The macroscopic features of the venous drainage of the reproductive system of the male ostrich were studied in six pre-pubertal and three sexually mature and active birds. Each testis was drained by one to four testicular veins. The right testicular veins drained the right testis and epididymis and its appendix to the caudal vena cava and to the right common iliac vein, whereas the left testicular veins drained the left testis and epididymis and its appendix exclusively to the left common iliac vein. A number of variations in the drainage pattern based on the point of entry and number of testicular veins were observed. The cranial aspect of the testis was also linked to the caudal vena cava or common iliac vein via the adrenal veins. The cranial, middle and caudal segments of the ductus deferens (and ureter) were drained by the cranial, middle and caudal ureterodeferential veins respectively, to the caudal testicular veins, the caudal renal veins and pudendal / caudal part of the internal iliac veins. In some specimens, the caudal ureterodeferential veins also drained into the caudal mesenteric vein. The surface of the phallus was drained by tributaries of the pudendal vein. The basic pattern of venous drainage of the reproductive organs of the male ostrich was generally similar to that described for the domestic fowl. However, important differences, including the partial fusion of the caudal renal veins, drainage of the cranial aspect of the testes via the adrenal veins, drainage of the caudal ureterodeferential veins into the caudal mesenteric vein and the presence of veins draining the surface of the phallus, were observed. Although significant, these differences may simply reflect variations in the normal pattern of venous drainage of the reproductive tract of birds which could be verified by studying more specimens and more species.

The iliocaval compression syndrome is a disorder, frequently found in young women, in which extrinsic compression of the left iliocaval junction produces signs and symptoms of lower extremity venous insufficiency. The anatomic variant which gives rise to this syndrome consists of compression of the left common iliac vein by the overlying right common iliac artery, near its junction with the vena cava. Additional reduction of outflow results from intraluminal venous webs and tight adhesions between the iliac artery and vein. Pain, swelling, pigmentation, and venous claudication characterize this syndrome, which affects predominantly the left leg. The syndrome may progress to iliofemoral thrombosis, phlegmasia cerulea dolens, and venous gangrene. Longstanding iliocaval stenosis may produce valvular incompetence. Exercise plethysmography is a non-invasive test useful in screening patients for iliocaval compression. The definitive diagnosis is made by venography, both ascending and descending, to determine the degree of outflow stenosis. Iliocaval patch angioplasty with retrocaval positioning of the right iliac artery, decreases venous hypertension and leads to improvement in the clinical condition. To date, we have performed iliocaval angioplasty, with retrocaval repositioning of the right common iliac artery, on 18 patients. Of these, 83% have had good results as determined by hemodynamic and clinical assessment.

Case Basis

Abstract Pedicle screws are commonly used in spinal surgeries and are relatively safe, with venous complications occurring rarely. We report a patient with imaging following a L4–5 fusion that showed indentation of the inferior vena cava and right common iliac vein by the right L4 and L5 pedicle screws. She underwent revision surgery in which the hardware was removed and no bleeding was observed. Intraoperative venogram confirmed vascular integrity and absence of indentation on the venous structures following screw removal. The patient recovered without complications. Venous contact by pedicle screws should be treated on a case-by-case basis in a multidisciplinary approach with vascular surgery. We discuss a treatment algorithm for the operative management of this problem.

The purpose of this article is to describe our experience with the retrievable OptEase inferior vena cava filter (IVCF) (Cordis Corporation, Miami Lakes, FL) in the prevention of pulmonary embolus (PE). Forty patients (24 men, age range 15–85 years, mean age 38 years) who were at temporary risk of PE underwent insertion and retrieval of the OptEase IVCF at two institutions. Eleven patients were treated with filter implantation and subsequent repositioning in the inferior vena cava (IVC) to extend implantation time. All patients were followed up for 24 hours after retrieval, with additional follow-up at the physician's discretion. Forty patients had successful filter insertion. Two patients who underwent intravascular ultrasound guidance for filter deployment required filter repositioning within 24 hours owing to inadvertent placement in the right common iliac vein. All 40 patients underwent successful filter retrieval with no adverse events. In those patients who did not undergo IVCF repositioning, the time to retrieval ranged from 3 to 48 days (mean ± SD 16.38 ± 7.20 days). One patient had a successful retrieval at 48 days, but all other retrieval experiences were performed within 23 days. The second strategy involved implantation, with repositioning at least once before final retrieval. This latter strategy occurred in 11 patients, and the time to first capture ranged from 4 to 30 days (mean ± SD 13.82 ± 6.13 days). No symptomatic PE, IVC injury or stenosis, significant bleeding, filter fracture, or filter migration was observed. In this feasibility study, the OptEase IVCF prevented symptomatic PE, was safely retrieved or repositioned up to 48 days after implantation, and served as an effective bridge to anticoagulation. In patients who require extended IVCF placement, the OptEase IVCF can be successfully repositioned within the IVC, thereby extending the overall implantation time of this retrievable IVCF.

Retrieval of a Gunther tulip vena cava filter implanted in a patient with inferior vena cava and right common iliac vein thrombosis was attempted by the standard method. Because the filter was tilted, the hook became attached to the vena cava wall and could not be snared. During attempts at removal by an alternative method, the filter migrated toward the right atrium. However, it was finally successfully removed.

Background. A rare case of low-grade endometrial stromal sarcoma (LG-ESS) extending to inferior vena cava (IVC) and cardiac chambers.Case Report. A 40-year-old woman had IVC tumor, which was incidentally detected by abdominal ultrasonography during a routine medical checkup. CT scan revealed a tumor in IVC, right iliac and ovarian veins, which was derived from the uterus and extended into the right atrium and ventricle. The operation was performed, the heart and IVC were exposed, and cardiopulmonary bypass was initiated. A right atriotomy was performed, and the intracardiac mass was removed. Then the tumor in IVC and the right internal iliac vein were removed after longitudinal venotomies in the suprarenal and infrarenal vena cava, the right common iliac vein. Next the pelvis was explored. Tumors were found originating from the posterior wall of the uterus and continuing into both the right uterine and ovarian vein. The patient underwent total hysterectomy with bilateral salpingooophorectomy. Complete tumor resection was achieved. Histopathological analysis confirmed a diagnosis of LG-ESS. She showed no evidence of disease for 2 years and 3 months.Conclusions. Our case highlights the importance of a multidisciplinary approach in treating this rare cardiovascular pathological condition through preoperative assessment to final operation.

Duplication of the inferior vena cava (IVC) resulting in an accessory left-sided IVC is a relatively rare vascular anomaly with a reported prevalence of 0.7%. Radiologically, a duplicated left-sided IVC is usually seen as a continuation of the left common iliac vein, crossing anterior to the aorta at the level of the renal vein to join the right-sided IVC. We present a rare case in which an accessory left-sided IVC was discovered intraoperatively, in a 47-year-old living donor, posing significant intraoperative challenges regarding extraction and subsequent transplantation.

A 10-year-old, spayed female, mixed-breed dog was referred for evaluation of bilateral hindlimb edema and weakness. Abdominal ultrasonography showed increased echogenicity of the lumen of the caudal vena cava from the level of the urinary bladder to the level of the cranial pole of the right kidney. Bilateral saphenous venograms displayed numerous filling defects in the caudal vena cava, right external iliac vein, right femoral vein, and the right common iliac vein. Extensive venous thrombosis was diagnosed, and the animal was euthanized. Necropsy confirmed the presence of venous thrombosis and revealed a right adrenocortical carcinoma that had invaded the caudal vena cava.

Abstract We present the case of a 63-year old woman with previous history of high-grade liposarcoma. of the lower extremity. She had been treated with radiotherapy and chemotherapy and then she underwent surgical treatment with wide local excision several months ago. She was awaiting a new surgical procedure to remove a right suprarrenal metastasis. The patient presented with lower extremity edema and abdomen and increasing weight in the previuos week. A thoracic and abdominal CT showed the suprarrenal mass had become of greater size. Enlargement of superior vena cava, partial filling defects in several segments of the right lung suggestive of acute pulmonary embolism. Extensive thrombosis from right iliac vein, common iliac vein, intrahepatic cava vein, inferior vena cava, right atrium and right ventricle. Bilateral pleural effusion and ascites. A transthoracic echocardiogram revealed a big mass (6.1 cm) in the right atrium prolapsing into the right ventricle. There was a mean diastolic gradient of 3 mmHg and maximal gradient of 6 mmHg in the tricuspid valve. Left ventricle systolic function was moderately depressed due to abnormal movement of the interventricular septum suggestive of pulmonary hypertension. The clinical course was characterized by rapid deterioration and the patient died from cardiogenic shock. The source of thrombi in the right side of the heart most of the times is venous thrombi that have embolized. Cancer patients have an increased risk of venous thromboembolism compared with the general population. The risk varies depending on the type and the stage of the cancer. Metastatic disease has the highest risk. Most clinically significant pulmonary embolisms originate as venous thromboembolism in the lower extremities or pelvic veins. However in most of the cases it is difficult to image the thrombus "in-transit". In this case the most striking feature is not imaging the thrombus "in-transit" but its massive size.

Preventive Methods

Pulmonary embolism remains a fatal and frequent complication of thromboembolic disease despite the development of preventive methods. Cancer patients are at higher risk of thromboembolism than those in the general population [1]. The thoracic CT angiography is the standard examination; it makes the diagnosis with certainty by showing the endoluminal thrombus. Saddle pulmonary embolism is a radiological term; it is defined by the presence of a thrombus overlapping the bifurcation of the main pulmonary artery extending to both right and left. It represents 2 to 5% of pulmonary embolisms [2]. We present the image of a hemodynamically stable 69-year-old patient followed for adenocarcinoma of the prostate who was referred in our training to a thoraco-abdomino-pelvic scanner for assessment and evaluation of his pathology. The chest CT revealed a hypo dense endoluminal thrombus of the pulmonary artery trunk extended to its right and left dividing branches (Figure 1). Abdominal sections showed an endoluminal thrombus of the right common iliac vein extending to the inferior vena cava (Figure 2).
