A randomized comparison of modified subcutaneous "Z"-stitch versus manual compression to achieve hemostasis after large caliber femoral venous sheath removal.

Objectives: To compare subcutaneous "Z"-stitch versus manual compression in attaining hemostasis after large bore femoral venous access, and to assess its impact on venous patency.

Background: Structural interventions increasingly require large caliber venous access, for which convenient, safe, and effective method of postprocedural hemostasis is needed. "Z"-stitch has been introduced for this purpose in some centers but systematic data on its performance is limited.

The coexistence of acute aortic dissection with autosomal dominant polycystic kidney disease--description of two hypertensive patients.

Background: Acute aortic dissection is a rare but potentially lethal disease characterized by high early mortality when left untreated. However, survival may be significantly improved by the timely institution of appropriate medical and/or surgical therapy. Autosomal dominant polycystic kidney disease (ADPKD) is one of the most common hereditary disorders, accounting for 8-10% of the cases of end-stage renal disease.
