Transarterial embolization for control of bleeding in patients with head and neck cancer.

Objective: This study evaluated the efficacy of transarterial embolization for the treatment of tumor bleeding in neck tumors following radiation or chemotherapy.

Study Design: We performed a case series with chart review of 25 patients with clinically suspected tumor bleeding that occurred in the period between August 2003 and April 2007.

Setting: All patients were admitted to and accepted treatment at China Medical University Hospital, Taiwan, R.

Transcatheter arterial embolization in the treatment of maxillofacial trauma induced life-threatening hemorrhages.

Background: Life-threatening hemorrhages with hemodynamic instability are uncommon in patients with sustained maxillofacial trauma, but when they occur, require immediate surgical intervention if conservative treatment fails. This study assessed the effects of transcatheter arterial embolization (TAE) in the treatment of maxillofacial trauma-induced life-threatening hemorrhages.

Methods: From January 2004 to January 2007, eight ambulatory patients admitted for maxillofacial injuries with life-threatening hemorrhaging and hemodynamic instability (systolic blood pressure < or = 90 mm Hg) caused primarily by intractable oronasal bleeding who subsequently underwent TAE were included in this study.

Reappraisal of the management and outcome of emphysematous pyelonephritis.

This study compared the management, prognostic factors and outcomes of patients with emphysematous pyelonephritis (EPN). Twenty-one patients with EPN were studied between September 1996 and August 2005, and were assigned to two groups. Patients in Group 1 received conservative treatment with/without percutaneous catheter drainage (PCD) while patients in Group 2 underwent nephrectomy following medical treatment and PCD.

Emergent transcatheter arterial embolization in hemodynamically unstable patients with blunt splenic injury.

Rationale And Objectives: Splenic preservation is currently the trend for treatment of patients with splenic trauma to avoid complications of splenectomy. This study aimed to evaluate the feasibility of emergent transcatheter arterial embolization (TAE) for hemodynamically unstable patients with blunt splenic injury.

Materials And Methods: In a period of 2 years, 65 patients of blunt splenic trauma were studied.
