Venous thromboembolism is a common cause of death. Acute massive pulmonary embolism (PE) is life-threatening and may require vigorous more invasive treatment. ⋯ Systemic thrombolytic therapy, catheter-directed thrombolysis, percutaneous embolectomy, and more recently, percutaneous thrombus fragmentation techniques with a multitude of devices are now available to treat the most severe cases of massive PE. Successful treatment of PE includes implementation of a treatment protocol and the use of associated techniques and devices.

To determine complications after transcatheter embolization for blunt splenic injury as recognized with computed tomography (CT). ⋯ Infarcts are common after splenic embolization. Gas may be present within an infarct after embolization with Gelfoam; however, the presence of air/fluid level is a better predictor of abscess.

Long-term outcome of embolotherapy and surgery for high-flow extremity arteriovenous malformations.
To assess the long-term efficacy of embolotherapy in combination with surgery for management of symptomatic high-flow arteriovenous malformations (HFAVMs) of the lower and upper extremities. ⋯ LE-AVM with diffuse involvement of all three trifurcation arteries ultimately required amputation because of recurrence of symptoms after technically and clinically successful embolotherapy. Cyanoacrylate embolotherapy alone or in combination with surgical resection of the AVM provided excellent long-term palliation in patients with UE-AVM.

Venous thrombosis associated with the placement of peripherally inserted central catheters.
Peripherally inserted central catheters (PICCs) have become an essential component of the management of an increasing number of patients, including patients who may require hemodialysis. Reported symptomatic venous thrombosis rates associated with PICC lines are based on clinical signs and symptoms and range from 1% to 4%. The purpose of this study is to evaluate the true rate of thrombosis of upper extremity veins after the placement of PICCs and the potential impact on future access in hemodialysis patients. ⋯ There is a relatively high rate of venous thrombosis associated with PICCs, particularly cephalic thrombus. Because of the high rate of thrombosis associated with these catheters, an alternative mode of access should be considered in current or potential hemodialysis patients. All patients with a history of PICC line placement requiring dialysis access should undergo upper extremity venography prior to the placement of permanent access.
