Delayed Complications Following Pacemaker Implantation

PACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 8 2002
KENNETH A. ELLENBOGEN
ELLENBOGEN, K.A., et al.: Delayed Complications Following Pacemaker Implantation. Acute complications resulting from permanent pacemaker implantation are well known and include perforation of the right atrium or right ventricle. Recently, several reports have described the occurrence of perforation and pericarditis as late complications following pacemaker implantation. These complications may occur days to weeks following uncomplicated pacemaker implantation and may lead to death if they are not recognized early. Five patients with late complications caused by active-fixation leads are reported and the clinical features of their presentation and management are reviewed. Late perforation of the right atrium or right ventricle is an uncommon complication after pacemaker implantation but should be suspected by the general cardiologist in a patient who has a device implanted within a week to several months prior to the development of chest pain.

Capsule Endoscopy in Examination of Esophagus for Lesions After Radiofrequency Catheter Ablation: A Potential Tool to Select Patients With Increased Risk of Complications

Capsule Endoscopy in Examination of Esophagus.,Background: Esophageal injury can result from left atrial radiofrequency ablation (RFA) therapy, with added concern because of its possible relationship to the development of atrial-esophageal (A-E) fistulas. Objective: Evaluate utility of esophageal capsule endoscopy to detect esophageal lesions as a complication of RFA therapy in the treatment of atrial fibrillation (AF). Methods: Consecutive patients with AF who underwent left atrial RFA therapy and received capsule endoscopy within 48 hours postablation. Video was reviewed by a single gastroenterologist. The medical records were also reviewed for symptoms immediately postablation and at the 3-month follow-up. Results: A total of 93 consecutive patients were included and 88 completed the study and were analyzed. The prevalence of esophageal lesions was 17% (15/88 patients). Nine percent (8/88) of these patients had lesions anatomically consistent with the location of the ablation catheter. Six patients with positive capsule findings had symptoms of chest pain (3/6, 50%), throat pain (2/6, 33%), nausea (1/6, 17%), and abdominal pain (1/6, 17%). An additional 24 patients were symptomatic postablation, but with normal capsule findings. All patients with identified lesions by capsule endoscopy received oral proton pump inhibitor therapy, and were instructed to contact the Cleveland Clinic in the event of worsening symptoms. No delayed complications were reported at the 3-month follow-up. Conclusion: This study supports the use of capsule endoscopy as a tool for the detection of esophageal injury post-RFA therapy. PillCam ESO is well tolerated and provides satisfactory images of the areas of interest in the esophagus without potential risk related to insufflation with regular esophagogastroduodenoscopy.

Iatrogenic vertebral artery injury

Iatrogenic vertebral artery injury (VAI) results from various diagnostic and therapeutic procedures. The objective of this article is to provide an update on the mechanism of injury and management of this potentially devastating complication. A literature search was conducted using PubMed. The iatrogenic VAIs were categorized according to each diagnostic or therapeutic procedure responsible for the injury, i.e., central venous catheterization, cervical spine surgery, chiropractic manipulation, diagnostic cerebral angiography, percutaneous nerve block, and radiation therapy. The incidence, mechanisms of injury, and reparative procedures were discussed for each type of procedure. The type of VAI depends largely on the type of procedure. Laceration was the dominant type of acute injury in central venous catheterization and cervical spine surgery. Arteriovenous fistulae and pseudoaneurysms were the delayed complications. Arterial dissection was the dominant injury type in chiropractic manipulation and diagnostic cerebral angiography. Inadvertent arterial injection caused seizures or stroke in percutaneous nerve block. Radiation therapy was responsible for endothelial injury which in turn resulted in delayed stenosis and occlusion of the vertebral artery (VA). The proximal VA was the most vulnerable portion of the artery. Although iatrogenic VAIs are rare, they may actually be more prevalent than had previously been thought. Diagnosis of iatrogenic VAI may not always be easy because of its rarity and deep location, and a high level of suspicion is necessary for its early detection. A precise knowledge of the surgical anatomy of the VA is essential prior to each procedure to prevent its iatrogenic injury. [source]

1235: How to prevent postoperative complications?

ACTA OPHTHALMOLOGICA, Issue 2010
C CREUZOT
Purpose Retinal detachment can lead to early and delayed post-operative complications. The purpose of the course is to present the different complications following retinal detachment surgery with their appropriate treatments. Methods The postoperative complications will be divided according to the presentation of the patient (ie inflamed, painful eye or white painless eye) with or without visual loss.Then, IOP measurement and the results from slit lamp and fundus exam will provide us with the main signs useful for diagnosis. Results With a painful red eye, the main severe diagnoses will be the different causes of increased IOP and endophthalmitis. The main cause of increased ocular pressure is related to the internal tamponade used during surgery (gas or silicone). However, the diagnosis of massive passage of silicone in the anterior chamber should be difficult. Hyphema or cataract due to gas should prevent us from a good fundus examination. Conclusion This course will mainly focus on the different early and more delayed complications after retinal detachment surgery and will try to give some rules to decrease this risk. [source]
