Andexanet alfa and four-factor prothrombin complex concentrate for reversal of apixaban and rivaroxaban in patients diagnosed with intracranial hemorrhage.

Limited data exists regarding the clinical outcomes of andexanet alfa and four factor prothrombin complex concentrate (4F-PCC) for reversal of apixaban or rivaroxaban in the setting of intracranial hemorrhage (ICH). The objective of this study was to evaluate clinical outcomes of 4F-PCC and andexanet alfa for reversal of ICH associated with oral factor Xa inhibitors. This was a retrospective, single-center, case series evaluating hemostatic efficacy of patients receiving andexanet alfa) or 4F-PCC for reversal of apixaban or rivaroxaban after ICH. Secondary endpoints included in-hospital mortality, thrombotic complications, timing of reversal agents, intensive care unit and hospital length of stay, patient disposition, and 30-day readmission rate. During the study period, 21 patients received andexanet alfa and 35 received 4F-PCC. Hemostatic efficacy occurred in 64.7% of patients receiving andexanet alfa and 54.8% of receiving 4F-PCC. Thirty-day all-cause mortality was 45.2% for 4F-PCC and 30% for andexanet alfa. Thrombotic events were higher with 4F-PCC (31.4%) compared to andexanet alfa (14.3%). Median time from presentation to administration of reversal agent was 2.67 [1.75-4.13] hours with andexanet alfa and 1.73 [1.21-3.55] hours with 4F-PCC. Discharge to skilled nursing facilities and 30-day readmission were similar between groups. In this cohort, reversal with andexanet alfa and 4F-PCC differed in terms ofhemostatic efficacy and thrombotic events after ICH in patients anticoagulated with apixaban or rivaroxaban.

Surgical management of ovarian carcinosarcoma with inferior vena cava extension into the right atrium.

Gynecological carcinosarcomas are aggressive tumors with rare occurrence and high rates of metastases. We present the case of a 49-year-old woman with vaginal bleeding and abdominal distension who was found to have a large ovarian carcinosarcoma invading the gonadal vein and inferior vena cava (IVC) and extending into right atrium (RA). She underwent gynecologic tumor resection, IVC cavotomy and en bloc resection of tumor/thrombus through the RA. Use of intraoperative transesophageal echocardiography helped assess extent and mobility of mass in the RA to guide surgical approach. This case posed unique challenges with regard to management of induction, hemodynamics and coagulopathy.

Accidental venous and dural puncture during epidural analgesia in obese parturients (BMI > 40 kg/m2): three different body positions during insertion.

STUDY OBJECTIVE: To assess the frequency of blood vessel punctures in morbidly obese parturients [body mass index (BMI) > 40 kg/m(2)] during epidural catheterization, in three different body positions. DESIGN: Prospective, randomized study. SETTING: Delivery room of a university-affiliated hospital. PATIENTS: 347 obese parturients (BMI > 40 kg/m(2)) undergoing continuous epidural analgesia during labor. INTERVENTIONS: Patients were randomized to undergo epidural catheterization in the sitting, lateral recumbent horizontal, or lateral recumbent head-down positions. MEASUREMENTS AND MAIN RESULTS: A lower frequency of epidural venous cannulation was noted when this procedure was performed in the lateral recumbent head-down position (4.8%) than in the lateral recumbent horizontal (11.6%) or sitting position (18.3%) (P = 0.001). Frequency of accidental subarachnoid puncture did not differ significantly (2.5%, 2.6%, and 3.7%), respectively. CONCLUSION: Adoption of the lateral recumbent head-down position for the performance of lumbar epidural blockade in labor at term reduces the frequency of lumbar epidural venous puncture in obese parturients (BMI > 40 kg/m(2)).

The lateral recumbent head-down position decreases the incidence of epidural venous puncture during catheter insertion in obese parturients.

PURPOSE: The unintentional and unrecognized cannulation of an extradural vein is a potentially serious complication of an epidural anesthetic. The present study was undertaken to assess the incidence of blood vessel puncture related to epidural catheterization in three different body positions, in a cohort of morbidly obese parturients, following the completion of a similar study published in 2001 from which such parturients were excluded. METHODS: The study was conducted in 450 (three groups of 150) morbidly obese, obstetric patients undergoing continuous epidural analgesia during labour. Epidural catheterization was performed on patients randomized to the sitting, lateral recumbent horizontal, or lateral recumbent head-down position. RESULTS: There was a lower incidence of vessel cannulation when this procedure was performed in the lateral recumbent head-down position [1.3%; body mass index (BMI): 37.0] than in the lateral recumbent horizontal [12.9%; BMI: 38.0] and in the sitting position [12.0%; BMI: 38.0]. The incidence of accidental subarachnoid puncture was 2%, 1.3% and 2% respectively, in these same positions. CONCLUSION: Adoption of the lateral recumbent head-down position for the performance of lumbar epidural blockade, in labour at term, reduces the incidence of lumbar epidural venous puncture in these obese parturients.
