Summary: Pseudoaneurysm treatment with overlapping stents may be a useful technique to reduce flow and enhance thrombosis in the aneurysmal sac. We treated a pseudoaneurysm of the left carotid artery in a patient with a history of bilateral carotid thromboendarterectomy by placing three stents and overlapping them at the level ...

PURPOSE: To report the need for multiple surgical interventions to treat recurrent aortic aneurysms in a patient with Cogan syndrome. CASE REPORT: A 17-year-old Chinese man with clinical Marfanoid features had a left common carotid artery pseudoaneurysm electively repaired with an autologous saphenous vein graft. Four months later, he presented ...

Renal artery pseudoaneurysms are rare after blunt abdominal trauma. Pseudoaneurysms are caused by decelerating injuries of the renal artery after major falls or car accidents. Patients may be asymptomatic for months or years, and the pseudoaneurysm may expand and rupture before diagnosis or treatment. We report a case of distal ...

A 57-year-old white man with a hypermetabolic right upper-lobe mass underwent treatment with wedge resection. During the immediate postoperative period, a right middle-lobe pulmonary artery pseudoaneurysm developed. After unsuccessful transcatheter coil embolization, fluoroscopically and sonographically guided percutaneous thrombin injection was performed, with complete thrombosis of the pseudoaneurysm.

Conventional surgical repair of ascending aortic pseudoaneurysms following prior cardiac operations is performed with a high operative mortality. We report a 67 year old female patient with an ascending aortic pseudoaneurysm detected 3 years after coronary bypass surgery. The patient was treated with ascending aortic endovascular stent graft placement and ...

The differentiation of left ventricular pseudoaneurysm from true aneurysm is sometimes difficult. Given the propensity for pseudoaneurysms to rupture leading to cardiac tamponade, shock, and death, compared with a more benign natural history for true aneurysms, accurate diagnosis of these conditions is clinically important. Clinical symptoms, physical examination findings, electrocardiograms, ...

BACKGROUND: The StarClose Vascular Closure System (Abbott Vascular, Redwood City, CA) features a nitinol clip that is designed to achieve closure of the femoral arteriotomy access site.

An enlarging pseudoaneurysm of the ascending aorta was found on computed tomography (CT) and magnetic resonance imaging. After a bypass graft procedure for cerebral and cardiac protection, two endoprosthetic cuffs, which ...

There had been no previous reports of ruptured pseudoaneurysm of inferior phrenic artery shortly after blunt abdominal trauma. Traumatic arterial pseudoaneurysms are either iatrogenic or the result of penetrating injuries and one of the sequelae of trauma. Post-traumatic pseudoaneurysm develops at varying time intervals after the initial insult. To our ...

Pseudoaneurysm of the internal mammary artery can be a rare complication of surgery, particularly post-sternotomy, or determined by a direct trauma, usually a stab wound. This report presents a pseudoaneurysm by a stab, diagnosed by chest computed tomography scan performed for hemothorax recurrence. The patient underwent left thoracotomy in third ...

Although uncommon, bleeding following pancreaticoduodenectomy is associated with high mortality. Management generally includes surgical reexploration or, alternatively, transarterial embolization. We report the case of a 62-year-old man who presented with massive upper gastrointestinal bleeding 3 weeks after pancreaticoduodenectomy. Selective coeliac angiography revealed a large pseudoaneurysm involving the proper hepatic artery. ...

Diagnosis of pseudoaneurysm of the aorta or its main branches is a challenge in patients with blunt chest trauma. Computed tomography helps to demonstrate intrathoracic hemorrhage and suspected great vascular injury when a chest radiograph reveals widening of the mediastinum. Aortic angiography remains the gold standard in the determination of ...

Pseudoaneurysm of the inferior epigastric artery complicating ileostomy construction is described in a 25-year-old woman. She underwent total abdominal perineal proctocolectomy with a permanent ileostomy constructed through the right rectus muscle. 15 days later, she abruptly developed significant bleeding through the ileostomy that recurred two more times. Endoscopy performed through ...

We report the case of a 25-year-old female who presented to the emergency department with vaginal bleeding after a cesarean section. A diagnosis of pseudoaneurysm of the uterine artery was established radiologically; however, failure to consider this potentially life-threatening complication of cesarean section resulted in unnecessary morbidity. Doppler sonography and ...

Priapism is an uncommon but serious condition with major long-term sequelae. The commoner, ischemic variety is a medical emergency requiring immediate intervention in order to avoid erectile dysfunction. However,the high flow variety is non-ischemic and the patient may not seek immediate therapy. The options of management for this rare, painless ...

Ruptured mycotic pulmonary pseudoaneurysm is a lethal complication. Emergent surgical repair is usually recommended, but still associated with a high mortality rate. We present a patient in whom mycotic pulmonary pseudoaneurysm was a complication after surgical lobectomy 2 weeks earlier. This patient had suffered from repeated massive hemoptysis. After emergent ...

Pseudoaneurysms in the coronary circulation are an uncommon occurrence that can develop spontaneously in the setting of atherosclerosis or can develop after catheter-based coronary interventions. The natural history, clinical outcome, and optimal therapy for pseudoaneurysms in the coronary circulation are not clearly established. Recent advances in the techniques and technologies ...

Posttraumatic pseudoaneurysms of the brachiocephalic artery are relatively rare.

The pseudoaneurysm was successfully treated by endovascular embolization. To our knowledge, idiopathic rupture of the lumbar artery has been reported in a limited number ...

Pseudoaneurysm of the infrarenal aorta due to Behcet s disease is very rare. We report a case of pseudoaneurysm associated with Behcet s disease in a 17-year-old boy with a recurrent right ventricular thrombus successfully treated with revascularization using arterial homograft patch. Echocardiography examination revealed a right ventricular mass, thought ...

Pseudoaneurysm (dissecting aneurysm) of the membranous septum is a rare occasion. Clinically, aneurysms and pseudoaneurysms not only have the potential to reduce ventricular size, but also can be further complicated by rupture of the aneurysm and by promoting tricuspid insufficiency, aortic valve prolapse, ventricular outflow tract obstruction, and bacterial endocarditis. ...

Complications following cerebrospinal fluid (CSF) diversion procedures are protean. The formation of pseudoaneurysms after the placement of a ventricular catheter as part of a CSF diversion procedure is presumably quite rare. The authors report the case of a child in whom a pericallosal artery pseudoaneurysm developed following the endoscopic insertion ...

BACKGROUND: Traumatic aneurysms of the internal maxillary artery are extremely rare. We report a case of traumatic pseudoaneurysm of the pharyngeal artery, a branch of the internal maxillary artery, presenting with hematemesis and hematochezia.

We describe a case of traumatic pseudoaneurysm of middle meningeal artery in a patient after a head trauma. The aneurysm was associated with epidural hemorrhage and was treated successfully with coil embolization.

Although aneurysmal complications of sickle cell anemia have been described in the intracranial circulation, visceral artery pseudoaneurysms in this disease entity have not previously been reported in the literature. Conventional treatment of visceral pseudoaneurysms has been surgical ligation or resection of the aneurysm. Transcatheter embolization has emerged as an attractive, ...

A 26-year-old drug abuser who presented with sepsis was found to have a pseudoaneurysm in the left vertebral artery. This aneurysm was presumed to be post-traumatic, since the patient reported multiple attempts to inject drugs in the left jugular vein 15 days prior to admission. The pseudoaneurysm was treated effectively ...

Summary: The use of covered stents to treat traumatic carotid artery pseudoaneurysms is increasingly being documented. Adjunctive antiplatelet therapy is mandatory. We present a case of bilateral traumatic carotid artery pseudoaneuryms in which antiplatelet therapy was contraindicated at presentation, thereby dictating alternative treatment with coil embolization alone. Subsequent aneurysmal recurrence ...

We report on the rare and successful surgical treatment of a case of spontaneous rupture of the ascending thoracic aorta resulting in a mimicking pseudoaneurysm. A 72-year-old male who had complained of sudden onset of severe chest pain was admitted to our hospital. Initially, acute type A closing aortic dissection ...

Traumatic pseudoaneurysms of the superficial temporal artery are uncommon. They present to a variety of specialities - orthopaedics, ear, nose and throat, neurosurgery, maxillofacial, plastic surgery, vascular surgery and dermatology. Experience managing these lesions is therefore limited and diluted. We present a case of a giant, traumatic pseudoaneurysm of the ...

Pseudoaneurysms of abdominal aorta after inferior vena cava (IVC) filter placement are uncommon, with associated morbidity and mortality. We report a case in which an abdominal aortic pseudoaneurysm resulted from erosion of a Bird's Nest (Cook, Bloomington, IN) IVC filter into the wall of the abdominal aorta. A 64-year-old woman ...

Since aneurysms in patients with Behçet's disease are often pseudoaneurysmal and adjacent arteries are highly inflammatory, there is not only a risk of rupture but also a high incidence of late surgical complications at anastomotic sites. Furthermore, there is no consensus on perioperative medical therapeutic strategy in patients with active ...

Arterial pseudoaneurysms lack all three layers of the arterial wall and are therefore prone to enlargement. They are common after injuries to the artery in the form of blunt trauma, puncture, or prior surgery. They present frequently with swelling, pain, thrombosis, and rupture and occasionally with infection. Options for repair ...

Renal artery pseudoaneurysms are infrequent and are most often secondary to surgical or percutaneous renal biopsies. Their rupture can cause rapid clinical deterioration by massive haemorrhage. Diagnosis and treatment must, therefore, be rapid. Currently, surgical treatment remains the gold standard in most institutions while paediatric cases of endovascular embolization have ...

PURPOSE: Small areas of blood flow are sometimes seen within an otherwise thrombosed false lumen on computed tomography (CT) scans of intramural hematomas of the aorta. These are blood-filled spaces that, although they have no apparent communication with the true lumen, appear isodense with the aorta on contrast-enhanced CT scans. ...

Endovascular approaches to treat aortic diseases have become an important alternative to open surgical intervention in aortic pathologies. We report a case of an emergency placement of a stent graft in a 16-year-old boy with a contained rupture of an innominate artery pseudoaneurysm. This patient had been previously treated for ...

PURPOSE: Small collections of contrast material are frequently seen within the otherwise thrombosed false lumen of an aortic dissection (AD). These collections can be divided into those without apparent communication with the aortic lumen (ie, pseudoaneurysms) and those with obvious communications (ie, ulcers). The present study was performed to test ...

Formation of carotid artery pseudoaneurysm is uncommon after intensive treatment for head and neck cancer. We encountered a case of postoperative formation of pseudoaneurysm at the left carotid bifurcation in a diabetic man. The risk factors for carotid artery pseudoaneurysm in the patient included diabetes mellitus, previous radiotherapy to the ...

Pulmonary pseudoaneurysms have been described as an unusual complication of Swan-Ganz catheter placement, tuberculosis, bronchiectasis, aspergillomas, and pulmonary hypertension. Untreated, they may lead to life-threatening hemorrhage. Coil embolization to occlude the pseudoaneurysms is the treatment of choice. This report describes a case in which a pulmonary pseudoaneurysm that likely resulted ...

We report a case that was successfully treated for massive lower gastrointestinal (LGI) bleeding due to a recurrent urinary bladder carcinoma. Treatment consisted of combination therapy including embolization of an inferior gluteal artery (IGA) pseudoaneurysm and low-dose arterial vasopressin infusion via a sigmoid artery (SA). A 57-year-old man presented with ...

Rupture of the descending aorta following deceleration trauma is a catastrophic event because it has a high mortality. Prompt surgical treatment is generally considered to be mandatory. However, a few injured patients may leave the hospital with an undiagnosed aortic rupture which may give rise to a chronic pseudoaneurysm. In ...

Behcet's disease (BD) is an autoimmune, multisystemic, and chronic inflammatory disease. Although it affects all systems, involvement of the vascular system is of vital importance. Pseudoaneurysm ruptures in the arteries are the major causes of sudden deaths in BD. Although pseudoaneurysms in aorta and pulmonary arteries are rare, it is ...

Four months after a diagnostic coronary angiography followed by application of a vascular closure device, a female patient presented with an acute femoral pulsing tumor with strong pain in the groin area. There was no prior trauma. Color duplex sonography showed a large pseudoaneurysm of the right femoral artery. In ...

We present a case of traumatic pseudoaneurysm of the middle meningeal artery (demonstrated on CT angiogram) associated with epidural hematoma that spontaneously resolved without treatment. Follow-up CT angiogram and conventional angiogram done 2 weeks later demonstrated complete resolution of the pseudoaneurysm. The literature suggests that these lesions require urgent treatment ...

PURPOSE: To present a case in which thrombin was injected percutaneously to treat an aortic pseudoaneurysm. CASE REPORT: A 63-year-old man developed a large pseudoaneurysm in the abdominal aorta after surgical fenestration and patch aortoplasty for acute type B aortic dissection with malperfusion syndrome. Transcatheter delivery of 1500 units of ...

METHODS: Over 22 months, 25 patients (72% males) with a mean age of 74+/-10 years presented to our institution with a failing infrainguinal bypass. The site of the most significant stenotic lesion was in ...

Summary: We report the imaging findings and endovascular treatment in an unusual case of petrous internal carotid artery pseudoaneurysm due to primary tuberculous otitis. The aneurysm was recognized and ruptured during a surgical intervention for otitis. Successful endovascular treatment of the aneurysm was performed by occlusion of the parent vessel ...

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. Their rupture can cause rapid clinical deterioration by retroperitoneal hemorrhage, and therefore their diagnosis and ...

Gastrointestinal bleeding is a morbid complication of pancreaticoduodenectomy. Determining its etiology is often a daunting challenge in that both common and unusual mechanisms may be operative. Visceral artery pseudoaneurysms, although rare, must be considered in that minimally invasive means are available for effective therapy. Our recent experience with two cases ...
