Abruption of Abdominal Pregnancy Following Blunt Trauma

Abdominal pregnancy represents a rare subset of ectopic pregnancy with a reported incidence around one per 10,000 live births. It is associated with high fetal and maternal morbidity and mortality. In this case, we describe a 25-year-old primigravida female who presented as a trauma activation with acute hypotension following blunt trauma to the abdomen and who was found to have a viable abdominal pregnancy with placental abruption. Given hypotension and non-reassuring fetal heart tones, the decision was made to take the patient to the operating room for emergent exploratory laparotomy and cesarean section. The placenta was severely adhered to a portion of small bowel, the appendix, and the right adnexa with an approximate 20% abruption. The placenta and adhered structures were removed. In pregnant patients presenting after blunt trauma with free intraabdominal fluid and hypotension, abdominal pregnancy with abruption should be considered as an unlikely differential.

Inferior Vena Cava Filter Occlusion Causing Phlegmasia Alba Dolens

Phlegmasia alba dolens is a rare sequela of acute extensive venothrombus of the iliofemoral segments. Rarely, phlegmasia alba dolens can also result from clotted inferior vena cava filter. A 39-year-old with protein S deficiency, and prior inferior vena cava filter placement after remote trauma presented to the emergency department with progressive bilateral lower extremity pain and swelling. Venous duplex revealed extensive bilateral deep vein thromboses from the external iliac veins to popliteal veins, as well as thrombophlebitis of the left great saphenous vein. Venography confirmed patency of the suprarenal vena cava with abrupt occlusion of the infrarenal segment at the level of the inferior vena cava filter. The filter was removed followed by endovascular thrombectomy and adjunctive venoplasty. The patient progressed well and discharged on therapeutic anticoagulation. This case illustrates that a staged endovascular approach may be utilized for acute on chronic caval thrombosis and filter removal.

Saddle Pulmonary Embolus and Simultaneous Common Carotid and Subclavian Artery Emboli

A patent foramen ovale (PFO) is present in 27-35% of the population. Right to left cardiac shunts predispose patients to arterial emboli in the presence of venous thromboembolisms. Paradoxical embolus should be suspected in patients with deep venous thrombosis (DVT) and arterial emboli. A 45-year-old man with hypercoagulability and history of DVT presented with a week-long history of chest pain, shortness of breath, and left arm numbness. Imaging showed a saddle pulmonary embolus (PE) and emboli involving the aortic arch, left common carotid, and left subclavian artery. The patient proceeded with an endovascular thrombectomy of the pulmonary artery, followed by open thrombectomy. Echocardiogram confirmed a right to left intra-cardiac shunt consistent with a PFO. Paradoxical emboli are rare manifestations of venous thromboemboli in patients with right to left intra-cardiac shunts. Patients should be evaluated for these to help prevent further manifestations.

Embryologic considerations of diphallus and associated anomalies

Two patients, 1 adult and 1 infant, with complete duplication of the penis are described. The adult had a single bladder, a bifid scrotum, a low abdominal wall hernia, separation of the symphysis pubis, bilateral inguinal hernias, rectal prolapse, bilateral vesicoureteral reflux and bilateral staghorn calculi. The infant had duplication of the bladder, hypoplasia of the left kidney, lumbosacral anomalies, a hypoplastic left lower extremity, an imperforate anus, a infraumbilical wall hernia and separation of the symphysis pubis. A survey of the anomalies accompanying the 2 main types of diphallus (shaft and glans, and glans alone)showed that there was a preponderance of anomalies of posterior structures such as colon, bladder and spine in the shaft and glans diphallus, and a higher incidence of isolated exstrophy of the bladder in diphallus of the glans alone. The embryogenic implications of these findings are discussed.
