BACKGROUND Superior vena cava (SVC) syndrome is a major complication that occurs when a growing lung malignancy compresses the SVC extrinsically. Current treatment options include radiotherapy or chemotherapy to shrink the tumor or endovascular stenting of the SVC to restore flow. Herein, we report a case series treated in a single institution to demonstrate the safety, effectiveness, and outco...

S uperior vena cava (SVC) syndrome is an uncommon entity that affects approximately 15,000 Americans per year. Symptoms result from near or complete obstruction of the SVC and include facial and upper-extremity edema, chest pain, cough, dyspnea, dysphagia, proptosis, cyanosis, and headache. The severity of these symptoms relies upon the degree of SVC compression and the location of the obstruct...

1) How are SVC defined in these measurements? As stated in the manuscript, the presence of SVC was “detected” using the CPI, which defined the physical boundaries of SVC encountered by the C-130. Because the CPI was operational on every SVC flight, this optimized the definition of physical boundaries of SVC encountered by the WB-57F. Also, as explained in the manuscript, quantitative 2D-S measu...

A 49-year-old male was referred for catheter ablation for paroxysmal atrial fibrillation (PAF). PAF had recurred after each of 2 prior left atrial ablation procedures. He had a structurally normal heart with a left atrial diameter of 43 mm. The patient presented to the electrophysiology laboratory in AF with an average AF cycle length (CL) of 150 ms and reconnected pulmonary veins. After electr...

This paper describes the fuzzy boundaries between support verb constructions (SVC) with ter “have” and dar “give” and causative operator verb (VopC) constructions involving these same verbs, in Brazilian Portuguese (BP), which form a complex set of relations: (i) both verbs are the support verb of the same noun (SVC); (ii) dar is the standard (active-like) SVC while ter is a converse (passive-l...
