Seurat Spleen: A Pathognomonic Sign in Angiography.

Splenic injury commonly occurs following abdominal trauma and can result in severe complications and death if it goes unrecognized. The Seurat spleen is a term used to describe the angiographic appearance of splenic injury following blunt trauma, given its resemblance to the pointillistic artwork of French neo-impressionist Georges Seurat. We present a case of a 43-year-old man who presented following a motor vehicle collision and was found to have multiple punctate foci of contrast extravasation in the spleen consistent with the Seurat spleen angiographic sign. This angiographic pattern can be used as a pathognomonic sign to identify splenic injury, with early identification crucial to preventing further complications of the injury.

Vascular Closure Devices: Technical Tips, Complications, and Management.

Vascular closure devices (VCDs) are used to obtain hemostasis at the vascular access site while limiting the need for manual compression. They have gained significant popularity since their introduction in the mid-1990s. In the past 20 years, there has been a multitude of different devices introduced with various mechanisms of action. Manual compression remains the gold standard but can be very time consuming and painful for the patient. VCDs are advantageous in that they can reduce time to hemostasis and patient recovery and improve patient comfort. However, a large number of catheter-based procedures are performed without these closure devices owing to lack of operator familiarity, risk of complications, and cost. Most VCDs are approved for arteriotomies between 5 and 8F, with 1 device approved for up to 21F. Major complications include infection and limb ischemia. This article provides an update on currently approved VCDs, a brief overview of the literature, and our institutional experience with these devices.

Placenta previa-accreta: risk factors and complications.

OBJECTIVE: The purpose of this study was to identify risk factors and complications of placenta previa-accreta (PA). STUDY DESIGN: Patients with placenta previa (n = 347) delivered over 20 years were reviewed, divided into PA (cases, n = 22) and no accreta (controls, n = 325), and compared. RESULTS: Cases were older with a higher incidence of smoking and previous cesarean delivery (CS). Grandmultiparity, recurrent abortions, anterior/central placentae, and low socioeconomic status were similar. PA incidence increased with the number of previous CS: 1.9%, 15.6%, 23.5%, 29.4%, 33.3%, and 50.0% after 0, 1, 2, 3, 4, and 5 previous CS, respectively. Hypertensive disorders (odds ratio [OR] 13.9, 95%CI 2.1-91.2], P = .006), smoking (OR 3.4, 95%CI 1.1-10.2, P = .031) and previous CS (OR 7.9, 95%CI 1.7-37.4, P = .009) were selected by the stepwise logistic regression analysis as predictors of PA. Cases had a longer hospital stay, a higher estimated blood loss, and need for transfusion. Cesarean hysterectomy and hypogastric artery ligation were only performed in PA cases. The 2 groups had a similar delivery gestational age and neonatal outcome. CONCLUSION: Hypertensive disorders, smoking, and previous cesarean are risk factors for accreta in placenta previa patients. Placenta previa-accreta is associated with higher maternal morbidity, but similar neonatal outcome compared with patients with an isolated placenta previa.
