Lymphatic disorders encompass a broad spectrum of diseases involving the lymphatic system, ranging from traumatic lymphatic leaks to lymphatic malformations. Lymphatic disorders can be categorized into traumatic and non-traumatic disorders according to their etiology. These two categories may be further divided into subgroups depending on the anatomical location of the lymphatic pathology and their association with clinical syndromes. Thoracic duct embolization was a milestone in the field of lymphatic intervention that encouraged the application of percutaneous embolization techniques to treat leaks and reflux disorders in the lymphatic system. Additional access routes for embolization, including retrograde thoracic duct and transhepatic lymphatic access, have also been developed. This article comprehensively reviews a variety of options for the treatment of lymphatic disorders, from conservative management to the most recent embolization techniques.

Purpose: Immediate identification of vascular injury requiring embolization in patients with pelvic bone fracture isn't an easy task. There have been many trials finding indicators of embolization for patients with pelvic bone fracture. Although Young and Burgess classification is useful in decision making of treatment, it is reported to have little value as indicator of embolization in major trauma patients. The aim of this study is to find out Young and burgess classification on predicting vessel injury by analzyng pelvic radiograph taken from major trauma patients with pelvic bone fracture. Methods: Among major trauma patients with injury severity scores (ISS) higher than 15 who visited our emergency room from January 2011 to June 2014, 200 patients were found with pelvic bone fracture in trauma series and thus pelvic CT angiography was taken. Setting aside patients with exclusion criteria, 153 patients were enrolled in this study for analysis of Young and Burgess classification. Results: The most common mechanism of injury was lateral compression in both groups. There was no statistical significant difference in Young and Burgess classification (p=0.397). The obturator artery was the most commonly injured artery in both groups. Six patients had more than one site of bleeding. Conclusion: Prediction of transcatheter angiographic embolization using Young and Burgess classification in severe trauma patients is difficult and requires additional studies.

Objective : The aim of this study was to evaluate the efficacy of endovascular therapy as a primary treatment for spinal dural arteriovenous fistula (DAVF). Methods : The authors reviewed 18 patients with spinal DAVFs for whom endovascular therapy was considered as an initial treatment at a single institute between 1993 and 2006. NBCA embolization was considered the primary treatment of choice, with surgery reserved for patients in whom endovascular treatment failed. Results : Surgery was performed as the primary treatment in one patient because the anterior spinal artery originated from the same arterial pedicle as the artery feeding the fistula. Embolization was used as the primary treatment modality in 17 patients. with an initial success rate of 82.4%. Two patients with incomplete embolization had to undergo surgery. One patient underwent multiple embolizations, which failed to completely occlude the fistula but relieved the patient's symptoms. Spinal DAVF recurred in two patients (one collateral development and one recanalization) during the follow-up period. The collateral development was obliterated by repeated embolization, but the patient with recanalization refused further treatment. The overall clinical status improved in 15 patients (83.3%) during the follow-up period. Conclusion : Endovascular therapy can be successfully used as a primary treatment for the majority of patients with spinal DAVFs. Although it is difficult to perform in some patients, endovascular embolization should be the primary treatment of choice for spinal DAVF.

The cerebellar hemangioblastoma (CHB) has an abundant blood supply and deep anatomical location. Complete surgical resection is generally very difficult. This study investigated the safety and effectiveness of preoperative embolization followed by surgical resection of CHB in a large cohort of patients. A database of 125 CHB patients with surgical resection in Beijing Tiantan Hospital between July 2006 and July 2012 was reviewed. Of those, 46 cases (experimental group) received preoperative embolization, 79 cases (control group) underwent surgery without embolization. Patient demographics, tumor size, duration of surgery, blood loss, blood transfusion, complications and follow-up results were collected and analyzed retrospectively. In the experimental group, the Kamofsky score (KS) was 80-100 in 40 cases (86.9%), 40-70 in 4 cases (8.7%), and below 40 in 2 cases (4.3%). Among 31 cases with follow-up, KS was 80-100 in 27 cases (87.1%), 40-70 in 2 cases (6.5%), and 0 in 2 cases (6.5%). In control group, KS was 80 -100 in 65 cases (82.2%), 40-70 in 6 cases (7.6%), 10-30 in 3 cases (3.8%), and 0 in 3 cases (3.8%). Among 53 cases with follow-up, KS was 80-100 in 44 cases (83.0%), 40-70 in 4 cases (7.5%), 10-30 in 1 case (1.9%), and 0 in 4 cases (7.5%). There were statistically significant differences between the experimental and control groups in tumor size, duration of surgery, amount of intraoperative blood loss and transfusion (p<0.01). However, complications (p=0.31) and follow-up results (p=0.76) showed no significant differences between groups. Selective preoperative embolization of those CHB patients with richer blood supply, higher hemorrhage risk, is safe and effective, and is a reliable adjuvant therapy for complete surgical resection of CHB.

Heterotopic ossification (HO) around the hip joint is not uncommon following neurological injury. Often, surgical treatment is performed in patients with restricted motion and/or refractory pain due to grade III or IV HO according to Brooker classification. The major complication that occurs as a result of surgical HO removal is perioperative bleeding due to hyper-vascularization of the lesion. Here, we report a case of preoperative embolization in a 51-year-old male patient presenting with restricted bilateral hip range of motion (ROM) due to HO following a spinal cord injury. In the right hip without preoperative arterial embolization, massive bleeding occurred during surgical removal of HO. Thus, the patient received a transfusion postoperatively due to decreased serum hemoglobin levels. For surgery of the left hip, preoperative embolization of the arteries supplying HO was performed. Surgical treatment was completed without bleeding complications, and the patient recovered without a postoperative transfusion. This case highlights that, while completing surgical removal for ROM improvements, orthopedic surgeons should consider preoperative arterial embolization in patients with hip HO.

Objective: To report the authors' experience in performing thoracic endovascular aortic repair (TEVAR) for zone 2 lesions after traumatic aortic injury (TAI). Materials and Methods: This retrospective review included 10 patients who underwent zone 2 TEVAR after identification of aortic isthmus injury by CT angiography (CTA) upon arrival at the emergency room of a regional trauma center from 2016 to 2019. Patients were classified into two groups: those who underwent left subclavian artery (LSA) embolization concurrently with the main TEVAR procedure, and those in whom LSA embolization was not performed during the main procedure, but was planned as a bailout treatment if type II endoleak was noted on follow-up CTA images. Pre-procedural and procedure-related factors and post-procedure prognosis were compared between the groups. Results: There were no differences in pre-procedural factors, occurrence of endoleaks, and post-procedure prognosis (including mortality) between patients in the two groups. The duration of the procedure was shorter in the non-LSA embolization group (61 minutes vs. 27 minutes, p = 0.012). During follow-up, type II endoleak did not occur in either group. Conclusion: Delaying preventative LSA embolization until stabilization of the patient would be desirable when performing zone 2 TEVAR for TAI, in the absence of endoleak on the completion aortography image taken after complete deployment of the stent graft.

연구배경 : 기관지 동맥색전술은 일시적 혹은 영구적인 지혈효과를 기대할 수 있고, 지혈효과이외에도 수술이 불가능한 환자나 수술이 필요한 환자의 경우에 수술전 환자상태를 호전시키기 위한 목적으로 이응퇴고 있다. 저자들은 대량객혈환자에서 동맥색전술의 효과 및 객혈의 재발율을 알아보고 재발된 환자의 임상적, 방사선학적 특징과 임상경과 및 예후를 조사하여 동맥색전술의 유용성을 평가해보고자 하였다. 그리고 색전술후에 재출혈이 일어나는 원인과 재발을 예측할 수 있는 인자를 알아보고자 하였다. 방법 : 객혈을 주소로 입원한 환자중 1회 100cc이상, 1일 500cc이상의 대량객혈로 동맥색 전술을 시행한 47명의 환자를 대상으로 의무기록과 혈관조영술 사진을 후향적으로 조사하였다. 결과 : 1)대량객혈의 원인질환으로는 폐결핵(35예), 기관지확장증(5예), 국균종(2예), 폐암(2예) 폐동정맥기형(1예)와 원인미상(2예)이 있었다. 2) 기관지 동맥색전술의 지혈성공율은 94%였으며, 추적관찰중 객혈의 재발은 40%였다. 3) 초기 기관지 동맥조영술 소견상 색전대상이 양측성인 경우, 체측부동맥-폐동맥간단락이 있는 경우, 기관지동맥이외의 체측부동맥이 영양동맥으로 관여한 경우와 과도한 신생혈관형성이 있었던 경우 등 이들 모두에서 재출혈군과 비재출혈군 사이에서 유의한 차이를 보이지 않았다. 4) 재색전술을 시행한 경우는 18예(13명)였다. 이들 중 14예(78%)에서 혈관의 재개통이 있었으며, 8예(44%)에서 초기에 색전하지 못하였던 혈관들의 과증식으로 인한 새로운 영양동맥의 형성에 의한 재출혈이 있었다. 5) 동맥색전술의 합병증은 발열, 흉통, 기침, 배뇨장애 등 경미한 합병증이 대부분(27예,87%)이었고, 마비성장폐색, 무기폐, 하반신마비, 비장경색 등 장기합병증이 각각 1예씩으로 13%를 차지하였다. 결론 : 기관지 동맥색전술은 대량객혈시 지혈율이 높고 심각한 합병증의 빈도가 적어 효과적이면서도 비교적 안전하게 시행할 수 있는 치료방법으로 사료된다. 대량객혈시 초기 기관지 동맥조영술 소견으로 색전술후 재발을 예측하기는 어려우며, 재출혈이 있는 경우 대부분의 원인은 이전 색전동맥의 재개통과 새로운 영양동맥의 형성이 관여함을 알 수 있었다.
