Endovascular IVC Reconstruction in an 18 Year Old Patient with Subtotal IVC Atresia.

ABSTRACT:

Introduction

Inferior vena cava (IVC) atresia is an uncommon venous anomaly that is an under recognised cause of unprovoked acute deep venous thrombosis (DVT) in young adults. The purpose of this case report is to highlight endovascular IVC reconstruction as a feasible treatment option, particularly in challenging cases when other therapeutic modalities have failed.

Report

This is the report of an 18 year old patient with near complete IVC atresia and a longstanding history of exertional nausea of unknown aetiology, who presented with extensive acute DVT. He was treated successfully by endovascular IVC reconstruction after failing initial anticoagulation and thrombolysis. Symptom resolution and venous patency were maintained at 2.5 year follow up.

Discussion

IVC atresia is an important aetiology to consider in a young patient presenting with unprovoked DVT. Endovascular stenting can restore venous patency and is feasible even when there is near complete IVC atresia. This case was uniquely challenging in the length of atretic IVC that was reconstructed and also highlights an atypical clinical presentation of IVC atresia.

Project description:ImportanceSignificant nasal septal deviation may require complex reconstruction to achieve complete correction. Subtotal septal reconstruction is a method for addressing deviations in the L-strut.ObjectivesTo review the long-term outcomes of subtotal septal reconstruction and provide objective evidence of functional and aesthetic improvement.Design, setting, and participantsThis medical record review obtained data on 144 patients who underwent subtotal septal reconstruction from September 1, 2008, to September 1, 2013. Data analysis was performed from September 1, 2013, to September 1, 2014.Main outcomes and measuresFunctional outcomes were measured using the Nasal Obstruction Symptom Evaluation (NOSE) questionnaire, and objective aesthetic outcomes were measured using 3-dimensional (3-D) stereophotogrammetry. Follow-up times were classified as time point 1 (TP1; preoperative), time point 2 (TP2; early postoperative), and time point 3 (TP3; final postoperative).ResultsOf the 144 patients who underwent subtotal septal reconstruction, 104 (72.2%) were female; the mean (SD) age was 37.3 (13.7) years; 57 underwent primary septorhinoplasty; and 87 (60.5%) underwent revision septorhinoplasty. The NOSE scores improved in all 5 categories of nasal obstruction, with mean (SD) survey completion at 270 (260.1) days. Aesthetic results were measured with 3-D imaging after a mean (SD) follow-up of 613.5 (434.4) days postoperatively. No statistically significant loss was found in mean (SD) nasal length over time (TP2 to TP 3, -0.16 [1.36] mm; 95% CI, -0.54 to 0.22 mm; P?=?.41) or between mean (SD) postoperative loss of projection (TP2 and TP3, -0.19 [0.92] mm, 95% CI, -0.45 to 0.07 mm; P?=?.17). An increase in mean (SD) rotation (nasolabial angle) generated with septorhinoplasty (4.24° [11.08°]; 95% CI, 1.14°-7.34°; P?=?.01) and a mean (SD) decrease in rotation detected during postoperative healing (-2.63° [6.96°]; 95% CI, -4.63° to -0.63°; P?=?.01) were found. Although measurement of symmetry was improved in the early postoperative period (TP1 to TP2, -0.16 [1.26] mm; 95% CI, -0.52 to 0.20 mm; P?=?.40), this finding did not become statistically significant until the final measurement (TP1 to TP3, -0.43 [1.07] mm; 95% CI, -0.73 to -0.13 mm; P?=?.007; TP2 to TP3, -0.28 [0.87] mm; 95% CI, -0.53 to -0.03 mm; P?=?.03). A mean (SD) decrease in columellar show was achieved with surgery (-0.66 [1.37] mm; 95% CI, -1.05 to -0.27 mm; P?=?.001). No statistically significant change was found in the alar-columellar association from TP2 to TP3 in this patient population, confirming no unwanted alar or columellar retraction over time (0.10 [0.61] mm; 95% CI, -0.07 to 0.27 mm; P?=?.25). A total of 114 patients (79.2%) required costal cartilage harvest for adequate reconstruction.Conclusions and relevanceSubtotal septal reconstruction yields improved functional and aesthetic outcomes and has the potential to be a useful tool for the rhinoplasty surgeon in the treatment of severe septal deviation.Level of evidence4.
