Left pulmonary artery in 22q11.2 deletion syndrome. Echocardiographic evaluation in patients without cardiac defects and role of Tbx1 in mice.

INTRODUCTION AND HYPOTHESIS: Patients with 22q11 deletion syndrome (22q11.2DS) present, in about 75% of cases, typical patterns of cardiac defects, with a particular involvement on the ventricular outflow tract and great arteries. However, in this genetic condition the dimensions of the pulmonary arteries (PAs) never were specifically evaluated. We measured both PAs diameter in patients with 22q11.2DS without cardiac defects, comparing these data to a normal control group. Moreover, we measured the PAs diameter in Tbx1 mutant mice.

Endovascular treatment of an anterior tibial artery pseudoaneurysm secondary to penetrating trauma in a young patient. Case report and literature review

We report a case of an 18-year-old woman who developed a delayed pseudoaneurysm of the right anterior tibial artery (ATA), 14 days after a knife accidental trauma. The patient was admitted to our emergency department for acute onset of pain in the right limb after a domestic trauma. At a physical examination, the limb was tense and tender, with a pulsatile mass in the anterior compartment. Femoral, popliteal, and distal pulses were palpable on both limbs. Duplex ultrasound scan (DUS) and computed tomography angiography showed the presence of an ATA pseudoaneurysm.
