Solitaire AB stent mechanical embolization combined with catheter contact thrombolysis for acute renal artery embolism: A case report.

Acute renal artery embolization is a rare disease resulting in interruption of blood flow, resulting in renal tissue ischemia or necrosis, and even developing into acute renal failure. It is urgent to diagnose timely, recanalize the occluded renal artery early, and recover renal blood perfusion. Here, the article reports a case of acute renal artery embolization, which was successfully cured by interventional therapy.

Pulmonary cryptococcosis misdiagnosed as lung cancer in a man with normal immune function: A case report.

Pulmonary cryptococcosis is an opportunistic infection of cryptococcus both in immunocompetent and immunocompromised patients, who suffered from HIV infection, organ transplantation, diabetes mellitus, corticosteroid or immunosuppressive therapy, and malignancy. Pulmonary cryptococcosis is the commonest location of non-central nervous system cryptococcosis and usually presents with nonspecific symptoms. It often shows shadows on the lung, which makes it difficult to distinguish it from lung cancer. Here we report a case of a 52-year-old man with pulmonary cryptococcosis, who was misdiagnosed as lung cancer. Clinicians need to consider the possibility of pulmonary cryptococcosis and the importance of lung biopsy when treating a patient with a normal immune function that has isolated pulmonary nodules. This case also indirectly illustrates the importance of percutaneous lung biopsy in patients with isolated pulmonary nodules.

Transarterial chemoembolization for Kasabach-Merritt syndrome caused by hepatic angiosarcoma: A case report.

Hepatic angiosarcoma is a rare disease, and hepatic hemangiosarcoma with Kasabach-Merritt syndrome (KMS) is even rarer. Although there have been several reports about KMS caused by hepatic angiosarcoma, there has been no mention of successful treatment regimens for hepatic angiosarcoma with KMS. A 64-year-old female patient presented with right upper abdominal pain and multiple cutaneous purpuras for 10 days. Blood analysis revealed that hemoglobin, platelet and fibrinogen were significantly decreased, prothrombin time was prolonged, fibrinogen degradation products were increased. Contrast-enhanced computed tomography scan of the abdomen demonstrated a large mass in the right lobe of the liver, which is pathologically suggestive of hepatic angiosarcoma. Based on the above examination, the patient was diagnosed with KMS caused by hepatic angiosarcoma. Repeated transfusion of blood products could only temporarily improve the coagulation function of the patient.  After transarterial chemoembolization, the patient experienced a long-term improvement of blood clotting, and the patient's survival increased by six months. Transarterial chemoembolization should be considered one of effective therapies for hepatic angiosarcoma with KMS.

Superselective Arterial Embolization of Arteriovenous Malformation of Internal Pudendal Artery, a Rare Cause of Hematuria: A Case Report.

Arteriovenous malformation (AVM) is a common form of vascular malformation, an abnormal direct communication between an artery and a vein without passing through the capillaries. AVM may just present as hematuria without plain or other symptoms. The article presents a case of a 52-year-old male with gross hematuria diagnosed as AVM of internal pudendal artery, which was successfully managed with superselective arterial embolization using temporary embolization materials.
