2024年9月4日 · ULPs are small saccular regions of contrast enhancement that protrude from the aortic lumen into the intramural hematoma 3. They communicate widely with the true lumen 1. As with intramural hematomas, they most commonly occur in the descending aorta.

Some studies have shown that the presence of ULP is intramural aortic hematoma (IMH) is associated with a progressive disease course. A 57-year-old female, with a history of severe hypertension presented with interscapular pain with a sudden onset. On physical examination, she had a high blood pressure 220/120.

2008年2月1日 · In this study, an ULP was defined as a focal, well-defined, blood-filled pouch projecting into the thrombosed lumen of the aorta. The development of aortic dissection or aneurysm on follow-up CT examinations was assessed as a complication.

2010年9月14日 · Initial aortic diameter and development of ULP in the PD are both strong predictors of adverse aorta-related events in patients with type B AD with CTFL. Patients with newly developed ULP should be more carefully followed up with close surveillance imaging than those without ULP.

Intramural hematoma (IMH), penetrating atherosclerotic ulcer (PAU), and aortic dissection can occur as isolated processes or can be found in association. All these entities are potentially life threatening, so prompt diagnosis and treatment is of paramount importance.

2014年3月1日 · The purpose was to investigate changes of the affected aorta after endovascular treatment for complicated ulcer-like projection (ULP), including aneurysmal change or rupture of ULP, or both, in patients with type B aortic intramural hematoma (IMH).

2024年3月15日 · The ulcer-like projections (ULP), which are described as a focal, blood-filled pouch protruding into the hematoma of the aortic wall, are regarded as one of the high-risk imaging features of IMH and may cause initial medical treatment failure and death.

ULP was defined as a localized blood-filled pouch protruding into the thrombosed false lumen. In the present study, we included the patients who showed very small collection of contrast material (localized contrast pooling: LCP) within the aortic wall without apparent flow communication.

2022年1月1日 · The observation of intimal defects or ULP may help to predict aorta-related events and assess the necessity of prophylactic stent-grafting. In this study, ULP can arise and cause progressive dilation of false lumen after TEVAR.

ULP is a term representative of the luminal morphology initially observed on angiography and indicates the disruption of intima due to aortic dissection. A: ULP is seen on the aortic arch...
