This case study describes a 21-year-old woman who experienced intrathoracic fluid extravasation after hip arthroscopy. Irrigation fluid used during the procedure migrated into the retroperitoneal and thoracic regions, causing pleural effusions and respiratory symptoms. Computed tomography confirmed fluid accumulation in the chest and abdomen. Despite these findings, the patient remained hemodynamically stable and recovered fully. She also experienced hypothermia during the surgery, a known effect of fluid extravasation. A second hip arthroscopy six months later showed a suspected recurrence of fluid extravasation, but symptoms resolved again. The authors suggest that while rare, fluid extravasation is a clinically relevant complication of hip arthroscopy.
Area of Science:
Background:
Intrathoracic fluid extravasation is a rare but documented complication following hip arthroscopy. Prior research has shown that irrigation fluid used during arthroscopy can migrate beyond the surgical field. It was already known that fluid extravasation can lead to retroperitoneal and intraperitoneal collections. No prior work had resolved the full extent of physiological effects from this complication. This gap motivated the need to document and analyze individual cases. That uncertainty drove the collection of clinical observations and radiological findings. The literature suggests that fluid overload can cause transient hypothermia and respiratory compromise. However, the mechanisms remain incompletely understood.
Purpose Of The Study:
This study aimed to report a case of intrathoracic fluid extravasation following hip arthroscopy in a young patient. The specific problem involved fluid migration into retroperitoneal and intrathoracic regions. The motivation was to highlight the clinical manifestations and management of this rare event. The researchers propose that fluid overload can lead to pleural effusions and atelectasis. The authors also sought to compare this case with prior reports on fluid extravasation. They aimed to assess the physiological effects of fluid accumulation in the thoracic cavity. The study also examined whether symptoms resolved without long-term complications. The goal was to contribute to the understanding of irrigation fluid-related complications.
Main Methods:
The study involved a case report of a 21-year-old woman undergoing hip arthroscopy. Computed tomography was used to visualize fluid accumulation in the thoracic and abdominal regions. The researchers reviewed the patient's clinical course and radiological findings. They documented symptoms such as shortness of breath and hypothermia. The authors compared this case with other published reports on fluid extravasation. They analyzed the patient's hemodynamic stability and recovery process. The study also included a follow-up procedure on the contralateral hip. The researchers assessed whether fluid extravasation recurred during the second operation.
Main Results:
The patient developed retroperitoneal fluid and bilateral pleural effusions after hip arthroscopy. Computed tomography confirmed fluid collection in the chest and abdomen. The fluid caused diaphragmatic elevation and compression atelectasis. Despite these findings, the patient's hemodynamic status remained stable. She experienced hypothermia during the procedure, consistent with prior reports. The patient rapidly compensated for fluid overload and recovered fully. A second hip arthroscopy six months later showed suspected fluid extravasation again. Transient hypothermia occurred but resolved by the first postoperative visit.
Conclusions:
The authors suggest that intrathoracic fluid extravasation is a rare but clinically significant complication of hip arthroscopy. They propose that irrigation fluid can migrate into retroperitoneal and intrathoracic regions. The study highlights that fluid overload can cause respiratory compromise. The authors note that hemodynamic stability is often preserved despite fluid accumulation. They suggest that hypothermia is a common but transient effect of fluid extravasation. The findings indicate that symptoms may resolve spontaneously without long-term consequences. The researchers propose that recurrence is possible but not necessarily severe. The authors emphasize the importance of monitoring patients for fluid-related complications.
It is a rare complication where irrigation fluid used during surgery migrates into the thoracic cavity, causing pleural effusions and respiratory symptoms.
Computed tomography of the chest, abdomen, and pelvis revealed retroperitoneal fluid, ascites, and bilateral pleural effusions.
The authors suggest that fluid overload can lead to transient hypothermia, likely due to the large volume of irrigation fluid administered during surgery.
Computed tomography is used to visualize fluid accumulation in retroperitoneal, abdominal, and thoracic regions, confirming the extent of extravasation.
No long-term complications were observed; the patient's symptoms resolved spontaneously with no lasting effects.
The researchers propose that recurrence is possible but not necessarily severe, as seen in the second hip arthroscopy six months later.
