Renal vein injury complicating removal of intravenous leiomyoma

Intravascular Leiomyomatosis with Intracardiac Extension

Intravenous leiomyomatosis (IVL) is a rare nonmalignant tumor defined as a benign smooth muscle cell neoplasia in the veins. Patients with IVL may present with symptoms of a uterine leiomyoma such as pelvic pain and vaginal bleeding, or cardiorespiratory symptoms, including dyspnea and leg swelling. We report the case of a 65-year-old otherwise healthy Caucasian woman. Past medical history consisted of hysterectomy and left salpingo-oophorectomy 15 years before for multiple uterine fibromyomas associated with leiomyoma of vascular origin. A thoracoabdominal computed tomography (CT) scan confirmed the presence of a mass, measuring 76 × 37 × 44 mm, arising from the inferior vena cava (IVC) at the level of the left renal vein extending all the way into the right atrium and right ventricle. At laparotomy, a tumoral mass was excised from the left broad ligament up to the left renal vein and from the IVC up to its retrohepatic tract. Sternotomy was performed and cardiopulmonary bypass (CPB) was established among ascending aorta, upper vena cava, and right common femoral vein. After atriotomy, a voluminous and firm mass was excised from the right atrium, down to the level of the IVC. CPB was maintained for 80 min. Perioperative transfusion included two plasma and two red blood cells units. No adjuvant treatment was administered. Follow-up with annual CT scans was performed. Patient had no signs of recurrence after 3 years.

Intravenous leiomyomatosis with intracardiac extension - a review of diagnosis and management with an illustrative case

Intravenous leiomyomatosis with intracardiac extension is an uncommon pathologic progression of uterine leiomyomata. It is a histologically benign condition, however due to interfence with right sided cardiac function patients may present with marked cardiovascular compromise and present a diagnostic dilemma to clinicians who are unfamiliar with this condition. Given the rarity of this condition, experience in individual institutions is usually limited to a few cases. We present an illustrative case and provide a review of the clinical presentation, preoperative assessment, operative approach, pathology and postoperative issues. The importance of a multidisciplinary approach to diagnosis and management is highlighted. Operative management aims to completely resect all tumour in the safest manner for the patient, most commonly via single or two stage operation. Where complete resection is achieved, recurrence appears to be a rare event.

Infrarenal transcaval extraction of intracardiac leiomyomatosis

Intravascular leiomyomatosis is a rare, histologically benign disease, and can spread through the venous system to the right cavities of the heart. We report the case of a 39-year-old woman who presented with intravenous leiomyomatosis with extension to the right ventricle, causing heart failure. She underwent surgery successfully, undergoing a total resection of this tumor through the infrarenal cava and the hysterectomy in one surgical stage. Surgical technique considerations are discussed and the literature is reviewed.

Pulmonary artery extension of uterine leiomyoma

Intravenous leiomyomatosis is a rare tumor arising either from a uterine leiomyoma or from uterine vessel walls with extension into venous channels. Although intravenous leiomyomatosis is considered histologically "benign," intrusion to the cardiac chambers is almost malignant given its possibility for destruction of heart valves, extending into the pulmonary vasculature, and embolizing. We report a patient with an intravenous leiomyomatosis progressing through the left iliac vein, along the entire vena cava up to the right cardiac chambers and branches of pulmonary artery (PA), and review the literature on this subject.

The classification and surgical strategy of intracardiac leiomyomatosis

BACKGROUND

There is a great deal of heterogeneity in the surgical strategy to treat intracardiac leiomyomatosis (ICL), leading to a need to create a theoretical tool to clarify this situation.

METHODS

The data of 14 cases of ICL surgically treated in Anzhen Hospital from February 1995 to February 2009 were retrospectively reviewed. A system for classifying ICL was proposed based on four features of the lesion: size of intracardiac component; extent of inferior vena cava (IVC) involvement; venous pathway from uterus to IVC; and laterality of the lesion in the pelvis. The 14 cases of ICL were treated through multiple surgical strategies.

RESULTS

There were no operative deaths. The follow-up was 73.1 +/- 59.2 months and one patient died from recurrence due to incomplete excision 5 months after the primary procedure. The 5-year survival rate calculated through Kaplan-Meier survival curve was 93.16 +/- 4.98%. Of the surviving patients, 13 had ICL, 10 were in the New York Heart Association (NYHA) class I, and three were in NYHA class II.

CONCLUSION

The surgical treatment of ICL can obtain a good mid- to long-term survival rate and satisfactory heart function, and the proposed classification system for ICL may be helpful to guide the selection of the surgical strategy for ICL, and may serve as the future basis for standardising the reporting of ICL management.

Intravenous leiomyomatosis extending into the right ventricle after subtotal hysterectomy

A case of intravenous leiomyomatosis with extension into the right ventricle is described. A tumor in the inferior vena cava was detected three years after a subtotal hysterectomy had been performed for a myomatous uterus but was misdiagnosed as a thrombus. The tumor enlarged and intruded into the right ventricle for which she underwent surgery. The correct diagnosis was made during the surgery, therefore a two-stage resection was planned. Surgical resection is the best treatment for intracardiac extension of intravenous leiomyoma. We recommend iliac venotomy to remove the ilio-caval portion of the tumor in both stages of operations.
