Management of brachial artery occlusion after cardiac catheterization
Insights
Early detection and surgical repair of brachial artery injury after cardiac catheterization are crucial. Prompt operative management, including resection and anastomosis, restores circulation in 97% of patients, minimizing complications.
Area of Science:
- Vascular Surgery
- Interventional Cardiology
- Patient Management
Background:
- Brachial artery injury is a potential complication of cardiac catheterization.
- Accurate diagnosis and timely intervention are essential for optimal patient outcomes.
Purpose of the Study:
- To report the management and operative outcomes of patients with suspected brachial artery injury post-cardiac catheterization.
- To establish diagnostic criteria and recommend surgical techniques for brachial artery injury.
Main Methods:
- Retrospective review of 42 patients undergoing operative management for brachial artery injury.
- Clinical assessment including pulse palpation and Doppler-measured forearm pressures.
- Surgical techniques: brachial artery exploration, resection with end-to-end anastomosis, or "plastic" repair.
Main Results:
- Absence of distal radial pulse or a 30-mm Hg pressure difference indicated occlusion.
- Resection with end-to-end anastomosis yielded good results, while "plastic" repair often led to reobstruction.
- 97% of patients achieved adequate circulation restoration within 24 hours of surgery.
- Doppler-measured arterial pressures were valuable for pre- and post-operative evaluation.
Conclusions:
- Early diagnosis of brachial artery injury can be achieved through clinical assessment and Doppler pressures.
- Surgical resection with end-to-end anastomosis is the preferred method for managing brachial artery injury.
- Early surgical repair of confirmed brachial artery injuries leads to good outcomes and low morbidity.
Abstract:
Our management of patients with suspected brachial artery injury following cardiac catheterization and the results of operative management in 42 patients are reported. From this review the following suggestions or conclusions are made: 1) The absence of a distal radial pulse or a 30-mm Hg difference in forearm pressures four hours after brachial artery catheterization is indicative of a pathologic occlusion at the site of catheterization. 2) Adequate anticoagulation with heparin should be used during the observation period. 3) When indicated, reexploration of the brachial artery should be performed in the operating room using local anesthesia. 4) Resection of a segment of injured brachial artery with an end-to-end anastomosis using interrupted sutures gives good results. Attempts at "plastic" repair without resection were ususlly accompanied by reobstruction. 5) Arterial pressures in both arms, as monitored with a Doppler instrument before and after exercise, were of value in evaluating these patients pre- and postoperatively. 6) No preoperative arteriograms were required. 7) Restoration of adequate circulation was achieved in 97 per cent of patients operated on for brachial artery injury within 24 hours of cardiac catheterization and using the techniques described. 8) The good operative results and low morbidity suggest early repair for all confirmed brachial artery injuries.
