Case ReportsExpanding refractory rectus sheath hematoma: a therapeutic dilemma.
Rectus sheath hematoma is an uncommon but well-described complication of a tussive paroxysm. It is an accumulation of blood within the sheath of the rectus abdominis secondary to disruption of the epigastric vessels or the rectus muscle and is often misdiagnosed as acute abdomen. Increases in the number of elderly patients and the use of therapeutic anticoagulation may increase the prevalence and severity of rectus sheath hematomas encountered in clinical practice. ⋯ Repeated computed tomography showed two separate expanding rectus sheath hematomas, which were not accompanied by obvious contrast extravasation on angiography. Empiric left inferior epigastric artery embolization resulted in rapid hemodynamic stabilization, and the hematomas shrank gradually. Early empiric transcatheter arterial embolization may be appropriate for patients who are poor surgical candidates and have enlarging hematomas that are refractory to conservative treatment.

Ideal combination of MRI sequences for perianal fistula classification and the evaluation of additional findings for readers with varying levels of experience.
The aim of our study was to assess the contribution of various magnetic resonance imaging (MRI) sequences in determining the type of perianal fistula and in obtaining critical information for surgical decisions, as well as to define the optimal combination of sequences for readers with varying levels of experience. ⋯ For experienced readers, combining FS-CE-T1W-GRE images with either T2W or STIR images collected in both the coronal and axial planes was sufficient to make an assessment before deciding the surgical extent of the procedure.

Ultrasound-guided puncture of the femoral artery for total percutaneous aortic aneurysm repair.
The purpose of this study was to evaluate the outcomes of ultrasound-guided femoral artery access for total percutaneous endovascular repair of abdominal and thoracic aortic aneurysms. ⋯ Ultrasound-guided puncture of the common femoral artery for percutaneous closure of the access site has a high technical success rate and a very low complication rate. The addition of ultrasound guidance decreases the difficulty of the procedure and helps to avoid some of its complications.
