A successful right axillary artery graft to repair a ruptured axillary artery due to the involvement of lymphoma: report of a case

A case of nodal malignant lymphoma presenting with arterial bleeding related to its duodenal penetration

A 62-year-old man with a chief complaint of dysphagia visited our hospital. Enhanced computed tomography showed the tumor near the duodenal wall and lymphadenopathy in the left supraclavicular fossa and para-aortic lymph node. Upper gastrointestinal endoscopy showed an ulcer accompanied with a fistula in the anterior wall of duodenal bulb, suggesting that the tumor penetrated into duodenal wall. Biopsy from the lymph node in the left supraclavicular fossa indicated diffuse large B-cell lymphoma. Although chemotherapy was planned, massive arterial bleeding occurred from the part of duodenal penetration. Endoscopic hemostasis was unsuccessfully performed. Therefore, we performed transcathether arterial embolization for hemostasis. After the procedure, the patient received six cycles of chemotherapy, and he achieved complete response. He has been alive 5 years without recurrence. There were many cases of gastrointestinal bleeding from primary gastrointestinal lymphomas, while there were few cases with nodal involvement by malignant lymphoma resulting in bleeding from gastrointestinal tract. We herein report a case of duodenal bleeding by nodal involvement of diffuse large B-cell lymphoma with review of literature.

Emergency endovascular management of the common femoral artery rupture due to radiotherapy for scrotal carcinoma

We describe the case of a 72-year-old man with massive hemorrhage and shock resulting from rupture of the left common femoral artery as a complication of radiotherapy in the groin for cancer of the scrotum. This complication is extremely rare, presents dramatically, and is usually fatal. The patient was successfully treated with a stent graft deployment in order to achieve immediate hemostasis maintaining blood flow to the leg. Open surgery is not ideal in those cases especially when there is extensive tumor involvement of the groin causing altered anatomy and increasing the risk of re-bleeding.

Non-Hodgkin lymphoma as a cause of obstructive jaundice with simultaneous extrahepatic portal vein obstruction: A case report

Non-Hodgkin lymphoma is a rare cause of biliary obstruction. To the best of our knowledge, non-Hodgkin lymphoma in the peripancreatic region causing obstructive jaundice with simultaneous portal vein (PV) invasion has not yet been reported. We present a 50-year-old patient with obstructive jaundice whose extrahepatic portal vein was obstructed by the invasion of a peripancreatic non-Hodgkin lymphoma. The patient denied any other symptoms such as recurrent fever, night sweat and loss of body weight. Computed tomography (CT) revealed a 10 cm mass in the retroperitoneal space behind the head of the pancreas causing obstruction of the distal bile duct and the PV. A pylorus-preserving pancreaticoduodenectomy combined with a PV resection was performed. The PV was reconstructed using an autologous right internal jugular vein graft. The resected specimen showed endoluminal invasion of both the bile duct and the PV. Histological examination showed the mass consisting of diffuse sheets of large malignant lymphoid cells. These cells were positive for CD20 and CD79a, partially positive for CD10, and negative for CD3, CD4, CD5, CD8 and CD30. The pathologic diagnosis was diffuse large B-cell type non-Hodgkin lymphoma and the patient was transferred to the Department of Hematology and Oncology for chemotherapy. He received four cycles of combined chemotherapy including cyclophosphamide, doxorubicin, vincristine and prednisone plus rituximab, and three cycles of intrathecal chemoprophylaxis including methotrexate, cytosine arabinoside and prednisone. The patient is alive with no evidence of the disease for 7 mo after operation and will receive additional courses of chemotherapy.

Arterial reconstructions associated with the resection of malignant tumors

OBJECTIVE

When trunk arteries are affected by malignant neoplasia, and surgical treatment involving tumor and arterial resection is used, the vascular reconstruction must be performed immediately to avoid ischemia in the brain and large tissue masses. The objective of this study was to analyze the results obtained with the treatment of patients with malignant neoplasia who underwent tumor and vascular resection associated with arterial reconstruction. The primary patency of reconstructions, the occurrence arterial complications, and patient survival were assessed.

METHODS

Thirty-six patients with cervical, abdominal, or lower limb neoplasias were followed up. These patients underwent elective operations at Hospital do Câncer A.C. Camargo, São Paulo, between September 1997 and September 2004. They were divided into 3 groups according to tumor location: Cervical (14), lower limbs (13), and Abdomen (9). Thirty-eight arterial reconstructions were performed in these 36 patients.

RESULTS

There were 5 arterial complications: 2 early- and 3 late-stage. The early complications consisted of 1 symptomatic carotid occlusion with sequelae and 1 femoral graft rupture without sequelae. The late-stage complications consisted of 1 symptomatic carotid occlusion, 1 occlusion of an axillary-carotid graft, and 1 occlusion of a branch of the aortobifemoral graft, all without sequelae. There was no difference between the primary arterial patency rates. All the deaths (22) resulted from progression of neoplasic disease.

CONCLUSIONS

Arterial reconstructions associated with resection of malignant neoplasia in cervical, abdominal, or lower limbs can be carried out with low rates of morbidity and mortality. There was no difference in the primary arterial patency rates among the groups studied.
