Pelvic embolization for treatment of hemorrhage related to spontaneous and induced abortion.

OBJECTIVE: Presentation of outcomes of pelvic arterial embolization for hemorrhage after spontaneous or induced abortion. STUDY DESIGN: We collected case reports of embolization after spontaneous or induced abortion from oral presentations and from members of the National Abortion Federation. RESULTS: Pelvic arterial embolization was performed for 11 women who had hemorrhage after spontaneous or induced abortion, and it was initially successful for all women. One woman ultimately required a hysterectomy after unsuccessful repeated embolization. Prophylactic embolization was done for 8 women who were at risk for hemorrhage from placenta accreta; 4 of these women had subsequent hysterectomies. CONCLUSIONS: Selective pelvic arterial embolization may be a successful treatment for hemorrhage associated with spontaneous and induced abortion. Embolization can be considered before hysterectomy is undertaken for control of hemorrhage. There may be a role for prophylactic catheterization or embolization when there is a risk of severe hemorrhage.

Rational antidepressant selection in the elderly.

Proper selection of antidepressant therapy is of growing importance as new and unique agents are added to the therapeutic armamentarium. Physicians must expend some effort in becoming familiar with the current treatment choices to facilitate selecting agents tailored to the needs of individual patients. The criteria that should be considered in antidepressant selection, assuming equal efficacy at appropriate therapeutic dosages, include propensity of a drug to produce side effects, patient and family history of response to previous antidepressant therapy, pharmacokinetics, ease of administration, drug interaction potential, and emerging data that suggest differential efficacy in specific depressive syndromes.

Presentation of atrial septal defect in the pediatric population.

Our recent experience indicates that patients with a hemodynamically significant atrial septal defect secundum (ASD2) do not necessarily present with classic physical and electrocardiographic (ECG) findings. The purpose of the study was to review the records of patients either receiving a catheter device or undergoing surgical repair for the closure of ASD2 to determine their initial physical and ECG findings. Therefore, we did a retrospective review of 47 consecutive patients who had echocardiographic evidence of a hemodynamically significant isolated ASD2 and who underwent ASD2 closure. Of these 47 patients, the presenting complaints were murmur (n = 36), chest pain (n = 6), seizure (n = 1), stroke (n = 1), syncope (n = 1), Kawasaki's disease (n = 1), and cardiomegaly (n = 1). Charts were reviewed for the evaluation of four abnormal physical findings: hyperactive right ventricular impulse, split fixed second heart sound, systolic and diastolic flow murmurs; and three ECG abnormalities: right axis deviation, right atrial enlargement, and evidence of right ventricular hypertrophy. In all, 30% of patients had either one or no typical physical findings, 18% had normal ECG findings, and 7% had no physical or ECG findings. On physical examination and ECG, the abnormalities due to ASD2 may be too subtle to detect. Although it is well known that variations can occur in the clinical signs and symptoms typical of ASD2, dependence on classical physical and or ECG findings may result in the underdiagnosis of a significant number of patients.
