Unlabelled: We investigated the prevalence of vascular complications after PCI following hemostasis in 190 patients (67% men and 33% women, mean age 64 years) treated with the AngioSeal vascular closure device (St. Jude Medical, Austin, Texas) versus 238 patients (67% men and 33% women, mean age 64 years) treated with the Mynx vascular closure device (AccessClosure, Mountain View, California).
Results: Death, myocardial infarction or stroke occurred in none of the 190 patients (0%) treated with the AngioSeal versus none of 238 patients (0%) treated with the Mynx. Major vascular complications occurred in 4 of 190 patients (2.1%) treated with the AngioSeal versus 5 of 238 patients (2.1%) treated with the Mynx (p not significant). Major vascular complications in patients treated with the AngioSeal included removal of a malfunctioning device (1.1%), hemorrhage requiring intervention (0.5%) and hemorrhage with a loss of > 3g Hgb (0.5%). The major vascular complications in patients treated with the Mynx included retroperitoneal bleeding requiring surgical intervention (0.8%), pseudoaneurysm with surgical repair (0.8%) and hemorrhage with a loss of > 3g Hgb (0.4%). These complications were not significantly different between the two vascular closure devices (p = 0.77). Minor complications included hematoma > 5 cm (0.5%, n = 1) within the AngioSeal group, as well as procedure failure requiring > 30 minutes of manual compression after device deployment, which occurred in 7 out of 190 patients (3.7%) treated with the AngioSeal versus 22 of 238 patients with the Mynx (9.2%) (p = 0.033).
Conclusions: Major vascular complications after PCI following hemostasis with vascular closure devices occurred in 2.1% of 190 patients treated with the AngioSeal vascular closure device versus 2.1% of 238 patients treated with the Mynx vascular closure device (p not significant). The Mynx vascular closure device appears to have a higher rate of device failure.

Reconstruction of Abdominal Defects After Open Abdomen Treatment Using Propeller Flaps of the Superior and Deep Inferior Epigastric Artery System: Report of Two Cases.

Open abdomen treatment (OAT) is associated with significant morbidity and mortality. In cases where primary or delayed fascial closure cannot be achieved, vacuum-assisted wound closure and mesh-mediated fascial traction are indicated, which often result in a planned ventral hernia. If secondary skin closure is not feasible, common treatment of granulated abdominal defects involves split-thickness skin-grafting or healing by secondary intention leading to significant scarring and sometimes mutilating defects.

BACKGROUND Terminal ileum (TI) anastomoses present challenges due to anatomical features and pressure from the ileocecal valve (ICV). The use of negative-pressure wound therapy (NPWT) is commonly used to treat chronic skin ulcers. Its use for temporary abdominal closure following anastomosis is controversial but has shown promise in patients with inflammatory or vascular disease.

Background: Pseudoaneurysm after coarctation of the aorta (CoA) repair is a rare but severe complication. Contributing factors may include infection, hypertension, aortic wall weakness, and turbulent blood flow at the repair site.
Case Presentation: A 35-year-old male presented with recurrent episodes of epistaxis and dizziness was admitted to the emergency department.

Basic Dental Sciences Department, Faculty of Dentistry, Zarqa University, PO Box 2000, Zarqa, 13110, Jordan.
Objective: This study aimed to investigate and compare the histological response of rabbit dental pulp after direct pulp capping with 3 different materials: mineral trioxide aggregate (MTA), nanoparticles of fluorapatite (Nano-FA), and nanoparticles of hydroxyapatite (Nano-HA) after 4 and 6-week time intervals.
Material And Methods: A total of 72 upper and lower incisor teeth from 18 rabbits were randomly categorized into 3 groups)24 incisors from six rabbits each. MTA Group: teeth were capped with MTA.

Department of Cardiology, Turku University Hospital, Turku, Finland.
Background: Vascular and bleeding complications remain a concern after transfemoral transcatheter aortic valve replacement (TAVR). The impact of the sheath type on these complications remains unclear.
Methods: The prospective MARVEL registry study analyzed enrolled 500 patients undergoing large-bore transfemoral procedures and arteriotomy closure with the MANTA vascular closure device from 10 hospitals in Europe and Canada.
