“…Regarding the cuff suture technique, these results are in agreement with those reported by Hung et al [8], who did not observed any significant difference in immediate and late patency between the simple interrupted suture and cuff suture. Although there was some degree of endothelial proliferation in that technique, it did not affect the patency rate even though this pathological finding would be expected if even a trivial endothelial injury occurs.…”

“…Moscona and Owen [14] and Chen et al [3] reported that a simple continuous suture technique could save 50% of the anastomotic time in 0-8 mm diameter arteries in an end-to-end anastomosis and vein graft interposition, respectively, when compared with the simple interrupted technique. Regarding the other two suture techniques, Lauritzen and Bagge [11] and Hung et al [8] reported respectively, that the time needed to perform an end-to-end anastomosis using sleeve and cuff suture technique was significantly shorter than the interrupted suture technique, which is in accordance with the current results.…”

“…Chen et al [3] also reported that a lower percentage of rat femoral arteries anastomosed using the continuous suture technique showed blood leakage compared with the case treated using the simple interrupted suture. Lauritzen [10] and Hung et al [8] observed that the simple interrupted suture showed considerable leakage compared with the sleeve and cuff suture in anastomosed rat vessels, respectively.…”

“…The present study showed that the cuff suture technique had a lower frequency of pathological changes. Hung et al [8] also reported only slight changes between the two overlapping vessels in the cuff suture. As with the continuous and sleeve sutures, the cuff suture produced minimal stenosis.…”

This study examined the clinical and pathological features after a microvascular anastomosis of a rat femoral artery using four different suture techniques. Sixty Sprage-Dawely rats were divided randomly into 4 groups. Fifteen bisected arteries (one from each animal) in Group I, II, III and IV were sutured with the simple interrupted suture, continuous suture, sleeve suture and cuff suture, respectively. The anastomosis times in Group I, II, III and IV were 28.67, 14.67, 15.47 and 15.93 min, respectively. Immediate bleeding that stopped without intervention (grade I) was observed in 67%, 73% and 60% of the anastomosed vessels in Groups II, III and IV, respectively, while 60% of the vessels in Group I showed light bleeding that was inhibited by gentile pressure (grade II). All vessels examined appeared to be patent at 5 and 15 min after the anastomosis. On the 7th day postoperatively, the vessels of Group I showed the highest patency rate (93%) compared with Groups II (67%), III (73%) and IV (87%). Moreover, there were more pronounced pathological changes in Group I than in the other groups. These changes included endothelial loss, endothelial proliferation, degeneration and necrosis of the tunica media. Suture materials surrounded by an inflammatory reaction were also observed. In conclusion, the simple interrupted suture is preferable for microvascular anastomosis due to its highest patency rate. The other techniques investigated can be good alternatives because of their short anastomotic time and moderate pathological changes.

A new invention, i.e., a biodegradable, thermosensitive hybrid gel composite in the form of a thin sheet, was used as an implant inside the rat and guinea pig to test its tissue reactions, degradation, and function as a bridging agent. Tissue tractions in subcutaneous tissue, in muscle, around a peripheral nerve, and around an artery were mild. Degradation made rapid progress, starting on the third day and completed in 2-3 weeks. The hybrid gel, when wrapped around the cut ends of a peripheral nerve or an artery, functioned well as a bridging tube. In the case of the cut nerve, regenerating fascicles crept through the tube which protected them from fibrosis. In the case of the cut artery, patency of flow was maintained, and arterial wall healing was complete in 2-3 weeks. The hybrid gel composite contracted at body temperature, thus holding well to body tissues. Its biodegradable and inert nature offers the potential for future use as a tissue wrap and bridging agent.

Classification and comparison of five techniques of end‐to‐end microarterial anastomoses in rats: A new proposed technique

1995

We propose a new classification of five main techniques for microarterial anastomoses: Interrupted, autogenous cuff, continuous, sleeve and partial sleeve. The last method was developed by the authors. A study was performed on 48 albino rats and comprised 20 anastomoses of each type (for a total of 100), performed on femoral and carotid arteries of average size 0.83 mm. These were compared with respect to patency, anastomosis time, leak, bleeding time, number of sutures (bites), microangiography, histopathology and scanning electron microscopy. The overall patency was 88%, and that of the partial sleeve technique was 100%, associated with 30% incidence of aneurysms. Clinical, histopathological and scanning electron microscopy findings showed better results for techniques with predominantly extraluminal sutures (sleeve and partial sleeve), which was particularly relevant in our situation, in which a larger sized needle (150 microns) had to be used. An overall aneurysm incidence of 17% was noted.
