| Popis: | A novel device for obtaining arterial hemostasis after invasive procedures was tested in 30 patients undergoing diagnostic catheterization (26 patients) or coronary angioplasty (4 patients). The device is deployed through an arterial sheath and forms a positive mechanical seal both inside and outside the defect in the arterial wall. The components are all bioabsorbable. Thirteen patients received a heparin bolus during the catheterization procedure. The activated clotting time recorded in 15 patients just prior to device deployment averaged 264 sec. 29 of 32 attempted device deployments were successful (91%); and the remaining 3 devices pulled completely out as called for by design in the event of incomplete deployment. Twenty-nine patients ultimately achieved successful hemostasis using the device, with the other patient receiving manual hemostasis. Of these 29, hemostasis was immediate and complete in 19 patients. Light digital pressure was required in another 8 patients for less than 5 min. There was minor delayed bleeding requiring supplemental light pressure in several cases. A total of 11 patients required supplemental pressure in addition to the hemostasis device. The use of bolus heparin was significantly (P = 0.05, Fisher's exact test) related to the requirement for supplemental pressure. Three patients developed hematomas, one of which was present prior to device deployment. The other two patients had received bolus heparin. No patient required transfusion or surgical repair. There was no change in the ankle/brachial systolic blood pressure index after device deployment or at late (30-60 day) follow-up. Ultrasound studies revealed no significant pathology relative to the device.(ABSTRACT TRUNCATED AT 250 WORDS) |
