OBJECTIVE AND IMPORTANCE We present a case of a patient with an ophthalmic artery aneurysm in which the ophthalmic artery originated from the body of the aneurysm, requiring sacrifice of the ophthalmic artery to achieve complete aneurysm obliteration. We awakened the patient intraoperatively to assess optic nerve function after clipping and were able to confirm optic nerve function. Controlled ...

aortopulmonary window (apw) is a rare congenital malformation. it results from an incomplete division between the ascending aorta and the pulmonary artery. we describe a 26-year-old male, who presented with a grade ii exertional dyspnea and palpitations. echocardiography revealed an apw with an ascending aorta aneurysm. he underwent surgery under cardiopulmonary bypass without aortic cross-clam...

BACKGROUND AND PURPOSE Hemodynamic insults at arterial bifurcations are hypothesized to play a key role in intracranial aneurysm formation. This study investigates aneurysm-initiating vascular responses at the rabbit basilar terminus subsequent to common carotid artery ligation. METHODS Nine adult female New Zealand white rabbits were subjected to sham, unilateral, or bilateral common carotid...

A 77-year-old male presented to the emergency department with a 2-day history of increased swelling and pain in the left knee and distal thigh. He was unable to extend the knee without severe pain. On examination, the patient had a large pulsatile mass in the left popliteal fossa and distal thigh. Which of the following is the initial diagnostic test of choice for popliteal artery aneurysm? A. ...

A 53-year-old woman developed a de novo aneurysm after contralateral internal carotid artery occlusion, and another 42-year-old woman developed a de novo aneurysm after contralateral vertebral artery occlusion. Both patients experienced a rapid development of de novo aneurysm formation, 6 and 9 months, respectively. The development of de novo aneurysm on the contralateral artery after parent ar...

Aneurysm of the pulmonary artery is a rare condition in animals, and to our knowledge it has never been reported association with neoplasia. This report describes case an adult female sheep “Churra Galega Bragançana” breed aneurysm associated lung cancer (ovine adenocarcinoma).

INTRODUCTION Collateral muscular artery aneurysm is exceedingly rare. We report the first case of subscapular artery aneurysm in a patient with type 1 neurofibromatosis and ipsilateral chronic subclavian artery occlusion. CASE PRESENTATION A 74-year-old Caucasian woman with a medical history of type 1 neurofibromatosis, presented a sudden left pectoral mass, later diagnosed as a ruptured aneu...

Coronary artery fistulas are a very rare cardiac anomaly. The reported Incidence of coronary artery fistula is 0.10.2% in all patients undergoing coronary angiography [1]. 26% of the patients with coronary artery fistula have associated coronary artery aneurysm. Giant coronary artery aneurysms with diameter exceeding 50 mm are extremely rare. As the aneurysm enlarges, complications related to v...

A hypertensive 69-year-old man presented with an incidentally discovered non-ruptured aneurysm of the persistent primitive olfactory artery (POA). The POA originates at the terminal portion of the internal carotid artery, runs along the olfactory tract anteriorly toward the crista galli, and forms an acute angle with the distal anterior cerebral artery. The aneurysm was located at this characte...

We report a rare case of aneurysm of splenic artery arising anomalously from the superior mesenteric artery (SMA). The aneurysm was treated successfully by coil embolization of the splenic artery distal to aneurysm and then deploying a stent graft in the SMA. A combination of stent graft and coil embolization for the treatment of aberrant splenic artery aneurysm has been reported only once. We ...
