Stroke volume variation and serum creatinine changes during abdominal aortic aneurysm surgery: a time-integrated analysis.

Background: Patients undergoing abdominal aortic aneurysm (AAA) surgery with suprarenal clamping are at high risk for acute kidney injury (AKI) and major cardiac and cerebrovascular events (MACCE). We aimed to assess whether the stroke volume variation (SVV), a measure of hemodynamic instability, is associated with AKI in hypertensive patients undergoing elective AAA surgery with suprarenal clamping.

Methods: In a cohort of 51 hypertensive patients, we performed serial measurements of SVV (n = 459) and serum creatinine (sCr) (n = 255).

Carotid artery stenting in difficult aortic arch anatomy with or without a new dedicated guiding catheter: preliminary experience.

Objectives: To evaluate carotid artery stenting (CAS) procedures with or without a new dedicated guiding catheter in anatomically challenging aortic arches in our experience.

Methods: We retrospectively reviewed 172 procedures of CAS performed from December 2006 to October 2011 in 159 consecutive patients (100 men, mean age 78 years): 15 patients had type III aortic arch, 13 had a bovine aortic arch, 6 had an acute angle at the origin of the left common carotid artery from the aortic arch, 2 had type III aortic arch with bovine aortic arch, and 1 had a bicarotid trunk with an aberrant right subclavian artery. In this group of difficult anatomy (37 cases), CAS was performed with (13 cases) or without (24 cases) a new dedicated guiding catheter.

Does the type of carotid artery closure influence the management of recurrent carotid artery stenosis? Results of a 6-year prospective comparative study.

Objective: The purpose of the study was to evaluate the results of reoperative surgery and carotid artery stenting (CAS) in cases of recurrent carotid artery stenosis (RCS) and to compare the results of all RCS (reoperative surgery + CAS) with primary carotid endarterectomy (CEA) performed during the study period.

Summary Background Data: Consensus has not yet been established on the best treatment for RCS. Recently CAS has emerged as a potential alternative to carotid endarterectomy.

Open repair versus endovascular treatment for asymptomatic popliteal artery aneurysm: results of a prospective randomized study.

Purpose: The aim of this prospective randomized study was to evaluate the relative risks and advantages of using the Hemobahn graft for popliteal artery aneurysm (PAA) treatment compared with open repair (OR). The primary end point was patency rate; secondary end points were hospital stay and length of surgical procedure.

Methods: The study was a prospective, randomized clinical trial carried out at a single center from January 1999 to December 2003.

Popliteal-to-distal bypass for limb salvage.

A retrospective study was carried out to examine the patency and limb salvage rates of popliteal-to-distal bypass and compare the results of diabetic to those of nondiabetic patients and elective versus emergency procedures. From January 1990 to December 2001, 71 popliteal-to-distal bypasses were performed. Indications for surgery were rest pain, tissue loss, and acute ischemia, including extensive post-traumatic tibial lesions.
