Aortic endograft surveillance is a necessity for the lifetime of a patient owing to the risk of endoleaks and device complications. The current standard of care for surveillance is radiologic imaging. The most commonly used modality is computed tomographic angiography. Magnetic resonance angiography and ultrasonography have also been used as surveillance tools. These imaging techniques have risks and limitations, and alternative surveillance tools are being investigated. Remote pressure sensing is a promising technology that can provide adjunctive support to the current imaging modalities. The technology is applicable to both abdominal and thoracic endograft implantation and surveillance. It has recently gained clearance from the US Food and Drug Administration for acute aneurysm exclusion during an abdominal endograft insertion. As more data are accumulated, it may be possible for remote pressure sensing to replace current imaging techniques as the sole modality for endograft surveillance.

Purpose: To report emergent endovascular repair of a ruptured abdominal aortic aneurysm (AAA) in a patient with a horseshoe kidney. Case Report: A 78-year-old man with a horseshoe kidney presented with a contained rupture of a 72-mm AAA. After urgent computed tomographic angiography (CTA) documented the blood supply to the kidney and the suitability of the aneurysm for endovascular repair, the patient was given a local anesthetic. An aortomonoiliac stent-graft constructed from components provided in a Talent Acute Endovascular Aneurysm Repair Kit was inserted successfully. The procedure was completed with placement of a contralateral common iliac artery occluder and a femorofemoral bypass graft. No complications were encountered, and the patient was discharged with an excluded aneurysm on the fourth postoperative day. At 3 months, aneurysm exclusion was confirmed by CTA, and no endoleak was present; the retroperitoneal hematoma had disappeared. The patient remains in good general condition 8 months after treatment Conclusions: The advantages of endovascular aneurysm repair in the emergency setting can facilitate rapid recovery in patients with symptomatic or ruptured aneurysms, especially those having a horseshoe kidney.

This study evaluated the value of computed tomographic angiography (CTA) early after an endovascular aneurysm repair (EVAR) in relation to CTA 3 months after EVAR. We retrospectively reviewed all elective EVAR patients with available postprocedural and 3-month follow-up CTAs who were treated between 1996 and 2006. CTAs were analyzed for EVAR-related complications in terms of endoleaks, migration, and stent graft thrombosis. Secondary procedures and other complications within a 4-month time interval after EVAR were noted and analyzed for any association with the postprocedural CTA. During the study period, 291 patients (275 men), with a mean age of 71 years, underwent elective EVAR. All had postprocedural and 3-month follow-up CTAs, which detected 93 (32%) endoleaks (8 type I, 84 type II, 1 type III) and 1 stent graft thrombosis. These findings resulted in four secondary interventions (one interposition cuff, two extension cuffs, one conversion). All reinterventions were successfully done in an elective setting. During the first 3 postoperative months, five other reinterventions were required for acute ischemia in four patients (three Fogarty procedures, one femorofemoral crossover bypass) or groin infection in one patient. Eight patients died, but none of the deaths were related to abdominal aortic aneurysm or EVAR (four cardiac, two pulmonary, one gastric bleeding, one carcinoma). At 3 months, 43 endoleaks (3 type I, 40 type II), 3 stent graft thromboses, and 1 stent graft migration were seen. In two patients (0.7%), a new endoleak was diagnosed compared with the postprocedural CTAs. In 287 (99%) of 291 patients, the postprocedural CTA did not influence our treatment policy in the first 3 months after EVAR. More than half of the early endoleaks were self-limiting, and new endoleaks were seen in only two patients (< 1%) at the 3-month follow-up CTA. After an uneventful EVAR procedure, it is safe to leave out the early postprocedural CTA.

We present the case of a 90-year-old diabetic male and medically managed three-vessel coronary artery disease with evidence of an oval, nonmobile echo-density located on the posterior mitral valve annulus measuring two centimeters in diameter without significant impingement of the mitral valve on initial screening echocardiogram which was initially thought to be prominent mitral annular calcification which was later confirmed to be a rare case of caseoma as confirmed by both cardiac magnetic resonance (CMR) as well as coronary computed tomographic angiography (CCTA).

CT angiography (CTA) has improved significantly over the past few years such that the reconstructed images of the cerebral arteries may now be equivalent to conventional digital angiography. The new technology of 64 slice multi-detector CTA can reconstruct detailed images that can reliably identify small cerebral aneurysms, even those &lt;3mm. In addition, it is estimated that CT followed by lumbar puncture (LP) misses up to 4% of symptomatic aneurysms. We present a series of cases that illustrates how CT followed by CTA may be replacing CT-LP as the standard of care in working up patients for symptomatic cerebral aneurysms and the importance of performing three dimensional (3D) reconstructions. A series of seven cases of symptomatic cerebral aneurysms were identified that illustrate the sensitivity of CT-CTA <em>versus</em> CT-LP and the importance of 3D reconstruction in identifying these aneurysms. Surgical treatment was recommended for 6 of the 7 patients with aneurysms and strict hypertension control was recommended for the seventh patient. Some of these patients demonstrated subarachnoid hemorrhage on presentation while others had negative LPs. A number of these patients with negative LPs were clearly symptomatic from their aneurysms. At least one of these cerebral aneurysms was not apparent on CTA without 3D reconstruction. 3D reconstruction of CTA is crucial to adequately identify cerebral aneurysms. This case series helps reinforce the importance of 3D reconstruction. There is some data to suggest that 64 slice CT-CTA may be equivalent or superior to CT-LP in the detection of symptomatic cerebral aneurysms.
