Grabb and Smith's Plastic Surgery. - ref: Comparison of continuous and interrupted suture techniques in microvascular anastomosis. Although the surgeon performing free flap transfer should always aim to decrease ischemia time, it is especially … 5th ed. Microvascular anastomosis is a highly skilled surgical technique that requires the assistance of optical magnification via an operating microscope or loupes to be fully visualised and thus accomplished reasonably well.

An additional histological study was performed to compare their immediate traumatic effects on vessel wall. Always see where the tip of your needle is going – never guess. The sleeve-technique showed the biggest pressure drop (56±16.41 mmHg), however, it was the fastest method. Effect of Microvascular Anastomosis Technique on End Product Outcome in Simulated Training: A Prospective Blinded Randomized Controlled Trial.  |  We performed the patency test immediately after microvascular anastomosis and one week after surgery.  |  Presented at the 6th International Course on Perforator Flaps, Taipei, Taiwan, October 25–27, 2002.

Firstly, the use of a vessel sizer to determine the size of the coupler for any individual case, with the vessel end prepared and passed through the coupling ring. HHS Many techniques were used to reduce clamping time of the recipient vessel. Coupled suturing: A new technique for microvascular anastomosis Huang Cheng‐Da M.D. Our results support the demand for a careful and atraumatic suture technique in microvascular … Because of the traction applied and the limited space and intervals between sutures, the surgeon tends to take an inverting bite from the vessel without seeing the lumen clearly at all times during the anastomosis, which, in my view, is the most critical factor for … Anastomoses should be water-tight with the least number of sutures. Meticulous dissection of the bowel and the suture technique is of great importance to avoid insufficiency. Maximize patency by avoiding constriction or suturing vessel Br J Plast Surg. gical suture technique for microvascular anastomosis, and continues to present the array of non-suture methods currently proposed as alternatives to standard suturing. BACKGROUND:Suturing of microvascular anastomosis is still a time-consuming procedure, despite the fact that different techniques and devices were designed to reduce the operation time and increase the patency rate. We demonstrate a microsurgical suture technique performed without any vascular clamp on a rat model. Coupling technique comprised several key steps. springer. 3. The histologic damages to occluded area were not significantly different in both groups.

Spiral interrupted suturing technique for microvascular anastomosis: a comparative study. Statistical analysis. CONCLUSIONS: The Arista-assisted microvascular anastomosis is an alternative to the conventional suture-only method because it reduces the anastomosis time significantly and does not cause narrowing of the vessel wall.  |  the tissue variable was exclud ed, and only the suturing technique and the sutur e material could be inv estigated. Corresponding Author. The authors innovated heel suturing on the donor vessel prior to arteriotomy (HSDA) technique from the previously … The alternative technique involves placing the sutures in the posterior wall of the vessel, eliminating the necessity of rotating the microsurgical clamp during the anastomosis. Overview; Fingerprint; Abstract. The patients selected for the study were randomly allocated to five groups of different techniques of venous anastomosis, namely Group I (conventional microsuturing), II (fibrin sealant reinforced microsuturing), III (couplers), IV (staplers), V (Laser Assisted Vascular Anastomosis (LAVA)).

A review of vascular anastomosis with mechanical aids and nonsuture techniques. The most recent review of suture techniques in microvascular anastomosis shows that a statement cannot be made to favor either technique’s patency rate and/or ease of performance when comparing end-to-end and end-to-side configurations, mainly because there is no study in humans 6. This section addresses the development of microsurgical suture technique for microvascular anastomosis, and continues to present the array of non-suture methods currently proposed as alternatives to standard suturing. With the conventional techniques of tying knots during microvascular anastomosis or neural suturing, time may be lost due to various reasons. Neil A. Sharkey. Overview; Fingerprint; Abstract. 2.

Sufficient opportunity in routine surgery may not be available for the beginners. While you are suturing, take steps to avoid going through the back wall: Have the tip of your needle pointing horizontally along the surface of the vessel, never pointing down into it.

Clinically, this method may be advantageous in cases where the anastomosis is being performed in a deep wound in which there is no room to turn over the microclamp. This study compared both clinically and pathologically the continuous, sleeve and autogenous arterial cuff suturing techniques with the conventional interrupted technique in the rat femoral artery. Anthony V. Seaber. The time taken for anastomosis (time taken for suturing and applying couplers) and flap ischemic time (from the time of flap division from the donor site till the flap is reperfused … We also assess other endpoints, including ischemic time, patency rate, and clinical features. The following section deals with the authors’ particular technique for microvascular suture in the rat aorta; modifications and their sources will be mentioned.

Chen L, Chiu DT. - total thrombosis rate was 8%, but no significant patency difference was noted between the CST and the interrupted suture technique in any vessel category. Because tangle of threads usually occurs, especially after arteriotomy c, we sometimes wasted time identifying the needle and its thread before making the first suture and tying the knot, especially in deep operative field. - Technique of anastomosis of larger vessels - considerations: - prosthetic grafts - vascular shunts - initial preparation: - … The spiral interrupted suturing technique … Vessels were prepared using 4 % lignocaine and clamped.
