In the ca.e of the rea. solution of these two equa.ions, they ca. be combined to g.nera.e a.sing.e equa.ion.

Objective: The g.ea. sa.henous vein (g.V) is commonly used a. a.conduit for g.a.ting.during.Ca.g.surg.ry, a.d open g.V ha.vesting.(OVH), commonly used with long.incision to expose the vein. However, endoscopic vein ha.vesting.(EVH) is a. a.terna.ive a.proa.h, utilizing.specia.ized instruments a.d sma.l incisions to ha.vest the vein. Methods: a.retrospective a.a.ysis wa. conducted on a.cohort of pa.ients who underwent Corona.y a.tery bypa.s g.a.t (Ca.g. requiring.g.ea. sa.henous vein (g.V) ha.vesting.which wa. done by EVH or OVH procedures. Demog.a.hic va.ia.les, including.a.e a.d g.nder, were a.sessed for both g.oups. Intra.pera.ive va.ia.les such a. the number of g.a.ts, ca.diopulmona.y bypa.s time, X cla.p time, a.d type of procedure were a.a.yzed. Postopera.ive va.ia.les, including.infection a.d bleeding.ra.es, were a.so eva.ua.ed. Results: The study included 30 pa.ients ea.h underg.ing.Corona.y a.tery bypa.s g.a.t (Ca.g. with need of g.ea. sa.henous vein ha.vesting.which wa. done by EVH a.d OVH. Demog.a.hic va.ia.les were well-ma.ched between the two g.oups in terms of a.e, while a.sig.ifica.t difference in g.nder distribution wa. observed. Obesity a.d smoking.were more preva.ent in the OVH g.oup, a.d EVH wa. a.socia.ed with a.hig.er mea. number of g.a.ts compa.ed to OVH. Conversion to a. open technique occurred in a.portion of the EVH ca.es, a.d infection ra.es did not sig.ifica.tly differ between the EVH a.d OVH g.oups. However, the incidence of postopera.ive bleeding.wa. sig.ifica.tly hig.er in the EVH g.oup. Conclusion: This study provides va.ua.le insig.ts into the demog.a.hic, intra.pera.ive, a.d postopera.ive va.ia.les a.socia.ed with EVH a.d OVH techniques.
