[Management of popliteal artery pseudoaneurysms as a result of limb trauma and orthopedic surgery or associated with osteochondromas]. / Prise en charge des faux anévrismes de l'artère poplitée associés aux ostéochondromes et ceux dus aux traumatismes des membres ou secondaires à la chirurgie orthopédique.

Most published articles regarding popliteal artery pseudoaneurysms (PAPs) are case reports and in English language literature. In this context, no study with robust data was previously published. The exact epidemiology of these APs is not well-known and their management is not yet codified. We wanted to summarize the current knowledge on diagnostic and therapeutic features of PAPs as a result of limb trauma and orthopedic surgery or associated with osteochondromas. An electronic research on MEDLINE and EMBASE between 1953 and March 2015 was performed; using the key words "popliteal pseudoaneurysm". The referenced articles were selectively read and this systematic review included 116 articles. Patient demographics; clinical presentations; diagnostic and therapeutic features were reviewed. In sum, 122 cases were analyzed. Overall young adult (average age=30.48±21.25 years old) represented the majority of the affected population with a masculine preponderance (79%). The main etiologies included femoral exostosis (63%), followed by the orthopedic surgery (25%) and direct trauma into the knee (10%). Painful swelling (44%) and/or pulsatile mass (39%) represented the most commonly presenting symptoms. The commonest radiological investigations used included arteriography (49%) and CTA (27%). The treatment was open surgical repair (85%) or endovascular stenting graft (14%). Post-therapeutic courses were often uneventful (98%). The morbidity rate was low at about 2%. The treatment of direct post-traumatic PAPs was usually open surgical repair (83%) with saphenous vein grafting. Endovascular stenting may be an ideal option for managing PAPs following orthopedic surgery (88%). Open surgery for vascular repair and maximum exostectomy must be undertaken concomitantly in the setting of APs associated with osteochondromas.

Traumatic False Aneurysm: Report of Two Cases / 대한정형외과학회잡지

False aneurysm is one of the complications of untreated arterial injury. Most traumatic aneurysms in the extremities are false, and they are usually caused by penetrating trauma. The pathogenesis of false aneurysm is initiated by a damaged artery that allows hemorrhage into surrounding soft tissue, an encapsulated hematoma is then formed, which undergoes organization, with invasion of fibrin and con-nective tissue, and the endothelialization of its central cavity, which communicates with the arterial defect, forming the false aneurysm. We experienced two cases of traumatic false anerysm of a left anterior tibial artery and a right radial artery, which were treated successfully by end-to-end anastomosis in the former and a saphenous vein graft in the latter.

Traumatic False Aneurysms of the Upper Extremity: 2 Case Reports / 대한정형외과학회잡지

An aneurysm in the upper extremity is rarer than in the lower extremity, and a traumatic false aneurysm is very rare. We encountered two patients with a traumatic false aneurysm in the upper extremity. The first case developed from a posterior interosseous artery injury after an internal fixation using a plate and circumferential wiring for a comminuted fracture of the proximal shaft of radius associated with a dislocation of the left elbow joint. This patient was managed by excision of the false aneurysm, and ligation of the artery. The second case developed from a radial artery catheterization on the left wrist. This was managed by excision of the false aneurysm and an end-to-end anastomosis and resulted in the disappearance of the false aneurysm and a good vascular patency. We report two rare cases of traumatic false aneurysm in the upper extremity and a review of the literature.

Traumatic False Aneurysm: Two Cases of Traumatic False Aneurysm of the Superficial Temporal Artery

Two cases of iatrogenically induced false aneurysm of the superficial temporal artery are presented. One patient showed partially filled aneurysmal sac, 1x1 cm sized, on the main trunk of left superficial temporal artery by external carotid artery angiography. Another patient showed aneurysmal dilatation, 3x2 cm sized, of the superficial temporal artery with direct injection of Urograffin into the pulsatile mass. Aneurysm excision is indicated to reduce the risk of hemorrhage from the subsequent head trauma, to relieve headache, and for any cosmetic defect. The authors have reviewed the literature and discussed the incidence, classification, pathogenesis, clinical and angiographic diagnosis, differential diagnosis, and treatment.

Traumatic Cerebral Aneurysm: A Case of Traumatic False Aneurysm of the Superficial Temporal Artery

A case of iatrogenic false aneurysm of the superficial temporal artery is presented. Direct injection of Urograffin into the pulsatile mass showed aneurysmal dilatation, 3x2cm sized, of the superficial temporal artery. Aneurysm excision is indicated to reduce the risk of hemorrhage from the subsequent head trauma, to relieve headache, and for any cosmetic defect. The authors have reviewed the literature, and discussed the incidence, classification, pathogenesis, clinical and angiographic diagnosis, differential diagnosis, and treatment.
