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 evaluate the therapeutic efficacy of a new liquid embolic material, Embol, in embolization of the renal artery. Materials and Methods: Embol is a new embolic material obtained by partial hydrolysis of polyvinyl acetate mixed in absolute ethanol and Iopromide 370 and manufactured by Schering Korea, Kyonggido, Korea. Six patients who underwent embolization of the renal artery using Embol were evaluated. Four were male and two were female and their ages ranged from 11 to 70 (mean, 53) years. Clinical and radiologic diagnoses referred for renal artery embolization were renal cell carcinoma (n = 3), renal angiomyolipoma (n = 2) and pseudoaneurysm of the renal artery (n = 1). After selective renal angiography, Embol was injected through various catheters, either with or without a balloon occlusion catheter. Changes in symptoms and blood chemistry which may have been related to renal artery embolization with Embol were analyzed. Results: The six patients showed immediate total occlusion of their renal vascular lesions. One of the three in whom renal cell carcinoma was embolized with Embol underwent radical nephrectomy, and the specimen thus obtained revealed 40% tumor necrosis. In the two patients with angiomyolipomas, the tumors decreased in size and abdominal pain subsided. Bleeding from pseudoaneurysm of the renal artery was successfully controlled. Four patients showed symptoms of post-embolization syndrome, and one of these also showed increased levels of blood urea nitrogen and creatinine. One patient experienced transient hypertension. Conclusion: Embol is easy to use, its radiopacity is adequate and it is a safe and effective embolic material which provides immediate and total occlusion of renal vascular lesions.

연구배경 : 대량 객혈은 내과적 혹은 외과적 치료로도 사망율이 매우 높은 임상증상이다. 대량 객혈은 높은 기관지 동맥 혹은 비기관지성 전신동맥에서 출혈된다고 알려져 있으므로, 최근 상기 혈관들을 색전시키는 것이 치료방법으로 되고 있으나 초기 색전후 일부에서 객혈이 재발되는 것이 문제로 되어 있다. 이에 저자들은 대량출혈환자에서 동맥색전을 하여 즉각적인 지혈정도를 알아보고, 즉시 지혈된 후 객혈이 재발되는 환자들의 임상소견 및 초기 동맥촬영소견을 조사하여 보았다. 방법 : 1988년 1월부터 1991년 7월까지 전부 21명의 환자에서 대량 객혈로 동맥색전술을 시행하였다. 환자 모두에서 대퇴통맥으로 경피하 삽관술을 하여 기관지동맥외에도 비기관지 전신동맥에 혈관촬영을 시행한 후, 병변부위의 혈관에 gelfoam pieces로 색전을 실시하였다. 이후 환자들을 추적관찰하면서 동맥색전술의 효과를 평가하였다. 결과 : 처음 동맥색전후 21명의 전환자에서 즉시 지혈은 성공하였다. 9명의 환자에서 출혈이 재발되었으며, 12예의 환자들에서는 객혈의 재발은 없었다. 합병증으로는 발열, 흉통, 기침, 배뇨 장애, 장마비, 하지마비 및 비장경색증등이 있었으며, 9명의 환자에서는 별 증상을 호소하지 않았다. 출혈이 재발된 환자중, 2명은 대량객혈로 사망하였고, 2명은 폐절제술을 시행받았으며, 4명은 매번 객혈이 재발시마다 반복적인 동맥색전술 혹은 내과적 보존치료를 받고 있다. 결론 : 재출혈의 가능성이 있기는 하지만, 동맥색전술은 대량 객혈환자에서 출혈을 비교적 빠르고 안전하게 멈출 수 있는 치료법이다. 또 수술적 치료가 불가능한 폐질환 환자에서 객혈이 재발시마다, 반복 시행하는 동맥색전술은 일단 급한 출혈을 막고 생명을 연장시키는 데에 도움을 주리라 사료된다.

Purpose: This study was conducted to evaluate the effectiveness of the treatment strategy of transcatheter arterial embolization after pelvic CT angiography (CTA) in cases of traumatic pelvic hemorrhage. Methods: This is a retrospective analysis of pelvic hemorrhage patients who underwent transcatheter arterial embolization after pelvic CTA at our regional emergency center during a 31-month period. We reviewed the medical records and imagings of all these patients. Results: Transcatheter arterial embolization was performed in 17 patients (M:F=7:10, mean age=53.9) who underwent pelvic CTA for the evaluation of traumatic pelvic hemorrhage. Arterial bleeding was demonstrated on pelvic CTA in all patients, and the combined injury was also noted in 13 patients. The admission-to-CTA time was $84.53{\pm}66.92$ minutes, and the CTA-to-embolization time was $147.65{\pm}99.97$ minutes. Extravasation of contrast media or pseudoaneurysm was demonstrated on conventional angiography in all patients. Unilateral iliac artery embolization was performed in 8 patients, and bilateral iliac artery embolization was performed in 9 patients. Additional embolizations other than in the iliac arteries were performed in 7 patients. Initial hemostasis was achieved in 16 patients. One patient died of ongoing pelvic bleeding. Rebleeding occurred in only one patient and hemostasis was achieved with the second embolization. Another patient died of intracranial and facial bleeding in spite of pelvic hemostasis. The overall mortality was 11.8%, and there was no significant adverse effects in the other patients. Conclusion: Transcatheter arterial embolization after pelvic CTA is an effective treatment strategy in the management of traumatic pelvic hemorrhage patients.

Dissecting aneurysms frequently involve the vertebral arteries and their branches, but those involving the posterior inferior cerebellar artery [PICA] and not vertebral artery at all are extremely rare. We present a case of an isolated dissecting aneurysm of the PICA without involvement of vertebral artery. A 54-year-old man presented with dizziness and headache. MR imaging of the brain showed a cerebellar infarction of the left PICA territory. MR angiographic and cerebral angiographic studies revealed a dissecting fusiform aneurysm involving the left proximal PICA. Subsequently, the patient underwent GDC embolization. A postembolization angiogram demonstrated complete obliteration of the aneurysm. In this report, the treatment modalities for this rare condition is described with review of the literature.

We present a patient who developed recurrent angina after coronary artery bypass grafting (CABG). Myocardial single-photon emission computed tomography (SPECT) demonstrated deterioration in the myocardial perfusion, and coronary angiography revealed an overgrown side branch of the grafted left internal thoracic artery (ITA); otherwise, there were no significant changes compared with previous imaging studies obtained after the CABG. After percutaneous embolization of the grafted left ITA side branch, the angina was resolved and myocardial SPECT showed improved perfusion.

Knowledge of the venous anatomy is essential for appropriately treating dural arteriovenous fistulas (AVFs). It is challenging to determine the overall venous structure despite performing selective angiography for dural AVFs with feeder from multiple selected arteries. This is because only a part of the veins can be observed through the shunt in the selected artery. Therefore, after performing selective angiography of all vessels to understand the approximate venous anatomy, the venous anatomy can be easily understood by closely examining the source image of computed tomographic angiography or magnetic resonance angiography. Through this, it is possible to specify the vein that is to be blocked (target embolization), thereby avoiding extensive blocking of the vein and avoiding various complications. In the case of dural AVF with feeder from single selected artery, if the multiplanar reconstruction image of the three-dimensional rotational computed tomography obtained by performing angiography is analyzed thoroughly, a shunted pouch can be identified. If embolization is performed by targeting this area, unnecessary sinus total packing can be avoided.

Hyperplastic anterior choroidal artery (AchA) is an extremely rare congenital vascular variant that can be mistaken for other cerebral arteries. This case report presents a 38-year-old man who presented with a severe sudden-onset headache and was diagnosed with a ruptured aneurysm originating from a hyperplastic AchA. The aneurysm was successfully treated with coil embolization, but recurrence was detected after eight months, leading to additional surgical intervention. The discussion highlights the classification of hyperplastic AchA and emphasizes the importance of recognizing this anatomical variant to avoid complications during treatment. This case report underscores the need for awareness and understanding of hyperplastic AchA in the management of cerebral aneurysms.
