background the identification of the dorsal sector of the liver and its detailed vascular anatomy is of primary importance for surgical practice and segmental transcatheter arterial chemoembolization. objectives this study aimed to investigate the feeding arteries of tumors in dorsal sector of the liver. patients and methods computed tomography (ct) and digital subtraction angiography (dsa) ima...

BACKGROUND Aneurysms of the external carotid artery and its branches are rare. METHODS We present an extremely rare case of pseudoaneurysm of the lingual artery secondary to concurrent intra-arterial chemotherapy via the superficial temporal artery for advanced tongue cancer. RESULTS The patient developed sudden and significant oral bleeding from the left tongue base 10 weeks after the comp...

Renal artery aneurysms and pseudoaneurysms are an uncommon clinical problem with a low incidence rate. They are abnormal dilatations of the vessel lumen with some different natures. However, the rupture of an aneurysm and pseudoaneurysm is the most dreaded complication because it causes death of the patient. There are many causes of renal artery aneurysm and pseudoaneurysm, including Behçet's d...

Posttraumatic pseudoaneurysms of the lateral plantar artery are rare. We report the case of a 31-year-old woman with a painful pseudoaneurysm of the lateral plantar artery resulting from a deep plantar cut injury. The pseudoaneurysm was successfully treated by performing a transarterial “frontdoor-backdoor” coil embolization technique, which is a minimally invasive alternative to conventional l...

BACKGROUND Splenic artery aneurysm and pseudoaneurysm are rare pathologies. True aneurysms are usually asymptomatic. Aneurysm rupture occurring in 2-3% of cases results in bleeding into the lesser sack, peritoneal space or adjacent organs typically presenting as abdominal pain and hemodynamic instability. In contrast, pseudoaneurysms are nearly always symptomatic carrying a high risk of rupture...

Carotid artery injuries with pseudoaneurysm are uncommon but associated with central neurologic dysfunction. We present a case of posttraumatic pseudoaneurysm of the right common carotid artery treated by implantation of a covered stent. A 44-year-old woman with multiple injuries after fall from height presents a small dissection flap of the right common carotid artery (RCCA) on the initial com...

Blunt trauma to the right proximal subclavian artery is uncommon and tends to be associated with pseudoaneurysm formation. We report a patient with right proximal subclavian artery pseudoaneurysm after blunt chest trauma following a motor vehicle accident. The condition was successfully treated with a combined insertion of a covered stent and carotid-carotid bypass as a hybrid procedure. Duplex...

Popliteal artery pseudoaneurysm is uncommon. They usually result from penetrating or blunt trauma, arterial reconstructive surgery, invasive diagnostic or surgical orthopedic procedures. They can cause arterial thrombosis and limb ischeamia. We report a 53 year old Chinese gentleman with popliteal artery pseudoaneurysm who presented with right lower limb numbness and paralysis in toes extension...
