دراسة لحالات إصلاح تضيق برزخ الأبهر باستخدام شريحة الشريان تحت الترقوة الأيسر

Abstract EN

Background & Objective: Coarctation represents 5-8% of congenital heart disease.We present here a study which aimed to assess the results of this malformation correction by using left subclavian artery flap aortoplasty technique(Waldhausen) and compare these results with those of other surgical options.

Material & Method: A retrospective study at Damascus cardiovascular surgery centre in the period between JAN.2003 to MAR.2009 was conducted.39 patients underwent coarctation repair surgery,of which 23 cases were performed according to Waldhausen technique (58,9% of coarctation patients).

Results: their ages ranged between 3 months to 18 years.Trans thoracic echocardiography confirmed the diagnoses in all cases.It showed PDA with a rate reaching 51% and VSD in 23% of cases.A significant drop in gradient was observed postoperatively(more than 75% in most cases).mortality rate was 0%,however,the incidence of recurrent coarctation in neonates remained significant with each method(up to 25%).No postoperative complications were recorded.

Conclusion: this technique has many advantages including less overall dissection,option to retain a PDA ,its simplicity and its efficacy but all cases should to be followed up in the future.
