Intraaortic balloon pump (IABP) is used as temporary mechanical assistance in case of cardiovascular diseases, even if different hemodynamic problems and, thus, clinical complications may happen, such as the decrease of visceral perfusion. A computational fluid dynamic (CFD) study was carried out to investigate the effects of different IABP-induced abdominal occlusions on patient-specific aortic flow. Two possible sizes (25 and 34 cm) and two locations (2 and 3 cm) of the balloon were compared, modeling four abdominal occlusions and numerically reproducing IAB inflation/deflation behavior. The results highlighted that the perfusion in renal, mesenteric, and iliac arteries decreases when the abdominal occlusion increases with balloon inflation. The study illustrates also how the balloon size affects the flow in aorta vessels in both locations, and that the positioning is of little relevance for the 34 cm balloon, whereas it influences the aortic flow very much in case of 25 cm IAB. This analysis demonstrates how the IAB-induced occlusion may vary the abdominal circulation; therefore, the correct size and positioning are emphasized for patient's outcome.

Impact of Antithrombotic Therapy on Thrombotic and Bleeding Complications after Elective Endovascular Repair of Abdominal Aortic Aneurysms.

Department of Surgery, Rijnstate Hospital, Arnhem, The Netherlands.
Purpose: To investigate the influence of antithrombotic therapy on occurrence of thrombotic and bleeding complications after endovascular aneurysm repair (EVAR).
Methods: In this retrospective single-center cohort study, patients who underwent elective endovascular aneurysm repair for abdominal aortic aneurysm were categorized into three antithrombotic groups: single antiplatelet therapy (SAPT), anticoagulants, or dual antiplatelet therapy (DAPT). Outcome measures were the incidence of major adverse cardiovascular events (MACE), prosthetic limb occlusions, and bleeding complications during follow-up.
A Novel Method for Hemorrhage Control During Laparoscopic Distal Pancreatectomy with Splenic Vessel Preservation: Triple Occlusion.

Introduction: Laparoscopic distal pancreatectomy (LDP) has the advantages of reduced blood loss, shorter hospital stays, and a better postoperative quality of life compared with open distal pancreatectomy (ODP). Meanwhile, spleen-preserving laparoscopic distal pancreatectomy is the preferred technique for low-grade malignant and benign tumors located in pancreatic body and tail, since it preserves the immune function of the spleen. The splenic-vessel-preserving (SVP) Kimura technique and splenic vessel resection Warshaw technique are the two primary procedures.

Objective: Low-profile endografts have reported increased rates of limb graft occlusions. The INCRAFT stent graft system is an ultra-low profile endograft for the exclusion of infrarenal abdominal aortic aneurysms. Our aim was to report thromboembolic events (TE) in patients treated with the INCRAFT device and its association with risk factors.
