had similar outcomes. Despite the inclusion of more-difficult aneurysms that were assigned to endovascular coiling but were actually treated with clipping, plus those actually treated with clipping because of large hematomas, the results demonstrate a slight, although statistically nonsignificant, benefit to clipping. Thus, from a pool of 314 randomized patients, all those randomized to undergo clipping (with the exception of a single patient) had their aneurysms actually clipped, and in addition, 36% of cross-over patients who were randomized to undergo coiling had their aneurysms actually clipped. This finding emphasizes that the use of clipping to treat all anterior circulation aneurysms could achieve results equal to those for the selected anterior circulation coiling treatment cohort.. The lack of middle cerebral artery (MCA) aneurysms in the cohorts ...

There is no disease more conducive to clinical humility than aneurysm of the aorta."-Osler.. Aneurysms of various types have long been recognized. The first type to be described came to be known as false aneurysm, because following rupture or wounding of an artery, the sac which formed had for its walls the adjacent tissues or newly formed connective tissue. Arterio-venous aneurysm is the term applied to a communication between an artery and vein. If it is direct, the lesion is known as aneurysmal varix, whereas if there is an interposed sac it is named varicose aneurysm. Aneurysms may rarely be ...
Experimental saccular aneurysm models are necessary for testing novel surgical and endovascular treatment options and devices before they are introduced into clinical practice. Furthermore, experimental models are needed to elucidate the complex aneurysm biology leading to rupture of saccular aneurysms. Several different kinds of experimental models for saccular aneurysms have been established in different species. Many of them, however, require special skills, expensive equipment, or special environments, which limits their widespread use. A simple, robust, and inexpensive experimental model is needed as a standardized tool that can be used in a standardized manner in various institutions. The microsurgical rat abdominal aortic sidewall aneurysm model combines the possibility to study both novel endovascular treatment strategies and the molecular basis of aneurysm biology in a standardized and inexpensive manner. Standardized grafts by means of shape, size, and geometry are harvested from a ...
STIAS Fellow Malebogo Ngoepe during her seminar presentation on 2 November 2017. Ngoepe was presenting her project entitled Comparative computational study of thrombosis in cerebral and abdominal aortic aneurysms to STIAS fellows. She is from the Department of Mechanical Engineering at the University of Cape Town and is currently an Iso Lomso fellow.. Thrombosis - clotting which causes blockage of blood vessels - is the underlying condition for many cardiovascular diseases. Clotting is also closely linked to aneurysms, which are balloon-like expansions of blood vessel walls caused by weakening of the wall layers. Aneurysms are most commonly found on blood vessels of the brain and on the aorta, and are at risk of rupture with subsequent morbidity or mortality. Clots are observed in both ruptured and unruptured aneurysms. Clots that grow in aneurysms can either assist by sealing off the aneurysm, can exacerbate the situation by speeding up the time to rupture, or can break away and cause problems ...
Since often these aneurysms are asymptomatic until they rupture, causing severe neurologic problems as well as possibly being fatal. Due to their weakened walls, brain aneurysms can acutely rupture, causing massive hemorrhage that may lead to death.The presence of associated high blood pressure from PKD increases the likelihood of aneurysm rupture, as does a prior family history of aneurysm rupture ...
Pseudoaneurysms of the lumbar arteries are infrequent, and are most often found incidentally after trauma to the lumbar spine. More rarely, they are an iatrogenic complication from diagnostic or therapeutic procedures, particularly of the kidney. The
Pseudoaneurysm formation after vascular reconstruction is a rarely encountered problem in the treatment of peripheral arterial disease. It has most commonly been described in the vascular surgical literature as a delayed complication of lower extremity bypass surgery, and the usual mode of repair has been surgical. Recent advances in minimally invasive therapy for this clinical entity have centered on ultrasound-guided compression and thrombin injection to obliterate the cavity and restore vascular integrity. With the advent of stent-supported angioplasty, endovascular methods of treatment for
This study will investigate cerebral (brain) aneurysms and their possible inheritance patterns in families. It will try to determine how often brain aneurysms occur in families in which more than one member has had an aneurysm and to find the gene or genes that contribute to their development.. People in families in which more than one family member had a cerebral aneurysm are eligible for this 1-day study. They will undergo the following procedures:. ...
An aneurysm is a weak area in the wall of a blood vessel that causes the blood vessel to bulge or balloon out. There are many different types of aneurysms. A berry aneurysm can vary in size from a few millimeters to over a centimeter. Giant berry aneurysms can reach well over 2 centimeters.

Aneurysms, described most often as a ballooning or bulging of an artery wall, occurs at a point of weakness in the blood vessel wall. Aneurysms can occur anywhere, but two common sites are in the brain and the aorta. The exact cause is not known, but experts believe family history, a history of traumatic injury, smoking and hypertension (high blood pressure) may contribute to the risk. Aneurysms are more common in men than women, and family history and genetics can also play an important role.. ...

It is normal to feel a throb at the site where you take a pulse to check your heart rate. As the heart forces blood through your body, you can feel a throbbing in the arteries wherever they come close to the skin surface, such as the wrist, neck, or upper arm.. An aneurysm is a bulging section in the wall of a blood vessel and causes a throbbing pulse where the blood vessels has become stretched out and thin. This area of the blood vessel bulges out, is weak, and may cause bleeding when it bursts or ruptures. Aneurysms most often affect the large artery in the chest and abdomen (aorta) and arteries that supply the brain, heart, and legs.. Although it is not unusual to have an aneurysm without other symptoms, common symptoms include:. ...
The exact cause of an aneurysm isnt clear, but certain factors can contribute to developing one, such as high blood pressure. We explain the different types of aneurysms, the symptoms you should watch out for, and how one is diagnosed. Well also explain how to prevent and treat aneurysms.

An aneurysm is a weak point in a blood vessel wall, most commonly in an artery. Blood pressure tends to push the weakened section of an arterial wall outward, forming a balloon-like projection. This condition by itself isnt especially harmful, but the artery is prone to rupture. A ruptured aneurysm breaks the artery and allows uncontrolled bleeding to occur, which can be fatal.
An aneurysm is an abnormal bulge in the wall of an artery, an inflated balloon of blood. An aneurysm is extremely dangerous since it may result in rupture and subsequent hemorrhage or in the development of a serious clot.

DEAR Dr. Fritz, Hi, doc. Please call me Macbeth. I am writing you because I am really quite anxious lately. My sister had just been diagnosed with aneurysm. The truth is, this sounds so foreign to me. But, I have heard this is quite deadly, especially if this would rupture. So, doc, what is an aneurysm? How do I know if I have one? What should we look up to for signs that this has already ruptured? Are there factors or diseases which would make one a most probable target? Are there treatments?
An aneurysm is a bulging, weak area in the wall of a blood vessel. An aneurysm may occur in any blood vessel, but most often develops in an artery rather than a vein.
