Endovascular treatment of pulmonary embolism: Selective review of available techniques.

Acute pulmonary embolism (PE) is the third most common cause of death in hospitalized patients. The development of sophisticated diagnostic and therapeutic modalities for PE, including endovascular therapy, affords a certain level of complexity to the treatment of patients with this important clinical entity. Furthermore, the lack of level I evidence for the safety and effectiveness of catheter directed therapy brings controversy to a promising treatment approach.

Ultrasound-guided thrombin injection for treatment of superficial traumatic pseudoaneurysms and associated expanding hematomas: experience in five patients.

Background: Angiography allows for excellent characterization and treatment of traumatic pseudoaneurysms. However, ultrasound-guided thrombin injection for pseudoaneurysm thrombosis allows for radiation-free treatment of superficial pseudoaneurysms and superficial expanding hematomas.

Methods: A retrospective review of 5 patient cases treated under this paradigm was performed following institutional review board approval.

Decreased vascularization of retroperitoneal kaposiform hemangioendothelioma induced by treatment with sirolimus explains relief of symptoms.

Kaposiform hemangioendothelioma (KHE) is a vascular tumor with poor prognosis. We present a child with progressive disability, extreme pain, and autonomic dysfunction due to a retroperitoneal KHE where radiologic characteristics were essential for diagnosis and monitoring of response to therapy. He received sirolimus, and the symptomatology resolved completely.

Vascular anomalies: A pictorial review of nomenclature, diagnosis and treatment.

Vascular anomalies, including vascular malformations and tumors, are frequently straightforward to detect; however, accurate diagnosis and appropriate treatment are often challenging. Misdiagnosis of these lesions can lead clinicians in the wrong direction when treating these patients, which can have unfavorable results. This review presents an overview of the classification systems that have been developed for the diagnosis of vascular lesions with a focus on the imaging characteristics.

Balloon-assisted occlusion of the internal iliac arteries in patients with placenta accreta/percreta.

Background: Placenta accreta/percreta is a leading cause of third trimester hemorrhage and postpartum maternal death. The current treatment for third trimester hemorrhage due to placenta accreta/percreta is cesarean hysterectomy, which may be complicated by large volume blood loss.

Purpose: To determine what role, if any, prophylactic temporary balloon occlusion and transcatheter embolization of the anterior division of the internal iliac arteries plays in the management of patients with placenta accreta/percreta.

Percutaneous gastrostomy for treating dilatation of the bypassed stomach after bariatric surgery for morbid obesity.

Objective: Retrospective analysis was performed to determine the safety and effectiveness of percutaneous gastrostomy for treating distention of the bypassed stomach after gastric bypass for morbid obesity.

Materials And Methods: Eight patients with morbid obesity and Roux-en-Y gastric bypass underwent percutaneous radiologic gastrostomy for postoperative decompression of the bypassed stomach. Four patients underwent gastrostomy on the fourth day after surgery: two in the early postoperative period (< or = 30 days after surgery) and two in the late postoperative period (6, 11 months after the procedure).
