Aberrant Ovarian Collateral Originating from External Iliac Artery During Uterine Artery Embolization

We report a case of a 35-year-old woman who underwent uterine artery embolization (UAE) for symptomatic multiple uterine fibroids with collateral aberrant right ovarian artery that originated from the right external iliac artery. We believe that this is the first reported case in the literature of this collateral uterine flow by the right ovarian artery originated from the right external iliac artery. We briefly present the details of the case and review the literature on variations of ovarian artery origin that might be encountered during UAE.     

Development of a Hypertrophic Ovarian Artery After Uterine Artery Embolization with Polyvinyl Alcohol Particles

Uterine artery embolization (UAE) for the treatment of symptomatic leiomyomata has shown excellent short-term clinical efficacy and minimal complications, yet recurrences after successful treatments at mid- and long-term follow-up have been reported. Exact etiologies for such recurrences have not been fully understood. We present a case of symptom recurrence with the development of a hypertrophic ovarian artery after successful UAE with polyvinyl alcohol particles, successfully treated with ovarian and repeat UAEs.     

Ovarian Artery: Angiographic Appearance,Embolization and Relevance to Uterine Fibroid Embolization

Purpose: To describe the angiographic appearance of the ovarian artery and its main variations that may be relevant to uterine fibroid embolization. Methods: The flush aortograms of 294 women who had been treated by uterine artery embolization for fibroids were reviewed. Significant arterial supply to the fibroid, and the origin and diameter of identified ovarian arteries were recorded. In patients with additional embolization of the ovarian artery, the follow-up evaluation also included hormonal levels and Doppler imaging of the ovaries. Results: A total of 75 ovarian arteries were identified in 59 women (bilaterally in 16 women and unilaterally in 43 women). All ovarian arteries originated from the aorta below the level of the renal arteries with a characteristic tortuous course. Fifteen women had at least one enlarged ovarian artery supplying the fibroids. Fourteen women (14/15, 93%) presented at least one of the following factors: prior pelvic surgery, tubo-ovarian pathology or large fundal fibroids. Conclusion: We advocate the use of flush aortography in women with prior tubo-ovarian pathology or surgery or in cases of large fundal fibroids. In the case of an ovarian artery supply to the fibroids, superselective catheterization and embolization of the ovarian artery should be considered.     

Endovascular Treatment of Aneurysm of Splenic Artery Arising from Splenomesentric Trunk Using Stent Graft

We report a rare case of aneurysm of splenic artery arising anomalously from the superior mesenteric artery (SMA). The aneurysm was treated successfully by coil embolization of the splenic artery distal to aneurysm and then deploying a stent graft in the SMA. A combination of stent graft and coil embolization for the treatment of aberrant splenic artery aneurysm has been reported only once. We describe the imaging findings and the endovascular procedure in this patient.

Pregnancy-unrelated spontaneous rupture of a right ovarian artery aneurysm

Spontaneous rupture of an ovarian artery aneurysm is extremely rare. It can lead to retroperitoneal hemorrhage that is often life-threatening. We report a case of pregnancy-unrelated spontaneous rupture of a right ovarian artery aneurysm in a multiparous woman. A 29-year-old woman, gravida 3, para 3, whose latest pregnancy involved uneventful gestation and delivery 2 years previously, was admitted for right flank pain. The urine test result for pregnancy was negative. Computed tomography revealed a large retroperitoneal hematoma and right ovarian artery aneurysm with contrast extravasation. After selective angiography, embolization of the right ovarian artery was successfully achieved using microcoils. Diagnostic angiography with subsequent transcatheter arterial embolization is an effective and less invasive technique for the management of ovarian artery aneurysm.

Treatment of Uterine Artery Vasospasm with Transdermal Nitroglycerin Ointment During Uterine Artery Embolization

Uterine artery vasospasm can complicate uterine artery embolization (UAE) by prolonging procedure times or even causing treatment failure. Embolization must be delayed until the spasm improves and adequate antegrade flow in the vessel is restored. Vasospasm can also produce a “false endpoint” to the procedure, where stasis of flow in the vessel is falsely attributed to successful embolization but is actually the result of vasospasm, leading to undertreatment or treatment failure. Traditional treatments for uterine artery vasospasm have included transcatheter intra-arterial vasodilators and catheter withdrawal from the vessel, both of which can yield mixed results. We report a case of uterine artery vasospasm during UAE successfully treated with transdermal nitroglycerine ointment. Case Report

Patient Presentation and Management of Labial Ulceration Following Uterine Artery Embolization

Uterine artery embolization is a safe and effective procedure for the treatment of symptomatic uterine fibroids. Nontarget embolization of adjacent internal iliac artery branches is a reported complication of uterine artery embolization. The following report describes the presentation and management of ulcerations of the labium minora due to nontarget embolization of the internal pudendal artery.     

Pulmonary Artery Access Embolization in Patients with Massive Hemoptysis in Whom Bronchial and/or Nonbronchial Systemic Artery Embolization Is Contraindicated

The objective of this paper is to present an alternative therapeutic approach for the treatment of patients with massive hemoptysis in whom bronchial and/or nonbronchial systemic arterial embolization is not possible. We describe a percutaneous procedure for pulmonary segmental artery embolization. Between May 2000 and July 2006, 27 adult patients with hemoptysis underwent percutaneous treatment at our department; 20 of 27 patients were embolized via bronchial and or nonbronchial systemic arteries and 7 patients were embolized via pulmonary artery. Femoral arterial access for systemic artery catheterization and femoral vein access for pulmonary arterial catheterization were used. Gelfoam particles and coils were used for embolization. In this study, we report on three cases of massive hemoptysis from a systemic arterial source in whom bronchial and/or nonbronchial arteries embolization was not possible. Percutaneous embolization via the pulmonary artery access was successful in all three patients. In conclusion, embolization via pulmonary artery is presented as an alternative approach for the management of hemoptysis in patients in whom bronchial arterial embolization is not possible.     

Bronchial Artery Aneurysm Embolization with NBCA

We present a case of asymptomatic bronchial artery aneurysm that formed a fistula with part of the pulmonary artery (there was no definite fistula with the pulmonary vein). We were able to catheterize the feeding vessel but could not reach the aneurysm. We therefore injected a mixture of N-butyl-2-cyanoacrylate (NBCA; Histoacryl, B. Braun, Melsungen, Germany) and iodized oil (Lipiodol; Guerbet, Aulnay-sous-Bois, France) from the feeding vessel. The fistula, aneurysm, and feeding vessel were almost totally occluded. After embolization, the patient coughed a little; there were no other definite side effects or complications. One and 3 months later, on chest CT, the aneurysm was almost completely occupied with hyperattenuating NBCA-Lipiodol embolization. NBCA is a liquid embolization material whose time to coagulation after injection can be controlled by diluting it with Lipiodol. It is therefore possible to embolize an aneurysm, feeding vessels, and efferent vessels (in our case, it was a fistula) by using an NBCA-Lipiodol mixture of an appropriate concentration, regardless of whether the catheter can reach the aneurysm or not.     

胃十二指肠动脉栓塞在肝癌栓塞化疗中的应用

60例肝癌经导管肝动脉栓塞化疗(THAE)前由于导管无法超选择插管而行经导管胃十二指肠动脉栓塞。其中45例用羊毛钢圈栓塞,44例成功:11例以导丝人为损伤血管内膜(导管不能插入)后10例闭塞,另4例导管导丝均不能插入。由于胃十二指肠动脉闭塞,THAE时避免了碘油抗癌药混悬剂或明胶海绵颗粒进入胃十二指肠动脉。所有胃十二指肠动脉栓塞的病例无直接并发症。因此认为,胃十二指扬动脉栓塞是安全的,对防止肝癌THAE时栓塞剂返流所致的胃十二指肠损伤具有重要意义。
