Nowadays, compression ultrasonography (CUS) is the gold standard for the routine diagnosis of deep venous thrombosis (DVT). The drawback of CUS is the low sensitivity concerning the diagnosis of isolated pelvic vein thrombosis, especially referring to isolated internal iliac vein and ovarian vein thromboses. Therefore, magnetic resonance (MR) venography has become a valuable alternative. ⋯ Owing to the fact that this thrombus was free floating, surgical removal of the thrombus was scheduled and performed successfully. In some patients it might be important to look for so-called rare causes of pulmonary embolism, even when CUS of the lower limbs does not reveal any DVTs. The diagnostic procedure of choice for these patients seems to be MR phlebography, as iliac and pelvic veins can be evaluated without radiation exposure with this procedure.

Single-segment great saphenous vein (ssGSV) is the conduit of choice in infrainguinal bypass for critical limb ischemia (CLI). The aim of this study was to assess results of other autologous vein grafts and risk factors for graft stenosis development and graft failure. The purpose was also to evaluate outcome of patients with high operative risk undergoing infrainguinal alternative autologous vein bypass for CLI. ⋯ The ssGSV graft is superior to any other autologous vein graft in terms of midterm patency and leg salvage. It also needs less maintenance procedures than AAVGs. Non-ssGSV graft is independent predictor of both graft stenosis development and graft failure. Acceptable patency and leg salvage rates can also be achieved with AAVGs. However, patients with high operative risk and non-ssGSV graft bypass have poor outcome.

Case Reports
Surgical removal of a knotted and entrapped subclavian hemodialysis catheter guidewire.
Many mechanical complications associated with insertion, maintenance, and removal of the hemodialysis catheters have been reported in the literature. A 47-year-old man was consulted to our hospital because of an entrapped hemodialysis catheter guidewire. ⋯ He was discharged home on postoperative day 2 without any complication. Our suggestion is that any abnormal resistance should be immediately evaluated for the presence of any potential knots using the most appropriate imaging technique.

Case Reports
Delayed hypogastric artery pseudoaneurysm following blunt trauma without evidence of pelvic fracture.
Arterial pelvic bleeding caused by bony fragments is a common finding in patients with pelvic fractures after blunt trauma (Durkin et al., Am J Surg 2006;192:211-23). However, arterial injury in the absence of bony fracture is extremely rare, and in the event that it does occur, is immediately discovered on cross-sectional imaging. ⋯ The pseudoaneurysm was successfully treated with selective coil embolization and hematoma evacuation. This study represents only the second reported case of delayed pelvic pseudoaneurysm in the absence of pelvic fracture.

Case Reports
Management of traumatic aortic isthmus rupture in case of aberrant right subclavian artery (arteria lusoria).
To present an unusual case of blunt aortic injury in a 30-year-old male patient with an aberrant right subclavian artery. ⋯ We believe that the hybrid management of such trauma is a feasible, effective, and less-invasive option.
