PURPOSE This study retrospectively evaluated ultrasonography-guided (US-guided) percutaneous thrombin injection for the treatment of postcatheterization femoral and brachial artery pseudoaneurysms. MATERIALS AND METHODS Fifty-five patients with postcatheterization femoral artery (n = 53) or brachial artery (n = 2) pseudoaneurysms were treated using US-guided human thrombin (500 IU/mL) injecti...

BACKGROUND The use of thrombolytic therapy in the treatment of thrombosed infrainguinal native arteries and bypass grafts has increased over the years. Main limitation of this treatment modality, however, is the occurrence of bleeding complications. Low intensity ultrasound (US) has been shown to accelerate enzymatic thrombolysis, thereby reducing therapy time. So far, no randomized trials have...

An 81-year-old female presented with a giant aneurysm of the distal anterior cerebral artery (A3) which grew from a small saccular aneurysm to a huge aneurysm within 36 months before manifesting as a mass lesion. The thrombosed portion of the aneurysm showed growth, whereas the aneurysmal cavity did not change in size. Computed tomography and magnetic resonance imaging showed new bleeding in th...

performed to assess the extent of the lesion, the coronary grafts were seen to be patent and 2 aneurysms were visualized in the RCA. The first was in the proximal RCA (described on echocardiography) and the other, in the medial RC, was 17×22 mm in diameter and partially thrombosed (Figures 3A and 3C, arrowheads). In addition, there was a third aneurysm located in the proximal segment of the lef...

Partially thrombosed giant aneurysms are one of the most difficult diseases in the neurosurgical field. We have had 18 of these cases namely, three in vertebral artery, four in basilar artery, four in internal carotid artery, five in middle cerebral artery, and two in anterior communicating artery. Nine aneurysms were clipped, two aneurysms were removed with anastomosis, two cases were treated ...

A 77-year-old woman presented with a rare case of nontraumatic intracavernous internal carotid artery (ICA) aneurysm causing epistaxis. The thrombosed aneurysm was discovered incidentally, and was not treated. However, she suffered massive nasal bleeding 22 months after the initial diagnosis. The lesion was successfully treated by endovascular coil embolization. The present case shows that thro...

Giant basilar artery aneurysms are rarely associated with hydrocephalus. When it occurs the treatment usually addresses the hydrocephalus rather than the aneurysm itself, especially if it is already thrombosed. The treatment options include ventriculoperitoneal shunting and endoscopic third ventriculostomy, which may be related to high complication rates. However, reducing the intracranial hype...

Abstract Pseudoaneurysms of the profunda femoris artery are rare complications femoral fractures, seen especially after orthopaedic interventions for same. We present a case an 89-year-old Caucasian male with left neck femur fracture, repaired dynamic hip screw. He presented to us month later painful swollen thigh and deep vein thrombosis. The patient underwent arterial duplex CT angiogram scan...

We experienced a case of neurological deterioration after decompressive suboccipital craniectomy (DSC) in a patient with a brainstem-compressing thrombosed giant aneurysm of the vertebral artery (VA). A 60-year-old male harboring a thrombosed giant aneurysm (about 4 cm) of the right vertebral artery presented with quadriparesis. We treated the aneurysm by endovascular coil trapping of the right...
