Pseudoaneursym Of Lingual ArteryA Rare Case Report

Pseudoaneurysm of the lingual artery is very rarely seen, and it can arise due to various reasons such as trauma, inflammation or even neoplasm. Idiopathic pseudoaneurysm along with being very rare can also be life threatening if they are not diagnosed or treated on time. Our case report describes the idiopathic pseudo aneurysm of sublingual artery which was treated by surgical excision.

A large idiopathic pseudoaneurysm of the popliteal artery: A case report

Introduction. Pseudoaneurysm, also known as a false aneurysm, is a collection of blood which passes through individual layers of the blood vessel or through all layers, but it is retained in the surrounding soft tissues. Case Report. We report presents a 41-yearold patient with a large idiopathic pseudaneurysm of the second segment of the popliteal artery, referred by an orthopedist with a magnetic resonance image of the left leg. The patient?s medical history showed that the pain started three weeks ago, the swelling in the left popliteal fossa about 6 months ago, and a large, painful, non-pulsatile tumefaction was found during the examination, resulting in a 90 degrees flexion contracture of the left knee. The magnetic resonance showed a pseudoaneurysm of the left popliteal artery, and an emergency computed tomography angiography was performed; it confirmed a pseudoaneurysm of the left leg second segment of the left popliteal artery without signs of obliterative diseases. The posterior approach and exposition of the popliteal artery was applied; autovenous graft interposition with a great saphenous vein of the right leg was done. Conclusion. Early diagnosis plays an important role in avoiding temporary and permanent complications. Arterial reconstruction with autovein grafting is a gold standard and a method of choice in the surgery of the pseudaneurysm of the popliteal artery. The temporary setting of occlusive Fogarty catheters reduces damage to the surrounding tissue, accelerates bleeding control, which together shortens the time of surgery.

Idiopathic pseudo-aneurysm of intrathoracic left subclavian artery – a case report

We report an interesting case of left subclavian artery pseudo-aneurysm presenting in a 35 years old male patient with the chief complaints of pain in the back of left chest radiating to left arm for 6 months duration. The chest skiagram showed well defined homogenous round opacity measuring around 3 in. in diameter, involving the left upper zone towards the midline. Computed Tomography (CT) scan thorax showed thickening of soft tissues surrounding the proximal left subclavian artery. CT angiography stamped it as large aneurysmal dilatation of proximal left subclavian artery. On exploratory thoracotomy it was found to be a pseudoaneurysm which was repaired successfully. Pathological examination of the biopsy obtained from the arterial wall did not prove any specific etiology.

Idiopathic Lenticulostriate Artery Pseudoaneurysm Protruding into the Lateral Ventricle: A Case Report

We report a rare case of an idiopathic pseudoaneurysm causing intraventricular hemorrhage (IVH). A 28-year-old man presented with sudden onset of severe headache. He underwent external ventricular drainage for an isolated IVH in the right lateral ventricle. Digital subtraction angiography (DSA) revealed that the aneurysm (7.5×4.5 mm) arose from the distal part of the medial lenticulostriate artery. Following removal of the external ventricular drainage catheter, the aneurysm decreased in size (4.0×2.3 mm). However, follow-up DSA revealed a slightly enlarged aneurysm (4.2×3.2 mm) with morphologic change. The aneurysm was clipped via the interhemispheric transcallosal approach, but postoperative DSA revealed a residual aneurysm sac beside the clips. Given the risk of rebleeding, a second operation was planned for complete resection of the aneurysm. After revised craniotomy and careful dissection of the caudate nucleus, the aneurysm sac was completely resected. Histopathological examination revealed that the aneurysm was a pseudoaneurysm. The patient recovered without any neurological sequel and was discharged.To the best of our knowledge, this is the first reported case of an idiopathic lenticulostriate artery pseudoaneurysm protruding into the right lateral ventricle and causing an IVH that was successfully treated with microsurgical resection.
