Acute limb ischemia as sole initial manifestation of SARS-CoV-2 infection.

We present the case of a patient with acute upper limb ischemia as the sole initial manifestation of severe acute respiratory syndrome associated with coronavirus disease 2 infection, without concomitant respiratory symptoms or pneumonia. Viral infection presumably precipitated the patient's thromboembolic event, causing multifocal vascular occlusions. This case illustrates that coronavirus disease-19 must be considered in the differential diagnosis of patients presenting with signs or symptoms of coagulopathy, even in the absence of respiratory symptoms.

Early Outcomes in the ROADSTER 2 Study of Transcarotid Artery Revascularization in Patients With Significant Carotid Artery Disease.

Background And Purpose: Transcarotid artery revascularization (TCAR) is comprised of carotid artery stent placement with cerebral protection via proximal carotid artery clamping and reversal of cerebral arterial flow. The aim of the present study was to evaluate the safety and efficacy of TCAR performed by a broad group of physicians with variable TCAR experience.

Methods: The ROADSTER 2 study is a prospective, open label, single arm, multicenter, postapproval registry for patients undergoing TCAR.

Cost-effective analysis of transjugular intrahepatic portosystemic shunt versus surgical portacaval shunt for variceal bleeding in early cirrhosis.

Upper gastrointestinal hemorrhage carries significant morbidity and mortality in patients with portal hypertension and cirrhosis. The optimal prevention strategy for rebleeding in these patients remains controversial with respect to the safety and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) versus a portocaval surgical shunt (PC). We sought to determine the long-term cost-effectiveness of these two treatments.

Open-cell versus closed-cell stent design differences in blood flow velocities after carotid stenting.

Objective: The differential effect of open-cell vs closed-cell stent design configuration on carotid velocities detected by duplex ultrasound (DUS) imaging has not been established. To identify possible stent design differences in carotid velocities, we analyzed DUS studies obtained before and immediately after carotid artery stenting (CAS).

Methods: In a series of 141 CAS procedures performed during a 3-year period, data from the first postinterventional DUS images and carotid angiograms were evaluated for each patient.

Intraoperative parathyroid hormone assay: an accurate predictor of symptomatic hypocalcemia following thyroidectomy.

Hypothesis: Intraoperative parathyroid hormone (IOPTH) assay is useful for predicting symptomatic hypocalcemia following total thyroidectomy.

Design: A prospective study of 30 patients undergoing total thyroidectomy with IOPTH levels obtained following skin closure and ionized calcium (Ca2+) levels obtained 6 hours postoperatively and on postoperative day 1. All patients were evaluated for symptoms of hypocalcemia.
