BACKGROUND Popliteal fossa pseudoaneurysms as a result of trauma are not uncommon. However, spontaneous pseudoaneurysms as a result of non-traumatic rupture of posterior tibial artery (PTA), anterior tibial artery (ATA), or tibioperoneal trunk (TPT) artery segment are extremely rare. We report a case of spontaneous popliteal fossa pseudoaneurysm resulting from spontaneous avulsion of the ATA an...

UNLABELLED Popliteal artery aneurysms are frequent and may lead to thromboembolic events and limb loss. PURPOSE To evaluate clinical and ultrasonographic follow-up of patients who underwent exclusion of a popliteal artery aneurysm using the technique proposed by Edwards. METHODS Data of all patients who underwent surgery to repair a popliteal artery aneurysm at Hospital das Clinicas, the Sã...

Soft-tissue defects caused by radiation injury are a challenging task for the reconstructive surgeon, due to the extent of the soft-tissue damage and the associated injuries of the local blood vessels and bone tissue. We present the application of the versatile deep inferior epigastric perforator (DIEP) flap for the coverage of an extended lateral thigh soft-tissue defect after the surgical res...

Background: Due to the increasing number of surgical techniques used nowadays on the knee joint, the importance of the knowledge of the branching pattern of the vessels neighboring the joint becomes very significant. Anomalies of vascular patterns near the knee joint particularly the popliteal vessels, are therefore noteworthy in understanding the atypical clinical findings encountered while de...

BACKGROUND To retrospectively review the bilateral venous system within the popliteal fossa to evaluate the types of variations and their frequency seen in venous anatomy. MATERIALS AND METHODS During routine dissection of formalin-fixed cadavers, a retrospective review of 32 bilateral (64 limbs) lower limbs obtained from adult donors was performed. Deep veins present in the popliteal fossa w...

INTRODUCTION Cases of true mycotic popliteal artery aneurysm are rare. Presentation is variable but invasive and non-invasive investigations collectively facilitate diagnosis and guide operative procedures. Definitive treatment generally utilizes surgical intervention with excision and reconstruction using autologous vein graft. Prolonged targeted antibiotic therapy is an important adjuvant. ...

BACKGROUND There is a lack of information about the possibility of transfer of the long head of the biceps femoris (LHBF) musculocutaneous flap to the knee area. We discuss the use of the LHBF musculocutaneous flap to treat refractory ulceration at the popliteal fossa and the results of a preliminary study investigating the anatomical possibility of transferring this flap to the popliteal regio...

PURPOSE To study the anatomy of the middle genicular artery and thus mitigate the risk of vascular injury in knee surgery. METHODS The course, anatomic relations, and variations of the middle genicular artery in 8 cadavers (4 men and 4 women) were studied. RESULTS The middle genicular artery originated from the anterolateral surface of the popliteal artery in the popliteal fossa, 3 to 5 cm ...

IN 1953 Gifford, Hines, and Janes' clearly demonstrated the high incidence of serious complications in patients with untreated aneurysms of the popliteal artery. They pointed out that arteriosclerosis was present in almost all the 100 popliteal aneurysms that they studied and that the aneurysms were not infrequently bilateral or multiple. Popliteal aneurysms are seen predominantly in men more t...
