Median Arcuate Ligament Compression in Orthotopic Liver Transplantation: Results from a Single-Center Analysis and a European Survey Study.

ABSTRACT: Median arcuate ligament compression (MALC) potentially causes arterial complications in orthotopic liver transplantation (OLT). Here we aimed to investigate the incidence of MALC and its impact on clinical outcome after OLT. In addition, we performed an international survey among 52 European liver transplant centers to explore local protocols on the management of these patients. Data of 286 consecutive OLT recipients from a prospective database were analyzed retrospectively (05/2010-07/2017). Preoperative computed-tomography images were evaluated. Celiac axis stenosis due to MALC was found in 34 patients (12%). Intrinsic stenosis was present in 16 (6%) patients. Twenty-six patients (77%) with MALC underwent standard arterial revascularization with median arcuate ligament (MAL)-division. Patients treated for MALC had comparable baseline data and no difference was found in early- and long-term outcome compared to the rest of our cohort. Our survey found heterogeneous strategies regarding diagnosis and treatment of MALC. Only 29% of the centers reported the division of MAL in these patients as routine procedure. Even though there is no consensus on diagnosis and management of MALC among European centers, a surgical division of MAL is feasible and safe and should be considered in OLT recipients with MALC.

Project description:OBJECTIVE:Optimal diagnosis and management of median arcuate ligament (MAL) syndrome (MALS) remains unclear in contemporary practice. The advent and evolution of laparoscopic and endovascular techniques has redirected management toward a less invasive therapeutic algorithm. This study examined our contemporary outcomes of patients treated for MALS. METHODS:All patients treated for MALS at Dartmouth-Hitchcock Medical Center from 2000 to 2013 were retrospectively reviewed. Demographics and comorbidities were recorded. Freedom from symptoms and freedom from reintervention were the primary end points. Return to work or school was assessed. Follow-up by clinic visits and telephone allowed quantitative comparisons among the patients. RESULTS:During the study interval, 21 patients (24% male), with a median age of 42 years, were treated for MALS. All patients complained of abdominal pain in the presence of a celiac stenosis, 16 (76%) also reported weight loss at the time of presentation, and 57% had a concomitant psychiatric history. Diagnostic imaging most commonly used included duplex ultrasound (81%), computed tomography angiography (66%), angiography (57%), and magnetic resonance angiography (5%). Fourteen patients (67%) underwent multiple diagnostic studies. All patients underwent initial laparoscopic MAL release. Seven patients (33%) underwent subsequent celiac stent placement in the setting of recurrent or unresolved symptoms with persistent celiac stenosis at a mean interval of 49 days. Two patients required surgical bypass after an endovascular intervention failed. The 6-month freedom from symptoms was 75% and freedom from reintervention was 64%. Eighteen patients (81%) reported early symptom improvement and weight gain, and 66% were able to return to work. CONCLUSIONS:A multidisciplinary treatment approach using initial laparoscopic release and subsequent stent placement and bypass surgery provides symptom improvement in most patients treated for MALS. The potential placebo effect, however, remains uncertain. A significant minority of patients will require reintervention, justifying longitudinal surveillance and prudent patient selection. Patients can anticipate functional recovery, weight gain, and return to work with treatment.
