Embolization of a Giant Splenic Artery Aneurysm with Only Proximal Coil Embolization: A Case Report

Traditionally giant splenic artery aneurysms have been treated by surgery. We present the first case report of a patient with a giant splenic artery aneurysm that was successfully treated exclusively by transcatheter technique with only proximal embolization. Potentially, this technique makes more patients eligible for endovascular therapy and reduces operative time.     

The Diagnosis and Treatment of a Mycotic Coronary Artery Aneurysm: A Case Report

Aneurysms of the coronary arteries are rare and are usually associated with atherosclerosis in adults. Mycotic coronary artery aneurysms are exceedingly uncommon and are typically associated with systemic bacteremia, endocarditis, or septic emboli. Literature and data describing the management of mycotic coronary artery aneurysms are limited. This case describes the successful diagnosis of a large right coronary artery aneurysm by transesophageal echocardiogram as well as the successful management of the aneurysm.     

Case Report: A Rare Case of a Giant Right Coronary Artery Aneurysm

We report the case of a 34-year-old female patient with a giant thrombus-filled aneurysm of the right coronary artery presenting as a spherical cardiac mass on echocardiography. The cardiac mass was found to be an 8-cm right coronary artery aneurysm on cardiac magnetic resonance imaging, which also revealed a 3.5-cm proximal left coronary aneurysm and a very small aneurysm at the origin of the obtuse marginal coronary artery. Due to the extent and size of the right coronary aneurysm, a decision for surgical intervention was made. Resection of the right coronary artery aneurysm with vein graft replacement and a bypass to the left anterior descending followed by subsequent exclusion of the aneurysm was successfully performed.     

Inferior Mesenteric Artery Aneurysm: Report of a Case

We present a case of a 42-year-old man with severe abdominal pain and a pulsatile mass in the epigastric area. On CT-Scan there was no aortic ectasia, but a large mass in front of the aorta, on his left side. The diagnosis of the CT-scan was a pseudo-aneurysm of the inferior mesenteric artery. Angio-MR and angiography confirmed the presence of a true aneurysm of the inferior mesenteric artery. The patient had a successful operation with lateral clamping of the aorta and ligation of the aneurysm.     

Extracranial Internal Carotid Artery Mycotic Aneurysm: A Case Report

Mycotic aneurysms of the extracranial carotid arteries (MCAs) are extremely rare. They usually appear as an enlarging pulsatile neck mass with no specific signs and symptoms, and they can lead to severe morbidity and mortality if left untreated. We report a case of a saccular thrombosed MCA in a 68-year-old man, presented as a non-pulsatile enlarging mass. The patient did not have any clinical signs of infection, and he was treated with resection of the MCA and synthetic patch reconstruction of the carotid bifurcation. Postoperative microbial cultures revealed Streptococcus parasanguinis. We review and discuss the literature regarding the clinical presentation, diagnosis and treatment options of MCAs.     

Aneurysm of the Splenic Artery

This paper records an incidence of 10·4% of aneurysm of the splenic artery in 250 consecutive routine post-mortem examinations. Medial degeneration seemed to be the commonest cause of such aneurysms and although a number were associated with other intraabdominal pathology, including portal hypertension, the association may be fortuitous and not causal.     

Giant Coronary Artery Aneurysm With Fistula to the Pulmonary Artery Complicated by Frequent Ventricular Premature Contractions: A Case Report

Giant coronary artery aneurysm with a fistula is a rare condition. The presence of a giant aneurysm imposes considerable health risks.We report a case of a 67-year-old woman who presented with frequent ventricular premature contractions caused by a giant coronary aneurysm arising from a branch of the left anterior descending coronary artery that had a fistulous connection to the pulmonary artery.The patient was referred for cardiac surgery. The giant aneurysm was resected, and the proximal and distal openings were closed directly. The main pulmonary artery was opened longitudinally and the fistula was also closed directly.The patient''s symptoms of frequent ventricular premature contractions disappeared postoperatively as confirmed by electrocardiography.Although the standard therapeutic strategies of the disease are not well established because of the rarity of this condition, our clinical results indicate that the surgical treatment is an effective choice.     

Percutaneous Embolization for Ruptured Ectopic Bronchial Artery Aneurysm: A Case Report

Bronchial artery aneurysm (BAA) is an uncommon disease, and spontaneous rupture of an ectopic BAA can be difficult for diagnosis and life-threatening. This case study describes a 52-year-old man who presented with acute onset of right chest pain, mild tachycardia, and hypertension. The initial diagnosis of acute myocardial infarction was made, and the patient was given nitroglycerin prior to admission to our hospital. However, the patient''s symptoms deteriorated. An enhanced computed tomography scan revealed a ruptured 25-mm diameter mediastinal aneurysm under the tracheal bifurcation when he was admitted to our hospital. Bronchial arteriography further demonstrated a ruptured mediastinal BAA of a bronchial artery originated from the left subclavian artery, supplying the right lobe. Transcatheter artery embolization with polyvinyl alcohol particles and microcoils was performed successfully. The patient''s symptoms were gradually relieved, and without recurrence on 1 year follow-up.This case highlights the rare variation of mediastinal BAA and the role of interventional radiology in diagnosing and treating this critical condition.     

Death Caused by Splenic Artery Aneurysm Rupture during Dobutamine–Atropine Stress Echocardiography: Case Report and Literature Review

A 55-year-old man developed hypertension and acute epigastric pain during dobutamine–atropine stress echocardiography (DASE). Evaluation—including a helical computed tomography (CT) scan of the abdomen and pelvis, as well as surgical exploration—revealed a ruptured splenic artery aneurysm. The patient died, despite multiple surgical interventions and a massive blood product transfusion. Impressively, no deaths from DASE have been previously reported. Additionally, no adverse sequelae during DASE have been reported in patients with an unruptured abdominal aortic aneurysm ≥4 cm in diameter or with an unruptured intracranial aneurysm. We report the first case, to our knowledge, of death caused by splenic artery aneurysm rupture during DASE. Splenic artery aneurysm rupture during DASE, though rare, can lead to death.     

Giant Pulmonary Artery Aneurysm Secondary To Patent Ductus Arteriosus: A Case Report

Aneurysms involving the main pulmonary artery and its branches are rare. Clinical experience is limited, and their management is not well established. We present the case of a 35-year-old male patient with dyspnea and hemoptysis in whom subsequent imaging studies revealed a giant pulmonary artery aneurysm associated with an uncorrected patent ductus arteriosus and Eisenmenger’s syndrome. We chose to treat the patient conservatively with medical management due to the development of Eisenmenger’s physiology while waiting for heart-lung transplantation.     

Endovascular Repair of Innominate Artery True Aneurysm with Extra-Anatomic Revascularization of Right Carotid and Vertebral Arteries — A Case Report

The purpose of this article is to describe the endovascular repair of a large aneurysm of the innominate artery in a patient with a history of chronic renal failure and coronary artery bypass. A 4.5 × 4.8-cm innominate artery aneurysm that extended to the proximal subclavian artery was diagnosed by chest X-ray, computed tomography, computed tomography angiography, and aortic arch angiogram in an 80-year-old man who had problems with his angio access for renal dialysis. Since these aneurysms are potential sources of emboli to the brain, extra-anatomic diversion and revascularization of the right carotid and vertebral arteries were done before endovascular manipulation of the innominate artery. Before discharge, a computed tomography scan showed no evidence of a Type I or major Type II leak. The patient has been doing well as an outpatient. Large innominate artery aneurysms in high-risk patients can be treated successfully by using a combined approach of extra-anatomic revascularization of the right carotid and vertebral artery system, and endovascular repair of the aneurysm.
