Implication

Hiatal hernia compression may cause pulmonary vein thrombosis and cerebral embolism post-lobectomy despite short stump; leaves open need for confirmatory studies.

Key Points

  • To investigate the occurrence of cerebral embolism due to pulmonary vein stump compression after left lower lobectomy in a patient with an exacerbated hiatal hernia.
  • Case report of a patient undergoing video-assisted thoracoscopic surgery for lung cancer.
  • Postoperative assessments including MRI to diagnose cerebral infarction and evaluate thrombus composition.
  • Implementation of mechanical thrombectomy due to contraindications for thrombolysis.
  • The patient developed acute cerebral infarction confirmed by MRI on postoperative day 1.
  • Successful emergent mechanical thrombectomy achieved complete recanalization (TICI 3).
  • Pulmonary vein thrombosis occurred due to external compression from an exacerbated hiatal hernia, despite a shorter pulmonary vein stump.

Main Result

Effect estimate: TICI 3 recanalization with single pass

Even an anatomically short pulmonary vein stump after left lower lobectomy can develop severe thrombosis leading to cerebral embolism if subjected to external mechanical compression from an exacerbated hiatal hernia.

Limitations

  • Single patient case report limits generalizability.
  • No control group or comparator treatment.
  • Findings are observational and hypothesis-generating rather than confirmatory.

Cite This Study

Shono et al. (2026) conducted a case report in Acute cerebral infarction after left lower lobectomy (n=1). Emergent mechanical thrombectomy using direct aspiration first-pass technique (ADAPT) was evaluated on Recanalization of left middle cerebral artery (M1 segment) occlusion with clinical neurological improvement (TICI 3 recanalization with single pass). Emergent mechanical thrombectomy using ADAPT achieved complete recanalization (TICI 3) in 31 minutes with dramatic neurological improvement in a patient with cerebral infarction after left lower lobectomy.
