Phlegmasia cerulea dolens (PCD) is a rare condition characterized by a severely swollen, cyanotic, blue extremity due to a large proximal (iliofemoral) deep venous thrombosis extending into the collateral veins. Mortality in PCD ranges 20-40%. Due to severely compromised venous drainage, compartment pressures can rapidly increase 16-fold within 6 h, but rarely result in arterial compromise. ⋯ We present a case of a middle-aged woman with no prior history of deep venous thrombosis, with a blue swollen left leg in intractable severe pain unresponsive to 3 doses of hydromorphone. Her pain was successfully alleviated with IV Lidocaine. Patient was found to have phlegmasia cerulea dolens resulting in compartment syndrome of her left leg. Although the patient initially had no motor function, after catheter-directed thrombolysis and emergent thrombectomy, she regained her motor function and made a full recovery. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Phlegmasia cerulea dolens complicated by severe compartment syndrome is a rare entity. Prompt recognition and treatment are necessary to prevent irreversible limb ischemia and associated morbidity and mortality. IV Lidocaine may be considered as an option for analgesia for such patients.

Electrical storm is defined as three or more sustained episodes of ventricular tachycardia, ventricular fibrillation, or appropriate cardioverter-defibrillator shocks during a 24-h period. These patients are notoriously difficult to manage. We present a case secondary to Chagas disease that was responsive to lidocaine. Although an uncommon presentation, given the large-scale population movement from South America, Chagas has an increased incidence and is an important diagnostic consideration in patients with new onset heart failure, arrhythmia, or electrical storm.

Case Reports
Endovascular thrombectomy using a stent retriever catheter for massive pulmonary thromboembolism.
Acute massive pulmonary thromboembolism (PE) has a high mortality rate of 18%-65%. Along with anticoagulation and thrombolytic therapy, treatment may require a catheter-based thrombectomy or surgical thrombectomy. We report a case of pulmonary thromboembolism treated with a Stent Retriever (Trevo® NXT ProVue Retriever, Stryker, Kalamazoo, MI, USA), which is commonly used to treat stroke. ⋯ The patient was transferred to another hospital on day 64 for rehabilitation. We report the first case of pulmonary artery thrombosis that was successfully recanalized by endovascular treatment with a stent retriever. The stent retriever may be useful as an endovascular treatment device for PE because it is easier to achieve recanalization using this method compared to conventional treatment methods.

We sought to develop a model to measure the acceleration and jerk vectors affecting the performance of High-Quality Cardiopulmonary Resuscitation (HQ-CPR) during patient transport. ⋯ This model reliably measured linear and angular off-balancing vectors experienced during the delivery of HQ-CPR in a moving vehicle. In this preliminary report, compression rate and full recoil appear to be HQ-CPR variables most affected in a moving vehicle.

Case Reports
Acute pulmonary emboli following rebound phenomenon after Nirmatrelvir/Ritonavir treatment for COVID-19.
The return of COVID-19 symptoms after Nirmatrelvir/Ritonavir (Nm/R) treatment is being increasingly reported. Limited evidence suggests most cases of rebound symptoms are mild and do not require further intervention. ⋯ Our case highlights the need to evaluate known complications of SARS-CoV-2 including venous thromboembolism in patients reporting recurring symptoms. Further, cases of severe rebound phenomenon should continue to be reported by clinicians to better appreciate the use of the Nm/R during the Omicron wave and among vaccinated persons.
