vascular complications after percutaneous coronary interventions following Hemostasis with manual compression versus arteriotomy closure devices
Journal of the American College of Cardiology, 2001Co-Authors: George Dangas, Roxana Mehran, Spyros Kokolis, Dmitriy N Feldman, Lowell F Satler, Augusto D Pichard, Kenneth M Kent, Alexandra J Lansky, Gregg W Stone, Martin B LeonAbstract:Abstract OBJECTIVES We evaluated the vascular complications after Hemostasis with arteriotomy closure devices (ACD) versus manual compression after percutaneous coronary interventions (PCI). BACKGROUND Previous clinical studies have indicated that ACD can be used for achievement of Hemostasis and early ambulation after PCI. This study investigated the safety of ACD in achieving Hemostasis after PCI compared with manual compression in a large cohort of consecutive patients. METHODS A total of 5,093 patients were followed after PCI was performed with the transfemoral approach. Univariate and multivariate analysis were used to identify the predictors of vascular complications with ACD (n = 516) or with manual compression (n = 5,892) as a Hemostasis option after sheath removal. RESULTS The use of ACD was associated with a more frequent occurrence of hematoma compared with manual compression (9.3 vs. 5.1%, p 15%) with ACD versus manual compression (5.2% vs. 2.5%, p CONCLUSIONS In this early experience with ACD after PCI, their use was associated with higher vascular complication rates than Hemostasis with manual compression.

Similar rates of pseudoaneurysm and arteriovenous fistulae were noted with either Hemostasis technique. Vascular surgical repair at the access site was required more often with ACD versus manual compression (2.5 vs. 1.5%, p = 0.03).

clinical evaluation of emergency endoscopic Hemostasis with bipolar forceps in non variceal upper gastrointestinal bleeding
Digestive Endoscopy, 2010Co-Authors: Mikinori Kataoka, Takashi Kawai, Kenji Yagi, Chizuko Tachibana, Hiroyuki Tachibana, Hiroko Sugimoto, Yasutaka Hayama, Kei Yamamoto, Masaya Nonaka, Takaya AokiAbstract:: The present study was designed to evaluate the usefulness and safety of bipolar hemostatic forceps, known as a less invasive and highly safe means of thermal coagulation used for Hemostasis in cases of non-variceal upper gastrointestinal bleeding. This technique of bipolar forceps is simple, safe and unlikely to induce complications, and is therefore promising as a new technique of endoscopic Hemostasis. The study involved 39 cases where Hemostasis was attempted with bipolar forceps to deal with non-variceal upper gastrointestinal bleeding, including 28 cases of gastric ulcer, six cases of duodenal ulcer, three cases of bleeding after endoscopic submucosal dissection (ESD), one case of Mallory-Weiss syndrome and one case of postoperative bleeding from the anastomosed area. There were 34 males and five females, with a mean age of 63.6 years. Bipolar forceps were the first-line means of Hemostasis in cases of oozing bleeding (venous bleeding), pulsatile or spurting bleeding (arterial bleeding) and exposed vessels without active bleeding. The primary Hemostasis success rate was 92.3%, and the re-bleeding rate was 0%. In cases where the bleeding site was located along the tangential line or in cases where large respiration-caused motions hampered identification of the bleeding site, Hemostasis by means of coagulation was easily effected by application of electricity while the forceps were kept open and compressed the bleeding area. In addition, there were no complications. This technique of bipolar forceps is simple, safe and unlikely to induce complications, and is therefore promising as a new technique of endoscopic Hemostasis.

a randomized comparison of a new flexible bipolar Hemostasis forceps designed principally for notes versus a conventional surgical laparoscopic bipolar forceps for intra abdominal vessel sealing in a porcine model
Gastrointestinal Endoscopy, 2010Co-Authors: Per-ola Park, Christie Cunningham, Omar J. Vakharia, Gregory J. Bakos, Kurt R. Bally, Gary L. Long, Richard I Rothstein, Maria Bergström, Paul C SwainAbstract:Background Current devices for Hemostasis in flexible endoscopy are inferior to methods used during open or laparoscopic surgery and might be ineffective for natural orifice transluminal endoscopic surgery. Objective To compare new flexible bipolar forceps (FBF), designed principally for natural orifice transluminal endoscopic surgery, with laparoscopic bipolar forceps (LBF) for Hemostasis of intra-abdominal porcine arteries. Setting Surgical laboratories in Europe and the United States. Design and Interventions New FBF for Hemostasis (3.7-mm diameter), featuring electrode isolation, were compared with rigid 5-mm LBF (ERBE BiClamp LAP forceps) at recommended settings. A porcine model of acute Hemostasis was prepared by suturing the uterine horns and cecum to the abdominal wall, exposing uterine arteries, ovarian pedicles, cecal mesenteric bundles, and the inferior mesenteric artery. This allowed access to 10 vessels in each pig by transabdominal laparoscopic devices or a transgastric double-channel gastroscope. Vessels were measured, coagulated at 4 and more points, and transected. Blood pressure was increased to more than 200 mm Hg for 10 minutes by administering phenylephrine. Delayed bleeding was identified. Main Outcome Measurements In 7 pigs, a total of 65 vessels (1.5-6.0 mm) were randomly allocated to FBF (n = 32) or LBF (n = 33). Successful Hemostasis both before and after blood pressure increase was equivalent between the 2 groups (before: 88% FBF vs 88% LBF, not significant [NS]; after: 97% FBF vs 94% LBF, NS). With FBF, the number of seals per vessel was 4.8 vs 4.4 with LBF (NS). The energy used to create FBF seals was 19.8 J vs 38.2 J for LBF ( P Limitations Results from porcine studies may not reflect patient outcomes. Conclusions In a porcine model, transgastric FBF endoscopic Hemostasis was as effective as conventional laparoscopic Hemostasis using LBF across a wide range of vessels.
