Nonthrombotic iliofemoral venous obstruction, masquerading as deep vein thrombosis, was diagnosed in four patients. In each instance the patient was hospitalized and intravenous heparin therapy was started. Phlebography demonstrated venous outflow obstruction without thrombosis; subsequent CT scanning revealed an obstructing lesion in each case. At surgical exploration, (1) endoaneurysmorrhaphy of a hypogastric artery aneurysm decompressed an obstructed right iliac vein; (2) a primary iliac vein leiomyosarcoma was extirpated; (3) a synovial cyst arising from the right hip joint, which obstructed the femoral vein, was excised; and, (4) a postherniorrhaphy inflammatory mass obstructing the left iliofemoral vein junction was confirmed with biopsy results. Improved diagnostic accuracy with its attendant specific therapy is achieved in suspected cases of iliofemoral vein thrombosis if, in addition to noninvasive venous studies or phlebography, CT scanning of the abdomen and pelvis is performed.

We describe a patient with antiphospholipid antibody syndrome (APS) who died because of relentless inferior vena cava (IVC) tumor thrombosis due to an unsuspected leiomyosarcoma. Laboratory confirmation for APS was provided by functional identification of a lupus anticoagulant and anticardiolipin IgG and anti-beta2-glycoprotein I IgM antibodies. Although sensitive for detecting vascular obstruction, radiocontrast venography and magnetic resonance imaging and angiography detected the IVC thrombosis but failed to distinguish its malignant nature. Concomitant refractory thrombocytopenia prevented further invasive diagnostic and therapeutic maneuvers for progressive, severe IVC thrombosis unresponsive to aggressive treatment of APS. Deep venous thrombosis refractory to anticoagulant and immunomodulatory therapies in a patient with APS may be due to a concomitant underlying malignancy, such as a leiomyosarcoma, causing vascular obstruction.

A complete surgical resection is the only proven therapeutic modality that prolongs the survival in patients with leiomyosarcoma of the inferior vena cava (IVC). Reconstruction of the IVC is not always necessary but is often required to facilitate venous drainage of the kidney for the tumors at the pararenal area of the IVC. Controversy exists in postoperative adjuvant therapy. Recently, we experienced four cases of pararenal leiomyosarcoma of the IVC, of which treatment consisted of a complete resection of the tumor, ringed polytetrafluoroethylene (PTFE) graft interposition, and bilateral renal vein reconstructions in all patients. Postoperative radiation therapy was instituted in 3 of 4 patients. One patient who did not receive the postoperative radiation therapy was treated with adjuvant chemotherapy. The kidneys were preserved in all patients and no deep vein thrombosis (DVT) or venous insufficiency of the lower extremity veins developed. Distant metastasis to the lung was noted in one patient at 18 months after surgery, who was not received the postoperative radiation therapy but chemotherapy. In conclusion, a complete resection of the tumor, IVC reconstruction, and bilateral renal vein reconstruction followed by adjuvant radiation therapy is recommended for the treatment of pararenal leiomyosarcoma of the IVC.

A cystectomy for indications other than transitional cell cancer of the bladder or general bladder cancer is frequently performed in cooperation with other surgical specialties such as general surgery or gynecology. In these cases the urological procedure as well as the oncological and surgical concepts of other specialties have to be combined. We studied our cystectomy patients who had undergone such a combined procedure for a non-urothelial indication concerning perioperative and postoperative complications.A total of 204 cystectomies were performed by the Department of Urology at the University of Hamburg, Germany between 1995 and 2003. Bladder cancer was the indication for cystectomy in 162 patients, but 42 patients had a non-urothelial indication for this procedure. These patients included 12 cases of advanced rectal cancer, 9 cases of advanced cervical cancer, 6 cases of advanced sigmoid cancer, 4 cases of advanced prostate cancer, 1 case of prostate sarcoma, 5 cases of complex vesicointestinal fistulae, 2 cases of urachal cancer, 1 leiomyosarcoma, 1 rhabdomyoma, and 1 rhabdomyosarcoma, respectively. Perioperative and postoperative complications of those patients were compared to patients who underwent cystectomy for transitional cell cancer of the bladder.Those 42 patients who underwent cystectomy for non-urothelial indications included 14 male and 28 female patients. The mean age was 58.2 years with a range of 3-78 years. For urinary diversion 30 ileum conduits, 4 sigma conduits, and 8 ileum neobladders were used. The mean operative time was 6.25 h. The mean blood loss was 2200 ml. An average of four red blood cell concentrates (RBC) had to be given. Postoperative hydronephrosis had to be treated in three (7%) patients unilaterally and in two (5%) patients bilaterally with a temporary nephrostomy. Postoperative urinary leakage lasting more than 30 days was found in two (5%) patients. A deep vein thrombosis as well as an ileus was found in five (12%) patients each, respectively. There was no perioperative mortality in this study. When comparing the complications of those patients with the 162 patients who underwent cystectomy for bladder cancer, the only significant difference ( p=0.033, chi-square test) was a higher ileus rate in the patients with cystectomy for a non-urothelial indication. Complications with cystectomy for non-urothelial indications are in large comparable to those for transitional cell carcinoma of the bladder. The higher ileus rate in non-urothelial patients can be explained by the more radical procedures in this group of patients. Even though the group of patients undergoing cystectomy for indications other than bladder cancer was small in this trial, the procedure is standardized in combination with other specialties. Larger patient numbers and a longer follow-up will lead to more data in this special group of patients.

Leiomyosarcoma of the inferior vena cava (IVC) is a rare lesion with less than 300 cases reported. Optimal management and long-term outcomes are not well described. From August 1984 to June 2004, eight patients with leiomyosarcoma of the IVC were treated at our institution. Clinical and pathologic data, surgical management, and outcomes were assessed. Eight cases were identified (4 males) with a median age of 52 (range 29-66). Presenting symptoms included abdominal pain (n = 5, 63%), lower extremity edema (n = 2, 25%), and palpable mass (n = 2, 25%). Tumor location was between the renal and iliac veins (low) (n = 4, 50%), between the hepatic and renal veins (middle) (n = 3, 38%), and above the hepatic veins with right atrial extension (high) (n = 1, 12%). Two patients with preoperative IVC occlusion were managed with tumor excision and IVC ligation. Three patients had primary repair of the IVC after tumor excision. A polytetrafluorothylene (PTFE) tube graft was used for IVC reconstruction in three cases. There was no postoperative mortality. Postoperative morbidity included deep venous thrombosis (DVT) (n = 1), lower extremity edema (mild n = 1; moderate n = 1), GI bleed (n = 1), and chronic renal insufficiency (n = 1). One patient is currently receiving adjuvant chemotherapy. Four patients received chemotherapy after recurrence, and one received palliative radiation therapy as well. Median survival to this point was 60 months with a median follow-up of 39 months. The 5-year overall survival and disease-free survival was 31 per cent for both (CI 0.1-1.0). The type of IVC reconstruction had no effect on survival (P = 0.22). Recurrence was discovered in four patients (50%) at a median time of 14 months. Resection of leiomyosarcoma of the IVC should be attempted whenever feasible. The management of the IVC can be managed with primary repair, ligation, or prosthetic graft. Long-term survival is possible if complete resection can be achieved.

We describe 3 cases of leiomyosarcoma of the inferior vena cava (IVC) and review the literature describing clinicopathologic features of 211 cases and the outcome. Of these, 74% of the cases affected women with median age of 52 years. The most common symptoms were abdominal pain or mass (57%), Budd-Chiari syndrome (17%), and deep vein thrombosis (4%). The most frequent site of tumor origin is the middle segment of the IVC (33%). Tumor size ranged from 2 to 38 cm (mean, 12 cm). Of the tumors with an assigned grade, 46% were high grade, 17% were intermediate grade, and 36% were low grade. Of all patients, 47% underwent complete resection, 24% had complete resection with preoperative or postoperative chemotherapy and/or radiation, and 5% had palliative surgery. Tumor recurrence occurred in 40% of the patients (11% had local recurrence and 29% had metastasis). Perioperative mortality occurred in 4% of the cases. Of those patients who died, 42% died of the disease, 2% died of other causes, 26% were alive and free of the disease, 14% were alive with recurrent disease, and 11% were lost to follow-up. Tumors involving level 2 of the IVC have the best prognosis and tumors of level 1 have the worse prognosis. Although there is no standardized criteria for the grading of extrauterine leiomyosarcoma, we propose to grade based on mitotic activity as follows: high grade, 10 or more mitoses per 10 high-power field (HPF); intermediate grade, 5 to 9 mitoses per 10 HPF; and low grade, 1 to 4 mitoses per 10 HPF.

Uterine artery embolization (UAE) is an increasingly performed, minimally invasive alternative to hysterectomy or myomectomy for women with symptomatic uterine fibroids. A growing body of literature documents symptomatic improvement in the majority of women who undergo UAE. Although UAE is usually safe and effective, there are a number of known complications associated with the procedure. Major complications include fibroid passage, infectious disease (endometritis, pelvic inflammatory disease-tubo-ovarian abscess, pyomyoma), deep venous thrombosis, pulmonary embolism, inadvertent embolization of a malignant leiomyosarcoma, ovarian dysfunction, fibroid regrowth, uterine necrosis, and even death. Minor complications include hematoma, urinary tract infection, retention of urine, transient pain, and vessel or nerve injury at the puncture site. As UAE takes its place in the treatment arsenal for women with symptomatic fibroids, radiologists need to be familiar with UAE-associated complications, which may require further treatment and may even be life threatening in some cases. Knowledge of these complications and their imaging features should lead to prompt diagnosis and appropriate treatment.

Leiomyosarcomas are rare malignant mesenchymal tumors. We report the case of a 55-year-old man with a lung metastasis from an iliofemoral leiomyosarcoma mimicking a deep venous thrombosis (DVT). Vascular leiomyosarcoma occurs in the wall of large vessels, and usually presents as unexplained DVT. To date, few cases of peripheral leiomyosarcomas have been described in the literature. This observation demonstrates the usefulness of Positron Emission Tomography (PET), beyond oncologic staging, in such indications as the workup of an unexplained DVT. In this report, PET prevented a misdiagnosis of DVT by showing a peculiar cockade appearance of the vessel. Compared with conventional imaging, PET can provide complementary information. The specificity of such information still needs to be assessed.

The authors report the clinical case of a 56 years old man who developed a deep venous thrombosis of the left lower extremity, managed conventionally with subcutaneous heparin. Physical examination revealed a large tumor of the middle third, antero lateral view of the left thigh. CT and NMR studies, disclosed an extensive multilobulated tumor along the femoral vessels, with medial deviation of the superficial femoral artery and a surgical biopsy revealed the diagnosis of leiomyosarcoma of the femoral vein, grade 3 of malignancy. The patient underwent a complete resection of the tumor, followed by chemotherapy. Two months after the operation a staging CT scan disclosed multiple micronodular metastasis in both lungs and six months later he was found asymptomatic and in good condition. A review of the literature concerning primary malignant tumors of the veins of the extremities is made, with emphasis on main features of its biology, clinical presentation, methods of diagnosis, treatment and results.
