Time to hemostasis after traction removal of tunneled cuffed central venous catheters.

Purpose: Many patients undergo placement of tunneled cuffed central venous catheters (TCCVCs) for indications including administration of medical therapy and hemodialysis. They are removed when no longer needed or if there is a device complication. There is no consensus regarding the necessity of routine preremoval coagulation studies or platelet count, so this study was performed to determine if abnormal coagulation status affects the time to hemostasis (TH) after traction removal of TCCVCs.

Renal interventions after abdominal aortic aneurysm repair using an aortic endograft with suprarenal fixation.

Background: Our aim was to determine whether suprarenal fixation in endografts compromises renal artery (RA) flow and whether subsequent RA intervention is precluded by the stent struts.

Methods: Prospectively acquired data from 104 patients with endovascular aneurysm repair (EVAR) of an abdominal aortic aneurysm using the Zenith endograft (Cook, Inc., Bloomington, IN) were analyzed.

Severe thrombocytopenia due to hypersplenism successfully treated with partial splenic embolization in preoperative management.

Hypersplenism is a known complication of portal hypertension secondary to cirrhosis of the liver. Although thrombocytopenia secondary to hypersplenism does not cause clinically significant hemostatic defect, it may need to be addressed in selective circumstances, such as preoperative preparation for a surgery. This report describes a 30-year-old male with a history of cirrhosis of the liver and hypersplenism who had a recurrence of craniopharyngioma.

Suspected acute pulmonary embolism: evaluation with multi-detector row CT versus digital subtraction pulmonary arteriography.

Purpose: To determine diagnostic accuracy of four-channel multi-detector row computed tomography (CT) in emergency room and inpatient populations suspected of having acute pulmonary embolism (PE) who prospectively underwent both CT and pulmonary arteriography (PA).

Materials And Methods: Patients referred for PA to assess suspected PE were eligible. Institutional review board approval and written informed consent were obtained.

Embolization of large gastric varices using vena cava filter and coils.

A 40-year-old male with alcoholic cirrhosis and portal hypertension presented with acute variceal hemorrhage. Abdominal CT scan and endoscopy revealed large gastric varices. The patient underwent a TIPS procedure.
