Purpose: To evaluate safety and cost benefits of the percutaneous technique for treatment of aortic aneurysm, a prospective randomized study was performed that compared the endovascular suture technique with conventional cutdown access and repair.
Materials And Methods: From January 2002 through July 2002, 30 endografts, including 14 Talent stent-grafts (Medtronic, Sunrise, Fla) and 16 Zenith endografts (Cook, Bloomington, Ind) were implanted in 30 patients for endovascular aneurysm treatment. The patients were randomized to either percutaneous technique (group A) or conventional cutdown (group B). Fifty-five femoral arteries were cannulated with large-bore (14F-25F) introducers and were included in the study. Safety and efficiency of both techniques were assessed by recording the complication rates, operation time, discharge, and time to ambulation. Comparison of selected estimated costs included both variable and fixed costs for femoral access and expenses for treatment of complications.
Results: No operative deaths occurred. The complication rates were similar and included 1 arterial thrombosis in each group, 3 lymphoceles in group B, and 1 conversion to cutdown because of bleeding in group A. Mean surgery time (86.7 +/- 27 minutes vs 107.8 +/- 38.5 minutes; P <.05) and time to ambulation (20.1 +/- 4.3 hours vs 33.1 +/- 18.4 hours; P <.001) were significantly shorter in the group treated percutaneously. Because of the cost of the closure device, total cost of the percutaneous technique averaged 99.2 euro; more than cutdown.
Conclusions: The percutaneous technique decreases the invasiveness of endovascular therapy of aortic aneurysm and reduces operative time and time to ambulation. Complications were roughly equivalent in severity. The additional cost for the device appears to justify its use for this form of aneurysm treatment.

Article Synopsis
- Popliteal artery injury is a rare but significant complication of knee arthroscopic surgery, highlighting a need for more research due to a lack of data and guidelines.
- The study analyzed 17,000 procedures and found a 0.059% incidence of popliteal artery injury among 10 patients, detailing the types of surgeries performed and various treatment methods used.
- After an average follow-up of over 43 months, patients showed no reported complications and exhibited positive recovery in joint function and vascular health.

Introduction: ProGlide is a suture-mediated vascular closure device (VCD) indicated for retrograde access closure at the common femoral artery (CFA). However, its off-label use for antegrade and/or superficial femoral artery (SFA) access has become common in many practices. This study evaluated the efficacy and safety of ProGlide for femoral artery access closure in patients undergoing antegrade infrainguinal endovascular procedures.

This case study presents the successful treatment of a 26-year-old male who experienced profuse bleeding from a gunshot wound to his thigh 4 days after the initial injury. The patient underwent surgery performed by a military vascular surgeon, during which previously undetected injuries to the femoral artery and vein were identified. The surgeon conducted a femoral artery alloprosthesis and sutured the damaged femoral vein.

Rupture of abdominal aortic aneurysm (AAA) due to an isolated type II endoleak (TIIEL) is rarely reported, accounting for less than 1% of all TIIELs; typically, rupture associated with TIIEL is accompanied by type I or type III endoleaks. We report a case of ruptured AAA secondary to TIIEL without any other types of endoleaks, occurring late after endovascular abdominal aortic repair (EVAR). A 77-year-old man with a history of EVAR 11 years earlier presented with abdominal pain.

Article Synopsis
- Endovascular procedures like TAVR, TEVAR, and EVAR are becoming more common but still carry risks, especially for older and frail patients.
- This paper discusses two cases where complications arose from large bore access during such procedures and the innovative methods used to manage them.
- The insights gained from these cases provide valuable guidance for clinicians facing similar challenges in future interventions.
