Human chorionic Gonadotropin (HCG) therapy has been used beneficially in men with subfertility especially after varicocele surgery. Very few side effects have been observed in male patients. Herein, we report a case of pulmonary embolism in a male patient following the use of HCG. The patient was subsequently found to have type IV hyperlipoprotenemia. The etiology of the thrombo-embolic episode is conjectural, but this case emphasizes the need for stricter criteria of patient selection and screening for conditions that predispose to thrombo-embolism before starting HCG therapy.

One encounters a variety of radiopaque foreign objects when reviewing plain film radiographs of the abdomen. Recognizing such devices can offer important clues about a patient's medical history. Accordingly, intrauterine contraceptive devices (IUCD), tubal sterilization, varicoceles, inferior vena cava (IVC) filtration, and vaginal pessaries are discussed with reference made to an IUD, tubal sterilization clips, embolization coils for bilateral varicoceles, an IVC filter, and a vaginal pessary in five attached anteroposterior radiographs of the lower abdomen and pelvis for five different patients. IUCDs confer long-term, passive, reversible, and inexpensive protection against unwanted pregnancy. They may, however, induce menstrual complications as well as an increased risk of pelvic inflammatory disease and ectopic pregnancy. They can also be spontaneously expelled from the uterus without being noticed by the client. An IUCD increases the risk of spontaneous abortion unless removed in cases where intrauterine pregnancy occurs. Complications at the time of insertion include pain, syncope, and uterine perforation. Tubal sterilization is an effective, though largely irreversible method of contraception. Complications include an increased risk of ectopic gestation in the event of pregnancy and the usual risks of hemorrhage, infection, injury to adjacent structures, and anesthesia-related complications. A varicocele is a dilation of the pampiniform venous plexus of the scrotum. They are more often unilateral than bilateral, occurring in up to 20% of men most often on the left side. Although most cases are probably insignificant, varicoceles can decrease sperm count and motility and cause abnormal morphology. Correction of varicoceles has been shown to improve sperm quality and can increase the chances of fertility. Percutaneous venous embolization techniques have recently been developed to that end. Procedural risks include perforation of the vein, intimal dissection, inadvertent embolization of vessels via collateral channels, and reactions to contrast media. IVC filters are a feasible alternative treatment for deep venous thrombosis and pulmonary embolism among patients in whom anticoagulants are contraindicated or for those in whom anticoagulation therapy has failed. Introduced via the femoral or jugular veins, they are permanent metallic devices placed within the lumen of the IVC to filter thrombi which migrate from the deep veins of the lower extremities. Contraindications to IVC filter insertion include severe coagulopathy and thrombosis involving all venous access routes, while complications include hematoma at the insertion site, migration or tilting of the device due to poor anchoring in the IVC wall, and vena cava obstruction. A pessary is a prosthetic device used to support pelvic structures when their natural support is lacking. They are usually made of plastic or rubber and inserted into the vagina to aid in the non-operative treatment of uterine prolapse, proctoceles, and cystoceles. They must be properly fitted and removed every few months for cleaning.

After a brief reference to the most important pioneers of angiography, the author describes the techniques performed, lesions treated and future perspectives. The following techniques are performed: embolizations, selective infusion of drugs, placement of inferior vena cava filter, removal of intra-vascular bodies, revascularisation techniques and porta-cava shunt. Reference was made to the following lesions treated: tumours, hemorrhages, arteriovenous malformations, hypersplenism, pulmonary embolism, varicocele, ischemic lesions and portal hypertension.

Interventional radiology employs image-guided techniques to perform minimally invasive procedures for diagnosis and treatment. Interventional radiology is often used to place central venous catheters and subcutaneous ports, with some evidence of benefit over surgical placement. Arterial embolization procedures are used to manage many types of hemorrhage and are highly effective for severe postpartum hemorrhage. Vascular interventions, such as endovascular treatment of varicosities, acute limb ischemia, and pulmonary embolism, are superior to surgical interventions. For chronic limb ischemia and deep venous thrombosis, the choice of therapy is not as clear. Inferior vena cava filters can be placed and removed endovascularly, but there is a significant risk of complications that increases over time. Vascular interventions can be effective for scrotal varicocele and uterine fibroids, although fibroid treatment is limited by high recurrence rates. Image-guided percutaneous drainage and biopsy have become standard of care. Interventional approaches are being used in oncology for local diagnosis and treatment. Percutaneous ablation and targeted delivery of chemotherapy and radiation therapy are being developed as alternatives when surgery is not practical. Vertebroplasty and kyphoplasty provide significant pain and functional improvement in patients with spinal metastases.
