“…Pseudoaneurysms usually occur when an arterial puncture site does not adequately seal. A previous study indicated that pseudoaneurysms thrombosed spontaneously in 88% of the cases when pseudoaneurysms were <30 mm [2]. Therefore, in general, observation of small pseudoaneurysms is thought to be reasonable in the absence of severe pain, such as this case.…”

“…In general, pseudoaneurysms are thought to be thrombosed spontaneously. A previous study reported that spontaneous thrombosis of pseudoaneurysm occurred in 88% of cases with small pseudoaneurysms at a mean of 23 days [2]. Another prospective study described that failure of thrombosis was associated with pseudoaneurysms >18 mm and the concomitant use of anticoagulation or antiplatelet agents [3].…”

“…The most serious complication of pseudoaneurysm is rupture, although the exact rate and risk factors are not fully elucidated. Previous studies have indicated that the risk of spontaneous rupture of pseudoaneurysm is related to sizes >30 mm, presence of symptoms, large hematoma, or continued sac growth [2,4].…”

“…Small pseudoaneurysms, especially those with diameters smaller than 2.0 cm, can be treated conservatively and spontaneous thrombosis can be expected 16,17 . Compression guided by ultrasound is a treatment that has variable results and success rates of 50 to 95% and also causes patients discomfort 18 .…”

Introduction: Femoral pseudoaneurysms are a complication that occurs in connection with up to 8% of percutaneous procedures. Of the available treatments, ultrasound guided thrombin injection has a high success rate and is welltolerated by patients. The combination of thrombin and fibrinogen known as fibrin sealant forms a stable clot and can be used to treat pseudoaneurysms, particularly those with complex anatomy and larger size. Objective: To compare the results of treating femoral pseudoaneurysm in two ways: Group T was treated with thrombin alone and Group T+F was treated with fibrin sealant (thrombin+fibrinogen). Methods: A retrospective analysis was conducted of femoral pseudoaneurysm cases treated between January 2005 and December 2012. Results: Twenty-eight patients were treated, 21 with thrombin alone and seven with fibrin sealant. All patients in group T were treated successfully, but only four patients in group T+F were treated successfully (57.1% success rate in Group T+F, p<0.01). The three cases of failure in group T+F needed surgery and in one of these cases the complication was embolization to the femoral bifurcation. The pseudoaneurysms that were treated with fibrin sealant were larger (25 cm 3 in Group T and 57.7 cm 3 in Group T+F, p=0.02) and required larger volumes of thrombin (0.5 mL in Group T and 1.0 mL in Group T+F, p<0.01). There was one complication in Group T and two complications in Group T+F (p<0.01). Conclusions: Irrespective of the small number of cases reviewed, treatment with thrombin alone was superior to treating with fibrin sealant, since it caused few complications and was more effective at correcting pseudoaneurysms.

“…7 Femoral arteriovenous fistulae are also described following percutaneous femoral arterial catheterization. 8 To our knowledge, this is the first report of arteriovenous fistula formation after peripheral venous catheterization for allogeneic peripheral blood progenitor cell collection. It is notable that establishing venous access was neither difficult nor traumatic in this donor.…”

Spontaneous closure of selected iatrogenic pseudoaneurysms and arteriovenous fistulae

Abstract: The natural history of stable pseudoaneurysms and arteriovenous fistulae is benign and frequently results in spontaneous resolution, which allows properly selected patients to be managed without operation.
