Review Case Reports
Surgical repair of a common carotid artery pseudoaneurysm after minor blunt trauma.
Pseudoaneurysms of the common carotid arteries are rare and have been associated with both penetrating and blunt trauma. Intervention is warranted in most cases to avert the sequelae of rupture or embolization. Treatments are tailored to the specific patient on a case by case basis. This report describes an unusual case of common carotid artery pseudoaneurysm after minor blunt trauma and reviews the diagnostic and treatment modalities available.

Comparative Study
Anesthesia-based evaluation of outcomes of lower-extremity vascular bypass procedures.
This report examines the effects of regional versus general anesthesia for infrainguinal bypass procedures performed in the treatment of critical limb ischemia (CLI). ⋯ These results provide no evidence to support the systematic avoidance of general anesthesia for lower-extremity bypass procedures. These data suggest that anesthetic choice should be governed by local expertise and practice patterns.

Comparative Study
Comparison of precuffed expanded polytetrafluorothylene and heparin-bonded polytetrafluorothylene graft in crural bypass.
The purpose of this study was to evaluate early and midterm results of tibial bypasses comparing precuffed expanded polytetrafluoroethylene (PTFE) graft (Distaflo) and heparin-bonded PTFE graft (Propaten) with a distal vein patch. ⋯ Distaflo and Propaten with a distal vein patch in our experience have similar patency and limb salvage results, although further randomized and larger studies are necessary. Postoperative anticoagulation therapy seems better than antiplatelet therapy in terms of patency and limb salvage rate.

Agenesis of the infrarenal segment of inferior vena cava is an uncommon and often asymptomatic congenital abnormality with an approximate incidence of 0.005-1% in the general population. Presentation of this condition as deep venous thrombosis associated with symptoms secondary to thrombosis or hypertrophy of collateral vessels is a rare clinical form. Two cases of this rare form are described, and an analysis of the related literature is presented. ⋯ In a young patient with iliac deep venous thrombosis of uncertain etiology, and particularly in those with atypical associated symptoms (mainly abdominal or neurologic), it is important to investigate congenital vena cava anomalies and carry out diagnostic imaging studies. Anticoagulation therapy is currently considered the best treatment option for this condition, but it should be individualized. The need for long-term anticoagulation should also be assessed in each case.

Case Reports
Concurrent Takayasu arteritis with common variable immunodeficiency and moyamoya disease.
Takayasu arteritis is a rare, chronic form of large vessel vasculitis that characteristically involves the aorta and its branches. Its origin and disease process are currently unknown, although T lymphocytes and, most recently, B cells are thought to play a role. Common variable immunodeficiency (CVID) is a collection of heterogeneous disorders resulting in an antibody deficiency and recurrent infections, and is the most common symptomatic primary immunodeficiency disorder. ⋯ Takayasu arteritis may serve as the main cause of this presentation. The rarity of this case is further accentuated by the presence of moyamoya disease. Finally, the possible disease process and novel treatment of Takayasu arteritis is discussed briefly.
