Case Reports
Spontaneous migration of a Port-a-Cath catheter into ipsilateral jugular vein in two patients with severe cough.
Port-A-Cath systems are widely used for long-term therapy in the treatment of malignancies and infection. Spontaneous migration of Port-A-Cath catheters after satisfactory initial placement is uncommon but is associated with a number of complications, including neck pain, shoulder pain, ear pain, infection, venous thrombosis, and neurological complications. We describe two cases of migration of the Port-A-Cath catheter into the ipsilateral internal jugular vein. ⋯ We also review the literature regarding such unusual complications of Port-A-Cath. Because catheter migration might be asymptomatic, monitoring the catheter position bimonthly when not used is recommended. Before a new course of chemotherapy or encountering symptoms of migration, obtaining a chest roentgenogram is essential to provide early detection and repositioning management of a migrated catheter.

Visceral (mesenteric and/or renal) ischemia/reperfusion phenomena likely contribute to the greater operative risk associated with pararenal and lower thoracoabdominal aortic aneurysm (TAA) repair. To differentiate the relative adverse effects of aortic clamp level, visceral ischemic duration, and various pre- and perioperative factors shared with infrarenal aneurysm patients, a comparative analysis of early and late outcomes after open repair of intact infrarenal and visceral aortic aneurysms was undertaken. A retrospective review of our university experience from 1993-1999/2002 revealed 549 patients (mean age 70 +/- 8 years, 11% female) undergoing open repair of intact, degenerative aneurysms of the infrarenal (n = 391, 71%), juxtarenal (n = 78, 14%), suprarenal (n = 35, 7%), and type IV (n = 40, 7%) and type III (n = 5, 1%) TAA segments. ⋯ Five-year survival rate was similar after visceral aortic (70%) and infrarenal (75%) repairs but negatively impacted only in patients with prior infrarenal abdominal aortic aneurysm repair and recurrent aneurysms (OR = 2.8, 95% CI 1.2-6.9). The high incidence of early adverse outcomes following repair of pararenal and lower thoracoabdominal aneurysms is primarily associated with excessive periods of renal and/or gut ischemia during visceral aortic clamp placement. However, nearly equivalent early and late survival was seen for visceral aortic and infrarenal repairs when VIT < 32 min was achieved.

We assessed the impact on patient outcomes of comorbidities and type of aneurysm repair, open vs. endovascular aortic repair (EVAR). Functional health status was measured prospectively using the Short Form 36 (SF-36) Health Survey. Length of stay (LOS) and need for postdischarge resources (nursing and rehabilitation) were compared between groups. ⋯ Those patients undergoing abdominal aortic aneurysm (AAA) repair by open technique (compared to EVAR) had significantly impaired functional health with regard to PF, VT, and ER in the first 3 months after surgery. CHF and hypertension also significantly impaired individual functional health scores. Of significance was that female gender was associated with increased LOS and increased utilization of postdischarge nursing and rehabilitation resources following both open and endovascular surgery for AAA.

Acute distal aortic dissection sometimes causes one or more visceral vessels to be stenosed by the thrombosed false lumen. Although stenosis of the only celiac artery (CA) usually does not cause ischemic symptoms because of the extensive collateral pathways of the mesenteric circulation, we experienced a rare case of CA compression syndrome which was caused by acute type B aortic dissection. ⋯ We treated the patient with percutaneous transluminal angioplasty in the CA. This report indicates that attention should be given to the possibility of CA compression syndrome in the case of acute distal aortic dissection and that endovascular management can be successfully applied to control symptoms caused by the syndrome, which is otherwise extremely difficult to repair directly by surgery.

The case of a patient with blunt traumatic internal carotid artery dissection associated with subocclusive stenosis and thromoboembolic complication is presented. The patient suffered fluctuant neurological abnormalities and several open and closed fractures of the left limb. The vascular lesion and its complication were successfully treated with intraarterial thrombolysis and stent placement during the acute phase, prior to the open surgical treatment of the fractures.
