1/76. Primary venous aneurysms--case reports.Venous aneurysms are rare lesions that may be the source of pulmonary emboli and can result in death. The authors have recently treated several patients who had venous aneurysms of the upper extremity, lower extremity, and jugular system. Venous aneurysms usually appear to have a safe natural history in these locations, although all of the reported patients required surgery after the development of symptoms owing to complaints of pain, and/or cosmetic appearance, and/or a diagnosis of thrombosis. These cases are presented, along with a review of venous aneurysms occurring at other sites and their causes.- - - - - - - - - - ranking = 1keywords = aneurysm (Clic here for more details about this article) |
2/76. Ruptured mycotic pulmonary artery aneurysm: an unusual complication of right-sided endocarditis.Mycotic pulmonary aneurysm is an infrequently diagnosed complication of endocarditis. We report here a case of mycotic pulmonary aneurysm and a review of 25 cases from the literature. The mortality rate is greater than 50%. Prompt diagnosis is necessary because early intrasaccular embolization and/or surgical repair is essential to avoid death from rupture of the aneurysm.- - - - - - - - - - ranking = 0.875keywords = aneurysm (Clic here for more details about this article) |
3/76. Paradoxical pulmonary embolism secondary to aortocaval fistula: diagnosis by helical CT.Spontaneous aortocaval fistula is an unusual but well recognized complication of abdominal aortic aneurysm. Reports of aortocaval fistula as the source of pulmonary embolism are rare. We report a case of paradoxical pulmonary embolism secondary to an aortocaval fistula. The abdominal aortic aneurysm and the associated aortocaval fistula were well demonstrated on helical CT, leading to early diagnosis and prompt surgical treatment with good clinical outcome.- - - - - - - - - - ranking = 0.25keywords = aneurysm (Clic here for more details about this article) |
4/76. Giant unruptured aneurysm of the thoracic aorta--a case report.An asymptomatic 88-year-old woman underwent a screening medical examination. The chest x-ray film showed a large mediastinal mass with calcification. Both chest computed tomography and nuclear magnetic resonance imaging revealed an unruptured aortic aneurysm, predominantly affecting the ascending aorta and the proximal part of the aortic arch. Its maximum diameter was 10.5 cm. An ascending aortic aneurysm more than 10 cm in diameter is very rare. She died of acute pulmonary embolism unrelated to the aneurysm, and autopsy indicated that the etiology of the aneurysm was atherosclerotic degeneration. Retrospectively, the natural progression of the aneurysm was able to be followed on a series of chest x-ray films obtained over 18 years.- - - - - - - - - - ranking = 1.125keywords = aneurysm (Clic here for more details about this article) |
5/76. Iliac arteriovenous fistula secondary to iliac aneurysm rupture associated with pulmonary embolism and anuria.We present a case of iliac aneurysm rupture that started with high-output cardiac failure and anuria and later presented as a pulmonary embolism that needed a preoperatory filter for the cava vein.- - - - - - - - - - ranking = 0.625keywords = aneurysm (Clic here for more details about this article) |
6/76. Bilateral pulmonary artery aneurysm associated with bilateral pulmonary thromboembolism, superior vena caval thrombosis, and Chagas' disease--a case report.The authors report a case of bilateral pulmonary artery aneurysm in a patient with chronic Chagas' disease and compensated congestive heart failure in whom clinical clues suggested pulmonary thromboembolism, and the actual nature of the lesions was discovered at the time of conventional imaging investigations. This case shows the rarity of bilateral pulmonary aneurysm associated with bilateral pulmonary thromboembolism and the importance of an awareness of this condition in the differential diagnosis for lung masses.- - - - - - - - - - ranking = 0.75keywords = aneurysm (Clic here for more details about this article) |
7/76. Traumatic venous aneurysm of the popliteal vein with outcome: a case report and review of the literature.A case of sudden death due to recurrent pulmonary thromboembolism is described. The fatality took place three and a half weeks following blunt trauma to the left popliteal region. The patient died unexpectedly. autopsy revealed the source of the emboli as a sacciform venous aneurysm of the popliteal vein, an entity seldom described, but important to consider in cases of soft tissue popliteal masses or unexplained pulmonary embolism, especially in otherwise healthy individuals.- - - - - - - - - - ranking = 0.625keywords = aneurysm (Clic here for more details about this article) |
8/76. Aneurysm of the inferior vena cava in a 5-year-old boy.The authors present a case of an aneurysm of the inferior vena cava in a 5-year-old boy. The boy suffered from acute pulmonary and paradoxical cerebral embolism after a minor abdominal trauma. magnetic resonance angiography was the key for correct diagnosis of the retroperitoneal process and helped develop a strategy for surgery. The boy underwent resection of the aneurysm and a prosthetic replacement of the distal inferior vena cava. Aneurysms of the inferior vena cava are very rare conditions. The diagnosis is difficult because they may mimic a retroperitoneal tumor. thrombosis and embolism are common complications of aneurysms of the vena cava.- - - - - - - - - - ranking = 0.375keywords = aneurysm (Clic here for more details about this article) |
9/76. Should thrombolysis be contraindicated in patients with cerebral arteriovenous malformations?OBJECTIVES: To report the successful and uncomplicated use of systemic thrombolysis for massive pulmonary embolism in a patient with a known cerebral arteriovenous malformation and to suggest that the presence of an unruptured arteriovenous malformation or aneurysm should not be considered an absolute contraindication to systemic thrombolysis. DESIGN: Case report. SETTING: A 16-bed adult neurologic/medical intensive care unit in a university hospital. patients: A patient developed a massive pulmonary embolism the morning after elective cerebral embolization of a large unruptured cerebral arteriovenous malformation. INTERVENTION: radial artery catheterization, arterial blood gas measurements, mechanical ventilation, vasopressors, pulmonary perfusion scan, echocardiogram, head computed tomography, heparin therapy, and systemic recombinant tissue plasminogen activator therapy. MEASUREMENT AND MAIN RESULTS: The patient required emergent mechanical ventilation and vasopressor support for respiratory and hemodynamic failure. Echocardiogram showed acute right heart failure, and pulmonary perfusion scan demonstrated massive pulmonary embolism. Despite intravenous heparin therapy, the patient had worsening hypotension and acidosis and we therefore treated with recombinant tissue plasminogen activator. Within the next day the patient was weaned from vasopressor support and extubated. neurologic examination remained normal, and follow-up head computed tomography revealed no evidence of intracranial hemorrhage. CONCLUSION: Known arteriovenous malformations or aneurysms are considered a contraindication to thrombolysis, although the true risk of thrombolysis-precipitated intracranial hemorrhage is unknown. We believe that this risk is low in the setting of a previously unruptured arteriovenous malformation or aneurysm. The decision to use systemic thrombolysis in a patient with a known vascular malformation should be individualized.- - - - - - - - - - ranking = 0.375keywords = aneurysm (Clic here for more details about this article) |
10/76. Systemic thrombolytic therapy after recent abdominal aortic aneurysm repair: an absolute contraindication?Systemic thrombolysis in the early postoperative period can cause fatal hemorrhage. Systemic thrombolysis is often considered contraindicated after major vascular procedures; thus, experience with this scenario is limited. A 67-year-old man experienced massive pulmonary embolization after his abdominal aortic aneurysm was repaired with a bifurcated, woven Dacron graft. Because systemic thrombolysis was the only option for our patient's survival, he underwent this procedure with recombinant tis-sue-type plasminogen activator just 2 weeks after the Dacron graft repair of his abdominal aortic aneurysm. After clinical stabilization, abdominal and pelvic computed tomography showed no periprosthetic graft hemorrhage. The successful systemic thrombolysis suggests that this therapy may prove useful in extreme situations.- - - - - - - - - - ranking = 0.75keywords = aneurysm (Clic here for more details about this article) |
