“…Various studies have shown that end-to-side anastomosis with venous couplers is safe and has success rates comparable to those of end-to-end venous coupler anastomosis 26 . Murugan et al 27 compared end-to-end versus end-to-end anastomosis of venous couplers, with 19 patients in each group. They concluded that end-to-side anastomosis was better with decreased anastomotic time and improved ap survivability.…”

Background: Recently, venous couplers have been routinely employed for free flap surgery. Its use is justified considering the large number of backlog cases as well as for surgeon and patient benefit. However, venous thrombosis remains a worrisome problem in the use of venous couplers. Although the efficacy of venous couplers has been found to be equal to that of hand-sewn anastomosis, comparison of single versus double venous coupler anastomosis has not been reported.Materials & Methods: A prospective randomized study carried between 2020 and 2024 included 154 patients who underwent maxillofacial free flap reconstruction; these patients were divided into two groups based on the number of venous coupler anastomoses performed. (Single MACD, n = 82 vs Double MACD, n = 72). Data were evaluated for demographics, perioperative details, vascular thrombosis, flap complications and flap loss.Results: There were no significant differences regarding comorbidities or ASA status between the two groups. Overall, there was no significant difference regarding the rate of venous thrombosis (1 MACD: 2.44% versus 2 MACD: 2.78%, p > 0.05) or flap loss (1 MACD: 1.22% versus 2 MACD: 1.39%, p > 0.05).Conclusions: As our overall survivability rate was more than 97% in each group, it can be concluded that flap survivability is not dependent on the number of venous coupler anastomoses and that it would be safe to proceed with single venous coupler anastomosis with close flap monitoring. Various other factors, such as improper technique, intimal injury, hematoma and pedicle compression, may play more prominent roles in flap survivability.

“…Venous anastomosis is not a task for novices. The primary rationale for this assertion lies in the inherently thinner nature of vein walls which predisposes the vein edges to inward rolling, thereby introducing the potential for errors in stitch placement (8). The author has also encountered in-stances where limited visibility of the mouse renal vein such as concurrent suture between anterior and posterior walls, anastomosis with the renal vein rotated 180 degrees, or hard to first suture into renal vein due to poor visualization of renal vein orifice resulted in surgical failure.…”

The mouse kidney transplantation model serves as an invaluable tool for exploring various aspects of the transplant process, including acute rejection, cellular and humoral rejection, ischemia-reperfusion injury, and the evaluation of novel therapeutic strategies. However, conducting venous anastomosis in this model poses a significant challenge due to the thin and pliable characteristics of the renal vein, which often obstruct clear visualization of the resected vein's edge. This study proposes the adoption of a two stay suture technique to enhance the visualization of the renal vein's edge, thereby facilitating efficient and successful venous anastomosis. A total of 22 mice served as kidney donors in this study. The conventional anchoring suture technique was employed for venous anastomosis in 11 of these mice, while the remaining 11 underwent the two stay suture technique. The anastomosis duration and completion rates were then compared between these two groups. The conventional anchoring suture technique yielded an average anastomosis time of 29 minutes and a completion rate of 64%. In contrast, the two stay suture technique demonstrated a substantial improvement, with an average anastomosis time of 14 minutes and a completion rate of 100%. The two stay suture technique offers a promising solution to enhance visualization during venous anastomosis in murine kidney transplantation. This technique may particularly benefit novices by enabling them to perform venous anastomosis more easily, swiftly, and successfully.
