“…Additionally, incubation with ANG-(1-7) before the addition of phenylephrine or ANG II did not result in any significant change on HMA basal tone. All the patients had preserved endothelial function, as indicated by a maximum decrease in active tension of approximately 80 % in response to acetylcholine, as previously reported [31].…”

Introduction:Microvascular anastomosis is a crucial procedure in replantation surgeries. Venous insufficiency is one of the most consistent cause of failure or re-exploration in these surgeries necessitating the use of venous grafts.Materials and Methods:We discuss our study of 9 such replantation surgeries executed in calendar year 2013-2014, including a double finger replantation done in the same patient having total amputation of 4 fingers of the same (right) hand, in which an arterial segment was used as a microvascular interposition graft for venous anastomosis. Out of these 9 surgeries, 3 were re-exploration procedures for venous compromise and 6 were successful primary replantations.Results:In all, 8 replants were successful and one failed due to arterial compromise.Discussion:In our experience and extensive review of the previously available literature, we would like to portray the advantages of arterial segments as microvascular grafts in replant surgeries. Specifically, in a crush amputation injury for which the use of a vascular interposition graft is being contemplated. If any other digit is also amputated and is unsuitable for replantation, it can act as a potential donor site to harvest the arterial segment. However, when dealing with single finger amputation, the surgeon must be confident about the single digital arterial anastomosis, before harvesting the second digital artery as a microvascular graft.Conclusion:In our study, we found the use of arterial grafts in microvascular anastomosis of veins advantageous, as arterial segments have better ability to resist spasm due to environmental changes, better pressure tolerance as compared to venous segments, and provide an appropriate calibre match and ease of harvest in the same operative field.

“…These characteristics allow this type of graft to maintain its strength while being less susceptible to ischemia [31]. In addition, in an ex vivo study, the DIEA showed weak responses to vasoconstrictors, such as noradrenaline, phenylephrine, and serotonin, with strong responses to vasodilators, including acetylcholine, substance P, and bradykinin [32], which can be advantageous for creating a physiologically favorable graft.…”

Chronic hand ischemia causes cold intolerance, intractable pain, and digital ulceration. If ischemic symptoms persist despite pharmacologic treatments, surgical interventions should be considered. This retrospective study evaluated long-term results after ulnar and radial reconstruction using an interpositional deep inferior epigastric artery (DIEA) graft combined with periarterial sympathectomy. Patients who underwent this surgery from March 2003 to February 2019 were included. To evaluate variables influencing recurrence after the procedure, patients were divided into recurred and non-recurred groups and compared. Overall, 62 cases involving 47 patients were analyzed, with 16 and 46 cases in the recurred and non-recurred groups, respectively. The median length of DIEA grafts was 8.5 cm. Rates of rheumatic disease and female patients were significantly higher in the recurred group than in the non-recurred group, without significant between-group differences in postoperative complication rates. In the multivariate analysis, underlying rheumatic disease and graft length had significant effects on recurrence. In the Kaplan-Meier analysis, the 5- and 10-year symptom-free rates were 81.3% and 68.0%, respectively, with lower rates for cases with rheumatic disease. Thus, arterial reconstruction using an interpositional DIEA graft provides long-term sustainable vascular supply in chronic hand ischemia patients, especially those without rheumatic disease.
