DescriptionWe present a 50-year-old man with history of end-stage liver disease secondary to hepatitis C, who frequently presents to the hospital with ascites. He recently underwent Trans jugular Intrahepatic Portosystemic Shunt (TIPS) stent placement after becoming resistant to diuresis and large volume therapeutic paracentesis. He presented to the emergency room with altered mental status due to hepatic encephalopathy. On physical exam, he was noted to have a systolic murmur; hence, a transthoracic echocardiogram was ordered. It showed an echo dense ring-like shadow in the right atrium close to intra-atrial septum (figure 1). Transoesophageal echocardiogram was obtained for better visualisation, and it showed a migrated TIPS stent entering the right atrium from the inferior vena cava with its cephalad end close to the intraatrial septum (figure 2). There was no evidence of mechanical complication related to stent migration by echocardiography. The patient declined percutaneous retrieval. He was doing fine on subsequent follow-ups.Stent misplacement and migrations are rare but potentially life-threatening complications of TIPS. Prior case reports in the literature show that stents displaced to distal areas such as right atrium, right ventricle and pulmonary artery. It can also cause conduction abnormalities, valvular damage, perforation and death. [1][2][3] Literature review showed one similar case diagnosed by echocardiography in a 57-year-old male patient, who had cardiac ectopy, where the misplaced stent did not cause acute mechanical complication and was managed in the outpatient setting.
2Our case highlights the role of echocardiography to diagnose such complication of TIPS procedure and evaluate for its consequences. Echocardiography could also help guide the treatment approach including endovascular or surgical stent retrieval.
A 24-year-old female presented with nausea, vomiting and abdominal pain. Physical examination was unremarkable. The patient's laboratory studies showed calcium of 17.2 mg/d, white cell count: 9,000/mcL with a normal peripheral blood smear. The patient had low PTH and PTHrp. She was hydrated, given calcitonin of four units/kg every 12 hours subcutaneously for 24 hours and zoledronate IV 4mg given once, with which calcium levels normalized and symptoms resolved. The patient returned one week later, with bone pain and bruises. Platelet count: 51,000/mcL, WBC count: 9,000/mcL, with lymphocytosis. A peripheral smear showed lymphoblasts. Flow cytometry confirmed precursor B-cell acute lymphoblastic leukemia (ALL) with 43% blasts. Hypercalcemic patients may have blasts at presentation, but can be "aleukemic." Unexplained hypercalcemia with bone pain should lead to the suspicion of ALL, and a bone marrow exam should be performed even without peripheral blastosis to diagnose and treat ALL immediately.
We present a 55-year-old male that developed ventricular fibrillation cardiac arrest in the setting of STelevation acute myocardial infarction with recalcitrant and persistent ventricular fibrillation arrest that was successfully resuscitated with a good neurological outcome. The persistent chest compressions were performed in our intensive care unit with an automated chest compression system. The patient required defibrillations and nonstop chest compressions which were the key factors for his survival. This is an example we should consider in all our intensive care units. It's time for a paradigm shift in replacing the compressor of a code team with an automated system. The out-of-hospital evidence in acute care is compelling to bring this technology that has been proven crucial in transports from hospital areas, ambulances, helicopters, and ships to the inpatient ICU bedside. In ventricular tachycardia and ventricular fibrillation (Vt/Vf), the electrical storm created is the perfect example of the need to have the best compressions to provide the best care possible with the best survival and neurological outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
